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.
