Vent system needed for installation is not
included. Backdraft damper supplied with
product must be used. If roof or wall cap
has a damper, do not use damper supplied
with hood. Use metal vent only. Rigid metal
vent is recommended.
Determine which outside venting method
you need to use.
The length of the vent and number of
elbows should be kept to a minimum to
provide efficient performance. The size of
the vent should be uniform. Do Not install
two elbows together. Use duct tape to seal
all joints in the vent system. Vent can
terminate either through 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 using 7"
round vent.
Figures 1-4 show common venting methods
and what types of materials are needed.
Recommended vent length
Use 3-1/4" x 10" or 7" vent with a maximum
length of 26 feet for vent system. For best
performance, use no more than three 90°
elbows. To calculate the length of system
you need, add the equivalent feet for
each vent piece used in the system. See
the following examples.
