Pre-Installation Guidelines
The basic intent of a proper installation is to secure the
fire or fire smoke 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 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 Reusable Resettable Link
(RRL) is in place or has not activated. Never install a
fire damper without the proper UL approved RRL in
place. (RRL is standard control option. These electric
links have a button for resetting.) If damper is furnished
with fusible link, visually inspect the link 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 has label on outside of sleeve indicating a
‘No Screw’ area. Do not install screws into this area as
screws may interfere with unexposed blade linkage and
prevent damper blades from opening and/or closing.
4) Damper has label indicating position of damper
and sleeve 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 square
and free of twist or other misalignment. Damper must
not be squeezed or stretched into duct or
opening. Out of square, 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 angles.
9) 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).
10) The Code Authority Having Jurisdiction (AHJ) must
evaluate and provide approval of final installation where
variations to these instructions are necessary.
Electrical Guidelines
All wiring shall be done in accordance with the National
Electrical Code ANSI/NFPA-70 latest edition, any local
codes that may apply, and wiring diagrams developed
in compliance with the job or project design and
specifications.
Important!
Electrical input may be needed for this equipment. This
work should be performed by a qualified electrician.
Verify power before wiring actuator. Greenheck is not
responsible for any damage to, or failure of the unit
caused by incorrect field wiring. To avoid causing death
or serious bodily harm to building occupants, follow all
instructions carefully. Dampers must close completely to
preserve the integrity of the fire smoke separation.
