1. Insert 1/2 in. (12.7 mm) diameter threaded rod (by others) into
hanger brackets on the supply plenum top. Raise and hang
the external supply plenum from adequate roof or ceiling
supports.
2. The external supply plenum should be resting lightly against
the hood. The hood is used to position the plenum only, it is
not intended to support the plenum. All hanger brackets must
be used and the plenum must be properly supported while
lifting to prevent damage or distortion. The supply plenum
must be hung level to operate properly.
(Optional fastening of supply plenum to hood. See directions
ATTACHED AIR CURTAIN CANOPY STYLE HOOD
below).
3. It is recommended that caulk be applied at the mating seams
and surfaces of the plenum, the hood, and the wall. If the
supply plenum is next to a wall, you will also need to caulk
around the surface next to the wall. Caulk the joints with NSF
Approved silicone caulk (GE SCS1009, or its equivalent). The
caulk is not provided.

Installing the Supply Duct Collar to the Plenum

1. Place the duct collar(s) over the opening, fastening with tack-
welds at 1 to 2 in. (2.54 to 5.08 cm) intervals, or sheet metal
screws at 3 to 6 in. (7.62 to 15.24 cm) intervals.
