*For non-vented (recirculating) installations
IMPORTANT:
Minimum distance "X": 18" (45.7 cm) from electric cooking
surface.
Minimum distance "X": 22" (55.9 cm) from gas cooking
surfaces.
Suggested maximum distance "X": 24" (61.0 cm)
For vented installations, the chimneys can be adjusted for
ceilings between 7’ 11" (2.4 m) and 9' 3" (2.8 m).
For non-vented (recirculating) installations, the chimneys can
be adjusted for ceilings between 7’ 11" (2.4 m) and 9' 7" (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 Chimney Extension Kit
Part Number W10272075 (stainless) or W10272074 (white) is
available from your dealer or an authorized parts distributor. The
chimney extension replaces the upper chimney shipped with the
range hood.
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 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 back draft damper should be installed to minimize
backward cold air flow. 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.
Venting Methods
This range hood is factory set for 8" (20.3 cm) round venting
through the roof or wall. An 8" (20.3 cm) round vent system is
needed for installation (not included). To vent through the wall, a
90° elbow is needed.
This range hood can also be set for 3¼" x 10" (8.3 x 25.4 cm)
rectangular venting out the back using the 3¼" x 10" (8.3 x
25.4 cm) rectangular damper (supplied). See the “Connect Vent
System” section for details for installing the damper and vent
system.
NOTE: Flexible vent is not recommended. Flexible vent creates
back pressure and air turbulence that greatly reduce
performance.
NOTE: This hood can be installed without the chimney covers
when venting directly out the back or when using the recirculation
kit with the top grill cap. See “For non-vented (recirculating)
installations without vent only:” section.
