Venting Requirements
■ This range hood is factory set to exhaust the air to
the outside through the wall or the roof. A non-vented
(recirculating) installation will require a Charcoal Filter Kit.
See the “Accessories” section for ordering information.
■ Vent system must terminate to the outdoors, except for
nonvented (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 7" (17.8 cm) round metal vent or a 3¹⁄
4
" x 10"
(8.3 cm x 25.4 cm) rectangular metal vent, depending
on your installation requirements. 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.
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
Vent system can terminate either through the roof or wall. Use
3¹⁄
4
" x 10" (8.3 cm x 25.4 cm) rectangular with a maximum vent
length of 35 ft (10.7 m) or 7" (17.8 cm) or larger round vent with
a maximum length of 50 ft (15.2 m) for vent system.
NOTE: Flexible vent is not recommended. Flexible vent creates
both back pressure and air turbulence that greatly reduce
performance.
