Recommended standard fittings
If the existing vent is round, a rectangular-
to-round adapter must be used and a
minimum 3" (7.6 cm) clearance must exist
between the top of the microwave oven and
the rectangular to round transition piece so
that the damper can open freely and fully.

Recommended vent length
A 3-¹⁄₄" x 10" (8.3 x 24.5 cm) rectangular or 6" (15.2 cm)
round vent should be used. The total length of the vent
system including straight vent, elbow, transitions, wall or
roof caps must not exceed the equivalent of 140 feet
(42.7 m) for either type of 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.
