Cold weather installations

An additional back draft damper should be installed to minimize backward cold air flow and 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 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

Vent system can terminate either through the roof or wall. Use 3¹⁄₄" x 10" (8.3 x 25.4 cm) with a maximum recommended vent length of 35 ft (10.7 m) or 6" (15.2 cm) round vent with a maximum length of 50 ft (15.2 m) for vent system.

NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that gently reduces performance.

Venting Requirements

(Vented Models Only)

■Vent system must terminate to the outdoors, except for non- vented (recirculating) installations.

■Do not terminate the vent system in an attic or other enclosed area.

■Do not use a 4" (10.2 cm) laundry-type wall cap.

■Use a 6" (15.2 cm) or a 3¹⁄₄" x 10" (8.3 x 25.4 cm) round metal vent. Rigid metal vent is recommended. Plastic or metal foil vent is not recommended.

■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 roof or wall cap has a damper, do not use damper supplied with the range hood.

■Use caulking to seal exterior wall or roof opening around the cap.
