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.

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).
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' 7¹⁄₈" (2.31 m) and 9' 1³⁄₄" (2.79 m).
For 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 the recirculating installation.
■Do not terminate the vent system in an attic or other enclosed area.
■Do not use 4" (10.2 cm)
■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.
For recirculating installations see “Recirculating Installations” in “Install Chimney Covers” section.
