*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

25.4cm) 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.
