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 Part Number W10337357 is available from your dealer or an
authorized parts distributor. The chimney extension replaces the
upper chimney shipped with the range hood.

Venting Requirements

(venting 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.
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 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.
■
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.
