2 Table of Contents Pre-Installation Guidelines....2 Installation...-4 Recommended Preparation of Openings in Wood and Metal Stud Walls...5 Breakaway Connections...6 Maintenance...7 Troubleshooting...7 Installation for Steel Stud Connection Option Pre-Installation Guidelines The basic intent of a proper installation is to secure the fire 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 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.. 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 procedure 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. 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 of spray-on insulating, wall texturing, or spray painting will be performed within 5 feet of the damper. Excessive dirt or foreign material deposits can cause damper to bind and not operate properly. 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 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). 10. The Code Authority Having Jurisdiction (AHJ) must evaluate and provide approval of final installation where variations to these instructions are necessary. 2

3 Installation - Failure to follow these instructions will void all warranties. These instructions apply to hour rated fire dampers mounted in masonry, block or stud walls and floors. Specific requirements in these instructions are mandatory. These instructions meet the requirements of UL 555. Installation shall comply with the requirements of NFPA 90A Standard for the Installation of Air Conditioning and Ventilating Systems. U.L. listing R117, California State Fire Marshal listings :102, and New York City BSA/MEA listing M apply to these dampers. 1. NO ADDITIONAL SLEEVES ARE REQUIRED The fire damper extended frame is an approved sleeve and can be properly installed without the need for a supplemental field installed sleeve. frame shall extend a maximum of 6 in. beyond the wall or floor opening on each side. 2. 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. 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. per foot of damper width and height with a minimum clearance of 1/4 in. Recommended clearances, for width and/or height dimensions of: 1) 48 in. or less: 1/2 in. clearance 2) More than 48 in. and 96 in. or less: 1 in. clearance ) More than 96 in.: 1 1 /2 in. clearance These are total clearances (ignoring fastener heads) and do not need to be equally spaced around the damper. Refer to Section and Figure 2 for additional installation considerations. Example: A 12 in. x 12 in. damper would require a minimum clearance of 1/4 in. A 48 in. x 12 in. damper would require a minimum clearance of 1/2 in. on width and 1/4 in. on height.. SECURING THE FIRE DAMPER TO WALL AND FLOOR OPENINGS (continues on next page). Fire damper assemblies must be installed in wall and floor openings using retaining angles on each side of the wall or floor as described below: angles must be a minimum of 16 gauge steel and have a minimum of in. x in. legs. angles must be attached to the damper using one or more of the following methods of attachment: tack or spot welds #10 sheetmetal screws 1/4 in. bolts and nuts /16 in. steel pop rivets Attachments must be spaced a maximum of 6 in. on centers and a maximum of 2 in. from corners. 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 must completely cover the clearance space between the damper and the wall/floor opening, plus overlap the wall/floor a minimum of 1 in. This coverage includes all corners (see Figure 2). angles must completely cover the clearance space between the damper and the wall/floor opening, plus overlap the wall/floor a minimum of 1 in. This coverage includes all corners (see Figure 2). Angle 2 in. Max. 6 in. Max. 6 in. Max. 2 in. Max. Min. 1 in. Overlap* *only applicable for damper sizes above 6 in. x 6 in. Figure 2: angle installation. Wall or Floor Angle Sleeve

4 angles should not be fastened to the wall/floor material. The angles should only sandwich the wall/floor and allow for damper expansion during periods of intense heat. For grille installation on fire dampers up through 6 in. x 6 in. maximum, angle legs may be reversed and one leg inserted into the wall/floor opening provided the required clearance is maintained between angle leg fasteners and the wall/floor opening. angles used in conjunction with grille installations must be a minimum of 16 gauge steel and have a minimum of 5/8 in. x 1 in. legs (this is only applicable to fire dampers up through 6 in. x 6 in.; fire dampers larger than 6 in. x 6 in. will still require a minimum of in. x in. legs) (see Figure ). 5/8 in. x 1in. 16 ga. angles minimum either inside or outside of sleeve. Angle can be located on outside surface of fire rated partition as shown in A, or mounted between the stud and the fire rated sheet rock as shown in B. A B 4. CONNECTING DUCTS TO THE FIRE DAMPER All duct connections to FD & DFD 150X series extended frame dampers must be breakaway type connections. All connections shown on page 6 are considered breakaway.
