Venting requirements

the outside.
Do not terminate the vent in an attic
or other enclosed space.
Do not use four-inch (10.2 cm)
laundry-type wall caps.
Do not use plastic vent.
Vent system needed for installation
is not included.
Determine which outside venting
method needs to be used. It is
recommended that the vent
system be installed before
installing the hood.
NOTE: If a non-vented
(recirculating) installation is
desired, follow instructions on
Page 5.
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
the 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
