Venting System
Venting Methods
NOTES:
■ 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.

Cold Weather Installations
An additional backdraft damper should be installed to
minimizebackward cold air ow 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
speciedCFM of air movement. The specied CFM varies
fromlocale to locale. Consult your HVAC professional
forspecic requirements in your area.
Venting Requirements
■ 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 3

" 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 efcient performance.
For the most efcient 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 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.
