Hanging the Back Supply Plenum

5. Hang the back supply plenum from the ceiling.
• The back supply plenum needs to be mounted
31.25 in. (79.375 cm) above the finished floor. This
is measured from the lowest rear edge of the back
supply plenum to the finished floor.
• Hang using threaded rod placed through the hanger
brackets.
6. Fasten the back supply to the wall, going through the
lower back supply wall.
• These fasteners are to help maintain the location of
the back supply, and are not intended to hold the
weight of the back supply unit.
• The fasteners should not interfere with the
removable air diffusers

Hood Hanging Height

The hood hanging height is critical. Hanging the hood at
the incorrect height may significantly reduce the ability
of the hood to function properly and may be in violation
of codes. The hood hanging height, typically 78 in.
(198.12 cm) above the finished floor, is given on the
UL label located on the end panel on the inside of the
hood. The hood must be hung level to operate properly.
The grease trough is pitched to drain into the grease
container.
