1. Insert 1/2 in. (12.7 mm) diameter threaded rod (by
others) into hanger brackets on the external supply
plenum top. Raise and hang the external supply
plenum from adequate roof or ceiling supports.
3. It is recommended that caulk be applied at the
mating seams and surfaces of the external supply
plenum, the hood, and the wall. If the external supply
plenum is next to a wall, you will 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. It is suggested that the duct collar be attached
to the supply plenum before installing the supply
plenum.
2. The external supply plenum should be resting
lightly against the hood. The hood is only used to
position the plenum; it is not intended to support the
plenum. All hanger brackets on the external supply
plenum must be used and the plenum must be
properly supported while lifting to prevent damage or
distortion. The external supply plenum must be level
to operate properly.
NOTE
Ensure the external supply plenum is installed
flush with the hood front and is plumb and level by
adjusting the threaded rod(s). There should be no gap
between the bottom of the external supply plenum
and the hood after installation and adjustments are
completed.
NOTE
After hanging, secure the external supply plenum to
the hood (or to another external supply plenum) using
the supplied turnbuckle(s). Use caution tensioning the
turnbuckle. Too much tension may cause the bottom
of the external supply plenum to pull away from
the hood or cause the face of the hood to become
deformed.
