Figure 4: Sleeve Lengths for Wall Sizes
Standard FD-1300 Fire Dampers have no sleeve, but
may be ordered as an option with a 20 inch deep,
18-gauge galvanized sheet metal sleeve from the
factory.
Refer to Figure 4 for appropriate sleeve dimensions
when not provided by Johnson Controls. Determine
proper sleeve length by adding at least 2 inches, but
no more than 6 inches, to each side of the wall or floor
thickness, as illustrated by examples in Figure 4.
Example: A 12 inch fire wall would require a 16 inch
minimum or 24 inch maximum sleeve.
Field-manufactured sleeves are to be made of
10 to 20-gauge galvanized sheet metal. All
factory-ordered sleeves are 18-gauge galvanized sheet
metal.
To install FD-1300 Fire Dampers into
non-Johnson Controls manufactured sleeves:
1.
Form the sheet metal to fit around the damper
frame.
2.
Preferably from the inside, or from the outside, drill
holes through the sleeve matching the holes in the
damper channels shown in Figure 3.
Additional holes through the top and bottom
channels will be required. These holes will be on
6 inch centers.
3.
Use No. 10 x 1/4 inch long self-tapping screws to
secure the sleeve to the damper.
!
DANGER: To avoid causing death or
serious bodily harm to building
occupants, do not use screws on
the top or bottom of the damper
longer than 1/4 inch.
