AMERICAN GAS ASSOCIATION ANTITRUST COMPLIANCE GUIDELINES

Introduction

The American Gas Association and its member companies are committed to full compliance with all laws and regulations, and to maintaining the highest ethical standards in the way we conduct our operations and activities. Our commitment includes strict compliance with federal and state antitrust laws, which are designed to protect this country’s free competitive economy.

Responsibility for Antitrust Compliance

Compliance with the antitrust laws is a serious business. Antitrust violations may result in heavy fines for corporations, and in fines and even imprisonment for individuals. While the General Counsel’s Office provides guidance on antitrust matters, you bear the ultimate responsibility for assuring that your actions and the actions of any of those under your direction comply with the antitrust laws.

Antitrust Guidelines

In all AGA operations and activities, you must avoid any discussions or conduct that might violate the antitrust laws or even raise an appearance of impropriety. The following guidelines will help you do that:

Do consult counsel about any documents thattouch on sensitive antitrust subjects such aspricing, market allocations, refusals to dealwith any company, and the like.

Do consult with counsel on any non-routinecorrespondence that requests an AGAmember company to participate in projects orprograms, submit data for such activities, orotherwise join other member companies inAGA actions.

Do use an agenda and take accurate minutesat every meeting. Have counsel review theagenda and minutes before they are put intofinal form and circulated and request counselto attend meetings where sensitive antitrustsubjects may arise.

Do provide these guidelines to all meetingparticipants.

Do not, without prior review by counsel,

have discussions with other membercompanies about:

your company’s prices for products, assets or services, or prices charged by your competitors

costs, discounts, terms of sale, profit margins or anything else that might affect those prices

the resale prices your customers should charge for products or assets you sell them

allocating markets, customers, territories products or assets with your competitors

limiting production

whether or not to deal with any other company

any competitively sensitive information concerning your own company or a competitor’s.

Do not stay at a meeting, or any othergathering, if those kinds of discussions aretaking place.

Do not discuss any other sensitive antitrustsubjects (such as price discrimination,reciprocal dealing, or exclusive dealingagreements) without first consulting counsel.

Do not create any documents or other recordsthat might be misinterpreted to suggest thatAGA condones or is involved in anticompetitivebehavior.

We’re Here to Help

Whenever you have any question about whether particular AGA activities might raise antitrust concerns, contact the General Counsel’s Office, Ph: (202) 824-7072; E-mail: [email protected], or your legal counsel.

Project Statement Form Return to Derek Deskins ([email protected])

Fire Protection Research Foundation, One Batterymarch Park, Quincy, MA 02169-7471

1) Proposed Project Title:

Investigating the Suitability of Biogas for Use in Fuel Gas Distribution Systems

2) Problem Statement (One or two sentences addressing “What is the research or data need?”):

Biogas includes landfill gas, digester gas and other “renewable” sources that can produce flammable gas, potentially for use in fuel gas distribution systems that serve buildings and provide energy for other uses. However, there currently are concerns about burning biogas in appliances because of its varying energy content and a lack of knowledge of its properties, such as corrosiveness and density that would need to be identified prior to writing a code or standard to address its use.

3) Research Objective (One or two sentences addressing “What is needed to solve the problem?”Examples include: Develop guidance for a specific issue, Determine effectiveness of currentcode/standard requirement):

We need to determine the current “state of the art” with respect to biogas quality standards currently used in the world. This information will help the National Fuel Gas Code Committee determine whether or not to pursue writing code text to address the use of biogas in the National Fuel Gas Code.

4) Project Description (One or two paragraphs on study design & expected tasks. Project tasks caninclude literature reviews, data collection, loss summaries, field usage surveys, code comparisons,statistical analysis, computer modeling, hazard analysis, risk assessments, fire testing,recommendation development, and gap identification.):

This project would begin by conducting a literature review to identify the current state of the art with respect to biogas. It would include identifying all the known standards related to biogas specifications and handling and assessing the success of efforts to implement biogas around the world. After that, it would be necessary to determine the feasibility of including requirements for biogas in the National Fuel Gas Code.

5) Data Collection (If data collection is part of the project scope, does data exist? If data exists, is itavailable to be used in the study? Please identify potential data sources.)

There are various standards on biogas that are used in different countries of the world. For example, Canada has standard B149.6. There are also ISO standards and other organizations and publications that are dedicated to the use of biogas.

6) Relevant NFPA Document(s), Technical Groups, or Foundation strategic research agenda item &How Project Will Impact:

The following NFPA standards and their associated technical groups were identified at a meeting of the National Fuel Gas Code Committee as potentially having an impact or being impacted by this project: NFPA 54, NFPA 85, NFPA 86 and NFPA 87.

7) Organizations That Could Possibly Fund (Examples: government grants, industry consortia, stakeholders):

The American Gas Association is a potential partner for funding because biogas would most likely be used as a substitute or even be mixed with natural gas in fuel distribution piping systems. 8) When Do You Need Project Deliverables (when is information needed to coordinate with document

revision cycles, sense of urgency): Regarding NFPA 54, the next cycle begins with the proposal closing date of July 6, 2015. 9) Submitted By (Staff Liaison/TC Chair/etc) and Date Submitted: Bruce Swiecicki NPGA Alternate member on National Fuel Gas Code Committee Appointed by Chairman Tom Crane to serve as chairman of Biogas Task Force 12/29/2014

April 12, 2016

Paul W. Cabot Administrator, National Fuel Gas Code American Gas Association 400 North Capitol Street, NW. Washington, D.C. 20001

Re: Regular ANSI Audit Report

Dear Mr. Cabot

Please find enclosed the report of audit of ASC Z223 and ASC Z380 conducted by Leslie Block in February 2016. Please respond to each of the non-compliances and the corresponding recommendations identified in section 8 of the audit report. In accordance with clause 6.4 of the ANSI Auditing Policies and Procedures, you are required to provide ANSI with any comments, plans, and timetables for corrective action within 30 days of receipt of this letter or request an extension from the Director of the ANSI Standards Developer Audit Program if you cannot meet this deadline. In addition, please provide your response and any attachments in electronic format.

In accordance with Clause 12 of the ExSC Operating Procedures, a list of affiliations of the members of the Executive Standards Council is provided for your information. Clause 12 states that “Typically a potential conflict of interest arises when a member of the ExSC participated in activities integral to the particular issue under review or that person is employed by, or a member of the governing body of, the relevant standards developer or other entity as applicable. Similarly, a conflict of interest usually does not exist by virtue of the fact that a member of the ANSI committee participated in the development of standards by a particular standards developer or is a member of that standards developer.”

In connection with the implementation of the ExSC's Conflict of Interest procedures, I have provided a current ExSC roster for your information and review. Please review the list and let me know if you believe that any member has a conflict of interest.

If you assert that a member of the ExSC has a conflict of interest, you are required to state the reason(s) for your belief. A member (or his/her employer) of a reviewing body having a conflict of interest with the auditee shall not be allowed to receive or review a copy of the audit report and will not be allowed to participate in the discussion of the audit unless otherwise agreed to by the auditee. The conflict of interest procedures applicable to the reviewing body shall apply.

The audit report and any comments received will be provided to the ExSC for their review and determination in accordance with clauses 4.1.3 and 4.1.4 of the ANSI Essential Requirements. When a final decision has been made by the ExSC it will be provided to you in writing and it may be appealed pursuant to the applicable procedures.

75

As part of the audit process, the auditor makes suggestions with the intent to recommend improvements to the operation of ASC Z223 and ASC Z380, and do not in any way indicate that ASC Z223 and ASC Z380 are in non-compliance with the ANSI Essential Requirements. The suggestions may not be feasible or practical for ASC Z223 and ASC Z380 to implement. They are intended only as suggestions and will be left to the discretion of ASTM to accept any or all of them. There is no need for ASC Z223 and ASC Z380 to respond to any of these suggestions. These suggestions can be found in an attachment to this letter. I thank you for the cooperation of the AGA staff during the audit. Please do not hesitate to contact me if you have any questions. Sincerely, Jay Moskowitz Director, Standards Developer Audit Program Encl: List of Suggestions for ASC Z223 List of Suggestions for ASC Z380

Attachment B – List of Suggestions for ASC Z223

# § Suggestion Text 1 7 The auditor suggests that ASC Z223 consider revising its procedures as

follows: 1a 7B Revise Section 3.5.3.1 to add “less abstentions,” which is stated in Section

3.5.1.4, but should be included in the language regarding ASC Z223’s numerical consensus requirements.

1b 7C Revise Section 6.2.3 to add specific criteria or metrics to define poor participation.

1c 7 Revise Section 8.7 to add that ASC Z223 will notify ANSI in the case where a standards project is discontinued.

1d 7 Revise Section 10.10 to state that ASC Z223 will provide the requestor with the interpretation response “in writing.”

2 7 The auditor suggests that ASC Z223 consider incorporating its Antitrust Policy into its accredited procedures. Having all of the policies and procedures required by ANSI in one document eliminates confusion as to identifying the most recently approved version of a policy or procedure, and provides easy reference to currently applicable requirements.

3 7 The auditor suggests that ASC Z223 consider adopting in its procedures statements that it will adhere to the current version of ANSI’s Commercial Terms and Conditions Policy and Antitrust Policy. In this way, ASC Z223 would be in compliance with the ANSI requirement to have the required policies, but would not need to revise its policies and procedures with each change in the ANSI policies.

4 7D The auditor suggests that ASC Z223 consider whether it wants to allow technical appeals. The ANSI Essential Requirements require only that standards developers allow procedural appeals, and it is within the developer’s prerogative whether to allow technical appeals.

5 7D The auditor suggests that ASC Z223 revise ASC Z223’s Appeals Policy to provide that the appellant will receive a copy of the appeals decision in writing.

6 7 The auditor suggests that ASC Z223 consider including an explanation of the ANSI and ASC Z223 standards development and approval processes on the AGA web site.

7 The auditor suggests that ASC Z223 consider exploring additional ways in which electronic media, including online voting, can be used in the standards development and approval process. The use of electronic media can increase the efficiency and reduce the cost of the standards development process.

8 7 The auditor suggests that ASC Z223 may wish to provide training to volunteers on key requirements of consensus processing. Training is beneficial to the participants and can assist in ensuring that the requirements for obtaining consensus are met efficiently and effectively.

9 The auditor suggests that ASC Z223 develop a one- or two-page guideline to be used for training staff members who may be assigned responsibilities for following ANSI requirements in development of ASC Z223 standards. Such

77

internal guidelines will assist in the implementation of the standards development process and can assist in the reduction of errors and inefficiency potentially caused by staff turnover.

10 7 The auditor suggests that AGA participate on the ANSI Organization Member Forum (“OMF”). Participation is a benefit of ANSI membership and will provide ASC Z223 with an opportunity to provide input into proposed changes in ANSI policies and procedures and to have advanced information of these changes for implementation. The OMF typically allows participation via teleconference.

11 The auditor suggests that ASC Z223 consider developing a one- or two-page summary of development of each standard that indicates very briefly how the project proceeded, when the various procedural actions were taken and in which file relevant information can be found, as an aid to external or self-audit activities and training purposes.

ASC Z223 announces the availability of the new edition of the Code on AGA’s website and via TechStreet and AGA’s eNewsletter.

8. Audit Recommendations:

A. The auditor found areas of non-compliance and procedural concern. The followingrecommendations are made to address these non-compliances and procedural concerns:

i) The auditor recommends that ASC Z223 revise ASC Z223’s Procedures andprovide a copy to ANSI to initiate the reaccreditation process as the auditor foundthat substantive changes are required to bring those procedures into agreementwith the currently applicable ANSI Essential Requirements. The specificrecommended revisions are:

a. Revise Section 3.4.3 to state that Standards Action comes out weekly.

b. Revise Section 3.5.5.1 to add “and rationale” after results;

c. Revise Section 3.5.5.1 to add “in writing” after notify with regard to the right toappeal;

d. Revise Section 3.5.5.3 to state that unresolved objections, along with attempts atresolution, will be provided to the committee in order to afford them theopportunity to respond, reaffirm, or change their vote;

e. Revise Section 8.0 to correspond with NFPA’s current standards developmentpolicy;

f. Revise Section 8.8.2 to state that public review commenters will receive a writtendisposition of their comments with the reasons therefore; if the comments remainunresolved, the commenters will be informed in writing of the right to appeal;

g. Revise Section 8.8.2 to add that unresolved comments from ANSI public reviewalong with attempts at resolution will be recirculated to the consensus body togive them the opportunity to respond, reaffirm or change their vote; and

h. Revise the Patent Policy compliance statement in Section 12.0 to add the words“most current version” before “ANSI Essential Requirements.”

ii) The auditor recommends that the non-compliances listed in this audit report bereviewed at the next scheduled audit to verify that corrective action was taken.

9. Post Audit Conference

The findings, recommendations and comments were discussed during a post audit teleconference call that was held on April 8, 2016 . Those who participated were Paul Cabot, ASC Z223/NFPA 54 Secretary, AGA, Michael Bellman, ASC Z380 Secretary, AGA and Jay Moskowitz, Director, ANSI Standards Developer Audit Program.

The auditor would like to express appreciation for the cooperation extended by the AGA staff.

6/7/2016

1

A Quick Summary of Methods and Issues

John S. RobertsRimkus Consulting Group

6/21/2016NFPA 54 Phoenix, AZ 1

Natural Gas – Odorant added at point of transfer◦ City Gates◦ Added to flowing gas, usually 0.5 to 1 lb per

MMSCF Propane – Added at a point when the propane

is transported by truck or rail◦ Pipeline terminal, refinery, rail terminal or gas plant◦ Added to liquefied gas◦ Gas becomes odorized when odorant and propane

vaporize


Usually tertiary Butyl Mercaptan and some other component

Other components are Thiophane, n-Propyl Mercaptan, Isopropyl Mercaptan, sec-Butyl Mercaptan, Dimethyl Sulfide (DMS) or Methyl Ethyl Sulfide (MES)

DMS and MES are diluents and have a much poorer odor than the mercaptans

Added using injection or bypass odorizers to flowing gas


85

6/7/2016

2

tertiary-Butyl Mercaptan (TBM) used as it has a very good odor and is the most stable mercaptan odorant

Best stability to oxidation and adsorption on soils

Thiophane has some use, but may be more historic usage. Also does not oxidize

The worst at soil adsorption and pipe adsorption

The odor is not comparable to mercaptans


Flow rates – Gas must flow – Static gas will not retain odorant

Within a house or most commercial applications this is not a problem as the volume of gas is quite low and pressures are low

With a gas distribution system with miles of pipe at high pressures, this becomes a significant problem


Hydrocarbon liquids – pooling of liquids in distribution lines can remove odorant due to absorption.

A problem that can be found in gas producing areas and is a function of the price of propane and other liquids found in Natural Gas Liquids (NGLs) (typically)

TBM is a liquid with a melting point of 31 F so requires a diluent to keep the material in a liquid condition at much lower temperatures


86

6/7/2016

3

New lines – Gas distribution systems can have long stretches of new gas lines. These can become adsorption sites, and may need to have supplemental odorization. New lines need to be monitored for odorization.


Ethyl Mercaptan is the only odorant for propane currently utilized in the US or Canada

Added at a rate if 1.5 pound odorant per 10,000 gallons of propane, although standard is 1 pound per 10,000 gallons

Added to liquefied propane using a pump or some other method


Propane/Odorant is a problem in vapor-liquid equilibrium

Propane has a boiling point of -44 F. Ethyl Mercaptan (EM)has a boiling point of 95

F This means that EM and propane are not

found in the vapor at the same concentration as in the liquid

The ratio of the concentration of EM in the vapor to EM in the liquid is the K-factor


87

6/7/2016

4

This changes with respect to temperature◦ K = 0.11 at -10 F◦ K = 0.22 at 95 F

This means that at 95 F, the amount of EM in the vapor is 22% of the amount of EM in the liquid

The odorant level is set up with this in mind Other odorants, such as thiophane, require much

higher concentrations, which is why 6.4 pounds per 10,000 gallons is utilized◦ K = 0.007 at -10 F◦ K = 0.033 at 95 F


Oxidation◦ Mercaptan odorants can be oxidized Natural gas by rust (Fe2O3) in pipelines Propane by rust in tankage◦ Thiophane is not oxidizable by rust

Adsorption◦ All odorants can be adsorbed by surfaces◦ This can be piping, clothing, concrete, etc.◦ The higher the molecular weight the worse the

problem, typically


Adsorption – Soil◦ This is a slightly different problem◦ Odorants are adsorbed by soil in the following

order: Clay >> Silt > Sand > Gravel This order is in terms of particle size of particles and

also the surface area of each entity Clays have very high surface areas◦ Interestingly, the ease of movement of gas through

these entities is: Gravel > Sand > Silt >> Clay


88

6/7/2016

5

Adaptation – Getting used to the odor◦ One must respond immediately to a gas odor

Recognition◦ Misidentification – Is that the odor of a dead rat or

is it a gas leak?◦ Scratch and Sniffs have improved this issue for

natural gas and propane◦ The increased presence of propane in the

environment (propane grills) has increased propane odor recognition


Anosmia – No sense of smell – not a well defined population but probably about 0.2% of population

Aging – In general, as one grows older your nasal acuity decreases.

One must be in the presence of gas in order to smell the odorant.

Sleep – Thought to be a problem, but there are no real studies done on this issue. Last attempt was made in the 1930’s. Could be a subset of Adaptation

Public Comment No. 31-NFPA 54-2016 [ Sections 3.3.78.3, 3.3.78.4 ]

Sections 3.3.78.3, 3.3.78.4

3.3.78.3 Design Pressure.

The maximum operating pressure of a gas piping system permitted by this code, as determined by thedesign procedures applicable to the materials involved.

3.3.78.4 Maximum Working Pressure.

The maximum pressure at which a piping system can be operated in accordance with the provisions of thiscode of a pressure vessel as determined by the design procedures applicable to the materials involved .

Statement of Problem and Substantiation for Public Comment

It is not clear what the difference is between design pressure and maximum working pressure. The ASME B31.3 makes a clean distinction. See ASME B31.1 (2012) para. 322.6.3 "Pressure Relieving Devices" . It would be very helpful if NPFA 54 followed this same distinction.

Per ASME B31.1, design pressure is essentially the highest stresses possible a gas piping system can see when considering the most severe conditions that can occur (extreme temperature, flows, pressure, etc.). What makes a gas piping system uniquely different than a pressure vessel is that a gas piping system is handling significantly higher flows. Significant changes of large flow rates result in difference stresses and conditions that pressure vessels don't see.

NPFA 58 defines 1) Maximum Alllowable Working Pressure as "the maximum pressure at which a pressure vessel is to operate asdescribed by the ASME code". 2) Design pressure as "The maximum pressure at which the equipment or system is designed to operated".

5.5.1 Gas Piping System Operating Pressure Limitations.

The maximum design maximum operating pressure for any gas piping system shall not exceed 125 psi(862 kPa).


1) I would recommend adding "gas" to piping system for consistent use of the phrase "gas piping system".2) I would recommend deleting “design”. Current language implies operating pressure and “design” operating pressure could be different. Also, the design of the gas piping system may be greater than 125 PSI, but it should never operate above 125 PSI.

5.5.4 Maximum Design Maximum Operating Pressure in Buildings.

The maximum design operating pressure for any piping systems located inside buildings shall not exceed 5psi (34 kPa) unless one or more of the following conditions are met:

(1)

(2) The piping joints are flanged and all pipe-to-flange connections are made by welding or brazing.

(3) The gas piping system is located in a ventilated chase or otherwise enclosed for protection againstaccidental gas accumulation

(4) The gas piping system is located inside buildings or separate areas of buildings used exclusively forone of the following:

(5) Industrial processing or heating

(6) Research

(7) Warehousing

(8) Boiler or mechanical rooms

(9) The gas piping system is a temporary installation for buildings under construction.

(10) The gas piping system serves appliances or equipment used for agricultural purposes.

(11) The gas piping system is an LP-Gas piping system with a design an operating pressure greaterthan 20 psi (138 kPa) and complies with NFPA 58.


1) I would recommend using the phrase “gas piping system” for consistency and that 's what the section covers. One might think a piping or a piping system is different than a gas piping system. 2) I would recommend deleting “design”. Current language implies operating pressure and “design” operating pressure could be different. Design operation pressure makes it appear that I can’t design a piping system to operate at pressures greater than 125 PSI rather than having a gas piping system operating at pressures greater than 125 PSI. Alternative would be to use the defined term "Design Pressure" rather than "design operating pressure" if that is the original intent.

AGA is in favor of allowing Schedule 10 carbon steel pipe where a press fit connector is required as proposed in CI No. 63. However, the way the Code refences to the product stanards in Section 5.6.2.2 is not completely accurate. The ASME standard is a dimenational standard (that has schedule 10 designations) while the two ASTM standards are material composistion standards (and do not have shedule 10 designations). Therefore the ASME standard and one of the ASTM standards need to be required together to ensure that carbon steel pipe is correctly specified (especially for schedule 10) . ASME B36.10M states that “The dimensional standards for pipe described here are for products covered in ASTM specificaitons.” Note, B36.10M does not state which ASTM standards. ASTM A53 is the most commonly used “black” steel pipe.

Public Comment No. 35-NFPA 54-2016 [ Sections 5.8.1, 5.8.2 ]

Sections 5.8.1, 5.8.2

5.8.1 Where Required.

A line An appliance shall have a gas appliance pressure regulator or gas appliance pressure regulator,as applicable, where the supply pressure is greater than or varies beyond what the burner manifoldpressure requirements are for the appliance. A line pressure regulator shall be installed where the gassupply pressure exceeds the maximum allowable inlet pressure of the appliance served.

5.8.2 Listing.

Line pressure regulators shall be listed in accordance with ANSI Z21.80/CSA 6.22, Line PressureRegulators when the outlet pressure is set to 2 PSI or less .


PI #193 still does not clearly define when a line regulator or gas appliance regulator is required. Current language permits two options:

1) To install a gas appliance pressure regulator, which is not required to be listed, to be used to drop the inlet pressure to ½ PSI or less for an appliance that is rated for ½ PSI max, or

2) To install a line pressure regulator, which is required to be listed (see 5.8.2), to be used to drop the inlet pressure to ½ PSI or less for an appliance that is rated for ½ PSI max.

I assume the committee had a different intent.

Additionally, the current language in 5.8.1 in combination with 5.8.2, which requires line pressure regulators to be listed, has an unintended consequence. A line pressure regulator listed in accordance with ANSI Z21.80/CSA 6.22 is only permitted to have a maximum outlet pressure of 2 PSI and may be rated for maximum 10 PSI inlet. For industrial and commercial applications this can create conflicts. Having to knock down a 10 PSI point of delivery pressure to 2 PSI does not make sense if the burner needs 5 PSI pressure. Or if the point of delivery pressure is 60 PSI, there is no line pressure regulator listed in accordance with ANSI Z21.80/CSA 6.22 with a 60 PSI pressure rating.

In my view, the intent of a line pressure regulator listed in accordance with ANSI Z21.80/CSA 6.22 has to do with an installation where the appliance is rated for 0.5 PSI (typically this is an appliance listed to any one of the ANSI Z21/83 series standards) and the supply pressure is greater than 0.5 PSI. Listing to ANSI Z21.80/CSA 6.22 should be required only when its outlet pressure is 2 PSI or less. Such an approach would permit the pressure to be staged from a pressure higher than 2 PSI (e.g. 60 PSI) down to 10 PSI using a non-listed line regulator upstream, and then the final stage from a pressure higher than 2 PSI (e.g. 10 PSI) down to 0.5 PSI using a listed line regulator.

5.9.2.2

Where piping systems serving appliances designed to operate with a gas supply pressure greater than 14in. w.c. are required to be equipped with overpressure protection by 5.9.1, each overpressure protectiondevice shall be adjusted to limit the gas pressure to each connected appliance as required by theapplicable appliance standard or where no applicable appliance standard applies, as required by theappliance manufacturer’s installation instructions.


NFPA 86 and NFPA 37 are updating the overpressure protection requirements to reflect the changes that took place due to the 2015 edition of NFPA 54. Thus, I recommend that NFPA 54 first require that the overpressure protection detailed in the applicable appliance standard be followed (e.g NFPA 86 or NFPA 37, etc) as the primary requirement, and as secondary where there is no applicable appliance standard, then the manufacturer's instructions are to be followed.

Where the conduit originates and terminates within the same building, the conduit shall originate andterminate in a an accessible portion of the building where gas leakage from the conduit would be detectedby the occupants. The conduit terminations shall and shall not be sealed.


The first revision draft change was accepted without evidence that the current installation practice is unsafe. The requirement that a gas leak be detectable by the occupants is unenforceble since the term is undefined, and even if defined, is open to interpertation since an individual’s ability to detect vaires. The code currently does not specify the installation location for all other gas piping such that leaks are detectable, assuming any leak within the building will be noticed.

7.8.2 Point of Delivery Service Valve.

Where the point of natural gas delivery is the outlet of the service meter assembly or the outlet of theservice regulator, a full-size shutoff valve shall be installed downstream from the point of delivery.


The revision would require the installation of a shut off valve after the point of delivery. The proposal was submitted based on a convenience for the serving gas supplier and no safety related evidence was presented to justify the additional valve. There is some concern that having an accessible valve with an easy to shut off valve handle may be subject to tampering. Also, the code would not require the valve termination be capped for new construction where the building piping has not yet be pressure tested or where the appliances have not yet been installed. This may lead to cases where the valve is mistakenly opened prior to complete installation. The new code text does not provide minimum location criteria and does not define what “full size” means (pipe diameter, flow, etc.). The current code does not prohibit a gas supplier from installing a customer owned valve where the gas provider and builder have arranged safeguards for such installations.

Public Comment No. 81-NFPA 54-2016 [ New Section after 7.12.2 ]

CSST Spacing

7.13.3 CSST Spacing. CSST shall be spaced a minimum of 6 inches from any metallic component,grounded metal parts and electrical conductors.*


The problem is that arcing to CSST caused by lightning-induced voltage differences between the CSST and metal bodies create punctures that may lead to gas ignition. Present methods for protecting against this hazard need augmentation to minimize the development of arcing. This comment restates proposals made in Public Inputs #110 and #146.

The proposals were rejected by the committee in the First Draft with the following reason provided: ‘No substantiation has been provided to justify the 6 inch separation. The distance would be difficult to preserve and control post construction and difficult to enforce by code officials. This proposed language ignores existing methods for mitigating arcing damage such as bonding and arc resistant jackets with no substantiation that the 6 inch separation improves safety.'

The proposal does not ignore existing methods for mitigating arcing damage. It proposes additional means to minimize the probability of the formation of the arc to use in concert with existing means to provide a defense in depth against arcing for the improvement of CSST safety. Means of minimizing arc damage to CSST once the arc has occurred should be a secondary means of protection and not solely relied upon for safety.

The proposal for separating CSST from metal media originated, in part, from my review of the GTI reports of 2013. I conducted peer review of the March 2013 draft and noted at that time (April 2013) that the test voltages were far lower than what can occur in observed lightning events. The voltages used in the GTI reports were limited by the test equipment to an order of magnitude less than realistic lightning voltages. The GTI report also found that CSST damage is correlated proportionally to voltage developed.Another aspect leading to development of the proposal was that CSST directly bonded in a manner meeting the NFPA 54 has been observed to suffer puncture from arcing, as was pointed out in PI# 110. This fact proves that voltages far higher than the testing used in the GTI reports are being experienced in the field. (I point out that no attempt was made to correlate the assumed voltage used in the GTI report to those experienced in the field was performed. I commented on this matter during my review of the GTI report in April 2013.) Moreover, personal experience in investigating CSST punctures from lightning events shows that proximity to grounded metal bodies provides a likely point of arcing for CSST.

The development of voltage between CSST and other grounded metallic components installed in a structure may increase due to the grounding resistance, from non-ideal installations outside of the assumptions of the GTI report, (including length and placement of the bonding conductor) from greater than assumed currents and risetimes of the lightning event, or other as yet unidentified sources. Implementing any amount of separation provides an additional safety factor and a first line of defense to reduce the probability of arc formation to CSST.

Ample substantiation was provided in Public Input #110. The physics of arc formation dictates that any separation would retard the formation of potentially damaging arcs to CSST. The value of 6 inches was provided and justified by the dielectric breakdown value of 6 inches of air, approximately 450 kilovolts, which more closely matches voltage differences that may occur within a structure from lightning events, even with the implementation of direct bonding. Even 2 inches of separation (as mandated by State of Indiana Code) would quadruple the present measure of safety provided by any insulating jacket of CSST. Separation provides an additional measure of safety against realistic voltages that can develop during lightning strikes.

Moreover, extracts of legislated codes from some jurisdictions were provided in PI #110 as a means to demonstrate that the implementation of separation (between 2 to 6 inches) is indeed practical.

Finally, it was noted in Public Input #110 that CSST manufacturers recommend separation.

Reducing the probability of lightning-induced arcing to CSST needs to be the primary consideration for CSST safety. Other means of protection involving damage reduction to CSST once an arc has formed is secondary, a last line of defense upon which there should not be sole reliance. Separation, used in concert with other means of protection such as direct bonding and arc-resistant jacketing maximizes safety.

This editorial change clarifies that the requirements of 7.12.2 for non arc-resistant jacketed CSST are not applicable to the new bonding requirements arc-resistant CSST for arc-resistant CSST are located in 7.12.3. This clarification is important, as a code user could interpret that the requirements of 7.12.2 apply to all CSST, and not read 7.12.3.

7.12.2.1

The bonding jumper shall connect to a metallic pipe, pipe fitting, or CSST fitting between the point ofdelivery and the first downstream CSST fitting .


This comment is a resubmission of PI-159 with a revised Substantiation to address the apparent misunderstanding of intent of the original proposal. The length of the bonding jumper and the establishment of ground-level potential equalization are not mutually exclusive. They address different aspects of the protection of a CSST installation to a lightning threat. The protection against lightning consists of both external and internal protection systems. NFPA 54 has chosen to focus their efforts only on internal protection against lightning threats. The function of the internal LPS is to prevent dangerous sparking within the structure, usingequipotential bonding or separation distance [1]. NFPA 54 seems to be basing its requirements solely on the content of the various versions of the GTI report. This report seems to focus primarily on the reduction of the probability of dangerous sparking to address the reduction of susceptibility of CSST to a lightning environment. This specifically is a primary purpose of the internal lightning protection system.A basic principle of national and international lightning protection standards is the development of an equipotential plane at the ground level [1][2][3][4]. This fundamental component is basic not only to protection against direct strikes but also to nearby strikes and strikes to and near incoming conductors. It provides a common ground potential for incoming conductors but also provides a current division limiting the incoming current that can appear on the CSST. It is important that the committee note that each of the scenarios identified in the GTI report includes a bond or ground at the service entry or between there and the first downstream fitting as required by the amended text. Without this current division the entire 10 kA will flow on the CSST, resulting in a charge at the potential arcing point sufficient to create a breach in the CSST. The bonds/grounds at the service entry will also decrease the susceptibility to those probable cases where the threat is greater than the 10 kA limit used in the GTI analysis. The asterisk is added to identify supplemental information is proposed in Annex A.References:1.

7.12.2.3*

The length of the jumper between the connection to the gas piping system and the grounding electrodesystem shall not exceed 75 25 ft (22 8 m). Any additional grounding electrodes installed to meet thisrequirement shall be bonded to the electrical service grounding electrode system or, where provided,lightning protection grounding electrode system.


Shorter direct bonding of the CSST to the grounding electrode improves safety. 75 ft is not adequate to minimize the probability of arcing to the CSST.

Prevention of an arc forming onto the CSST needs to be the primary safety consideration for regulating the bonding. Limitation of the energy delivered once an arc is formed is secondary.

The value determined by the committee, using the referenced GTI report, is based on the amount of current that is shunted into the grounding circuit from a direct bond to the CSST. Shunting the current limits the energy delivered to the CSST, enhancing its ability to survive an electrical arc without puncture. However, the length of the bond needed to minimize the probability of an arc forming in the first place is not considered.

The voltage developed from current flowing through the direct bond is dependent upon two conductor properties, resistance and inductance. It is well known that voltage differences occur from current flow through a resistance and from current risetime imposed upon the inductance. Such voltage differences can far exceed test scenarios conducted for CSST.

For example, a #6AWG bonding wire has approximately 1.23 microHenry per meter inductance and a resistance of 0.0013 ohms per meter. Using realistic lightning risetimes (which exceed the values assumed by the GTI report) and only considering inductance, a 75-foot run of #6AWG wire will develop a voltage drop of approximately 307 kilovolts. However, a 25-foot run will only develop approximately a 100 kilovolt drop. The reduction achieved by the shorter distance puts the voltage much closer to the insulating value of typical CSST jacketing, which is on the order of 60 kilovolts. CSST jacketing cannot defend against the voltage developed through the longer bonding length.

Also, as the GTI testing shows, ‘shorter is better’ (GTI 2015, p. 28) with respect to bond length. The shorter length will far better limit the amount of current injected into the CSST in the event of an arc, or conduction by contact, thus greatly enhancing the survivability of the CSST against puncture through an electrical arc. As a peer reviewer of the GTI report (GTI, 2013) I observed at the time (April 2013) that some variables used were minimal. For example, the lightning risetimes, current magnitudes used and test voltages used were minimal compared to well-known lightning phenomenology. (Rakov, 2002,) The known values far exceed those used in the report, which is the basis for the 75-foot bonding conductor length. A greater safety factor is necessary to account for these minimal values through using a shorter bonding conductor length. The shorter bonding conductor length overcomes the uncertainties, limitations and questionable assumptions used in determining the 75-foot value. These include the assumption of consistently low grounding electrode resistance, use of minimal lightning current risetimes, below-average current magnitude of the lightning strikes, neglecting the restrike current in real lightning events, low voltages used in testing compared to real lightning events, and conditions resulting from imperfect installations. The shorter length of the bonding conductor provides an additional and necessary safety factor to account for these problems.

Shorter bonding length (of 25 ft) provide a greater degree of safety through better limiting the voltage drop between CSST and other metal components thereby minimizing the probability of the development of an electric arc. The shorter bonding length complements other protective measures such bonding to shunt a larger amount of current to ground, (minimizing energy delivery to the CSST, also better accomplished through the same shorter bonding conductor) spacing of the CSST (see PC#81 & PI#110, minimizing probability of arc formation) and

insulating or arc-resistant jacketing (reducing the damage from an arc.) Used in concert, these protective measures provide a greater degree of safety for CSST installations than any one alone.

The difficulty of lab testing to field conditions creates the need to be more conservative as a safety factor in design and installation. A value of 75 ft. is not conservative, and may not include various reported situations involving CSST damage. The 50 ft. value is more conservative, and a value below this would be preferable.

In Public Input No.155 & Public Input No. 154, the committee response of "75 feet was established" and "The committee has testing that indicated 75 feet of 6 AWG is adequate" was used as substantiation to not accept the proposed bonding distance of 50 feet. Let the record clearly show that the GTI report did not test the 75 feet scenario? This distance was established by a simulation done by PowerCet and the perception that this model is the reality is premature at best. The model used by PowerCet was never disclosed or circulated for peer review to any other subject matter experts, other committees or any other body technical body. The committee response leads the general public to believe that this distance is 1) verified by laboratory testing and 2) conservative in nature, as all safety standards should be when there is a topic that of this nature. The 75 feet distance meets neither of these and therefore should be changed to a shorter distance in the interest of public safety & welfare. Another point that the committee response cites is that "The committee believes the GTI report did receive peer review, which included members of the NFPA 780 committee..." As a member of the NFPA 780 committee, this report never came before our committee for comment. The response indicates that more than one member of the 780 committee reviewed the GTI Report. To date, only Dr. Tobias has indicated that he has been asked to provide a review of the report, not multiple members. The committee did not cite anything or publish for public review any of the comments submitted by Dr. Tobias. In fact I can find no record of any peer reviewed comments on the GTI report being published. The committee has an obligation and duty to seek outside expertise concerning this matter. In the Standards Council item #10-3-20, Decision D#10-2, the specific language given was "drawing on the expertise, as appropriate, of the members of NFPA 70, National Electrical Code, NFPA 780, Standard for the installation of Lightning Protection, and from other appropriate organizations.." These guidelines have not been fulfilled as there is no record in the NFPA 54 committee proceedings, to indicate that any members of either of those committees have been consulted and have their input made public.

7.12.2.3*

The length of the jumper between the connection to the gas piping system and the grounding electrodesystem shall not exceed 75 exceed 50 ft (22 15 m). Any additional grounding electrodes installed to meetthis requirement shall be bonded to the electrical service grounding electrode system or, where provided,lightning protection grounding electrode system.


NFPA 54, A.7.12.2 indicates the maximum length of the bonding connection was established based on Gas Technology Institute Project Number 21323 report, “Validation of Installation Methods for CSST Gas Piping to Mitigate Indirect Lightning Related Damage”. The lengths for bonding connections in the GTI report are based on simulations using circuit models that are yet to be fully validated by independent testing and analysis. Small errors in the model can lead to large errors in the simulation results when the parameters are multiplied by a factor of up to 100. See below for a discussion on errors that could be assumed in the resistance-to-earth values used in the simulations and the discussion in PI-162 that discuss variations in the circuit models that can be assumed for the simulation of the CSST and The committee resolution statement for PI-162 states “75 feet was established during the 2015 revision cycle as a conservative value based on the available research.” However, the analysis provided by GTI is based solely on a set of values established in the report without consideration of other values cited from available peer-reviewed research identified in the substantiation for PI-162. The GTI analysis also uses optimistic values for grounding resistances for electrical service entries and incoming gas lines. NFPA 70-2014, 250.53(A)(2) provides an exception to the supplemental electrode requirement if a single grounding electrode has a resistance to earth of 25 ohms or less but the reality is that most residential applications require 2 electrodes. There is no upper limit for the resistance to earth as long as the supplemental electrode is installed. In typical residential installations the actual resistance to earth can be 4 to 5 times the value cited in the simulations. The same is true for the 10 ohms to earth values used for a grounded gas line. It is uncommon to find a 10-ohm resistance to earth at the incoming gas line even when a driven rod is installed at that location.The committee resolution statement for PI-162 also identified that the committee believes the GTI report was properly peer reviewed, which included members of the NFPA 780 committee, appropriate for this type of research and its intended purpose. It is suggested that the committee identify any members of lightning protection community not associated with the development of the report that performed the peer reviews because we have found only one. Peer review by members of the lightning protection community seems to be appropriate for this type of research and its intended purpose. Only one member of NFPA 780 (not members as stated) has been identified as a reviewer, John Tobias. Peer review by the lightning protection community could also help the committee understand the relevance of ground potential rises and the benefit of ground-level potential equalization in addressing the CSST lightning issue. In summary, the simulations currently reported do not address the entire spectrum of ranges of values to represent equivalent circuit parameters for the CSST reported in peer reviewed literature (discussed in the substantiation to PI-162). In addition, the simulations have not addressed all sizes of CSST. The earlier simulations did not identify the size of CSST used in the simulation. The later simulations identified ¾-inch diameter CSST only. None of the simulations address the effect of more realistic resistance to earth values for incoming power and gas lines. Finally, it is unclear from the information provided in the report that the failure criteria used in the report is a worst case condition. Figure 54 of the GTI report shows the results of an Arc Entry test to a 1” diameter CSST when 864 A/ 0.507 C was delivered, resulting in burn-through in the pipe sidewall. This test was repeated twice with the same results. There does not appear to be a clear correlation between the measured charge susceptibility of 0.5 C and the Q*t = 300 criteria recommended in the GTI report (nor whether the Q*t = 300 criteria was used as recommended).Until additional simulations are performed and the arc-sensitivity is better defined, it is suggested that the values given in the report should not be considered as conservative as stated and therefore it suggested that a more conservative bonding conductor limitation would be 50 feet of #6 AWG. If the simulations indicate that known events documented in the NFPA Research Foundation Phase 1 report cannot happen, I have trouble understanding how the committee can justify calling the values confirmed by the simulations to be conservative.

7.13.3 CSST Spacing

CSST shall be spaced a minimum of 6 inches from any metallic component, grounded metal parts andelectrical conductors.


Field reports of CSST damage require consideration of additional protection techniques beyond lab based testing. Suitable bonding, according to other proposed sections is one method. The second is isolation to prevent arcing as proposed here. Proper separation in installation will improve survivability by protecting against arc formation, rather than depending on the CSST on its own.

Delete 7.12.3

Arc-Resistant Jacketed CSST.

CSST listed with an arc-resistant jacket or coating system in accordance with ANSI LC 1/CSA 6.26, FuelGas Piping Systems Using Corrugated Stainless Steel Tubing (CSST) , shall be electrically continuous andbonded to an effective ground fault current path. Where any CSST component of a piping system does nothave an arc-resistant jacket or coating system, the bonding requirements of 7.12.2 shall apply.Arc-resistant jacketed CSST shall be considered to be bonded when it is connected to appliances that areconnected to the appliance grounding conductor of the circuit supplying that appliance.


Requiring direct bonding of all CSST maximizes safety. The current 7.13.1 eliminates the requirement for direct bonding that will have the effect of routing lightning current through a structure maximizing the probability of arcing to/from the CSST. It also maximizes the probability of other electrical damage through other effects of the lightning current. Removing this section (7.13.1) preserves the direct bonding requirement for all CSST, maximizing safety.

The proposal to eliminate direct bonding from any CSST ignores the concept of potential equalization, which is a key feature in minimizing the likelihood of arcing. (See NFPA 780-14A, Section 4.14 – 4.14.1) Bonding through the appliance to the ground circuit is a technique that is sufficient, in many cases, of providing an effective path to ground for fault currents but not for effective potential equalization.

CSST installation techniques need to minimize development of the initial arc through potential equalization, which minimizes the severe voltage differences that can occur from lightning strikes. Bonding at the served appliance maximizes the path of lightning current through the structure (and through the CSST.) Voltage difference, leading to arcing, is proportional to distance of the circuit path.

Eliminating bonding close to the entry of the CSST to the structure actually has the effect of creating a long lightning current path through the structure which maximizes the chance of arcing somewhere within the structure. It imposes lightning current upon circuits that are not intended for lightning currents (such as gas fittings/connectors, appliance plugs, small-gauge electrical wiring, etc.) which can cause other modes of electrical damage that have not been considered. Consider also that this proposal effectively uses the CSST as a grounding conductor, which is not consistent with the intent of other parts of NFPA 54.

CSST has a resistance and inductance per unit length, as does any conductor. It is well known that voltage differences occur from current flow through a resistance and from current risetime imposed upon the inductance. Such voltage differences can far exceed test scenarios conducted for CSST.

For example, given approximately 2.5 microHenry per meter inductance of CSST (typical value from GTI, 2015) voltages induced in a 25 meter (approximately 75 feet) length are on the order of 625 kilovolts for typical (not maximal) lightning current risetimes. (Voltage equals the inductance times the risetime of the current. A realistic lightning risetime is 1010 Amperes per second. Maximal events have risetimes of 1011 Amperes per second.) Also consider the voltage induced from resistance on the current flowing through the CSST (or through any conductor) is additive, so even higher voltages are possible than demonstrated by this simple example. Development of these voltages is hazardous and well beyond the scope of CSST testing performed.

GTI and other tests show that the likelihood of CSST puncture increases as test voltage increases. (GTI 2013, 2015) Testing of CSST never occurred at values over approximately 35 kilovolts, which is far less than the possible voltage developed during realistic non-maximal lightning events, especially without any potential equalization from direct bonding. On the other hand, direct bonding is intended to minimize voltage differences between CSST and other metal structural materials and to minimize current flowing on CSST. Minimization of both substantially reduces the probability of arc development and reduces the amount of energy delivered to the CSST, should an arc occur.GTI test reports also note that lightning strikes with currents up to 50 kiloamperes occur but were not studied. (In


59 of 100 5/19/2016 9:49 AM

124

fact, lightning strikes of far greater current magnitude do occur.) Events studied by GTI were limited to 10 kiloamperes. Documentation from the committee’s formulation of this section for arc-resistant CSST notes a 400% better resistance against arcing. Yet test results used by the committee in considering other CSST proposals note 500% more current (and energy) can occur. Such events will defeat the arc-resistant CSST without some other means of defense.

I conclude that removal of the direct bonding requirement for CSST, or any metal piping system, increases the likelihood of arcing at some point of the system. Lack of direct bonding actually increases the hazard by increasing the probability of arcing as well as inducing voltages beyond the proof ratings of the arc-resistant CSST. Arc resistance of the CSST should not be relied upon as the sole defense against electrical puncture from lightning-induced arcing. Minimizing the probability of arc formation is the first line of defense. Minimizing current on the CSST, also through direct bonding is a necessary second line of defense. Arc-resistance of CSST is the last line of defense upon which there should not be sole reliance. As such, the direct bonding requirement must be retained for arc-resistant CSST to maintain a reasonable degree of safety.

This leads to confusion about what is intended. All CSST and metallic gas piping systems should be interconnected with the electrical ground at their entrance to the structure (in accordance with NEC – NFPA 70), or to the lightning protection grounding system connected to the electrical ground (in accordance with NFPA 780). Any deviation from this requirement is in violation of those standards, and good safety practice.

7.12.3 Arc-Resistant Jacketed CSST.



It would be premature for the committee to adopt this section. The language in the first draft by-passes all of the diligent research that the NFPA Research Foundation, the GTI report and repeats the error of rushing a product through the standard without getting multiple organizations and NFPA committees input. If the product has all the merits touted, then these inputs should be welcomed by the submitter. Please note that the language in the first draft is a drastic departure form proven techniques of bonding that are required in many other NFPA documents. The text should be circulated in an effort to avoid conflicting requirements among the other NFPA committees.

9.1.24* Existing Appliances.

Existing appliance installations shall be inspected to verify compliance with the provisions of Section 9.3and Chapter 12 where a component of the building envelope is modified as described by one or more of9.1.24(1) through 9.1.24(6) . Where the appliance installation does not comply with Section 9.3 andChapter 12, the installation shall be altered as necessary to be in compliance with Section 9.3 and Chapter12. The installer responsible for making the envelope component change shall be responsible forcompliance with this section.

(1) The building is modified under a weatherization program.

(2) A building permit is issued for a building addition or exterior building modification.

(3) Three or more window assemblies are replaced.

(4) Three or more storm windows are installed over existing windows.

(5) One or more exterior door and frame assemblies are replaced.

(6) A building air barrier is installed or replaced.


This addition to the Code provides requirements for a problem that has been recognized for some time, specifically changes to a building's envelope to conserve energy. Declaring that the installer is "responsible" is problematic as the installer will most likely be someone who is not a gas appliance installer, or aware of the requirements of NFPA 54. The scope of NFPA 54 states:

This code is a safety code that shall apply to the installation of fuel gas piping systems, appliances, equipment, and related accessories ...

This scope does not include installers of windows, siding, and other components used to increase building envelope tightness and is therefore unenforceable as accepted as a first revision.

9.1.24 * Existing Appliances.

Existing appliance installations shall be inspected to verify compliance with the provisions of Section 9.3and Chapter 12 where a component of the building envelope is modified as described by one or more of9.1.24(1) through 9.1.24(6) . Where the appliance installation does not comply with Section 9.3 andChapter 12, the installation shall be altered as necessary to be in compliance with Section 9.3 andChapter 12. The installer responsible for making the envelope component change shall be responsible forcompliance with this section.








This section is both problematic and vague, and should be removed. It is true that many of these actions will reduce the leakiness of the house, but that does not mean that these changes are sufficient to cause a problem with the appliance. The first trigger, "The building is modified under a weatherization program", is extremely broad. That could be anything from sealing up balloon-framing and other large bypasses to adding a door sweep. To be meaningful and relevant there needs to be some better metric indicating how much modification triggers it. As it stands, this item is actually in conflict with the third and fourth triggers. A weatherization program could modify the building by adding one storm window. So, is the action triggered because it was done by a weatherization program, or not triggered because it was only one storm window and not three?

The need for action to comply with Sections 9.3 and 12 should be based on some sort of performance testing. In other words, if the appliance fails performance testing (such as in Annex G) and the cause is the venting system itself (as opposed to such things as large return duct leakage or a bird lodged in the flue) then the remedy should be to comply with Sections 9.3 and 12, as done by a qualified technician. However, if performance testing shows that the appliance is venting satisfactorily then the process of verifying compliance with Sections 9.3 and 12 should not be required.

If this section was approved it would be problematic for some programs. Retrofit programs are generally not code compliance programs, bringing older homes up to current code. When work gets done it needs to be done to code, but if there is not a performance problem then bringing things up to current code for the sake of bringing them up to current code is not allowed. This section would be in direct conflict with these requirements.

With suitable clarifications to text such as what means a building is being modified, an alternate approach to deleting this section would be to provide an exception for appliances that passed performance testing such as Annex G of NFPA 54, ACCA 12-QH, or BPI-1200.

The language is too broad to identify where real problems may occur. The option to do the performance testing would relieve the contractor or homeowner from having to incur unnecessary extra cost. Weatherization programs already have this requirement.

The addition of the word "nominal" is added to make the code easier to use and enforce. The current text does not state if the ID or OD is to be used. Further, the nominal pipe size for 1" pipe (as an example) has an OD of 1.3 in. Therefore the nipple shown in Figure 9.6.8 must be 3.9", not 3" as a code user without a pipe size chart would reasonably use. The new requirement to provide for longer nipple lengths for larger pipe sizes is reasonable, but not support by testing, therefore using 3 times the nominal size is reasonable.

10.8.3 Installation. Direct gas-fired industrial air heaters shall be installed in accordance with themanufacturer’s instructions.

10.8.4 Clearance from Combustible Materials. Direct gas-fired industrial air heaters shall be installedwith a clearance from combustible materials of not less than that shown on the rating plate and themanufacturer’s instructions.

10.8.5 Air Supply. All outdoor air to the direct gas-fired industrial air heater shall be ducted directly fromoutdoors. Where outdoor air dampers or closing louvers are used, they shall be verified to be in the openposition prior to main burner operation.

10.8.6 Atmospheric Vents or Gas Reliefs or Bleeds. Direct gas-fired industrial air heaters with valve traincomponents equipped with atmospheric vents, gas reliefs, or bleeds shall have their vent lines, gas reliefs, orbleeds lead to a safe point outdoors. Means shall be employed on these lines to prevent water from enteringand to prevent blockage from insects and foreign matter. An atmospheric vent line shall not be required to beprovided on a valve train component equipped with a listed vent limiter.

10.8.7 Relief Openings. The design of the installation shall include adequate provisions to permit the directgas-fired industrial air heater to operate at its rated airflow without overpressurizing the space served by theheater by taking into account the structure’s designed infiltration rate, properly designed relief openings, oran interlocked powered exhaust system, or a combination of these methods.

10.8.7.1 The structure’s designed infiltration rate and the size of relief opening(s) shall be determined byapproved engineering methods.

10.8.7.2 Louver or counterbalanced gravity damper relief openings shall be permitted. Where motorizeddampers or closable louvers are used, they shall be proved to be in their open position prior to main burneroperation.

10.8.8 Purging. Inlet ducting, when used, shall be purged with at least four air changes prior to an ignitionattempt.

10.8.9 Additional Requirements for Non-Recirculating Direct gas-fired Indust rial Air Heaters

10.8.9.2 Non-recirculating direct gas-fired industrial air heaters shall be permitted to provide fresh airventilation.

10.8.9.3 Non-recirculating direct gas-fired industrial air heaters shall be provided with access for removal ofburners; for replacement of motors, controls, filters, and other working parts; and for adjustment andlubrication of parts requiring maintenance.

10.8.10 Additional Requirements for Recirculating Direct Gas-Fired Industrial Air Heaters

10.8.10.1* Recirculating direct gas-fired industrial air heaters shall not recirculate room air in buildings thatcontain flammable solids, liquids, or gases; explosive materials; or substances that can become toxic when

exposed to flame or heat.

10.8.10.2 Air to the recirculating direct gas-fired industrial air heater in excess of the minimum ventilation airspecified on the heater’s rating plate shall be taken from the building, ducted directly from outdoors, or acombination of both.


Sections 10.8 and 10.9 covering the 2 types of gas-fired industrial air heaters are repetitive, and it is recommended that they be combined to extensive delete duplication. This is believed to be reasonable as the requirements are very similar. No changes have been made to the existing requirements in this comment.

10.22.1.1 Installation in Fireplaces.

Unvented room heaters shall not be installed in factory-built fireplaces except where the factory-builtfireplace is listed for use with unvented room heaters.


The new requirement was not supported by technical data that demonstrated that installing an unvented heater in a factory-built fireplace that was not specifically listed for those heaters is a safety issue.

This proposed provision is unnecessary and inconsistent with requirements in the standards applicable to factory built fireplaces (UL127) and unvented room heaters (ANSI Z21.11.2). The issue being addressed in this proposal was first discussed within the ICC code arena in the late 1990's. At that time CSA and Underwriters Laboratories (UL) collaborated on this issue. Industry members representing listed unvented room heaters and factory-built fireplaces were invited to participate. Recognizing that all combinations of these two types of products could not be tested, CSA conducted actual fire-hazard testing on the identified worse-case fireplaces (including dome top models) and the highest temperature (primarily maximum input) unvented gas log sets. CSA did the testing with UL participation. As a result of that evaluation it was determined that the installation of gas log sets in factory built fireplaces does not present a fire hazard.

In response, the applicable standards were changed years ago to accommodate the findings. UL127 gives factory-built fireplace manufacturers the option to list their product either (a) for use with unvented gas log sets or (b) with a warning to not use unvented gas log sets. The second option permits the manufacturer to disallow the application if that is its desire. The related markings and instructions required by the standard indicate this key information to the installer. ANSI Z21.11.2 includes testing for log sets in this application. It is a absolute requirement for certification and listing of the unvented gas log sets. The markings and instructions with the logs et provide clear direction to the installer to check what is indicated on the UL127 factory-built fireplace markings and instructions to see whether or not the installation is permitted.

This situation has been in place for many years and there is no indication that it has not effectively addressed the safe and proper use of gas log sets in factory built fireplaces. The research conducted years ago showed that gas log sets can be used safely in factory built fireplaces. That is the default situation. The option in UL 127 was added to recognize that a manufacturer of factory built fireplaces may choose to not sanction the use of his products with gas log sets. But this is a choice based on personal preference, not a safety-related issue.

Currently, UL 127 requires the manufacturer's instructions for all units to include a statement as to whether or not a listed gas log set can be installed in the fireplace. For older factory built fireplaces, such a statement may not have been required. However, we are informed that in the late 1990s, testing was performed at CSA and with the involvement of Underwriters Laboratories to match worst case log sets with worst case factory built fireplaces and determine the critical temperature rises. This testing verified that in all cases, factory built fireplaces were able to accommodate the installation of listed gas log sets.

Therefore, considering this research and the fact that UL 127 now requires a declaration, the proposed text is not justified and should be stricken.

The proposal failed to obtain the number of positive votes required for acceptance. We have reviewed the negatives and responses and we believe that a compromise would better serve the involved parties and resolve the ballot comments. The compromise would be to amend the proposal to permit plastic venting to meet the appliance standards with an option to meet UL 1738. This would accomplish the following:

1. Maintain the current requirement and highlight that there is an option to use UL 1738 certified products. 2. Stakeholders can decide which standard(s) they want to use for plastic venting for the vent materials listed for use by the Appliance Manufacturer.3. Address the comments related to the conflict created by mandating UL 1738 as the only alternative.

Public comment on NFPA 54

From: Larry Gill and Gaetano Altomare – IPEX USA LLC

Background

A proposal to mandate that plastic venting be certified to UL 1738 - Standard for Safety – Venting

Systems for Gas-Burning Appliances Categories II, III, and IV was considered by the NFPA committee

(see attachment 1 at the end of this document). The proposal failed to obtain the number of positive

votes required for acceptance. We have reviewed the negatives and responses and we believe that a

compromise would better serve the involved parties and resolve the ballot comments. The compromise

would be to amend the proposal to permit plastic venting to meet the appliance standards with an

option to meet UL 1738. This would accomplish the following:

1. Maintain the current requirement and highlight that there is an option to use UL 1738 certified

products.

2. Stakeholders can decide which standard(s) they want to use for plastic venting for the vent

materials listed for use by the Appliance Manufacturer.

3. Address the comments related to the conflict created by mandating UL 1738 as the only

alternative.

In addition to this proposed Code change we will undertake to propose revisions to the appliance

standards to recognise UL 1738 as a standard for venting. Note that this code change does not rely on

concurrent changes to the appliance standards. Currently the appliance standards only mandate that a

material (PVC for example) with a specific Heat Deflection Temperature (HDT) be used. The appliance

standards reference certain ASTM and CSA plastics standards but they do not mandate that the vent

product be listed or labeled to these ASTM and CSA standards.

The Proposal


Where plastic piping is used to vent an appliance, the appliance shall be listed for use with such venting

materials and the appliance manufacturer's installation instructions shall identify the specific plastic

piping material. The plastic pipe venting materials shall be labeled in accordance with the product

standards specified by the appliance manufacturer or shall be listed and labeled in accordance with UL

1738.

12.5.3 Plastic Vent Joints.

Plastic pipe and fittings used to vent appliances shall be installed in accordance with the appliance

manufacturers and the vent manufacturers’ installation instructions if available. Where primer is

required, it shall be of a contrasting color.

154

Rationale

Currently in the United States plastic flue gas venting is required to meet the appliance standards. The

appliance standards mandate that plastic vent materials be tested with the appliance for various

scenarios. The temperature of the plastic vent is measured at defined locations with a requirement that

the temperature cannot exceed the HDT for the plastic in question (PVC, ABS and CPVC). This system of

plastic venting has been in use successfully for many years.

Recently the appliance standards were revised to exclude Cell core PVC and ABS due to concerns with

the thin outside layer deteriorating when assembled. In Canada there were incidents involving ABS

which prompted ULC S636 to be mandated in the B149 gas Code in 2007. Further, in Canada ABS is no

longer permitted as a venting material. ULC S636 has some similarities to UL 1738 but the standards are

different. In the United States it appears that there have been reported appliance venting related

incidents but details are lacking other than for a handful of incidents.

Clearly there have been some venting “issues” and the industry has reacted with changes to the

appliance standards and the Gas Code in Canada. Even if all parties cannot agree that there is a problem

that needs to be corrected we should be able to agree that an alternative to the current offering is a

reasonable step.

There have been ongoing discussions amongst the appliance manufacturers, vent manufacturers and

the NPFA 54 Code regarding the installation of non-metallic venting systems with no resolution. The

purpose of this change is to attempt resolution by maintaining the current requirements while

highlighting the option of using UL 1738. This will allow all parties to be able to specify and install what

they and their customers want. This proposal does not raise any concerns with the existing ASTM and

CSA appliance referenced standards.

This proposal is intended to provide options for manufacturers, users and regulators. If approved it

would permit venting to meet the requirements of the appliance standards (ASTM and CSA referenced

standards for venting), with the option to meet UL 1738.

The revision would require all plastic materials used to vent Category II, III, and IV appliances to meet UL 1738. Thischange would place the code in direct conflict with several ANSI safety standards for gas appliances, such as forwater heaters (ANSI Z21.10.1 and Z21.10.3), boilers (ANSI Z21.13), and central furnaces (ANSI Z21.47). Thesestandards for years have allowed for the use of PVC and CPVC materials for use in venting condensing gasappliances, when certain testing and performance conditions are met. This ensures that the safe performance of suchmaterials is met when certifying a specific appliance design for use with plastic materials. In addition, the water heaterand boiler standards have updated their coverage to prohibit the use of cellular core PVC and CPVC. This codeproposal would not only require manufacturers of certified appliances to search for UL 1738 listed plastic ventingsystems, but it would place in doubt those plastic venting systems that have been certified as part of a listed appliancewith proven safe performance in the field for many years. It is not known if any PVC or CPVC plastic venting systemsexist on the market that are listed to UL 1738. Testing a plastic venting system separate from the appliance does notensure that the vent system will be appropriate for a specific appliance. The UL 1738 standard makes assumptionsabout the volume and flow of flue gas for the test that in some cases are lower than the actual appliance wouldproduce. The amount of volume and velocity of flue gas will impact the vent pipe wall temperatures that the ventstandard does not replicate for a specific appliance design. There have been efforts made in the past to correlate thevent standard performance test to that of the appliance standard tests for plastic venting systems but this work has notresulted in adequate coverage for the venting standard. Until this is demonstrated and proven to be at least equal tothe appliance standards’ coverage it would be premature to require such a change to the NFGC.

Coates, Sharon E.

The proposal would require a retrofit of all venting systems currently in use and compliance with codes as installedand this proposal would create an unnecessary hardship to retro-fit all systems and maybe not be the safest solution. Ifeel sufficient evidence to require this change was not present.

The revision would require all plastic piping used to vent Category II, III, and IV appliances to meet the UL 1738. PVCventing materials are currently permitted by the NFGC and the applicable appliance standards. The appliance is testedand certified with the venting systems. The proposed revision to require all plastic venting systems to be listed to UL1783 would create a conflict between the code and appliance standards and manufacturer’s instructions. The publicinput did not provide evidence that a widespread safety issue exists. Nor was any evidence provided that documents adeficiency in the ANSI appliance standards, which require the plastic pipe chosen by the appliance manufacture betested and listed for use with that appliance.

Davis, Gerald G.

This revision would cause a conflict with the current appliance listing for condensing furnaces. The appliance listingallows PVC piping to be used to vent the equipment.

Deegan, Mike

Specifically reviewing the proposal requirement that the use of PVC for venting of category II, III and IV appliances belisted to the UL 1738 standard. Currently the manufacturers of these condensing appliances allow the use of PVC forthe venting of these appliances. This requirement would conflict the manufacturer's design and installation instructions.Additionally no substantiation has been provided that a deficiency exists in the current ANSI standards which requirethe plastic pipe chosen by the appliance manufacture be tested and listed for use with that appliance.

Gorham, Mike

The public input did not establish that any significant safety problem exists. Appliance manufacturers haverecommended non-listed PVC for years and are apparently content to continue to do so. This is a non-problem.

Lemoff, Theodore C.

1. The committee statement that the revision will require all venting products to be listed is not correct. Single WallMetal Pipe is not required to be listed. 2. The format of Table 12.5.1 is changed by deleting "As specified or furnished

by manufacturers of listed appliances" with no replacement. A statement should be provided to guide the user, ratherthan have this table serve as an index. 3. No substantiation is provided by the committee to support the newrequirement that plastic gas vents be listed. These product have been in use for at least 20 years. If failures haveoccurred they should have been reported to the committee. In PI 135 the substantiation points to the advantages oflisting plastic venting products to UL 1738, but does not provide any reason that the existing products are notadequate, rather it states that the testing in UL 1738 is more thorough than the current ASTM standards. If listing ofplastic vent products is to be made mandatory, it should be based on technical substantiation that unlisted productsare not working, not that one standard is better than another.

Osterhaus, James T.

Agree with the comments made by those voting in the initial ballot against the proposed revision.

Papageorge, Andrea Lanier

The proposed amendments would require that plastic pipe meet UL 1738 when used to vent category II, III, and IVappliances. PVC, which is currently permitted for use by manufacturers for venting of condensing appliances, is notlisted by UL 1738. There was not sufficient evidence presented to require this change.

Swim, Peter C.

The proposed revision would create a conflict between the code and appliance standards and manufacturer’sinstructions. The public input did not indicate that a safety issue exists.

12.5.4 Special Gas Vents.

Special gas vents shall be listed and labeled in accordance with ANSI/UL 1738, Venting Systems forGas-Burning Appliances, Categories II, III, and IV , and installed in accordance with the special gas ventmanufacturer's installation instructions.


Two methods are appropriate for venting Categories II, III, and IV appliances – (1) As specified or furnished by manufacturers of listed appliances or (2) listed special gas vents. In the current code language, Table 12.5.1 already recognizes the second method by referencing Section 12.5.4. Also, listed special gas vents are already recognized in the current code for other types of appliances in Table 12.5.1. Section 12.5.4 already requires special gas vents to be listed. ANSI/UL 1738 is the standard for listing special gas vents.

Public Comment No. 75-NFPA 54-2016 [ Section No. A.5.6.6.4 ]

A.5.6.6.4

Joint sealing compounds are used in tapered pipe thread joints to provide lubrication to the joint as it istightened so that less tightening torque is “used up” to overcome friction and also to provide a seal of thesmall leak paths that would otherwise remain in a metal-to-metal threaded joint.

Commonly used joint sealing compounds include pipe dope and polytetrafluoroethylene tape, also known

as PTFE or Teflon® tape. Some pipe dopes also contain PTFE. Joint sealing compounds should be appliedso that no sealing compound finds its way into the interior of a completed joint.

Pipe dope application should be made only to the male pipe thread of the joint and should coat all of thethreads commencing one thread back from the end of the threaded pipe.

PTFE tape application should be made by wrapping the tape tightly around the male thread in a clockwisedirection when viewed from the end of the pipe to which the tape is being applied. Tape application shouldwrap all of the threads commencing one thread back from the end of the threaded pipe.

One method to use for sealing is pipe joint sealing compounds listed in accordance with UL 1356, Outlineof Investigation of Pipe Joint Sealing Compounds, which a re suitable for use in joining threaded metalpipe connections in devices handling fluids to assist in rendering joints tight against leakage, when thecompound is identified for use with natural gas.

One method to use for sealing is pipe tape listed in accordance with UL 1321, Outline of Investigation forPolytetrafluoroethylene Plastic Seal Materials, which are intended for application in accordance with themanufacturer's instructions to male threads of metal pipe in devices handling fluids to assist in renderingjoints tight against leakage.


The proposal does not require the use of only listed pipe sealing materials. This proposal is simply recognizing that pipe sealing materials that are listed to UL 1321 or UL 1356 are considered suitable for rendering pipe joints tight against leakage. The proposal has been revised to clarify there are other methods. The purpose of Annex A is to provide explanatory material for informational purpose only. This proposal assists the user of NFPA 54 to identify those listed pipe sealing joint compounds and tapes that are considered as suitable for installation in accordance with NFPA 54.

Public Comment No. 83-NFPA 54-2016 [ New Section after A.7.12.2 ]

Arcing to/from CSST to metal components, grounded metal parts or electrical conductors canoccur under lightning strike conditions near a

structure. Spacing, in addition to bonding, further minimizes development of arcs. Arcing is morelikely to occur if CSST is in contact with, or close proximity

to, metal parts including structural components, other pipe/duct systems, electrical serviceconductors and data conductors. Spacing CSST from metal

structural components, other piping systems (such as water piping, HVAC ducting, electricalequipment, etc.) and electrical conductors minimizes the

possibility of the development of an arc.


Addition of this section provides informational detail on spacing of CSST from metal parts for arc avoidance.

Spacing of CSST from metallic objects is recommended by manufacturers and local codes to prevent electrical arcing to CSST from lightning strikes and/or otherelectrical transients. No enforceable/inspectable language exists to consistently articulate this requirement. This input in annex provide additional information withregard to a proposed normative input, PI# 110 and Comment #81.

Adding spacing to CSST installations is justified by empirical observations, test results, physics of arc development and precedent set by some local codes as well asmanufacturer instructions.

Forensic review of CSST puncture as a consequence of near-strike lightning reveals that in many cases an arc develops to or from a metallic component in closeproximity, despite the presence of direct bonding of the CSST to ground electrode system, as required by NFPA 54 and many manufacturers.Review of recent reports and studies, notably the GTI report on the matter, (Validation of Installation Methods for CSST Gas Piping to Mitigate Indirect LightningRelated Damage, September 5, 2013 available on nfpa.org) shows that arcs can develop despite the presence of bonding. Depending on certain variables includingthe length of the bonding conductor and magnitude of the lightning event, arcs may or may not cause damage. Spacing minimizes the possibility of arcing thus furtherminimizing the possibility of damage to the CSST.

While the insulating coating (intended to enhance safety to defeat lightning-related arcing) on the CSST for most manufacturers has a dielectric strength ofapproximately 60 kilovolts, on average, it is not sufficient to guard against the voltages that could be developed in a near-strike lightning event. Addition of the 6-inchspacing provides an additional 450 kilovolt isolation, approximately. In fact, some recent publications suggest that the insulating coating is not effective in minimizingarcing and the actual dielectric strength of the CSST as installed is significantly lower than 60 kilovolts. (Goodson, Icove, ISFI 2014, accessed at:http://goodsonengineering.com/wp-content/uploads/Electrical-Characterization-of-CSST.pdf) Adding the spacing enhances protection by defeating any dielectricstrength reductions imposed by bends in the CSST, damage or irregularity in the coating, dirt on the coating, etc.

As a precedent, some local codes have adopted spacing as a requirement. The most common language used in these codes say to “maintain as much separation asreasonably possible from other electrically conductive systems in the building.” Sample codes were provided with PI #111.

A.7.12.2

The required bonding connection may be made from the piping to the electrical service equipmentenclosure, to the grounded conductor at the electrical service, to the grounding electrode conductor (whereof sufficient size), or directly to the grounding electrode. The bond may also be made to a lightningprotection system grounding electrode (but not to down conductors) if the resulting length of the bondingconductor is shorter. Lightning protection grounding systems are bonded to the electrical service groundingelectrodes, in accordance with NFPA 780, using a method to minimize impedance between the systems.

Listed clamps are manufactured to facilitate attachment of the bonding conductor to either a segment ofrigid pipe or to a CSST-copper alloy fitting. Clamps should be installed to remain accessible when buildingconstruction is complete.

The maximum length of the bonding connection was established based on studies conducted by the GasTechnology Institute in Project Number 21323, Validation of Installation Methods for CSST Gas Piping toMitigate Indirect Lightning Related Damage. The shortest practical length should always be used. Stateand local laws can limit who can attach the bonding connection to the building grounding system.

The size of the bonding conductor, a 6 AWG copper wire, is a minimum size, and larger wire can be used.The requirement also permits conductors of different materials (of equivalent size) and both single wire andmulti-strand.

A.7.12.2.3

If the bonding jumper required would be longer than 75 ft, an additional grounding electrode can beinstalled to allow a bonding jumper that is 75 ft or less. The maximum length of the bonding connection wasestablished based on studies conducted by the Gas Technology Institute in Project Number 21323 report,"Validation of Installation Methods for CSST Gas Piping to Mitigate Indirect Lightning Releated Damage." Simulations provided in the GTI report show the benefit of providing grounding of incoming servicesat each service entry. The simulations also calculate acceptable bonding cable lengths for additionalbonds involving CSST installation scenarios. The simulations confirm the shorter the bonding cable themore effective the bond. Efforts should be made to keep the bonding conductors as short as reasonable. Bonding distances of 25 feet or less are preferred. The installation of additional bonds and groundingelectrodes are acceptable as long as these additional grounding electrodes are interconnected with eitherlightning protection system grounding electrodes (where provided) or electrical service groundingelectrodes.


The proposed revision consolidates the annex discussion on bonding conductor length to the clause in which it is discussed in the normative section (7.12.2.3). The proposed revision incorporates the intent of PI-163 and PI-165, maintains the reference to the GTI report, makes it clear that the simulations in the GTI report all incorporate an current division at all service entry points, and maintains the existing recommendation that bonding conductors should be kept as short as practicable.

C.3 Leak Check Not Using a Meter.

This test can be done using one of the following methods:

(1) For Any Gas System.

(a) To an appropriate checkpoint, attach a manometer or pressure gauge between the inlet to thepiping system and the first regulator in the piping system, momentarily turn on the gas supply,and observe the gauging device for pressure drop with the gas supply shut off. No discernibledrop in pressure should occur during a period of 3 minutes.

(b) Attach an in-line flow meter between the meter outlet and piping system inlet prior to the firstregulator in the piping system. Slowly turn on the gas supply and observe the metering device. Ifflow does not drop to zero, leakage is indicated.

(2) For Gas Systems Using Undiluted LP-Gas System Preparation for Propane. A leak check performedon an LP-Gas system being placed back in service can be performed by using one of the followingmethods:

(3) Insert a pressure gauge between the container gas shutoff valve and the first-stage regulatoror integral two-stage regulator in the system, admitting full container pressure to the system andthen closing the container shutoff valve. Enough gas should then be released from the system tolower the pressure gauge reading by 10 psi (69 kPa). The system should then be allowed tostand for 3 minutes without showing an increase or a decrease in the pressure gauge reading.

(4) Insert a gauge/regulator test assembly between the container gas shutoff valve and first-stageregulator or integral two-stage regulator in the system. If a gauge/regulator test assembly with aninches water column gauge is inserted, follow the test requirements in C.3(2)(c) ; if agauge/regulator test assembly with a 30 psi gauge is inserted, follow the test requirements inC.3(2)(d) .

(5) For systems with an integral two-stage, one or more second-stage, or one or more line

pressure regulators serving appliances that receive gas at pressures of 1 ⁄ 2 psi (3.5 kPa) orless, insert a water manometer or inches water column gauge into the system downstream ofthe final stage regulator, pressurizing the system with either fuel gas or air to a test pressure of 9

in. w.c. ± 1 ⁄ 2 in. w.c. (2.2 kPa ± 0.1 kPa), and observing the device for a pressure change. Iffuel gas is used as a pressure source, it is necessary to pressurize the system to full operatingpressure, close the container service valve, and then release enough gas from the systemthrough a range burner valve or other suitable means to drop the system pressure to 9 in. w.c. ±1 ⁄ 2 in. w.c. (2.2 kPa ± 0.1 kPa). This ensures that all regulators in the system upstream of thetest point are unlocked and that a leak anywhere in the system is communicated to the gaugingdevice. The gauging device should indicate no loss or gain of pressure for a period of 3 minutes.

(6) When testing a system that has a first-stage regulator, or an integral two-stage regulator, inserta 30 psi (207 kPa) pressure gauge on the downstream side of the first-stage regulator or at theintermediate pressure tap of an integral two-stage regulator, admitting normal operating pressureto the system and then closing the container valve. Enough gas should be released from thesystem to lower the pressure gauge reading by a minimum of 2 psi (13.8 kPa) so that thefirst-stage regulator is unlocked. The system should be allowed to stand for 3 minutes withoutshowing an increase or a decrease in pressure gauge reading.

(7) Insert a gauge/regulator test assembly on the downstream side of the first stage regulator or atthe intermediate pressure tap of an integral two stage regulator. If a gauge/regulator testassembly with an inches water column gauge is inserted, follow the test requirements inC.3(2)(c) ; if a gauge/regulator test assembly with a 30 psi gauge is inserted, follow the testrequirements in C.3(2)(d) .

The proposal does not require the use of only listed pipe sealing materials. This proposal is simply recognizing that pipe sealing materials that are listed to UL 1321 or UL 1356 are considered suitable for rendering pipe joints tight against leakage. The proposal has been revised to clarify there are other methods. The purpose of Annex A is to provide explanatory material for informational purpose only. This proposal assists the user of NFPA 54 to identify those listed pipe sealing joint compounds and tapes that are considered as suitable for installation in accordance with NFPA 54.
