Venting Requirements

Vent system must terminate to the outdoors.
Do not terminate the vent system in an attic or other enclosed
area.
Do not use 4" (10.2 cm) laundry-type wall cap.
Use metal vent only. Rigid metal vent is recommended.
Plastic or metal foil vent is not recommended.
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.
13" (33 cm)
cabinet depth
Use clamps to seal all joints in the vent system.
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.
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 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
Vent system can terminate either through the roof or wall. Use a
7" (17.8 cm) round vent with a maximum length of 26 ft (7.9 m) for
vent system.
