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

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.
Vent Piece | 6" (15.2 cm) Round |
45° elbow | 2.5 ft |
| (0.8 m) |
90° elbow | 5.0 ft |
| (1.5 m) |
Maximum equivalent vent length is 35 ft (10.7 m).

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
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

■A 120 Volt, 60 Hz., AC only,
■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 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.
