Fire Dampers (Static & Dynamic)
Installation Instructions
Important General Notes:
When UL is referred to in this document, it represents UL/ULC. This installation instruction applies to Fire Dampers (static,
dynamic, curtain, single and multi-blade types) mounted in the plane of an UL approved fire partition. The dampers are designed for
operation in the vertical or horizontal position with blades running horizontal. The dampers are to be installed square and free from
twisting or racking.
The dampers shall not be compressed or stretched into the opening. Transportation and installation of the dampers shall be handled
with the sleeve or frame. Do not lift the damper with the blades or actuator. Special care shall be given to the damper before instal-
lation and after to insure it is protected against dirt, weather, mortar and drywall dust, wall texture and paint. Any of these conditions
could cause the damper not to operate correctly and void the warranty. Suitable access to inside duct is to be provided for inspection
and replacement of parts such as heat response devices and actuators per NFPA 90A and local authority having jurisdiction. As with all
joints, contractor must seal duct-collar connections in the field after installation. PRICE Model numbers which are UL approved to utilize
this installation are FD, FD-SL, FD-USL, FD-MB-3V, FD-MB-AF , FD-SB, FDD, FDD-SL, FDD-MB-3V, FDD-MB-AF .
1. Opening Preparation/Clearances:
The fire barrier opening shall be larger than the damper to allow for thermal expansion and ease of installation. When steel stud/gypsum
or wood stud/gypsum partitions are being used then refer to Fig. 1-3 for additional information and details.
A. Dampers Assemblies Using 2 Angles Methods (see note 4a) shall be a minimum of
and width of sleeved assembly up to a maximum of 1
single section curtain damper is 60"x60" (1524mm x 1524mm) for vertical mounting and 40" x 40" (1016mm x 1016mm) for horizontal
mountings, based on type "A" dampers. The maximum single section multi-blade damper is 36" x 48" (914mm x1219mm) in vertical
or horizontal mountings For Dynamic Systems the maximum single section curtain damper is 36" x 36" (914mm x 914mm) in verti-
cal mountings and 18" x 18" (457mm x 457mm) in horizontal mountings, based on type "A" dampers. The maximum single section
multi-blade damper is 36"x48" (914mm x 1219mm) in vertical or horizontal mountings. This method is acceptable for 1
dampers. See Underwriter's Laboratories Listings for maximum multiple assembly sizes.
B. Dampers Assemblies Using 1 Angle Methods (see note 4b) shall be a minimum of
and width of sleeved assembly up to a maximum of 1
same as in A above. The maximum multi-section is 108"w and 108"h (2743mm x 2743mm) up to 36 square feet (3.345 sq. meters). This
method is acceptable for 1 / hour fire dampers mounted in a masonry/concrete or steel stud/ gypsum wall only.

C. Dampers Assemblies Using No Angles Methods (see note 4c) shall be a minimum of
The maximum single section is the same as in A above. The maximum multi-section is 42"w x 48"h (1067mm x 1219mm). This method
is acceptable for 1 1 / hour fire dampers mounted in a masonry/concrete or steel stud/gypsum wall only.

2. Damper Sleeves and Breakaway Connections:
Sleeves shall be of the SAME GAUGE or heavier as the duct to which it is attached, if one of the breakaway connection is used as de-
fined in the SMACNA Fire, Smoke and Radiation Damper Guide for HVAC Systems (Fig. 4-6) and in NFPA 90A. Gauges shall conform
to SMACNA or ASHRAE duct standards. Sleeves shall not extend beyond the fire barrier more than 6" (152mm) unless an actuator or
factory installed access door is supplied, then the sleeve may extend up to 16" (406mm). Sleeve shall terminate at both sides of wall
within dimensions shown. If a rigid connection is used, then the sleeve shall be a minimum of 16 gage for dampers up to 36" (914mm)
wide by 24" (610mm) high and 14 gage for dampers exceeding 36"(914mm) wide by 24" (610mm) high.
Round and oval breakaway connections must use either a 4" (102mm) wide draw band or #10 (M5) sheet metal screws spaced equally
around the circumference of the duct as follows: 3 screws for duct sizes 22" (559mm) and smaller; 5 screws for duct sizes greater than
22" (559mm) and up to and including 36" (914mm): 8 screws for duct sizes greater than 36" (914mm). Refer to SMACNA Fire, Smoke
and Radiation Damper Guide for HVAC Systems for information on Ductmate, Nexus, Ward, TDC and TDF systems and any additional
information (Fig. 5-6). A sleeve may not be required if the damper frame is of sufficient size and shape so the mounting angles can be
directly fastened to it.
3. Multi-Section and "Damper to Sleeve" Connections:
Damper shall be secured to the sleeve and to each other (when joined to make multiple damper assemblies) with #10 sheet metal
screws, / "(6mm) nut and bolts,
