Advance
Planning

Step
Note:
The cross framing
must be spaced 8-3/4” on
the side from centerline to
centerline in order to
accept the hood mounting
screws.
Plan the location
Determine the exact location of the vent hood.
• Use a plumb to check location to be sure
countertop/cooktop location below the hood
will align exactly.
• The hood should project forward 1-1/2”
beyond the front edge of the cooking appli-
ance. See illustration.
• Observe the recommended 25-1/2" space
between the cooking surface and bottom of
hood.

• At the hood location, install 2 x 4 cross
framing between ceiling joists as shown.
• The 2 x 4 cross framing can be installed
standing or flat, depending on duct run.
See illustration of ductwork, page 7.
*The framing should be spaced 8-3/4” on the sides and 7-5/8" at
the front from centerline to centerline to accept mounting screws
in the vent support frame.
