DUCT FITTINGS

This Hood Must Use an
6 Round Duct. It Can
Use this chart to compute
maximum permissible lengths
for duct runs to outdoors.
NOTE: Do not exceed maximum
permissible equivalent lengths!
Maximum duct length:
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.
