Installation Clearances

NOTE: The hood chimneys are adjustable and designed to meet
varying ceiling or soffit heights depending on the distance “X”
between the bottom of the hood and the cooking surface. For
higher ceilings, a 40" (101.6 cm) Chimney Extension Kit Part
Number 8212698 (Black), Kit Part Number 8212696 (Stainless
Steel) or Kit Part Number 8212697 (White) is available. See your
dealer. The chimney extension replaces the upper chimney
shipped with the hood.
IMPORTANT:
Minimum distance “X”: 24" (61.0 cm)
Suggested maximum distance “X”: 30" (76.2 cm)
For vented installations, the chimneys can be adjusted for
ceilings between 7’ 7¹⁄₈" (2.31 m) and 9' 1³⁄₄" (2.79 m).
For non-vented (recirculating) installations, the chimney
can be adjusted for ceilings between 8' 3³⁄₈" (2.52 m) and
9' 5¹⁄₄" (2.88 m).
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 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 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.
■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 nonmetallic 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 island hood is factory set for venting through the roof or wall.
A 6" (15.2 cm) round vent system is needed for installation (not
included). The hood exhaust opening is 6" (15.2 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 wal l. To vent
through a wall, a 90° elbow is needed.
