KitchenAid Ventilation Hood Electrical Requirements, Venting methods, Example vent system

For Best Performance:

■Do not install 2 elbows together.

■Use no more than three 90° elbows.

■If an elbow is used, install it as far away as possible from the hood’s vent motor exhaust opening.

■Make sure there is a minimum of 24" (61 cm) of straight vent between the elbows if more than one elbow is used.

■The length of vent system and number of elbows should be kept to a minimum to provide efficient performance.

Cold Weather Installations

An additional backdraft damper should be installed to minimize backward cold air flow and a nonmetallic thermal break installed to minimize conduction of outside temperatures as part of the vent system. The damper should be on the cold air side of the thermal break.

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 vented installations. Vent system can terminate through either the roof or wall. A

6" (15.2 cm) round vent system must be used. The vent system length should not exceed 35 ft (10.7 m).

The exhaust collar can also be directed to vent out the rear of the hood, as shown in option 3.

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)

Example vent system

	90° elbow		6 ft. (1.8 m)		wall cap
2	ft.
	(0.6 m)
Maximum length				= 35 ft (10.7 m)
1-90° elbow				= 5 ft (1.5 m)
8 ft (2.4 m) straight				= 8 ft (2.4 m)
1 - wall cap				= 0 ft (0 m)
System length				= 13 ft (3.9 m)

NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that greatly reduce performance.

Electrical Requirements

IMPORTANT: Observe all governing codes and ordinances. Save Installation Instructions for electrical inspector’s use.

It is the customer’s responsibility to contact a qualified electrical installer, and to assure 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.
