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 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 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 3

4
" 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.
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 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.
