FS-1300 Combination Fire/Smoke Damper Installation Bulletin
!
DANGER: To avoid causing death or serious
bodily harm to building occupants,
allow for expansion of duct. Do not
fasten or weld the angles together
at the corners of the sleeve. Do
not secure the mounting angles to
the fire barrier.
6. While supporting the damper, install the mounting
angles to the sleeve on the other side of the fire
barrier, using the No. 10 self-tapping screws
provided.
Note: All sizes will have enough screws to be spaced
at 6-inch centers, starting within 3 inches from
the corners.

7. After installation, verify that the mounting angles
overlap the fire barrier by a minimum of 1 inch.
8. For proper damper operation, the frame must be
mounted square to prevent blade binding.
9. Visually inspect the damper to verify that the
fusible link is installed and was not damaged
during shipping.

Figure 11: Sleeve Connectors
10. Connecting ducts shall not be continuous and shall
terminate at the sleeve. The duct-to-damper sleeve
connection shall be of a breakaway style, such as
“S” or double “S” connectors. Use the plain “S” slip
when the duct or sleeve size is slightly different. Use
the double “S” slip when the sizes are equal.
11. The ducts connecting to the sleeves shall be equal
or less than the sleeve thickness. All FS-1300
sleeves are 18-gauge galvanized steel.

in accordance with NEC and local regulations.
1. Remove the four screws securing the cover to the
actuator. Remove the cover.
2. Remove the knock-out from the side of the
actuator.
3. Attach the conduit connector though the hole and
install the wires to the actuator.
