*NOTE: The range hood chimneys are adjustable and designed
to meet varying ceiling or soffit heights depending on the
distance "C" between the bottom of the range hood and the
cooking surface. For higher ceilings, a Stainless Steel Chimney
Extension Kit Part Number W10272078 is available from your
dealer or an authorized parts distributor. The chimney extension
replaces the chimney shipped with the range hood.
• 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 efficient 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 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.
