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 1/8"(3mm) per linear foot (305mm) of height
and width of sleeved assembly up to a maximum of 11/2“(38mm) and a minimum of 1/4 “(6mm). For Static Systems the maximum
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 11/2and 3 hour fire
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 1/8" (3mm) per linear foot (305mm) of height
and width of sleeved assembly up to a maximum of 11/2“ (38mm) and a minimum of 1/4“ (6mm). The maximum single section is the
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 11/2hour 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 1/4" (6mm) and a maximum of 1/2“(13mm).
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 11/2hour 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, 1/4“(6mm) nut and bolts, 1/4“(6mm) tack welds, 3/16”(5mm) steel rivets, spot welds, or clinching (toggle) on 6" (152mm) centers.

4.Methods of Securing Damper in
Opening:
a. Two Angle (Two Sided) Method: This
method is the oldest and most commonly
used.This method is approved for use in UL
approved concrete/masonry partitions, steel
stud/gypsum walls, and wood stud/gypsum
walls. In this method 2 sets of angles are
used to secure the damper in the opening,
one on each side of the partition (See Fig. 7).
TwoAngle Method is approved for 1
1
/ 2 and 3
hour dampers, vertical or horizontal orienta-
tion, and any maximum size multi-section
UL approved damper (see Underwriter’s
Laboratories Listings for maximum assem-
bly sizes). Angles shall be a minimum of
1
1
/ 2 “ x 1
1
/ 2 “ (38mm x 38mm) x 16 gauge.
Angles are to be fastened to the sleeve on
6" (152mm) centers with #10 (M5) sheet
metal screws,
3
/ 16 " (5mm) steel pop rivets,
1
/ 2 “ (13mm) tack welds, or
1
/ 4 “ (6mm) di-
ameter nut and bolts with not more than
2" (51mm) from each end with a minimum
of two connections per side/leg.The angles
are to overlap the partition a minimum of
1" (25mm). These angles may be of a unit
type construction and may or may not be
fastened to each other at the corners. When
the duct work terminates at the damper or
installation prohibits angles from turning out/
away from the wall, the retaining angle shall
be reversed (leg turned into the opening)
providing the size of the opening is increased
by an amount equal to twice the combined
thickness of the angle and the height of the
screw or bolthead to maintain expansion
clearances. See note 1A for information on
clearances. See Fig. 7 for detailed drawings
of installations.
b. One Angle (Single Sided) Method:
In this method 1 set of angles are used
to secure the damper in the opening. This
method is approved for use in UL approved
concrete/masonry partitions and steel stud/
gypsum walls. Only one side of the fire parti-
tion will have the angles installed (see Fig.
8). One Angle Method is approved for 1
1
/ 2
hour dampers only, vertical and horizontal
(angles on top side only) orientations, and the
maximum size shall be 108” (2743mm) wide
or 108” (2743mm) high up to 36 square feet
(3.345 sq. meters) and up to the maximum
multi-section. UL approved damper size
(see Underwriter’s Laboratories Listings for
maximum assembly sizes). Angle shall be a
minimum of 1
1
/ 2 ” x 1
1
/ 2 ” (38mm x 38mm) by
16 gauge. Angles are to be fastened to the
sleeve on 6” (152mm) centers with #10 (M5)
sheet metal screws,
3
/ 16 ” (5mm) steel pop
rivets,
1
/ 2 ” (13mm) tack welds, or
1
/ 4 ” (6mm)
diameter nut and bolts with not more than
2” (51mm) from each end with a minimum
of two connections on each side/leg top and
bottom.The angles are also to be fastened to
the fire partition with: in concrete/masonry
partitions with #10 (M5) self-tapping concrete
anchors or concrete screws on 6” (152mm)
centers and must engage the fire partition
a minimum of 1
1
/ 2 ” (38mm); in steel stud/
gypsum partitions secure the angles to the
partition with #10 (M5) screws long enough
to penetrate the J-Runners and E-Stud by a
minimum of
3
/ 8 ” (10mm). Use a minimum
of two fasteners per side. The angles are
to overlap the partition a minimum of 1”
(25mm).These angles may be of a unit type
construction and may or may not be fastened
to each other at the corners. When the duct
work terminates at the damper or installa-
tion prohibits angles from turning out/away
from the wall, the retaining angle shall be
reversed (leg turned into the opening) pro-
viding the size of the opening is increased
by an amount equal to twice the combined
thickness of the angle and the height of the
screw or bolt head to maintain expansion
clearances. Angles can be placed in front of
or behind the drywall attaching directly to
the steel studs or masonry. PRICE’s Frame
Retaining Angles (FRA) can be used in place
of the angle mentioned above. See note 1B
for information on clearances. See Fig. 8 for
detailed drawings of installations.
c. No Angle Method: In this method No
angles are used to secure the damper in the
opening.This method is approved for use in
UL approved concrete/masonry partitions
and steel stud/gypsum walls. This method
uses a minimum
3
/ 4 ” (19mm) flange is on
one end of the sleeve. The damper/sleeve
assembly is placed in the opening so that the
flange rest flush up to the partition, then the
fasteners are placed through the sleeve into
the partition (see Fig. 9). NoAngle Method is
approved for 1
1
/ 2 hour dampers only, verti-
cal and horizontal (flange on top side only)
orientations, and the maximum size shall be
42” (1067mm) wide by 48” (1219mm) high up
to the maximum multi-section UL approved
damper size (see Underwriter’s Laboratories
Listings for maximum assembly sizes).The
sleeve flange shall be a minimum of
3
/ 4 ”
(19mm) high by 20 gauge steel. If a flange/
angle is added, it shall be a minimum of
1” x 1” (25mm x 25mm) by 18 gauge steel
and fastened with #10 (M5) bolts or screws,
1
/ 2 ” (13mm) welds, or
3
/ 16 ” (5mm) rivets to
the sleeve, at a maximum spacing of 6”
(152mm) o.c., not more than 2” (51mm) from
each end with a minimum of two fasteners
per side. The sleeve is to be fastened to
the fire partition with: in concrete/masonry
partitions with #10 self-tapping concrete
anchors or concrete screws on 6” (152mm)
centers and must engage the fire partition
a minimum of 1
1
/ 2 ” (38mm); in steel stud/
gypsum partitions secure the angles to the
partition with #10 (M5) screws long enough
to penetrate the J-Runners and E-Stud by a
minimum of
3
/ 8 ” (10mm). Use a minimum
of two fasteners per side.The sleeve flange
can be placed in front of or behind the dry-
wall attaching directly to the steel studs or
masonry. Be sure to not stretch the damper
when securing it into the partition. Stretch-
ing the damper can cause it to bind up and
prevent it from operating properly. PRICE’s
Frame Retaining Angles (FRA) can be used
in place of the angle mentioned above. See
note 1C for information on clearances. See
Fig. 9 for detailed drawings of installations.
