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.

7" (17.8 cm) Round Vent System

Vent Piece		Round
45° elbow		2.5 ft
		(0.8 m)
90° elbow		5.0 ft
		(1.5 m)
7" (17.8 cm) wall cap		0.0 ft
		(0.0 m)
3¹⁄₄" x 10" (8.3 cm x 25.4 cm)		4.5 ft
to 7" (17.8 cm)		(1.4 m)
3¹⁄₄" x 10" (8.3 cm x 25.4 cm)		5.0 ft
to 7" (17.8 cm) 90° elbow		(1.5 m)
Example vent system
7" (17.8 cm) round				Wall cap
90˚ elbow
		6 ft (1.8 m)
	2 ft (0.6 m)
Maximum Recommended Length			= 50 ft (15.2 m)
1 - 90° elbow			= 5.0 ft (1.5 m)
1 - wall cap			= 0.0 ft (0.0 m)
8 ft (2.4 m) straight			= 8.0 ft (2.4 m)
Length of 7" (17.8 cm) system			= 13.0 ft (3.9 m)

3¹⁄₄" x 10" (8.3 cm x 25.4 cm)		5.0 ft
90° elbow		(1.5 m)
3¹⁄₄" x 10" (8.3 cm x 25.4 cm)		12.0 ft
flat elbow		(3.7 m)
3¹⁄₄" x 10" (8.3 cm x 25.4 cm)		0.0 ft
wall cap		(0.0 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 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:

■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 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.
