For vented models:

Vent system requirements

Do not terminate the vent system in an attic or other enclosed area.

Do not use 4" (10.2 cm) laundry- type wall caps.

Use metal vent only. Rigid metal vent is recommended. Do not use plastic or metal foil vent.

Flexible vent is not recommended. Flexible vent creates back pressure that greatly reduces the hood's performance.

• The size of the vent should be

uniform.

• 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 one elbow is used.

• Do Not install two elbows

together.

• The length of vent system and

number of elbows should be

kept to a minimum to provide

efficient performance.

• 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 duct tape to seal all joints

in the vent system.
