NOTE
• If you choose the rear exhaust method (wall
venting or roof venting), be sure there is enough
clearance within the wall for the exhaust duct.
When Installing Venting
• Keep the length of the ductwork and the number
of elbows to a minimum to ventilate your oven
efficiently. See examples in next section.
• Keep the size of the ductwork the same.
• Do not install two elbows together.
• Use duct tape to seal all joints in the duct system.
• Use caulking to seal the exterior wall or roof
opening around the cap.
• After installation, check the outside hood
opening and operation.
• For the outside hood opening and size refer to
the upper cabinet template or rear wall
template.
NOTE
• The ductwork you need for outside ventilation is
not included with your oven. See the standard
ductwork fittings.
Standard Ductwork Fittings
If the existing duct is round, you must use a
rectangular-to-round adapter, with a rectangular
3" extension duct installed between the damper
assembly and the adapter to prevent the exhaust
damper from sticking.
Duct Length
The total length of the duct system, including
straight duct, elbows, transitions, and wall or roof
caps must not exceed 140 feet.
For best performance, do not use more than three
90 degree elbows, and keep the length as short as
possible.
Below are the standard fittings and their
equivalent length in feet.
To calculate the equivalent length of each duct
piece used, see the examples below.
3 1/4" x 10" to 6" transition = 5 ft
3 1/4" x 10" roof cap = 24 ft
3 1/4" x 10" 90° elbow = 25 ft
90° elbow = 10 ft
3 1/4" x 10" wall cap = 40 ft
45° elbow = 5 ft
3 1/4" x 10" flat elbow = 10 ft
