Venting Requirements

(vented models only)
■ V ent system must terminate to the outdoors, except for non-
vented (recirculating) installations.
■ D o not terminate the vent system in an attic or other
enclosed area.
■ D o not use 4" (10.2 cm) laundry-type wall cap.
■ U se metal vent only. Rigid metal vent is recommended.
Plastic or metal foil vent is not recommended.
■ T he 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:
■ U se no more than three 90° elbows.
■ M ake sure there is a minimum of 24" (61 cm) of straight vent
between the elbows if more than 1 elbow is used.
■ D o not install 2 elbows together.
■ U se clamps to seal all joints in the vent system.
■ T he 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.
■ U se caulking to seal exterior wall or roof opening around
the cap.
■ T he 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
This canopy hood is factory set for venting through the roof or
wall.
A 6" (15.2 cm) round vent system is needed for installation (not
included). The hood exhaust opening is 6" (15.2 cm) round.
NOTE: Flexible vent is not recommended. Flexible vent
creates back pressure and air turbulence that greatly reduce
performance.
Vent system can terminate either through the roof or wall.
To vent through a wall, a 90° elbow is needed.
Rear Discharge
A 90° elbow may be installed immediately above the hood.
