9. Choose Venting Option
The hood can be set to vent outside or to
recirculate air back into the kitchen.
The plastic vent lever is located near the center
of the hood opening.
To vent to the outside, make sure the plastic
vent lever is in the HORIZONTAL position (flat
against the metal top of the hood).
To recirculate air into the kitchen, make sure
the plastic vent lever is in the VERTICAL
position (flat against the plastic blower housing).
NOTE: In order to change the vent lever
position, you will need to pull the lever out
slightly to clear the plastic tabs.
10.For recessed bottom cabinet only
If the cabinets have front, side or back trim,
make 2 wood shims the width of the trim and
attach them to the cabinet bottom recess on
both sides. See previous page for marking
locations.
11.Cut holes at marked locations for duct and
electrical wiring. For the vertical duct, cut out 3/
4” extra toward the front of the cabinet so you
can move the duct freely when installing the
hood.
It may also ease installation by cutting the hole
10 1/2” instead of 10”.
12.Drive a mounting screw (from the hardware
packet) partway into each center of the narrow
neck of the keyhole slots marked on the cabinet
bottom.
13.Fix the wiring conduit to the hood.
14.Slide the hood back against the wall. Tighten
the mounting screws. Be sure the screw heads
are in the narrow neck of the keyhole slot.
Connect Ductwork to hood.
