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.
These instructions apply to 11/2 hour rated combination fire smoke and fire dampers mounted in: 1) masonry, block or
stud walls and 2) concrete floors or ceilings. Specific requirements in these instructions are mandatory. Dampers must be
installed in accordance with these instructions to meet the requirements of UL 555 and UL 555S. The installation of the
damper and all duct connections to the damper sleeve shall conform to the latest editions of NFPA 90A, Standard
for the Installation of Air Conditioning and Ventilating Systems, and the SMACNA Fire, Smoke and Radiation Damper
Installation Guide, and UL Classifications R13317.
Installation -
Failure to follow these instructions will void all warranties.
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.
