Installation Preparation

36" Island Vent Hood

Step1

Advance Planning

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.

Typical Support Frame Mounting

*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.

Ceiling support structure

•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.
