This is accomplished by allowing the fire 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 locations within the building. Visually inspect the damper for damage and verify that the fusible link is in place or has not activated. Never install a fire damper without the proper UL approved fusible link in place. If damper is furnished with fusible link, visually inspect the link to verify its not missing or broken. Replace link as necessary. 2) Lift or handle damper using sleeve or frame. Do not lift damper using blades. 3) has label on outside of sleeve indicating a No Screw area. Do not install screws into this area as screws may interfere with unexposed blade linkage and prevent damper blades from opening and/or closing. 4) has label indicating position of damper and sleeve assembly in the wall. Install accordingly to comply with manufacturer s appropriate UL Classification file number. 5) must be installed into duct or opening square and free of twist or other misalignment. 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. 6) must be kept clean and protected from dirt, dust and other foreign materials prior to and after installation. Examples of such foreign materials include but are not limited to: a) Mortar dust b) Drywall dust c) Firesafing materials d) Wall texture e) Paint overspray 7) should be sufficiently covered as to prevent overspray if wall texturing or spray painting will be performed within 5 feet of the damper. Excessive dirt or foreign material deposits on damper can cause excessive leakage and/or torque requirements to exceed damper/actuator design. 8) Caulking is not necessary, nor is it allowed, between the damper sleeve and the wall or floor opening (annular space). However, caulking may be applied to the retaining angles. 9) ACCESS: Suitable access (such that fusible links can be maintained, etc.) must be provided for damper inspection and servicing. Where it is not possible to achieve sufficient size access, it will be necessary to install a removable section of duct. (Refer to NFPA 90A). 10) The Code Authority Having Jurisdiction (AHJ) must evaluate and provide approval of final installation where variations to these instructions are necessary. 1. CLEARANCES REQUIRED BETWEEN FIRE DAMPER SLEEVES AND WALL/FLOOR OPENINGS Fire damper and sleeve assemblies expand during periods of intense heat. Therefore it is essential that openings in walls or floors be larger than the fire damper and sleeve assembly to allow for this expansion. Minimum clearances required between the outside of fire damper sleeve assemblies and wall/floor openings are: Galvanized steel fire dampers and sleeves: 1/8 in. (3mm) per foot of damper width and 1/8 in. (3mm) per foot height with a minimum clearance of 1/4 in. (6mm) 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) or less: 1 in. (25mm) clearance 3) More than 96 in. (2438mm): 1 1/2 in. (38mm) clearance Stainless steel fire dampers and stainless steel or galvanized sleeves: 3/16 in. (4.8mm) per foot of damper width and height with a minimum clearance of 1/4 in. (6mm), of 2 in. (51mm). Recommended clearances, for width and/or height dimensions of: 1) 48 in. (1219mm) or less: 3/4 in. (19mm) clearance 2) More than 48 in. (1219mm) and 96 in. (2438mm) or less: 1 1/2 in. (38mm) clearance 3) More than 96 in. (2438mm): 2 in. (51mm) 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. 3

All four sides of the damper frame must be attached to the sleeve with one row of attachments on each side of the blade channel. Attachments must be spaced a of 6 in. (152mm) on centers and a of 2 in. (51mm) from corners. A minimum of 4 attachments (2 on each side of the blade channel ) per side (16 per damper) are required. One of the methods of attachment shown below must be used. tack or spot welds #10 sheet metal screws 1 /4 in. (6mm) bolts and nuts 3 /16 in. (4.7mm) steel pop rivets 4. SECURING FIRE DAMPER AND SLEEVES TO WALL AND FLOOR OPENINGS. The fire damper must be installed such that the centerline of the blades are mounted in the plane of the wall or floor. Fire damper and sleeve assemblies must be installed in wall and floor openings using retaining angles on each side of the wall or floor as described below: angles for 11/2 hour rated dampers with a width and height 48 in. (1219mm) or less must be a minimum of 20 ga. (1mm). angles for all 3 hour rated dampers and all dampers with a width or height greater than 48 in. (1219mm) must be a minimum of 16 gauge (1.5mm). The leg of the retaining angle on the damper sleeve shall be a minimum of 11/4 in. (32mm). The leg of the retaining angle on the wall/floor shall be long enough to cover the annular space and overlap the wall/floor by a minimum of 1 in. (25mm). (See Figure 4). angle legs may be reversed with leg of retaining angle with annular space of opening so angle and sleeve is flush against barrier. angles must be attached to the sleeve using the procedures and methods described in Section 3. The angles must be attached to all 4 sides of the sleeve with butt joints at each corner. 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. angles should not be fastened to the wall/ floor material. The angles should only sandwich the wall/floor and allow for damper/sleeve expansion during periods of intense heat. For single retaining angle applications, see Single Side Supplement (#474015). No Connecting or Transfer Opening Openings where duct does not attach on either side will not require a breakaway connection. Transfer openings are typical of a non-ducted installation (see Figure 2). may end flush with the rated wall/floor on both sides Refer to Section 4 for securing retaining angles to sleeves. 5. CONNECTING DUCTS TO FIRE DAMPER SLEEVE Any duct connection other than breakaway is considered rigid. The connections shown on this page are considered breakaway. Factory furnished duct collars on type R and CR fire dampers are also considered breakaway (see Figure 1). 6 Figure 2 Transfer opening or no connecting duct Attachments--Do not place attachments between blade channels Blade Channel 2 in. Max. 6 in. Max. NOTE: Attachments must not enter blade channel or they may cause interference with blade closure. Narrow Line and Ultra Thin dampers do not have flange for attachments and must be welded to sleeve. Attachments can be staggered or evenly spaced.

This is accomplished by allowing the fire 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 locations within 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.) 2. Lift or handle damper using sleeve or frame. 3. Install damper accordingly to comply with manufacturer s appropriate UL procedure file number. 4. must be installed into duct or opening square and free of twist or other misalignment. must not be squeezed or stretched into duct or opening. 5. must be kept clean and protected from dirt, dust and other foreign materials prior to and after installation. Examples of such foreign materials include, but are not limited to: a. Mortar dust b. Drywall dust c. Firesafing materials d. Wall texture e. Paint overspray 6. should be sufficiently covered as to prevent overspray of spray-on insulating, wall texturing, or spray painting when performed within 5 feet of the damper. Excessive dirt or foreign material deposits can cause damper to bind and not operate properly. 7. Caulking is not necessary, nor is it allowed, between the damper sleeve and the wall or floor opening (annular space). However, caulking may be applied to the retaining angles. 8. ACCESS: Suitable access (such that fusible links can be changed) must be provided for damper inspection and servicing. Where it is not possible to achieve sufficient size access, it will be necessary to install a removable section of duct. (Refer to NFPA 90A). 9. The Code Authority Having Jurisdiction (AHJ) must evaluate and provide approval of final installation where variations to these instructions are necessary. 11

Therefore, it is essential that openings in walls or floors be larger than the fire damper assembly to allow for this expansion. Minimum clearances required between the outside of fire damper sleeve assemblies and wall/floor openings are: Galvanized steel fire dampers and sleeves: 1/8 in. (3mm) per linear foot of damper width and height with a minimum clearance of 1/4 in. (6mm).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) or less: 1 in. (25mm) clearance 3) More than 96 in. (2438mm): 11/2 in. (38mm) clearance These are total clearances (ignoring fastener heads) and do not need to be equally spaced around the damper.

19 Table of Contents Pre-Installation Guidelines...19 Installation Maintenance...19 Troubleshooting...19 Pre-Installation Guidelines The basic intent of a proper installation is to secure the 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 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 locations within the building. Visually inspect the damper for damage and verify that the fusible link is in place or has not separated. s will be supplied with a temperature responsive fusible link device. 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. 2) Lift or handle damper using the frame. Do not lift damper using blades. 3) Do not install screws into the main body area of the damper frame as screws may interfere with and prevent damper blade from opening and/or closing. 4) must be installed into duct or opening free of distortion or other misalignment. must not be squeezed or stretched into duct or opening. Out of round, racked, twisted or misaligned installations can cause torque requirements to exceed damper design. 5) must be kept clean and protected from dirt, dust and other foreign materials prior to and after installation. Examples of such foreign materials include but are not limited to: 1) Mortar dust 2) Drywall dust 3) Firesafing materials 4) Wall texture and 5) Paint overspray. 6) should be sufficiently covered to prevent overspray if wall texturing or spray painting will be performed within 5 feet of the damper. Excessive dirt or foreign material deposits on damper can cause torque requirements to exceed damper design. 7) Caulking is not allowed between the damper sleeve and the wall or floor opening (annular space). However, caulking may be applied to the retaining plates and a field-applied sealant may be required for the damper sleeve and transitions to meet certain duct leakage standards. 8) ACCESS: Suitable access (such that fusible links can be maintained) must be provided for damper inspection and servicing. Where it is not possible to achieve sufficient size access, it will be necessary to install a removable section of duct. (Refer to NFPA 90A). 9) The Code Authority Having Jurisdiction (AHJ) must evaluate and provide approval of final installation where variations to these instructions are necessary. Installation - Failure to follow these instructions will void all warranties. These instructions apply to 1 1/2 hour rated fire dampers mounted (blades must be horizontal) in: 1) masonry, block or stud walls and 2) concrete floors or ceilings. Specific requirements in these instructions are mandatory. s must be installed in accordance with these instructions to meet the requirements of UL 555. 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 Installation Guide, and UL Classifications R

20 Installation - Continued 1. CLEARANCES REQUIRED BETWEEN FIRE DAMPER SLEEVES AND WALL/FLOOR OPENINGS Fire damper assemblies expand during periods of intense heat. Therefore, it is essential that openings in walls or floors be larger than the fire damper assembly to allow for this expansion. The wall/floor opening must be a minimum of 7 /8 in. (22mm) larger than the outside diameter of the damper. Refer to Section 4 for additional installation considerations. RETAINER PLATE (OPTIONAL) DUCT CONNECTION AREA 2 in.

DUCT TO SLEEVE CONNECTIONS s are supplied with sleeves from the factory SECURING THE DAMPER/SLEEVE ASSEMBLY TO WALL AND FLOOR OPENINGS 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 retaining plate(s) will open up for easy installation when the clamping screw is loosened. If necessary, remove the clamping screw and nut (see Fig. 2). (IMPORTANT: The clamping mechanism should face away from the wall/floor). Retainer plate(s) are designed to mount flush to the wall/floor and hold the damper in the wall/floor opening. Place the damper and attached retainer plate into the wall/floor opening. If a second retaining plate is being used, secure it on the opposite side of the wall/floor DO NOT POSITION RETAINER PLATE(S) IN FRAME GROOVE Verify position, blade orientation, and actuator clearance then tighten the retainer plate clamping screws. The retainer plate(s) must overlap the wall/floor opening a minimum of 1 inch (25mm).

CLEARANCE REQUIREMENTS There is no minimum clearance requirement between the wall/floor opening and the sleeve exterior (with thermal blanket attached). However, to facilitate installation, clearances between the wall/floor opening and the damper sleeve are recommended. although there is no allowable clearance, the minimum overlap requirements between the wall/floor and the flange/retaining angle must be met. On grill mount installations the flange must overlap the wall/floor by 1 2 in. (13mm). 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. 25
