Whirlpool LI31HC/W10526058F Electrical Requirements, Venting Methods, Example Vent System

Venting Methods

This island hood is factory set for venting through the roof.

A 6" (15.2 cm) round vent system is needed for installation (not included). The hood exhaust opening is 6" (15.2 cm) round.

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.

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 non-vented (recirculating) version, fitting a charcoal filter and the deflector. Fumes and vapors are recycled through the top of the grille. To order, see the “Assistance or Service” section.

Example Vent System

90 elbow		Wall cap
	6 ft (1.8 m)

2ft

(0.6 m)

The following example falls within the maximum vent length of 35 ft (10.7 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)
System length		= 13 ft (3.9 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. Deflector	A. Roof cap
B. 6" (15.2 cm) round vent	B. 6" (15.2 cm) round vent

NOTE: If codes permits, wall venting can be an option for 2-story homes.

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).

■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.
