NOTE: The range hood chimneys are adjustable and designed
to meet varying ceiling or soffit heights, depending on the
distance "X" between the bottom of the range hood and the
cooking surface. For higher ceilings, a Stainless Steel Chimney
Extension Kit is available from your dealer or an authorized parts
distributor. See "Assistance or Service" section to order.
The chimney extension replaces the upper chimney shipped with

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
Max. ceiling height
thermal break.
9' 2" (2.79 m)
The break should be as close as possible to where the vent
system enters the heated portion of the house.
9' 2" (2.79 m)
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.

Venting Methods
9' 6" (2.9 m)
This canopy hood is factory set for venting through the roof
or wall.
A 6" (15.2 cm) round vent system is needed for installation
(not included). The hood exhaust opening is 6" (15.2 cm) round.
NOTE: Flexible vent is not recommended. Flexible vent
creates back pressure and air turbulence that greatly
reduce performance.
Vent system can terminate either through the roof or wall.
To vent through a wall, a 90° elbow is needed.
Rear Discharge
A 90° elbow may be installed immediately above the hood.
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 4" (10.2 cm) laundry-type wall cap.
Use metal vent only. 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.
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 the roof or wall
cap has a damper, do not use the damper supplied with
the range hood.
Use caulking to seal exterior wall or roof opening
around the cap.
The size of the vent should be uniform.
