Before hanging the hood according to the
hood installation instructions, please check the
following:
1. Make sure the back supply plenum is
properly secured, as described in steps 5
and 6, page 10.
. If the ductwork for the back supply will not
interfere with the hood installation, it should
be connected now.
3. Any filler panels should be attached to the
hood before the hood installation.
See page 5 for instructions.
4. Lift the hood, and position it so the filler
panels are resting lightly on the top outside

intended to hold any hood weight. (Fig. 16)
5. Connect the remaining ductwork for the
back supply and the hood. It is recommended
that caulk be applied at the mating seams
and surfaces of the back supply, the hood,
and the wall.
