•
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 4" (10.2 cm) laundry-type wall caps.
•
Use metal vent only. Rigid metal vent is recommended.
Do
not use plastic or metal foil vent.
•
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.
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.
•
Use clamps to seal all joints in the vent system.
•
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. 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.
The specified
CFM varies from locale to locale. Consult your
HVAC professional for specific requirements
in your area.
Venting Methods
This range 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.
For non-vented
(recirculating)
installations
If it is not possible to vent cooking fumes and vapors to the
outside, the hood can be used in the non-vented
(recirculating)
version, fitting an activated carbon filter and the deflector. Fumes
and vapors are recycled through the top grille.

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.

Makeup
air
Local building codes may require the use of makeup air systems
when using ventilation systems greater than specified CFM of air
movement.
Maximum equivalent vent length is 35 ft (10.7 m).
