ELECTRICAL REQUIREMENTS
Observe all governing codes and ordinances. Ensure that the electrical installation
is adequate and in conformance with the National Electrical Codes, ANSI/NFPA 70
(latest edition), or CSA Standards C22.1-94, Canadian Electrical Code, Part 1 and
C22.2 No. 0-M91 (latest edition), all local codes, and ordinances. If codes permit
and a separate ground wire is used, it is recommended that a qualified electrician
determine that the ground path is adequate.
A copy of the above code standards can be obtained from:

†
120 volt, 60 Hz, AC only.
†
If the house has aluminum wiring, follow the procedure below:
o Connect a section of solid copper wire to the pigtail leads.
o Connect the aluminum wiring to the copper wire using special connectors
and/or tools designed and UL listed for joining copper to aluminum. Follow
the manufacturer's recommended procedure for the electrical connector.
Aluminum/copper connection must conform to local codes and industry
accepted wiring practice.
†
Wire sizes and connections must conform to the rating of the appliance as
specified on the model/serial rating plate. The model/serial plate is located
behind the filter on the rear wall of the range hood.
†
Wire sizes must conform to the requirements of the National Electrical Code,
ANSI/NFPA 70 (latest edition), or CSA Standards C22. 1-94, Canadian Electrical
Code, Part 1 and C22.2 No. 0-M91 (latest edition) and all local codes and
ordinances.
LOCATION REQUIREMENTS
VENTILATION REQUIREMENTS
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 state to state. Consult your HVAC professional for specific
requirements in your area.
Venting Method
To vent through a wall, a 90-degree elbow is needed. If exhaust ducting with a
diameter of less than 5.91” (150 mm) or if flat ducting is used, the noise level of the
range hood could increase and extraction will be less efficient.
Cold Weather Installations
An additional back draft 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 break should be as close as possible to where the vent
system enters the heated portion of the house.
For the most efficient and quiet operation
†
Use no more than three 90-degree elbow.
†
Make sure there is a minimum of 24” (61 cm) of straight duct between the
elbows if more than one elbow is used.
†
Do not install two elbows together.
†
Use clamps and tape 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 walls or roof openings around the cap.
†
The size of the vents should be uniform.
General requirements
†
Range hoods must be ventilated to the outdoors, except for non-vented
(recirculating) installations.
†
Do not ventilate the range hood into an attic or other enclosed areas.
†
Do not use 4” (10.2 cm) laundry-type wall caps.
†
The length of the range hood and the number of elbows should be kept to a
minimum to provide maximum performance.
Rear Discharge
A 90-degree elbow may be installed immediately above the hood.
IMPORTANT: Observe all governing codes and ordinances. Have a qualified
technician install the range hood. It is the installer's responsibility to comply
with installation clearances specified on the model/serial rating plate. Canopy
hood's location should be away from strong draft areas, such as windows, doors,
and strong heating vents. Cabinet opening dimensions that are shown must be
used. Given dimensions provide minimum clearance.
