Installation Clearances
Venting Requirements
■ Vent system must terminate to the outside, except for the
recirculating installation.
■ 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 6" (15.2 cm) metal vent only. Rigid metal vent is
recommended. Do not use plastic or metal foil vent.
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 one elbow is used.
■ Do not install two elbows together.
■ Use duct tape to seal all joints in the vent system.
■ Use caulking to seal exterior wall or roof opening around
the cap.
Cold weather installations
An additional backdraft damper should be installed to minimize
backward cold air flow and a nonmetallic thermal break 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.
Make-up 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.
Venting Methods
This 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 reduces
performance.
Vent system can terminate either through the roof or wall. To vent
through a wall, a 90° elbow is needed.
A 6" (15.2 cm) round vent system length should not exceed
35 feet (10.7 m).
For recirculating installations see “Recirculating Installations” in
“Install Chimney Covers” section.

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 No.
4396913 (Stainless Steel) or Kit No. 4396914 (Meteorite) 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' 7
¹⁄₈" (2.31 m) and 9' 1³⁄₄" (2.79 m).
For recirculating installations, the chimney can be adjusted for
ceilings between 8' 3
³⁄₈" (2.52 m) and 9' 5¹⁄₄" (2.88 m).
