Installation Preparation
This Hood Must Use an 8" Round Duct.
It Can Transition to a 3-1/4" x 12" Duct.
DO NOT use flexible plastic ducting.
NOTE: Any home ventilation system, such as a ventilation hood, may interrupt the proper flow
of combustion 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. When applicable, install any makeup (replacement) air system in accordance
with local building code requirements. Visit GEAppliances.com for available makeup air solutions.
