Electrical Requirements:
● A 120 volt, 60 Hz., AC only, 15-amp, fused electrical circuit is
required.
● If the house has aluminum wiring, follow the procedure below:
1. Connect a section of solid copper wire to the pigtail
leads.
2. Connect the aluminum wiring to the added section
of copper wire using special connectors and/or
tools designed and UL listed for joining copper to
aluminum.
Follow the electrical connector manufacturer's recommended
procedure. Aluminum/copper connection must conform with local
codes and industry accepted wiring practices.
*For non-vented (recirculating) installations
IMPORTANT:
Minimum distance “X”: 24" (61.0 cm) from electric
cooking surface.
Minimum distance “X”: 27" (68.6 cm) from gas
cooking surfaces.
Suggested maximum distance “X”: 36" (91.4 cm)
The chimneys can be adjusted for different ceiling heights. See the
following chart.
Vented Installations
Min. ceiling height Max. ceiling height
Electric cooking surface 7' 1" (2.16 m) 9' 2" (2.79 m)
Gas cooking surface 7' 4" (2.23 m) 9' 2" (2.79 m)
Non-vented (recirculating) Installations
Min. ceiling height Max. ceiling height
Electric cooking surface 7' 1" (2.16 m) 9' 6" (2.9 m)
Gas cooking surface 7' 4" (2.23 m) 9' 6" (2.9 m)
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
W10272075 is available from your dealer or an authorized parts
distributor. The chimney extension replaces the chimney shipped with
the range hood.
PRODUCT DIMENSIONS
VENTING REQUIREMENTS
● 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" (61.0 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 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 make up 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.
