Installation Preparation
Plan the Location of the Hood and Ductwork
Use a plumb bob to check the location.
The countertop/cooktop below the hood
must be centered with the hood.
The hood should extend beyond the front and rear
edge of the cooking appliance.
The duct in the ceiling must be centered over
the cooktop.

Ceiling Support Structure
At the hood location, install cross-framing between
ceiling joists as shown. (2x4 wood supports
are required to support the weight of the hood.)
Arrange cross-framing in the ceiling to suit
the existing structure.
Your ceiling joists will be like one of the following
examples.
