Grounding Instruction
WARNING: The improper connection of the equipment-grounding conductor can result in a risk of electric
shock. Check with a qualified electrician if you are in doubt whether the appliance is properly grounded.
The grounding conductor must be connected to a metal ground, permanent wiring system, or an
equipment-grounding terminal or lead on the hood.
Exhaust Ducting
The hood uses 6-inch metal ducting to exhaust fumes. Refer to the vent hood installation instructions for
details of the maximum permissable lengths to be used for duct runs to outdoors. Do not exceed the
maximum permissable equivalent length total of 100 feet for a range hood.
Flexible 6-inch metal ducting may be used. When flexible ducting is used, all equivalent feet values of
components must be doubled. The flexible metal duct should be straight and smooth and extended as
much as possible. Do not use flexible plastic ducting.
Note: Any home ventilation system, such as a ventilation hood, may interrupt the proper flow of combus-
tion air and exhaust required by fireplaces, gas furnaces, gas water heaters, and other naturally vented
systems. To minimize the chance of interruption of such naturally vented systems, follow the heating
equipment manufacturer's guidelines and safety standards such as those published by NFPA and ASHRAE.
Install all ductwork by making joint connections
in the direction of the air flow as illustrated.
Secure the joints with sheetmetal screws. Wrap
the joints with duct tape for an airtight seal.
