■

Flexible vent is not recommended. Flexible vent 

creates both back pressure and air turbulence 

that greatly reduce performance.

 

■

The vent system is optional for this model.

Vent system can terminate either through the roof or wall.

4

" x 10" (8.3 x 25.4 cm) rectangular with a maximum 

vent length of 35 ft (10.7 m).

An additional backdraft damper should be installed to 

minimize backward cold air flow and a thermal break should 

be installed to minimize conduction of outside temperatures 

as part of the vent system. The damper should be on the cold 

air side of the thermal break.
The break should be as close as possible to where the 

vent system enters the heated portion of the house.

Local building codes may require the use of makeup 

air systems when using ventilation systems greater than 

specified CFM of air movement. The specified CFM varies 

from locale to locale. Consult your HVAC professional 

for specific requirements in your area.

 

■

Vent system must terminate to the outdoors, except  

for non-vented (recirculating) installations.

 

■

Do not terminate the vent system in an attic 

or other enclosed area.

" x 10" (8.3 x 25.4 cm) rectangular metal 

vent, depending on your installation requirement. 

Rigid metal vent is recommended. Plastic or metal 

foil vent is not recommended.

 

■

The length of vent system and number of elbows should 

be kept to a minimum to provide efficient performance.

 

■

Use no more than three 90° elbows.

 

■

Make sure there is a minimum of 24" (61 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.
