• The 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 vent or wall caps.
• Use round, metal vent only. Rigid metal vent is
recommended. Plastic or metal foil vent is not
recommended.
• The length of the 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" (61.0 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.
• Use weatherproof caulking to seal the exterior wall or roof
opening around the cap.
• The size of the vent should be uniform.
Cold weather installations
An additional backdraft damper should be installed to
minimize backward cold air flow. 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 thermal break should be as close as possible to where the
vent system enters the heated portion of the house.

NOTE: The minimun installation height recommended for
the external blower kit is 40" (102 cm) from the floor to the
center of the round vent system.
Typical External Blower System Installations
A 8" (20.32 cm) - 10" (25.4 cm) round vent system is needed
for installation (not included). The external blower system
inlet and outlet openings are 8" (20.32 cm) - 10" (25.4 cm)
round. The exhaust (outlet) opening on the range hood must
also at leat 8" (25.4 cm) round.
NOTE: Flexible vent is not recommended. Flexible vent
creates back pressure and air turbulence that greatly reduce
performance.
The vent system can terminate either through the wall.
NOTE: Plywood may be used as a mounting base to span
open areas between ceiling joists and rafters. If used, be
sure to use plywood capable of supporting the weight of the
external blower system (83 lb [37.5 kg]).
