Duct Fittings - XO XORI36S Manual De Utilización

DUCT FITTINGS:

This Hood Must Use an
6" Round Duct. It Can
Transition to 3-1/4" x
10" or 3-1/4" x 12" Duct.
Use this chart to compu-
te maximum permissible
lengths for duct runs to
outdoors.
NOTE: Do not exceed maxi-
mum permissible equivalent
lengths!
Maximum duct length:
100 feet for range ho-
ods.
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 in-
terruption of such naturally
vented systems, follow the
heating equipment manu-
facturer's guidelines and
safety standards such as
those published by NFPA.
