Curtain Fire Dampers

Pre-Installation Guidelines

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 and
has not activated. Never install a fire damper without
the proper UL approved fusible link in place. Visually
inspect the link to verify its not damaged. Replace
link as necessary.
2) Lift or handle damper using sleeve or frame. Do not
lift damper using blades.
3) Dampers have a label indicating the required
mounting orientation. When the mounting orientation
is horizontal, the 'K side' must be up. Care must
be taken to ensure that the indicated orientation is
adhered to.

3 11/16 in.
Vertical Mount 4) Damper must be installed into duct or opening
(94mm)
square and free of twist or other misalignment.
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:
a) Mortar dust
b) Drywall dust
c) Firesafing materials
d) Wall texture
e) Paint overspray
6) Damper should be sufficiently covered as to prevent
overspray if wall texturing or spray painting will be
performed within 5 feet of the damper.
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 the fusible
link may be removed and the damper's blade stack
may be reset, 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).
9) The Code Authority Having Jurisdiction (AHJ) must
evaluate and provide approval of final installation
where variations to these instructions are necessary.
