Recommended standard fittings
If the existing vent is round, a rectangularto-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.

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 so the vent
fits properly and the damper blade opens fully.
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.
NOTE: The grounded 3 prong outlet
must be inside the upper cabinet.
