Pre-Installation Guidelines

The 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.

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. Electric links have a button for resetting.)

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

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)Damper has label indicating position of damper assembly in the wall. Install accordingly to comply with manufacturer’s appropriate UL Classification file number.

5)Damper must be installed into duct or opening free of distortion or other misalignment. Damper must not be squeezed or stretched into duct or opening. Out of round, racked, twisted or misaligned installations can cause excessive leakage and/or torque requirements to exceed damper/actuator design.

6)Damper and actuator 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)Damper 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 plates.

9)ACCESS: Suitable access (such that fusible links, RRL’s, actuators, and linkages 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).

10)The Code Authority Having Jurisdiction (AHJ) must evaluate and provide approval of final installation where variations to these instructions are necessary.
