Advance planning
Determine the exact location of the vent hood.
•
Locate the template packed with the literature.
•
Plan the route for venting exhaust to the outdoors.
•
Use the shortest and straightest duct route possible. For satisfactory performance duct run should not exceed
•
100' equivalent length for any duct configurations.
Refer to "Duct Fittings" chart to compute the maximum permissible length for duct runs to the outdoors.
•
Use 8" round metal ductwork only.
•
Installation will be easier if the vent hood is installed before the cook-top and countertop are installed.

Ceiling Support Structures
• At the hood location, install 2"x 4" cross framing
between ceiling joists as shown. (2"x 4" 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.
