Venting Requirements

(Ducted installations only)

• Duct system must terminate to the outdoors, except for ductless (recirculating) installations.
• Do not terminate the duct system in an attic or other enclosed area.
• Do not use 4" (10.2 cm) laundry-type wall cap.
• Use metal duct only. A rigid metal duct is recommended. Plastic or metal foil duct is not recommended.
• The length of duct system and number of elbows should be kept to a minimum to provide efficient performance.

For the most efficient and quiet operation:

• Use rigid metal duct.
• Use no more than three 90^ elbows.
• Make sure there is a minimum of 24" (61.0 cm) of straight duct between the elbows if more than 1 elbow is used.
• Do not install 2 elbows together.
• Use clamps to seal all joints in the duct system.
• The duct system must have a damper. If the roof or wall cap has a damper, do not use the damper supplied with the range hood.
• Use caulking to seal exterior wall or roof opening around the cap.
• The size of the duct should be uniform.

Cold Weather Installations:

An additional backdraft damper should be installed to minimize backward cold air flow and a thermal break should be installed to minimize conduction of outside temperatures as part of the duct 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 duct 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.

Venting Methods

• This range hood is factory set for venting through the roof or through the wall. The exhaust opening is 6" (15.2 cm) round. A 6" (15.2 cm) round duct system is recommended. The duct system needed for installation is not included.
• If it is not possible to vent cooking fumes and vapors to the outside, the range hood can be used in the ductless (recirculating) version, using a charcoal filter kit. To order, see "Optional Parts" in the "Tools and Parts" section.

NOTE:

- If exhaust ducting is less than 5.91" (15.0 cm) in diameter or if flat ducting is used, the noise level of the range hood may increase and the exhaustion may be less efficient.

Calculating Duct System Length

The recommended duct system is 6" (15.2 cm) round duct with a maximum length of 35 ft (10.7 m). For the best performance, use no more than three 90° elbows.

To calculate the length of the system you need, add the equivalent feet (meters) for each duct piece used in the system.

Duct Piece	6" (15.2 cm) Round
45° elbow	2.5 ft (0.8 m)
90° elbow 5.0 ft (1.5 m)

Maximum equivalent duct length is 35 ft (10.7 m).

Example Duct System - 6" (15.2 cm)

90° elbow Wall cap 6 ft (1.8 m) 3 ft (0.93 m)

Maximum length = 35 ft (10.7 m)

1 - 90° elbow	= 5.0 ft (1.5 m)
1 – wall cap	= 0.0 ft (0.0 m)
6 ft (1.8 m) straight	= 6.0 ft (1.8 m)
3 ft (0.9 m) straight	= 3.0 ft (0.9 m)
System length	= 14.0 ft (4.3 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.
