Installing External Supply Plenum
1. Insert 1⁄2 in. 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 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 SCS-1009, 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 in. to 2 in. intervals, or sheet metal screws
at 3 in. to 6 in. intervals.
