Assembly Instructions
1. Refer to Figure 2 and Identify all components before
assembly.
2. Using specified fasteners, attach bottom panel (2)
to both side panels (3 & 4). Lap the side panels over
the bottom panel for waterproofing. Finger tighten.
3. Fasten both side panels (3 & 4) to the top panel (1).
Lap top panel over side panels for waterproofing
and fasten with specified hardware. Wide formed
edges must all be on the exterior side of the wall
mount collar. Finger tighten the fasteners.
4. Fasten both side flanges (7 & 8) to the side panels
(3 & 4). Use specified hardware (bolts, nuts, lock
washers, and flat washers) per flange and finger
tighten. (Place flat washers over slotted holes).
5. Fasten both top and bottom flanges (5 & 6) to the
top and bottom panels (1 & 2) using specified
hardware (bolts, nuts, lock washers, and flat
washers). (Place flat washers over slotted holes).
Tighten all fasteners securely. The wall mount collar
is now ready for installation.
6. If an optional damper is to be installed, slip the
damper flange under the damper lip of the wall
mount collar, see Figures 6 & 7. (If an optional
damper guard or weatherhood is to be installed,
see page 3). Using #12 x 3/4 inch self-drilling
screws and a 5/16 inch socket on the end of a
pneumatic or electric drill, run the self-drilling
screws through the holes provided on the damper
flange into the wall mount collar. Install additional
self-drilling screws in the damper flange including
both sides and the bottom. (On sizes 8 thru 20
do not use self-drilling screws on the damper lip).
