AIR FORCOMBUSTION ANDVENTILATION

Today’s homes are built more energy effi-cient than ever. New materials, increasedinsulation, and new construction methodshelp reduce heat loss in homes. Home ownersweather strip and caulk around windows anddoors to keep the cold air out and the warm airin. During heating months, home ownerswant their homes as airtight as possible.

While it is good to make your home energyefficient, your home needs to breathe. Freshair must enter your home. All fuel-burningappliances need fresh air for proper com-bustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, andfuel burning appliances draw air from thehouse to operate. You must provide ad-equate fresh air for these appliances. Thiswill insure proper venting of vented fuel-burning appliances.

Confined and Unconfined Space

The National Fuel Gas Code ANS Z223.1defines a confined space as a space whosevolume is less than 50 cubic feet per 1,000Btu per hour (4.8 m3 per kw) of the aggre-gate input rating of all appliances installedin that space and an unconfined space as aspace whose volume is not less than 50cubic feet per 1,000 Btu per hour (4.8 m3 perkw) of the aggregate input rating of allappliances installed in that space. Roomscommunicating directly with the space inwhich the appliances are installed*, throughopenings not furnished with doors, are con-sidered a part of the unconfined space.

This heater shall not be installed in a con-fined space or unusually tight constructionunless provisions are provided for adequatecombustion and ventilation air.

* Adjoining rooms are communicating onlyif there are doorless passageways or ventila-tion grills between them.

PROVIDING ADEQUATEVENTILATIONThe following are excerpts from NationalFuel Gas Code. NFPA 54/ANS Z223.1, Sec-tion 5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the threefollowing ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 4 through 6 willhelp you classify your space and provideadequate ventilation.

Unusually Tight Construction

The air that leaks around doors and win-dows may provide enough fresh air forcombustion and ventilation. However, inbuildings of unusually tight construction,you must provide additional fresh air.

Unusually tight construction is de-fined as construction where:a. walls and ceilings exposed to the

outside atmosphere have a con-tinuous water vapor retarder witha rating of one perm (6 x 10 -11 kgper pa-sec-m 2) or less with open-ings gasketed or sealed and

b. weather stripping has beenadded on openable windows anddoors and

c. caulking or sealants are appliedto areas such as joints aroundwindow and door frames, be-tween sole plates and floors, be-tween wall-ceiling joints, be-tween wall panels, at penetra-tions for plumbing, electrical, andgas lines, and at other openings.

If your home meets all of the threecriteria above, you must provide ad-ditional fresh air. See Ventilation AirFrom Outdoors , page 6 .

If your home does not meet all of thethree criteria above, proceed to De-termining Fresh-Air Flow For HeaterLocation, page 5.

WARNING: This heater shallnot be installed in a confined spaceor unusually tight constructionunless provisions are providedfor adequate combustion and ven-tilation air. Read the following in-structions to insure proper freshair for this and other fuel-burningappliances in your home.

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION

Determining if You Have a Confined or Unconfined Space

Use this worksheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills betweenthe rooms.

1. Determine the volume of the space (length x width x height).

Length x Width x Height = _________________cu. ft. (volume of space)

Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) =2560 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume ofthe space.

2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.

_________________ (volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)

Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free heater ___________________Btu/Hr

Gas water heater* ___________________Btu/Hr

Gas furnace ___________________Btu/Hr

Vented gas heater ___________________Btu/Hr

Gas fireplace logs ___________________Btu/Hr

Other gas appliances*+ __________________Btu/Hr

Total = __________________Btu/Hr

* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

_________________ Btu/Hr (maximum the space can support)

_________________ Btu/Hr (actual amount of Btu/Hr used)

Example: 51,200 Btu/Hr (maximum the space can support)

60,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.You must provide additional fresh air. Your options are as follows:

A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin-ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 6.

C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need noadditional fresh air ventilation.

Example:Gas water heater 40,000 Btu/Hr

Vent-free heater + 20,000 Btu/Hr

Total = 60,000 Btu/Hr

Continued

WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined spaceor if the building is of unusually tight construction, provide adequate combustion and ventilation air by one ofthe methods described in the National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicable local codes .

CONNECTING TO GASSUPPLY

The installer must supply an external regu-lator. The external regulator will reduceincoming gas pressure. You must reduceincoming gas pressure to between 11 and 14inches of water. If you do not reduce incom-ing gas pressure, heater regulator damagecould occur. Install external regulator withthe vent pointing down as shown in Figure13. Pointing the vent down protects it fromfreezing rain or sleet.

WARNING: A qualified serviceperson must connect heater to gassupply. Follow all local codes.

Shutting Off Heater1. Turn control knob clockwise

Clockwise to the OFF position.2. Turn off all electric power to the ap-

pliance if service is to be performed.

Shutting Off Burner Only (pilotstays lit)

Turn control knob clockwise Clockwise tothe PILOT position.

THERMOSTATCONTROL

OPERATIONThe thermostatic control used on thesemodels differs from standard thermo-stats. Standard thermostats simply turnon and off the burner. The thermostatused on this heater senses the room tem-perature. The thermostat adjusts theamount of gas flow to the burner. Thisincreases or decreases the burner flameheight. At times the room may exceed theset temperature. If so, the burner willshut off. The burner will cycle back onwhen room temperature drops below theset temperature. The control knob can beset to any heat level between HI and LO.

Note: The thermostat sensing bulb mea-sures the temperature of air near theheater cabinet. This may not always agreewith room temperature (depending onhousing construction, installation loca-tion, room size, open air temperatures,etc.). Frequent use of your heater will letyou determine your own comfort levels.

MANUAL LIGHTINGPROCEDURE

1. Remove front panel (see Figure 7,page 8).

2. Follow steps 1 through 5 under Light-ing Instructions.

3. With control knob pressed in, strikematch. Hold match to pilot until pi-lot lights.

4. Keep control knob pressed in for 30seconds after lighting pilot. After 30seconds, release control knob. Nowfollow step 8, column 2.

CLEANING BURNERPILOT AIR INLET HOLEWe recommend that you clean the unit ev-ery 2,500 hours of operation or every threemonths.

We also recommend that you keep the burnertube and pilot assembly clean and free of dustand dirt. To clean these parts we recommendusing compressed air no greater than 30 PSI.Your local computer store, hardware store, orhome center may carry compressed air in acan. You can use a vacuum cleaner in theblow position. If using compressed air in acan, please follow the directions on the can.If you don't follow directions on the can, youcould damage the pilot assembly.

1. Shut off the unit, including the pilot.Allow the unit to cool for at least thirtyminutes.

2. Inspect burner, pilot for dust and dirt.

3. Blow air through the ports/slots andholes in the burner.

Clean the pilot assembly also. A yellow tip onthe pilot flame indicates dust and dirt in the pilotassembly. There is a small pilot air inlet holeabout two inches from where the pilot flamecomes out of the pilot assembly (see Figure 23).With the unit off, lightly blow air through the airinlet hole. You may blow through a drinkingstraw if compressed air is not available.
