Do Not terminate the ductwork in
an attic or other enclosed space.
l
Do Not use 4" laundry-type
wall
caps.
l
Do Not use plastic-type
ductwork.
Failure to follow recommended
venting instructions may result in a
fire.
CAUTION: To reduce risk of fire and to
properly exhaust air, be sure to duct
air outside. - Do Not vent exhaust air
into spaces within walls or ceilings or
into attics, crawl spaces or garages.
Ductwork needed for installation is not
included. Backdraft damper supplied
with product must be properly installed.
If roof or wall cap has a damper, Do Not
use damper supplied with hood.
Determine
which
outside
venting
method
needs to be used.
The length
of the ductwork
and number
of elbows
should be kept at o minimum
to provide
efficient
performance.
The
size of the ductwork
should be uniform.
Do Not install two elbows together.
Use
ductwork
system. Ductwork
can
terminate
either thought
the roof or wall.
Use caulking
to seal exterior
wall or roof
opening
around
exhaust
hood,
For the
most efficient
and quiet operation,
it is
recommended
that the range hood be
vented
vertically
through
the roof
through
7" round ductwork.
Flexible metal ductwork is Not
recommended.
If it is used, calculate
each foot of flexible
metal ductwork
as
two feet of straight
metal ductwork.
Flexible metal elbows
count
twice
as
much as standard
elbows.
Use metal
ductwork
only.
Figures l-4 show common
venting
methods
and what types of materials
are needed.

length
Use 3- l/4" x 10" or 7" ductwork
with
a maximum
length
of 26 feet
for ductwork

For best
performance.
use no more than
three 90" elbows.
To calculate
the
length of system you need, odd the
equivalent
feet for each ductwork
piece used in the system.
