min.
An 8" (20.3 cm) round vent system is needed for installation (not included). The hood exhaust opening is 8" (20.3 cm) round.
Vent system can terminate either through the roof or wall. To vent through a wall, a 90° elbow is needed.

Do not use 4" (10.2 cm)
Use 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.

Calculating Vent System Length
To calculate the length of the system you need, add the equivalent feet (meters) for each vent piece used in the system.
