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.
Safety Caution!
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.
Electrical Guidelines

These instructions apply to 11 /2hour rated combination fire smoke dampers mounted (blades must be vertical) in: masonry,
block, or stud walls. Specific requirements in these instructions are mandatory. Dampers must be installed in accordance with
these instructions to meet the requirements of UL555 and UL555S. The installation of the damper and all duct connections
to the damper sleeve shall conform to the latest editions of NFPA90A, 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 and sleeve assemblies expand during
periods of intense heat. Therefore, it is essential that
openings in walls or floors be larger than the fire damper
and sleeve assembly to allow for this expansion.
Minimum clearances required between the outside of
fire damper sleeve assemblies and wall/floor openings
are:
• Galvanized steel fire dampers and sleeves: 1⁄8in.
(3mm) per foot of damper width and height with a
minimum clearance of 1⁄4in. (6mm), maximum of 1
1⁄2in. (38mm).
Recommended clearances, for width and/or height
dimensions of:
1) 36 in. (914mm) or less: 1⁄2in. (13mm) clearance
These are total clearances (ignoring fastener heads) and
do not need to be equally spaced around the damper.
2. SLEEVE LENGTH AND WALL THICKNESS
Insert the sleeved damper assembly into the prepared
opening, to appropriate depth (refer to label on outside
of sleeve for location of damper in wall; see Page 3,
Dimension A and Detail 1, Fig. 1).
Recommended maximum and minimum insertion depth
can be exceeded if:
1) The operation of the damper is not impeded and
2) The C
Lof the damper frame remains within the plane
of the wall and
3) Attachments made through the retaining angle do
not penetrate the ‘No Screw’ area designated on the
damper sleeve.
IMPORTANT SAFETY DANGER! : To avoid causing
death or serious bodily harm to building occupants, do
not penetrate the ‘No Screw’ area designated on the
damper sleeve or the damper may not close properly.
The sleeve may extend a maximum of 16 in. beyond the
wall on the actuator side of the damper and a maximum
of 6 in. on the opposite side. Recommended standard
sleeve lengths for various wall thicknesses are:

3. DUCT TO SLEEVE CONNECTIONS
Dampers are supplied with sleeves and actuators from
the factory and can be installed without the need for
additional field installed sleeves.
Gauge of factory furnished sleeve determines the type
of duct to sleeve connections required (see table below).
Any duct connection other than those breakaway
connections described on page 6 are considered rigid.
Factory furnished duct collars, type R and O, are also
considered breakaway (see Fig. 2).

See page 6 for additional information on breakaway sleeve connections.
Sleeve thickness must not be less than the gauge of the connecting duct.
UL Standard 555 requires all ducts to terminate at fire damper sleeves.
4. SECURING THE DAMPER/SLEEVE ASSEMBLY TO
WALL OPENINGS
Damper/sleeve assemblies must be installed in wall
openings using retaining angles on at least one side of
the wall as described below:
• Retaining angle must be a minimum of 16 gauge
(1.5mm) steel and have a minimum of 1
1
/2in. x 1
1
/2in.
(38mm x 38mm) legs.
• Retaining angle must be attached to the damper using
one or more of the following methods of attachment
(refer to label on outside of sleeve for ‘No Screw’
area):
• Tack or spot welds
• #10 (3/4in. max. [19mm]) sheet metal screws
• 1/4in. (6mm) bolts and nuts
•3/16 in. (5mm) steel pop rivets
A minimum of two connections per side, top, and
bottom, 12 in. (305mm) O.C. maximum for openings of
48 in. W x 32 in. H (1219mm x 812mm) and less, and
6 in. (152mm) O.C. for openings 100 in. W x 32 in. H
(2540mm x 32mm) or less. The angles must be attached
to all 4 sides of the sleeve with butt joints at each
corner. A minimum of two attachments are required
on each side, top and bottom. Ensure that attachment
device does not interfere with the operation of the
damper and the free movement of the damper blades.
The angles need not be attached to each other at the
corners. Do not secure the retaining angle to the fire
separation (see Fig. 3).
• Retaining angles must completely cover the
clearance space between the damper and the wall
opening, plus overlap the wall a minimum of 1 in. This
coverage includes all corners.
• Retaining angles should not be fastened to the wall
material. The angles should only sandwich the wall
and allow for damper expansion during periods of
intense heat.

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 (RRL STANDARD, OCI OPTION,
AND TOR OPTION)
RRL - Dampers will be supplied with a thermostat-
type temperature response device, as a standard. 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 for wiring of the RRL
thermostat.
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 for wiring of the
OCI option.
TOR - The TOR (temperature override device) option
incorporates two thermostats with fixed settings (usually
165°F [74°C] and 350°F[177°]). 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 (Figure 6).
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 page 6, 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.
7. RECOMMENDED PREPARATION OF OPENINGS IN
WOOD AND METAL STUD WALLS
• Frame wall openings as shown. (see Fig. 7 & 8)
• Double vertical studs are not required for openings
36 in. x 36 in. (914mm x 914mm) or smaller.
• Gypsum wall board must be fastened 12 in. (350mm)
on center to all stud and runner flanges surrounding
opening. (see Fig. 9)
• All construction and fasteners must meet the
requirements of the appropriate wall design (See UL
Fire Resistance Directory) and/or local codes.

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.
Sympton 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 linkage
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 Maintenance)
RRL or TOR sensor
tripped
Heat Push reset button located on backside of
RRL or TOR
Damper does not
