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.

3
These instructions apply to 1½hour rated combination fire smoke and fire dampers mounted (blades must be horizontal)
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.
Installation - Failure to follow these instructions will void all warranties.

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 C
Lof 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.
3. ROUND DUCT CONNECTIONS

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).
• The retaining plate(s) will open up for easy installation
when the clamping screw is loosened. If necessary,
remove the clamping screw and nut (see Fig. 2).
• Position the retaining plate between the blade axle and
the actuator shaft as shown in Figure 1. Do not place
the retaining plate in the groove. IMPORTANT: The
clamping mechanism should face away from the wall/
floor.
• Place the damper and attached retainer plate into the
wall/floor opening.
• If a second retaining plate is being used, secure it on
the opposite side of the wall/floor.
• Verify position, blade orientation, and actuator
clearance then tighten the retainer plate clamping
screws.
• The retainer plate(s) must overlap the wall/floor
opening a minimum of 1 inch (25mm).
• Secure the retainer plate(s) to the wall at the four
corners of each plate when two retainer plates are
used and also within ¾ in. (19mm) of the center
of each side when one retainer plate is used. The
following fasteners shall be used:
- #8 or #10 screws of a length such that the screw
engages the steel stud/track by ½ in. (13mm) (steel
framing)
- #8 or #10 screws of a length such that screw
engages the wood stud by 1¾ in. (44mm) (wood
framing)
- Steel anchors or self tapping concrete screws
penetrating masonry or block 1¼ in. (32mm).
5. ACTUATOR CONNECTIONS
Electrical and/or pneumatic connections to damper
actuators should be made in accordance with wiring and
piping diagrams developed in compliance with applicable
codes, ordinances and regulations (see Electrical
Guidelines).
6. CONNECTION AND OPERATION OF
TEMPERATURE RESPONSE DEVICES (Fusible
Link, RRL OPTION, OCI OPTION, TOR OPTION,
and PRV OPTION)
RRL - Dampers will be supplied with a fusible link
temperature response device, as a standard. An optional
thermostat type temperature response device may have
been installed. The device is a RRL (resettable link device),
which only incorporates one thermostat and therefore the
damper remains closed as soon as its sensor temperature
is reached. The RRL does not contain blade indication
switches. Refer to Fig. 4.

6.CONNECTION AND OPERATION OF TEMPERATURE
RESPONSE DEVICES (Fusible Link, RRL OPTION,
OCI OPTION, TOR OPTION, and PRV OPTION)
continued....
OCI - The OCI (open or closed indicator) option contains
a single pole, double throw switch used to indicate the
damper blade position. The switch provides a positive open
or closed signal when used in conjunction with remote
indicator lights. Refer to Fig. 5 & 6
TOR - The TOR (temperature override device) option
incorporates two thermostats with fixed settings (usually
165°F [74°C] and 350°F [177°C]). The primary sensor (the
sensor with the lower temperature setting) can be bypassed
by an external electrical signal allowing the damper to
reopen until the temperature reaches the setting of the
secondary sensor (the sensor with the higher temperature
setting). When the temperature of the secondary sensor is
exceeded the damper closes and remains closed thereafter
(Fig. 7)
The TOR assembly also contains a single pole, double throw
switch used to indicate damper blade position. The switch
provides a positive open or closed signal when used in
conjunction with remote indicator lights. See Fig. 6 for wiring
of the TOR thermostats and indicator switches.
If either the TOR or the RRL is ordered with a pneumatic
actuator, an EP switch is required with an appropriate
electric power circuit to allow the electric thermostat to
control the pneumatic actuator.
PRV - The PRV (pneumatic relief valve) option is heat
responsive device used with pneumatic actuators. This
can be used in place of EP switch where a RRL is used.
The PRV activates when temperature in excess of the
temperature of the fusible link are detected. When the
fusible link melts, air from the actuator is exhausted to close
the dampers. Pneumatic actuators are to be piped per local
code.

Damper Maintenance
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 for components such as axle bearings, jackshaft bearings
and jamb seals, do not use oil-based lubricants or any other lubricants that attract contaminants such as dust.
Dampers and their actuator(s) must be maintained, cycled, and tested a minimum in accordance with:
• The latest editions of NFPA 80, 90A, 92A, 92B, 101, 105, UL864, AMCA 503-03 and local codes.
• Actuator manufacturer recommendations.
Damper Troubleshooting
The following is a possible cause and correction list for common concerns with the dampers.
Symptom Possible Cause Corrective Action
Damper does not fully
open and/or close
Frame is 'racked' causing blades to bind on
jamb seals
Adjust frame such that it is square and plumb
Actuator linkage loose Close damper, disconnect power, adjust and tighten link-
age
Defective motor Replace
Screws in damper linkage Damper installed too far into wall. Move out to line as
designated on damper label
Contaminants on damper Clean with a non-oil based solvent (see Damper Mainte-
nance)
RRL or TOR sensor tripped Heat Push reset button located on backside of RRL or TOR
Damper does not operate No power supplied to the actuator Add power supply
