IMPORTANT:
Minimum distance “X”: 24" (61.0 cm) from electric
cooking surface
Minimum distance “X”: 27" (68.6 cm) from gas
cooking surface
Suggested maximum distance “X”: 36" (91.4 cm)
The chimneys can be adjusted for different ceiling heights.
See the following chart.
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. For higher ceilings, a Stainless Steel Chimney Extension
Kit Part Number W10294735 is available from your dealer or an
authorized parts distributor. The chimney extension replaces the
upper chimney shipped with the range hood.
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 cap.
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 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 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.
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 a charcoal 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.
Maximum equivalent vent length is 35 ft (10.7 m).
