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.
3. Install damper accordingly to comply with manufacturer's appropriate UL procedure file number.
4. Damper must be installed into duct or opening square and free of twist or other misalignment. Damper must not be
squeezed or stretched into duct or opening.
5. Damper 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:
6. Damper 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.
Installation -
Failure to follow these instructions will void all warranties.
These instructions apply to 11/2 hour rated fire dampers mounted in masonry, block or stud walls and concrete 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 R13317, California State Fire Marshal listings 3225-981:102, and New York City BSA/MEA listing 260-91-M as they
apply to these dampers.
note: Fire dampers are manufactured and labelled for either vertical or horizontal installation. The dampers must be
installed in accordance with the labelling.
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. Damper frame shall
extend a maximum of 6 in. (152mm) beyond the wall or
floor opening on each side.

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:
