Installation Dimensions
*NOTE: The range hood chimneys are adjustable and
designed to meet varying ceiling or soft heights depending
on the distance “X” between the bottom of the range hood
and the cooking surface. For higher ceilings, an Extension Kit
Part Number W10352733 is available from your dealer or an
authorized parts distributor. The chimney extension replaces the
upper chimney shipped with the range hood.
IMPORTANT:
Minimum distance “X”: 24" (61 cm) from electric cooking
surfaces
Minimum distance “X”: 30" (76.2 cm) from gas cooking
surfaces

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 4" (10.2 cm) laundry-type wall caps.
■ 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 efcient performance.
For the most efcient and quiet operation:
■ 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 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 back draft damper should be installed to minimize
backward cold air ow 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.
Venting Methods
Typical Internal Blower Motor System Venting Installations
A 10" (25.4 cm) round vent system is needed for installation (not
included). The range hood exhaust opening is 10" (25.4 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 the wall, a 90º elbow is needed.
