7 Kitchen Hoods • Type I and Type II
Installing External Supply Plenums
Using the Supply Plenum Clip
1. Fasten the hanging clip to the
supply plenum. Two clips are
needed for plenums less than
96 in. (243.84 cm) long and
three for plenums greater than
96 in. (243.84 cm). The third
clip is located in the center
of the plenum length. If there is a cabinet, the clip
should be 23.5 in. (59.69 cm) from the outside edge
of the cabinet.
2. Using the c-clamps provided, clamp the supply
plenum hanging clip to the hood standing seam.
Option: Drill and bolt a 1/4-20 SS bolt through the
clip and hood standing seam.
Using the Uni-strut
The uni-strut (supplied by others) supporting the hood,
may be cantilevered over the end of the hood and used
to mount to the hanger brackets on the supply plenums.
Using Hanger Brackets and Threaded Rod
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.
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
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.
Supply Plenum Clip
NOTE
The supply plenum is provided with plenum clips that
assist in hanging the plenum. Do not hang plenums
using only the clips. Threaded rod or uni-strut must
also be used.
