VENTING REQUIREMENTS
●
Vent system must terminate to the outdoors.
●
Do not terminate the vent system in an attic or other enclosed area.
●
Do not use a 4" (10.2 cm) laundry-type wall cap.
●
Use metal vent only. Rigid metal vent is recommended.
●
The length of vent system and number of elbows should be kept to a
minimum to provide efficient performance.
For the most efficient and quiet operation:
●
Use no more than three 90° elbows.
●
Make sure there is a minimum of 24" (61.0 cm) of straight vent
between the elbows if more than 1 elbow is used.
●
Do not install 2 elbows together.
●
Use clamps or duct tape to seal all joints in the vent system.
●
The vent system must have a damper. If roof or wall cap has a
damper, do not use damper supplied with the range hood.
●
Use caulking to seal exterior wall or roof opening around the cap.
●
The size of the vent should be uniform.
Venting Methods
This canopy hood is factory set for venting through the roof or wall.
A 3¹⁄₄" x 10" (8.3 cm x 25.4 cm) rectangular vent system is needed for
installation (not included). The hood exhaust opening is 3¹⁄₄" x 10"
(8.3 cm x 25.4 cm). Vent system can terminate either through the roof
or wall. To vent out of the top of the range hood and through a wall, a
90° elbow is needed. See “Install Range Hood” section for details for
installing the damper.
NOTE: Flexible vent is not recommended. Flexible vent creates back
pressure and air turbulence that greatly reduce performance.
Rear discharge
This range hood can be vented directly out the back using the 3¹⁄₄" x 10"
(8.3 cm x 25.4 cm) rectangular damper (supplied) along with a 3¹⁄₄" x
10" (8.3 cm x 25.4 cm) rectangular vent system (not supplied). See
“Install Range Hood” section for details for installing the damper.

Calculating Vent System Length
To calculate the length of the system you need, add the equivalent feet
(meters) for each vent piece used in the system.
