RECEIVING AND HANDLING
Upon receiving dampers, check for both obvious and
hidden damage. If damage is found, record all necessary
information on the bill of lading and file a claim with the
final carrier. Check to be sure that all parts of the shipment,
including accessories, are accounted for.
Dampers must be kept dry and clean. Indoor storage
and protection from dirt, dust and the weather is highly
recommended. Do not store at temperatures in excess of
100°F.

Installation, Operation and Maintenance Instructions
Due to continuing research, Greenheck reserves the right to change specifications without notice.
SAFETY WARNING:
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, injury
or death. Read the installation, operating, and
maintenance instructions thoroughly before installing
or servicing this equipment.
WARRANTY
Greenheck warrants this equipment to be free from
defects in material and workmanship for a period of one
yearfromthepurchasedate.Anyunitsorpartswhich
prove to be defective during the warranty period will be
repaired or replaced at our option. Greenheck shall not
be liable for damages resulting from misapplication or
misuse of its products. Greenheck will not be responsible
for any installation or removal costs. Greenheck will not be
responsible for any service work or backcharges without
prior written authorization.

Pre-Installation Guidelines
The basic intent of a proper installation is to secure the fire 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 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 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.)
2. Lift or handle damper using sleeve or frame.
3. Install damper accordingly to comply with manufacturer’s appropriate UL procedure file number.
4. 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.
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ofspray-oninsulating,walltexturing,orspray
paintingwhenperformedwithin5feetofthedamper.Excessivedirtorforeignmaterialdepositscancausedamper
to bind and not operate properly.
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fusiblelinkscanbechanged)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.
These instructions apply to 1½ hour rated fire dampers mounted in masonry, block or stud walls and concrete floors. Specific
requirements in these instructions are mandatory. These instructions meet the requirements of UL 555. Installation shall
complywiththerequirementsofNFPA90AStandardfortheInstallationofAirConditioningandVentilatingSystems.U.L.

apply to these dampers.
Note: Fire dampers are manufactured and labelled for either vertical or horizontal installation. The dampers must be
installed in accordance with the labelling.
1. NO ADDITIONAL SLEEVES ARE REQUIRED
The fire damper extended frame is an approved sleeve
and can be properly installed without the need for a
supplemental field installed sleeve. Damper frame shall
extendamaximumof6in.(152mm)beyondthewallor
floor opening on each side.
Installation - Failure to follow these instructions will void all warranties.

OPENINGS
Fire damper assemblies expand during periods of
intense heat. Therefore, it is essential that openings in
walls or floors be larger than the fire damper assembly
toallowforthisexpansion.Minimumclearances
required between the outside of fire damper sleeve
assemblies and wall/floor openings are:

1. NO ADDITIONAL SLEEVES OR ANGLES ARE
REQUIRED
The fire damper extended frame is an approved sleeve
and the Steel Stud Connection (SSC) Option allows
fastening of the fire damper sleeve directly to the
wall's steel stud framing. Damper frame shall extend

2. INSTALLATION
Fire damper with SSC option must be in place before
the wall is constructed or it can be installed as the wall
is being constructed. Wall opening is framed around
the fire damper before sheet rock or other wall board
material is applied to the steel studs. This installation
provides appropriate protection for duct penetrations
in fire resistant wall construction using steel studs with
a fire resistance rating less than 3 hours. The following
wall design numbers (as detailed in the UL Fire
Resistance Directory) are appropriate for fire damper
installations using this SSC option:

Dampers do not typically require maintenance as long as they are kept dry and clean. If cleaning is necessary, use
mild detergents or solvents. If lubrication is desired, do not use oil-based lubricants or any other lubricants that attract
contaminant’s such as dust.
