Electrical Requirements
Observe all governing codes and ordinances.
Ensure that the electrical installation is adequate and in conformance with 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.
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:
National Fire Protection Association
1 Batterymarch Park
Quincy, MA 02169-7471
CSA International
8501 East Pleasant Valley Road
Cleveland, OH 44131-5575
■■ A 120-volt, 60 Hz., AC-only, 15-amp, fused electrical circuit is required.
■■ If the house has aluminum wiring, follow the procedure below:
1.Connect a section of solid copper wire to the pigtail leads.
2.Connect the aluminum wiring to the added section of copper wire using special connectors and/or tools
designed and UL listed for joining copper to aluminum.
Follow the electrical connector manufacturer's recommended procedure. Aluminum/copper connection must conform with local codes and industry accepted wiring practices.
■■ Wire sizes and connections must conform with the rating of the appliance as specified on the model/serial/rating plate. The model/serial/rating plate is located on the front of the downdraft vent above the wiring box cover.
■■ 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.
Venting Requirements
IMPORTANT: Make sure there is proper clearance within the wall or floor before making exhaust vent cutouts.
■■ Use heavy (rigid) metal vent.
■■ Venting system must terminate to the outside.
■■ Do not terminate the vent system in an attic or other enclosed area.
■■ Do not use 4" (10.2 cm) laundry-type wall caps. ■■ Do not install 2 elbows together.
■■ Do not use plastic or metal foil vent.
■■ The length of vent system and number of elbows should be kept to a minimum to provide efficient performance.
■■ 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 one elbow is used.
■■ Use clamps or duct tape to seal all joints in the vent system.
■■ Use caulking tape to seal the exterior wall or floor opening around cap.
■■ Do not cut joist or stud. If vent cutout falls over a joist or stud, a supporting frame must be constructed.
Flexible metal vent is not recommended. If it is used, calculate each foot of flexible vent as 2 ft (0.6 m) of rigid metal vent.
Flexible elbows count twice as much as standard elbows.
Recommended vent system length:
For either interior-mounted or exterior-mounted blower installations, the vent system length should not exceed the maximum lengths listed in the “Maximum Length of Vent System” chart. See “Calculating Vent System Length” in the “Venting Methods” section in the Installation Instructions.
Cold Weather Installations
An additional backdraft damper should be installed to minimize backward cold airflow 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.
