Installation Dimensions
*NOTE: The range hood chimneys are adjustable and designed 
to meet varying ceiling or soffit heights depending on the 
distance “X” between the bottom of the range hood and the 
cooking surface. The chimney extension replaces the upper 
chimney shipped with the range hood. See “Assistance or 
Service” section to order.
IMPORTANT:
Minimum distance “X”: 24" (61.0 cm)
Suggested maximum distance “X”: 36" (91.4 cm)
The chimneys can be adjusted for ceilings between 7'5" (2.26 m) 
with dimension “X” at 24" (61.0 cm) and 9' 8½" (2.96 m) with 
dimension “X” at 36" (91.4 cm).
Venting Requirements
(Vented Models Only)
Vent system must terminate to the outdoors, 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. 
Plastic or metal foil vent is not recommended.
The 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:
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. 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 make up 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 range hood is factory set for venting through the roof 
or through the 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) 
installation by fitting the charcoal filters and the diverter to the 
range hood. Fumes and vapors are recycled through the vent 
slots in the lower chimney.
