If the existing vent is round, a rectangular-
to-round adapter must be used and a
rectangular 3" (7.6 cm) extension vent
between the damper assembly and the
adapter must be installed to prevent sticking
of the exhaust damper.

OVERALL DIMENSIONS
CABINET OPENING DIMENSIONS
NOTE: The grounded 3 prong outlet
must be inside the upper cabinet. See
"Electrical Requirements" section.
NOTE: There must be at least one 2" x 4"
(50.8 cm x 101.6 cm) wall stud and
minimum 3/8" (9.5 mm) thickness
drywall or plaster/lath within cabinet
opening. Must be able to support
150 lbs. (68 kg).
* 30" (76.2 cm) is typical for
66" (167.6 cm) installation height.
Exact dimensions may vary
depending on type of
range/cooktop installed below.
Wall venting
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
damper to fully open.
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
3-1/4" x 10"
performance.
90° elbow = 25 ft.
✔ 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.
3-1/4" x 10"
90° flat
elbow= 10 ft.
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.

Recommended vent length
Use 3-1/4" x 10" (8.3 cm x 25.4 cm) rectangular or 6" (15.2 cm)
round vent. The total length of the vent system including
straight vent, elbow(s), transitions, wall or roof caps must not
exceed the equivalent of 140 feet (42.7 m) of 3-1/4" x 10"
(8.3 cm x 25.4 cm) rectangular or 6" (15.2 cm) 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.
