DUCT FITTINGS

Hoods Are Equipped
For 10" Round Duct
Use this chart to compute maximum
permissible lengths for duct runs to
outdoors.
NOTE: Do not exceed maximum
permissible equivalent lengths!
Maximum recommended duct
length for these hoods: 150 feet
Flexible ducting:
If flexible metal ducting is used,
all the equivalent feet values in
the table should 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
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.

length of duct pieces are based on actual tests conducted by
GE Appliances Evaluation Engineering and reflect requirements for
good venting performance with any ventilation hood.
