Electrical Guidelines
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 it’s 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. 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 the 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.
Pre-Installation Guidelines
“UL CLASSIFIED (see complete marking on
product)”
“UL CLASSIFIED to Canadian safety standards
(see complete marking on product)”
Standard 555 & 555S (Listing #R13317)
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.
