Installation Instruction

Room Venting

Oven is located on an inside wall of house.

Room Venting

NOTE: Remember the following when installing venting.

•Keep length of ductwork and the number of elbows to a minimum to ventilate oven efficiently.

•Keep the size of the ductwork the same.

•Do not install two elbows together.

•Use duct tape to seal all joints in the ductwork system.

•Use caulking to seal exterior wall or roof opening around the cap.

Standard Fittings

NOTE: If existing ductwork is round, a rectangular-to- round adapter must be used with a rectangular 3" extension duct installed between the damper assembly and adapter to prevent the exhaust damper from sticking.

Ductwork Length

The total length of the ductwork system, including straight duct, elbows, transitions, and wall or roof cap must not exceed the equivalent of 140 feet.

For best performance, do not use more than three 90° elbows and keep the length as short as possible.

Following are standard fittings and their equivalent length in feet.

To calculate the equivalent length of each duct piece used, see examples below.

For 3 1/4"x10" Systems
3 1/4"x10"	6ft.	wall cap
90 elbow
2ft.
1-3 1/4" x 10" 90 elbow		=	25 ft.
1-Wall Cap		=	40 ft.
8 feet straight duct		=	8 ft.
Total Length		=	73 ft.

For 6" Round Systems			wall cap
90 elbows		6ft.
transition	2ft.
1-transition		=	5 ft.
2-90 elbows		=	20 ft.
1-Wall Cap		=	40 ft.
8 feet straight		=	8 ft.
Total Length		=	73 ft.
