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 (38°C).

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. 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.

SAFETY CAUTION!

Electrical input may be needed for this equipment. This
work should be performed by a qualified electrician.

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.

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.

Installation - Failure to follow these instructions will void all warranties.

These instructions apply to 1½ 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.

1. CLEARANCES REQUIRED BETWEEN FIRE
DAMPER SLEEVES AND WALL/FLOOR
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. The wall/floor opening
must be a minimum of 7/8 in. (22mm) larger than the
outside diameter of the damper. Refer to Section 4 for
additional installation considerations.

2. SLEEVE LENGTH AND WALL/FLOOR
THICKNESS

Insert the damper assembly into the prepared opening,
to appropriate depth (see Fig. 1).

Recommended maximum and minimum insertion depth
can be exceeded if:

1) the operation of the damper actuator is not
impeded and

2) the CL of the damper blade remains within
the plane of the wall/floor

IMPORTANT SAFETY DANGER! : To avoid

causing death or serious bodily harm to
building occupants, do not insert screws
into the damper frame unless used for duct
connection within 2 in. (51mm) of the frame
end.

The sleeve may extend a maximum of 16 in. (406mm)
beyond the wall or floor on the actuator side of the
damper and a maximum of 6 in. (152mm) on the
opposite side.

Fig. 1

3. ROUND DUCT CONNECTIONS

Round duct connections to shall be attached with #8 or
#10 sheet metal screws as follows:

• Ducts 22 in. (558mm) dia. and smaller shall have
three screws.

• Ducts larger than 22 in. (558mm) dia. up to and
including 24 in. (610mm) dia. shall have five screws.

NOTE: All connections described may have duct
sealant, PA2084T duct sealant adhesive manufactured
by Precision, DP1010 water base duct sealant
manufactured by Design Polymetrics, Grey Pookie,
Ductmate PROseal®, or CL Ward S Seal applied in
accordance with SMACNA recommendations.

4. SECURING THE DAMPER/SLEEVE ASSEMBLY
TO WALL AND FLOOR OPENINGS

Damper assemblies must be installed in wall/floor
openings using a single retaining plate on either side of
the wall/floor or by using a retaining plate on both sides
of the wall/floor. The use of a second retaining plate is
allowed, but is not necessary. A single retaining plate
is provided with the dampers. A second retaining plate
can be ordered as an option. The outside dimension of
the supplied retainer plate is nominal dia. + 4½ inches
(114mm).
