Venting requirements

Venting system must terminate to the
outside.
Do not terminate the vent in an attic or
other enclosed space.
Do not use four-inch laundry-type wall caps.
Do not use plastic vent.
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.
This range hood can be vented to the
outside ONLY.
Determine which outside venting method
needs to be used.
The length of the vent system and number
of elbows should be kept to a minimum to
provide efficient performance. The size of
the vent system should be uniform. Do Not
install two elbows together. Use duct tape
to seal all joints in vent system. Vent system
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 be vented
vertically through the roof through 7" round
vent system.
Figures 1-2 show common venting methods
and what types of materials are needed.

Recommended vent system length
Maximum length of vent system is 26 feet.
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 system piece used in the
system. See the following example.
