Hanging the Hood with Back Supply Plenum

Before hanging the hood according to the hood installation instructions, please check the following:

1. Make sure the back supply unit is properly secured, as described in steps 5 and 6, page 8.

2. Any filler panels should be attached to the hood before the hood installation.

To hang the hood:

1. Lift the hood and position it so the top of the hood is even with the back supply (Fig. 13). This height should correspond to the UL hanging height of the hood.

2. After the hood is hung from the ceiling, a hood mounting flange may be fastened to the back supply using sheet metal screws (by others).

Pilot holes are recommended.

3.Connect the remaining ductwork for the back supply and the hood. Caulk all mating seams and surfaces of the back supply, the hood, and

the wall.

Hood Mounting Instructions

Fig. 14 shows the locations where the hood must be fastened. If a Back Supply Plenum is part of the hood system, please see pages 8-9, Back Supply Plenum/Hood Installation.

To hang the hood:

1)Locate the studs in the wall.

2)Drill 1/2 in. (13 mm) diameter holes in the hood mouting flange. Be sure to align to wall studs.

3)Lift hood into a level position and lag bolt hood to wall (fasteners by others).

4)Bolt 1/2 in. (13 mm) threaded rod into the hanger brackets.

5)Fasten threaded rod to ceiling supports then level the hood.
