If the existing duct is round, a rectangular­to-round adapter must be used and a
rectangular 3" extension duct between the
damper assembly and the adapter must be
installed to prevent sticking of the exhaust
damper.

Recommended duct length

Use 3-1/4" x 10" or 6" duct.The total length
of the duct system including straight duct,
elbow, transitions, wall or roof caps must
not exceed the equivalent of 140 feet of 3­1/4" x 10" rectangular or 6" diameter round
duct. For best performance, use no more
than three 90° elbows.To calculate the
length of system you need, add the
equivalent feet for each duct piece used in
the system. See examples at right.

Use metal ductwork only. Rigid metal
ductwork is recommended.

Flexible metal ductwork is Not recommended.
If flexible metal ductwork 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.

Determine which venting method (roof-venting
or wall-venting) you need to use.
This microwave oven hood is equipped for
ventless (recirculating) installation.

The length of the ductwork and number of
elbows should be kept to a minimum to
provide efficient performance.The size of
ductwork should be uniform. Do Not install
two elbows together.Use duct tape to seal all
joints in the duct system. Use caulking to seal
exterior wall or roof opening around cap.
