Damper Troubleshooting

The following is a possible cause and correction list for common concerns with the dampers.

Symptom Possible Cause Corrective Action

Damper does not fully open and/or close

Frame is 'racked' causing blades to bind on jamb seals

Adjust frame such that it is square and plumb

Actuator linkage loose Close damper, disconnect power, adjust and tighten linkage

Defective motor Replace

Screws in damper linkage Damper installed too far into wall. Move out to line as designated on damper label

Contaminants on damper Clean with a non-oil based solvent (see Damper Maintenance)

RRL or TOR sensor tripped

Heat Push reset button located on backside of RRL or TOR

Damper does not operate

No power supplied to the actuator Add power supply

Damper MaintenanceDampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use mild detergents or solvents. If lubrication is desired for components such as axle bearings, jackshaft bearings and jamb seals, do not use oil-based lubricants or any other lubricants that attract contaminants such as dust.

Dampers and their actuator(s) must be maintained, cycled, and tested a minimum in accordance with:

• The latest editions of NFPA 80, 90A, 92A, 92B, 101, 105, UL864, AMCA 503-03 and local codes.

• Actuator manufacturer recommendations.

Pre-Installation GuidelinesThe basic intent of a proper installation is to secure the fire or fire smoke damper in, not to, the opening in such a manner as to prevent distortion and disruption of damper operation. This is accomplished by allowing the fire or fire smoke damper in rated separation openings to expand and for the connecting duct to separate in the event of the collapse of the hanging system. The following items will aid in completing the damper installation in a timely and effective manner.

1) Check the schedules for proper damper locationswithin the building. Visually inspect the damper fordamage and verify that the Reusable Resettable Link(RRL) is in place or has not activated. Never install afire damper without the proper UL approved RRL inplace. (RRL is standard control option. These electriclinks have a button for resetting.) If damper is furnishedwith fusible link, visually inspect the link to verify its notmissing or broken. Replace link as necessary.

2) Lift or handle damper using sleeve or frame. Do not liftdamper using blades or actuators.

3) Damper has label on outside of sleeve indicating a‘No Screw’ area. Do not install screws into this area asscrews may interfere with unexposed blade linkage andprevent damper blades from opening and/or closing.

4) Damper has label indicating position of damperand sleeve assembly in the wall. Install accordinglyto comply with manufacturer’s appropriate ULClassification file number.

5) Damper must be installed into duct or opening squareand free of twist or other misalignment. Damper mustnot be squeezed or stretched into duct or opening. Outof square, racked, twisted or misaligned installationscan cause excessive leakage and/or torque

requirements to exceed damper/actuator design.

6) Damper and actuator must be kept clean andprotected from dirt, dust and other foreign materialsprior to and after installation. Examples of such foreignmaterials include but are not limited to:

a) Mortar dustb) Drywall dustc) Firesafing materialsd) Wall texturee) Paint overspray

7) Damper should be sufficiently covered as to preventoverspray if wall texturing or spray painting will beperformed within 5 feet of the damper. Excessive dirtor foreign material deposits on damper can causeexcessive leakage and/or torque requirements toexceed damper/actuator design.

8) Caulking is not necessary, nor is it allowed, betweenthe damper sleeve and the wall or floor opening(annular space). However, caulking may be applied tothe retaining angles.

9) ACCESS: Suitable access (such that RRL’s andactuators can be maintained, etc.) must be providedfor damper inspection and servicing. Where it is notpossible to achieve sufficient size access, it will benecessary to install a removable section of duct. (Referto NFPA 90A).

10) The Code Authority Having Jurisdiction (AHJ) mustevaluate and provide approval of final installationwhere variations to these instructions are necessary.


Important!Electrical input may be needed for this equipment. This work should be performed by a qualified electrician. Verify power before wiring actuator. Greenheck is not responsible for any damage to, or failure of the unit caused by incorrect field wiring. To avoid causing death or serious bodily harm to building occupants, follow all instructions carefully. Dampers must close completely to preserve the integrity of the fire smoke separation.

1. CLEARANCES REQUIRED BETWEEN FIRE DAMPERSLEEVES AND WALL/FLOOR OPENINGS Fire damper and sleeve assemblies expand during periodsof intense heat. Therefore, it is essential that openings inwalls or floors be larger than the fire/smoke damper andsleeve assembly to allow for this expansion. Minimumclearances required between the outside of fire dampersleeve assemblies and wall/floor openings are:

• Galvanized steel fire dampers and sleeves: 1⁄8 in. perfoot (3mm per .3 m) of damper width and 1⁄8 in. per foot(3mm per .3 m) height with a minimum clearance of 1⁄4 in.(6mm), maximum of 1 1⁄2 in. (38mm).

Recommended clearances, for width and/or height dimensions of: 1) 48 in. (1219mm) or less: 1⁄2 in. (13mm) clearance

2) More than 48 in. (1219mm) and 96 in. (2438mm) orless: 1 in. (25mm) clearance

3) More than 96 in. (2438mm): 11⁄2 in. (38mm) clearance

• Stainless steel fire/smoke dampers and stainless steelor galvanized sleeves: 3⁄16 in. per foot (5mm per .3 m) ofdamper width and height with a minimum clearance of1/4 in. (6mm), maximum of 2 in. (51mm).

Recommended clearances, for width and/or height dimensions of: 1) 48 in. (1219mm) or less: 3⁄4 in. (19mm) clearance.

These are total clearances (ignoring fastener heads) and do not need to be equally spaced around the damper. Refer to Section 4 and Figure 6 for additional installation considerations.

Example: A 12 in. x 12 in. (305mm x 305mm) will require a minimum clearance of 1/4 in. (6mm) width and 1/4 in. (6mm) on height

A 36 in. x 12 in. (914mm x 305mm) damper will required a minimum clearance of 1/2 in. (13mm) on width and 1/4 in. (13mm) on height.

2. SLEEVE LENGTH AND WALL THICKNESSInsert the sleeved damper assembly into the prepared opening, to appropriate depth (refer to label on outside of sleeve for location of damper in wall; see Page 3, Dimension A and Detail 1, Fig. 1).

Recommended maximum and minimum insertion depth can be exceeded if:

1) The operation of the damper is not impeded and2) The CL of the damper frame remains within the plane

of the wall and3) Attachments made through the retaining angle do not

penetrate the ‘No Screw’ area designated on thedamper sleeve.

See page 7 for additional information on breakaway sleeve connections.Sleeve thickness must not be less than the gauge of the connecting duct.UL Standard 555 requires all ducts to terminate at fire damper sleeves.

4. SECURING THE DAMPER/SLEEVE ASSEMBLY TOWALL AND FLOOR OPENINGS (for single side retainingangle instructions, see supplements) Damper/sleeve assemblies must be installed in wall andfloor openings using retaining angles on at least one sideof the wall or floor as described below:

• Retaining angles for 11/2 hour rated dampers with awidth and height 48 in. (1219mm) or less must be aminimum of 20 ga. (1mm). Retaining angles for all 3 hourrated dampers and all dampers with a width or heightgreater than 48 in. (1219mm) must be a minimum of 16gauge (1.5mm). The leg of the retaining angle on thedamper sleeve shall be a minimum of 11/4 in. (32mm).The leg of the retaining angle on the wall/floor shall belong enough to cover the annular space and overlap thewall/floor by a minimum of 1 in. (25mm).

• Retaining angles must be attached to the damper usingone or more of the following methods of attachment(refer to label on outside of sleeve for ‘No Screw’ area):

• Tack or spot welds• #10 (3/4 in. [19mm] max.) sheet metal screws• 1/4 in. (6mm) bolts and nuts• 3/16 in. (5mm) steel pop rivets

A minimum of two connections per side, top, and bottom, 12 in. (305mm) O.C. maximum for openings of 48 in. W x 36 in. H (1219mm x 914mm) and less, and 6 in. (152mm) O.C. for openings 80 in. W x 50 in. H (2032mm x 1270mm), 50 in. W x 72 in. H (1270mm x 1829mm), and 40 in. W x 72 in. H (1016mm x 1829mm) or less. The angles must be attached to all 4 sides of the sleeve. Ensure that attachment device does not interfere with the operation of the damper and the free movement of the damper blades. The angles need not be attached to each other at the corners. Do not secure the retaining angle to the fire separation (see Fig. 3).

• Retaining angles should not be fastened to the wall/floor material. The angles should only sandwich thewall/floor and allow for damper expansion duringperiods of intense heat.

IMPORTANT SAFETY DANGER! : To avoid causing death or serious bodily harm to building occupants, do not penetrate the ‘No Screw’ area designated on the damper sleeve or the damper may not close properly.

The sleeve may extend a maximum of 16 in. (406mm) beyond the wall or floor on the actuator side of the damper and a maximum of 6 in. on the opposite side. Recommended standard sleeve lengths for various wall thicknesses are:

6. INSTALLING MULTIPLE DAMPER SECTIONASSEMBLIESA damper assembly is not restricted to a maximumnumber of sections, but must not exceed the sectionsizes and overall sizes shown (see chart).

Two section high dampers require reinforcement using a14 gauge (2mm), 5 in. (127mm) wide mullion as shown inFig. 4 below, or two individually sleeved units stackedvertically, shown below in Fig. 5. When using twoindividually sleeved units, the sleeve acts as the mullion,therefore no mullion is required.

The damper sections must be attached together with#10 (3/4 in. max. [19mm]) sheet metal screws, 1/4 in. (6mm)diameter nuts and bolts, tack or spot welds, or 3/16 in.(48mm) diameter steel pop rivets. Attachments must bespaced a maximum of 6 in. (152mm) on centers and amaximum of 2 in. (51mm) from corners. Attachments mustbe made on front face and back face (air entering and airexiting side) of damper sections.

Note: Dampers ordered for individual installation maynot be installed together. The full assembly size must bespecified at the time the dampers are ordered.

7. CONNECTION AND OPERATION OF TEMPERATURERESPONSE DEVICES (RRL STANDARD, OCI OPTION,AND TOR OPTION) RRL - Dampers will be supplied with a thermostat-typetemperature response device, as a standard. The deviceis a RRL (resettable link device), which only incorporatesone thermostat and therefore the damper remainsclosed as soon as its sensor temperature is reached.The RRL does not contain blade indication switches.Refer to Fig. 6 for wiring of the RRL thermostat.

OCI - The OCI (open or closed indicator) option contains a single pole, double throw switch used to indicate the damper blade position. The switch provides a positive open or closed signal when used in conjunction with remote indicator lights. Refer to Fig. 7 & 8 for wiring of the OCI option.

TOR - The TOR (temperature override device) option incorporates two thermostats with fixed settings (usually 165°F [74°C] and 350°F [177°C]). The primary sensor (the sensor with the lower temperature setting) can be bypassed by an external electrical signal allowing the damper to reopen until the temperature reaches the setting of the secondary sensor (the sensor with the higher temperature setting). See Fig. 8.

When the temperature of the secondary sensor is exceeded the damper closes and remains closed thereafter.

The TOR assembly also contains a single pole, double throw switch used to indicate damper blade position. The switch provides a positive open or closed signal when used in conjunction with remote indicator lights. See Fig. 8 for wiring of the TOR thermostats and indicator switches.

If either the TOR or the RRL is ordered with a pneumatic actuator, an EP switch is required with an appropriate electric power circuit to allow the electric thermostat to control the pneumatic actuator.

PRV - The PRV (pneumatic relief valve) option is heat responsive device used with pneumatic actuators. This can be used in place of EP switch where a RRL is used. The PRV activates when temperature in excess of the temperature of the fusible link are detected. When the fusible link melts, air from the actuator is exhausted to close the dampers. Pneumatic actuators are to be piped per local code.

Pre-Installation Guidelines

The basic intent of a proper installation is to secure the fire or fire smoke damper in, not to, the opening in such a manner as to prevent distortion and disruption of damper operation. This is accomplished by allowing the fire or fire smoke damper in rated separation openings to expand and for the connecting duct to separate in the event of the collapse of the hanging system. The following items will aid in completing the damper installation in a timely and effective manner.

1) Check the schedules for proper damper locationswithin the building. Visually inspect the damper fordamage and verify that the Reusable Resettable Link(RRL) is in place or has not activated. Never installa fire damper without the proper UL approved RRLin place. (RRL is standard control option. Theseelectric links have a button for resetting.) If damperis furnished with fusible link, visually inspect the linkto verify its not missing or broken. Replace link asnecessary.

2) Lift or handle damper using sleeve or frame. Do notlift damper using blades or actuators.

3) Damper has label on outside of sleeve indicating a‘No Screw’ area. Do not install screws into this areaas screws may interfere with unexposed blade linkageand prevent damper blades from opening and/orclosing.


5) Damper must be installed into duct or opening squareand free of twist or other misalignment. Damper

must not be squeezed or stretched into duct or opening. Out of square, racked, twisted or misaligned installations can cause excessive leakage and/or torque requirements to exceed damper/actuator design.

ODFD-XXX, OFD-XXX, and OSSFD-XXX: Figure 2 shows installations that are also approved for curtain fire dampers. For access to inspect the damper and fusible link, refer to the requirements of NFPA 90A.

2. CLEARANCE REQUIREMENTS There is no minimum clearance requirement betweenthe wall/floor opening and the sleeve exterior (withthermal blanket attached). However, to facilitateinstallation, clearances between the wall/floor openingand the damper sleeve are recommended. althoughthere is no maximum allowable clearance, the minimumoverlap requirements between the wall/floor and theflange/retaining angle must be met. On grill mountinstallations the flange must overlap the wall/floor by1/2 in. (13mm). On continuous duct installations, theretaining angles must overlap the wall/floor by 1 in.(25mm). Because no clearances are required betweenthe wall/floor opening and the sleeve, dampers may notbe installed in the plane of the wall using this installationmethod.

Fig. 11. CLEARANCES REQUIRED BETWEEN FIRE DAMPER

SLEEVES AND WALL/FLOOR OPENINGS Fire damper and sleeve assemblies expand duringperiods of intense heat. Therefore, it is essential thatopenings in walls or floors be larger than the fire damperand sleeve assembly to allow for this expansion.Minimum clearances required between the outside of firedamper sleeve assemblies and wall/floor openings are:

• Galvanized steel fire dampers and sleeves: 1⁄8 in.(3mm) per foot of damper width and height with aminimum clearance of 1⁄4 in. (6mm), maximum of 1 1⁄2in. (38mm).

Recommended clearances, for width and/or height dimensions of:

1) 36 in. (914mm) or less: 1⁄2 in. (13mm) clearance

These are total clearances (ignoring fastener heads) and do not need to be equally spaced around the damper.

2. SLEEVE LENGTH AND WALL THICKNESS Insert the sleeved damper assembly into the preparedopening, to appropriate depth (refer to label on outsideof sleeve for location of damper in wall; see Dimension Aand Detail 1, Fig. 1).

Recommended maximum and minimum insertion depthcan be exceeded if:

1) The operation of the damper is not impeded and

2) The CL of the damper frame remains within the plane ofthe wall and

3) Attachments made through the retaining angle donot penetrate the ‘No Screw’ area designated on thedamper sleeve.

IMPORTANT: To avoid causing death or serious bodily harm to building occupants, do not penetrate the ‘No Screw’ area designated on the damper sleeve or the damper may not close properly.

The sleeve may extend a maximum of 16 in. beyond the wall on the actuator side of the damper and a maximum of 6 in. on the opposite side. Recommended standard sleeve lengths for various wall thicknesses are:

6. CONNECTION AND OPERATION OF TEMPERATURERESPONSE DEVICES (RRL STANDARD, OCI OPTION,AND TOR OPTION)

RRL - Dampers will be supplied with a thermostat-typetemperature response device, as a standard. The deviceis a RRL (resettable link device), which only incorporatesone thermostat and therefore the damper remains closedas soon as its sensor temperature is reached. The RRLdoes not contain blade indication switches. Refer to Fig.4 for wiring of the RRL thermostat.

OCI - The OCI (open or closed indicator) option containsa single pole, double throw switch used to indicate thedamper blade position. The switch provides a positiveopen or closed signal when used in conjunction withremote indicator lights. Refer to Fig. 5 & 6 for wiring ofthe OCI option.

TOR - The TOR (temperature override device) optionincorporates two thermostats with fixed settings (usually165°F [74°C] and 350°F [177°]). The primary sensor(the sensor with the lower temperature setting) can bebypassed by an external electrical signal allowing thedamper to reopen until the temperature reaches thesetting of the secondary sensor (the sensor with thehigher temperature setting). When the temperature of thesecondary sensor is exceeded the damper closes andremains closed thereafter (Figure 7).

The TOR assembly also contains a single pole, doublethrow switch used to indicate damper blade position. Theswitch provides a positive open or closed signal whenused in conjunction with remote indicator lights. SeeFig. 7 for wiring of the TOR thermostats and indicatorswitches.

If either the TOR or the RRL is ordered with a pneumaticactuator, an EP switch is required with an appropriateelectric power circuit to allow the electric thermostat tocontrol the pneumatic actuator.

PRV - The PRV (pneumatic relief valve) option is heatresponsive device used with pneumatic actuators. Thiscan be used in place of EP switch where a RRL is used.The PRV activates when temperature in excess of thetemperature of the fusible link are detected. When thefusible link melts, air from the actuator is exhausted toclose the dampers. Pneumatic actuators are to be pipedper local code.

Pre-Installation GuidelinesThe basic intent of a proper installation is to secure the fire smoke or fire damper in the opening in such a manner as to prevent distortion and disruption of damper operation. This is accomplished by allowing the fire or fire smoke damper in rated separation openings to expand and for the connecting duct to separate in the event of the collapse of the hanging system. The following items will aid in completing the damper installation in a timely and effective manner.

These instructions apply to 11/2 hour rated combination fire smoke and fire dampers mounted in: 1) masonry, block or stud walls and 2) concrete floors or ceilings. Specific requirements in these instructions are mandatory. Dampers must be installed in accordance with these instructions to meet the requirements of UL 555 and UL 555S. The installation of the damper and all duct connections to the damper sleeve shall conform to the latest editions of NFPA 90A, Standard for the Installation of Air Conditioning and Ventilating Systems, and the SMACNA Fire, Smoke and Radiation Damper Installation Guide, and UL Classifications R13317.


1) Check the schedules for proper damper locationswithin the building. Visually inspect the damper for damage and verify that the fusible link is in place or has not separated. If fusible link is not present or has separated, replace link. Never install a fire damper without the proper UL approved fusible link in place. (Fusible link is standard control option. An electric link may have been provided. Electric links have a button for resetting.)

2) Lift or handle damper using the frame. Do not liftdamper using blades or actuators.

3) Do not install screws into the main body area ofthe damper frame as screws may interfere with andprevent damper blade from opening and/or closing.

4) Damper has label indicating position of damperassembly in the wall. Install accordingly to complywith manufacturer’s appropriate UL Classification filenumber.

5) Damper must be installed into duct or opening free ofdistortion or other misalignment. Damper must not besqueezed or stretched into duct or opening. Out ofround, racked, twisted or misaligned installations cancause excessive leakage and/or torque requirementsto exceed damper/actuator design.

6) Damper and actuator must be kept clean andprotected from dirt, dust and other foreign materialsprior to and after installation. Examples of such

foreign materials include but are not limited to:a) Mortar dustb) Drywall dustc) Firesafing materialsd) Wall texturee) Paint overspray


8) Caulking is not necessary, nor is it allowed, betweenthe damper sleeve and the wall or floor opening(annular space). However, caulking may be applied tothe retaining plates.

9) ACCESS: Suitable access (such that fusible links,RRL’s, actuators, and linkages can be maintained)must be provided for damper inspection andservicing. Where it is not possible to achievesufficient size access, it will be necessary to install aremovable section of duct. (Refer to NFPA 90A).

1) the operation of the damper actuator is notimpeded and

2) the CL of the damper blade remains withinthe plane of the wall/floorIMPORTANT SAFETY DANGER! : To avoidcausing death or serious bodily harm tobuilding occupants, do not insert screwsinto the damper frame unless used for ductconnection within 2 in. (51mm) of the frameend.

The sleeve may extend a maximum of 16 in. (406mm) beyond the wall or floor on the actuator side of the damper and a maximum of 6 in. (152mm) on the opposite side.

4. SECURING THE DAMPER/SLEEVE ASSEMBLYTO WALL AND FLOOR OPENINGS

Damper assemblies must be installed in wall/floor openings using a single retaining plate on either side of the wall/floor or by using a retaining plate on both sides of the wall/floor. The use of a second retaining plate is allowed, but is not necessary. A single retaining plate is provided with the dampers. A second retaining plate can be ordered as an option. The outside dimension of the supplied retainer plate is nominal dia. + 41/2 inches (114mm).

3. ROUND DUCT CONNECTIONSRound duct connections to shall be attached with #8 or #10 sheet metal screws as follows:

• Ducts 22 in. (558mm) dia. and smaller shall havethree screws.

• Ducts larger than 22 in. (558mm) dia. up to andincluding 24 in. (610mm) dia. shall have five screws.

NOTE: All connections described may have duct sealant, PA2084T duct sealant adhesive manufactured by Precision, DP1010 water base duct sealant manufactured by Design Polymetrics, Grey Pookie, Ductmate PROseal®, or CL Ward S Seal applied inaccordance with SMACNA recommendations.

1. CLEARANCES REQUIRED BETWEEN FIREDAMPER SLEEVES AND WALL/FLOOROPENINGSFire damper assemblies expand during periods ofintense heat. Therefore, it is essential that openings inwalls or floors be larger than the fire damper assemblyto allow for this expansion. The wall/floor openingmust be a minimum of 7/8 in. (22mm) larger than theoutside diameter of the damper. Refer to Section 4 foradditional installation considerations.

38

6. CONNECTION AND OPERATION OFTEMPERATURE RESPONSE DEVICES (FusibleLink, RRL OPTION, OCI OPTION, TOROPTION, and PRV OPTION)

RRL - Dampers will be supplied with a fusible link temperature response device, as a standard. An optional thermostat type temperature response device may have been installed. The device is a RRL (resettable link device), which only incorporates one thermostat and therefore the damper remains closed as soon as its sensor temperature is reached. The RRL does not contain blade indication switches. Refer to Fig. 4.

OCI - The OCI (open or closed indicator) option contains a single pole, double throw switch used to indicate the damper blade position. The switch provides a positive open or closed signal when used in conjunction with remote indicator lights. Refer to Fig. 5 & 6.

These instructions apply to 11/2 hour rated combination fire smoke dampers mounted in masonry, block or metal stud walls, or concrete floors. Specific requirements in these instructions are mandatory. These instructions meet the requirements of UL555. Installation shall comply with the requirements of NFPA 90A (Installation of Air Conditioning and Ventilating Systems) and UL listing R13317.


1. DAMPER IS INSTALLED OUTSIDE OF WALL PLANEGFSD-XXX

Figure 1 shows two approved installations forcombination fire smoke dampers: 1) “Through thegrille access” and 2) installation in continuing duct.In grille-mount applications, the damper actuator canbe accessed by removing the grille and the actuatorcompartment cover plate. To provide access to thedamper actuator for continuing ductwork, refer to therequirements of NFPA 90A.

2. CLEARANCE REQUIREMENTS There is no minimum clearance requirement between thewall/floor opening and the sleeve exterior (with thermalblanket attached). However, to facilitate installation,clearances between the wall/floor opening and thedamper sleeve are recommended. Although there is nomaximum allowable clearance, the minimum overlaprequirements between the wall/floor and the flange/retaining angle must be met. On grille-mount installationsthe flange must overlap the wall/floor by 1/4 in. (6mm).

On continuous duct installations, the retaining angles must overlap the wall/floor by 1 in. (25mm). Because no clearances are required between the wall/floor opening and the sleeve, dampers may not be installed in the plane of the wall using this installation method.

3. DUCT TO SLEEVE CONNECTIONS Dampers are supplied with actuators (on applicablemodels) and sleeves from the factory and can beinstalled without the need for additional field installedsleeves.

Sleeve gauges of 16 or 14 (1.5mm - 2mm) are to beused. UL Standard 555 requires all ducts to terminate atfire damper sleeves. Sleeve thickness must not be lessthan the gauge of the connecting duct.

Duct to sleeve breakaway connections must be of the type described on page 10. Factory furnished round duct collars on type R and CR dampers are also considered to be breakaway connections and may be used.

4. SECURING THE DAMPER/SLEEVE ASSEMBLY TOWALL OPENINGS. Damper/sleeve assemblies must be installed in wallopenings using flanges and sheet metal screws asillustrated and described below.

• Flange on front (grille end) of sleeve must be a minimumof 14 gauge (2mm) steel and have a 3/4 in. (19mm)minimum flange leg (refer to Figure 2). Using #10(19mm) sheet metal screws, screw from inside of sleevethrough the rear portion of the studs (as shown inFigure 1). Space screws a maximum of 6 in. (152mm)on center and a maximum of 2 in. (51mm) from thecorners (minimum of 2 screws per side). No retainingangles are required on the side of wall opposite from thegrille.

4. SECURING THE DAMPER/SLEEVE ASSEMBLY TOWALL OPENINGS cont....• For continuous duct installations, the retaining angles

must be a minimum of 20 ga. (1mm). The leg of theretaining angle on the damper sleeve shall be aminimum of 11/4 in. (32mm). The leg of the retainingangle on the wall/floor shall be long enough to cover theannular space and overlap the wall/floor by a minimumof 1 in. (25mm)(see Figure 3).

• Retaining angles must be attached to the sleeve usingone or more of the following methods of attachment:

• Tack or spot welds• #10 (19mm) sheet metal screws• 1⁄4 in. (6mm) bolts and nuts• 3⁄16 in. (4.7mm) steel pop rivets

Attachments must be spaced a minimum of 6 in. (152mm) on center and a maximum of 2 in. (51mm) from corners. The angles must be attached to all 4 sides of the sleeve. A minimum of two attachments are required on each side, top and bottom. The angles need not be attached to each other at the corners.

Caution! Do not tear the thermal blanket during installation.

Dampers are tested for correct operation and are square and straight before shipment from the factory. Dampers must be installed square and straight and must not be twisted or racked. Failure to install the damper square and straight may prevent the damper blades from operating open and closed.

5. ACTUATOR CONNECTIONS Electrical and/or pneumatic connections to damperactuators should be made in accordance with wiring andpiping diagrams developed in compliance with applicablecodes, ordinances and regulations (see ElectricalGuidelines).
