• These fasteners are to help maintain the location of the Backsupply, and are not intended to hold the weight
of the Backsupply Unit.
• The fasteners should not interfere with the removable air diffusers.
• The 31.25 in. height is based upon the canopy hood hanging height of 78 in. from the finished floor to the
bottom of the hood.

to the backsupply.
Hanging the Backsupply Plenum
5. Hang the Backsupply Plenum from the ceiling.
(The Backsupply Plenum needs to be mounted 31.25 in. above the floor (based upon a canopy hood that will
be hung at 6 ft. 6 in. above the finished floor. This is measured from the lowest rear edge of the Backsupply
Plenum to the finished floor. Leave 6 to 10 inches of space below the plenum for access to the air diffusers.)
6. Fasten the Backsupply to the wall, going through the lower Backsupply wall. (See Fig. 12)
INSTALLATION INSTRUCTIONS FOR THE BACKSUPPLY PLENUM BSP
Installing the Supply Duct Collar
1. Find the center of the Backsupply Plenum.
2. If the Backsupply Plenum is less than 9 ft. 10 in. wide, cut opening at
the suggested location, centering the opening over the center of the
backsupply Plenum. (see Fig. 10A)
3. If the Backsupply Plenum is greater than 9 ft. 10 in. wide, divide the
width of the backsupply by four. This will give you the center of each
half. Cut openings at the suggested location, centering the duct collar
over the center measurement of each half. (see Fig. 10B)
4. Place the duct collar(s) over the opening, fastening with screws or tack
welds every four to six inches. (see Fig. 11)
