IMPORTANT:
Minimum distance “C”: 24" (61.0 cm) from electric cooking
surface.
Minimum distance “C”: 27" (68.6 cm) from gas cooking
surface.
Suggested maximum distance “C”: 36" (91.4 cm)
The chimneys can be adjusted for different ceiling heights. See
the following chart.

*NOTE: The range hood chimneys are adjustable and designed
to meet varying ceiling or soft heights, depending on the
distance “C” between the bottom of the range hood and the
cooking surface. For higher ceilings, a Chimney Extension Kit is
available from your dealer or an authorized parts distributor. The
chimney extension replaces the upper chimney shipped with the
range hood. To order, see the “Assistance or Service” section.
Venting Requirements
■ Vent system must terminate to the outside, 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 caps.
■ Use metal vent only. Rigid metal vent is recommended. Do
not use plastic or metal foil vent.
■ 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.
For the Most Efcient and Quiet Operation:
■ Use a straight run or as few elbows as possible.
■ Use no more than three 90° elbows.
■ Make sure there is a minimum of 24" (61.0 cm) of straight
vent between the elbows, if more than 1 elbow is used.
■ Do not install 2 elbows together.
■ Use vent clamps to seal all joints in the vent system.
■ 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 back draft damper should be installed to minimize
backward cold airow 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 specied CFM of air
movement. The specied CFM varies from locale to locale.
Consult your HVAC professional for specic requirements in your
area.
