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

Recommended vent length
Use 3-1/4" x 10" or 6" vent. The total length of the vent system
including straight vent, elbow, transitions, wall or roof caps
must not exceed the equivalent of 140 feet of
3-1/4" x 10" rectangular or 6" diameter round vent. 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 examples below.
NOTE: There must be
at least one wall stud
within cabinet
opening.

CABINET OPENING DIMENSIONS
For wall or roof venting methods:
If the wall exhaust method is chosen, be sure that
there is proper clearance within the wall for the
exhaust vent.
Wall and roof caps must have back-draft damper.
We recommend:
✔ using rigid metal vent.
✔ that length of vent and number of elbows should
be kept to a minimum to provide efficient
performance.
✔ that size of vent should be uniform.
✔ using duct tape to seal all joints in the vent
system.
✔ using caulking compound to seal exterior wall or
roof opening around cap.
✔ two elbows should not be installed together.
We do NOT recommend:
✔ flexible metal vent.
NOTE: If flexible metal vent must be used, calculate
each foot of flexible metal vent as two feet of rigid
metal vent. Flexible metal elbows count twice as
much as standard elbows.
