Venting Requirements

(Vented Models Only)
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.
Do not use a 4" (10.2 cm) laundry-type wall cap.
■
Use a 6" (15.2 cm) round metal vent or a 3¹⁄
■
(8.3 x 25.4 cm) rectangular metal vent. 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.

For the most efficient and quiet operation:
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 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.
Cold Weather Installations
An additional back draft 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.
Makeup Air
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.
Venting Methods
The vent system for venting out of the top of range hood
can be terminated either through the roof or wall. Use a
6" (15.2 cm) round vent. The vent system for venting out the
rear of the range hood must be terminated through the wall.
Use a 3¹⁄ " x 10" (8.3 x 25.4 cm) rectangular vent. For rear
4
venting the 3 / " x 10" (8.3 x 25.4 cm) rectangular damper and
1
4
motor mounting bracket is required. See "Rear Vent Connector
Installation" section.
NOTE: Flexible vent is not recommended. Flexible vent
creates back pressure and air turbulence that gently
reduces performance.
