The following items will aid in completing the damper
installation in a timely and effective manner.
1) Check the drawings for proper damper locations
within the building. Visually inspect the damper for
damage and verify that the Reusable Resettable Link
(RRL) is in place and has not activated if provided.
These electric links have a button for resetting.
Visually inspect the fusible link (if provided) 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 or actuators.
3) Damper must be installed into duct or opening
square and free of twist or other misalignment. Out
of square, racked, twisted or misaligned installations
can cause excessive leakage and/or torque
requirements to exceed damper/actuator design.
4) 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
5) 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 the damper can
cause excessive leakage and/or torque requirements
to exceed damper/actuator design.
6) 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.
7) ACCESS: Suitable access (such that RRL’s and
actuators 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).
8) The Code Authority Having Jurisdiction (AHJ) must
evaluate and provide approval of final installation
where variations to these instructions are necessary.
