Fig. 10
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 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.
