• Vent system must terminate to the outside, 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 caps,
• Use a metal vent only, A rigid metal vent is recommended, Do
not use plastic or metal foil vent.
• The size of the vent should be uniform.
• 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 2 elbows together.
• The length of vent system and number of elbows should be
kept to a minimum to provide efficient performance,
• 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 clamps to seal all joints in the vent system.
• Use caulking to seal exterior wall or roof opening around the
cap.
• Determine which venting method is best for your application.
Cold weather installations
An additional back draft damper should be installed to minimize
backward cold air flow and a nonmetallic 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.
