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.

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).

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.
