Installation Preparation

ADVANCE PLANNING

Ductwork Planning

• These vent hoods are equipped for 8” round

ductwork.

• Determine the exact location of the vent hood.

• Plan the route for venting exhaust to the outdoors.

• Use the shortest and straightest duct route

possible. For satisfactory performance, duct run

should not exceed 100 ft. equivalent length for any

duct configurations.

• Refer to “Duct Fittings” chart to compute the

maximum permissible length for duct runs to the

outdoors.

• Use rigid metal ductwork only.

• Install a roof cap with damper at the exterior

opening. Order the cap and any transitions and

length of duct needed in advance.

• When applicable, install any makeup (replacement)

air system in accordance with local building code

requirements. Visit GEAppliances.com for available

makeup air solutions.

Ceiling Framing for Adequate Support

• These vent hoods are heavy. Adequate structural

support must be provided. The ceiling structure

must be capable of supporting the weight of the

hood and any inadvertent user contact loads

(approximately 200 pounds). The hood support

frame will be supported by 2 x 4 cross framing.

• Installation will be easier if the vent hood is

installed before the cooktop or countertop below is

installed.

Duct Covers

• All models are shipped with duct covers. For

supplied duct cover ceiling heights for vented

installation and recirculating installation, refer to

table on page 12.

POWER SUPPLY

IMPORTANT - (Please read carefully)

WARNING:

FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE

PROPERLY GROUNDED.

Remove house fuse or open circuit breaker before

beginning installation.

Do not use an extension cord or adapter plug with

this appliance. Follow National Electrical Codes or

prevailing local codes and ordinances.

Electrical Supply

This vent hood must be supplied with 120V, 60Hz,

and connected to an individual, properly grounded

branch circuit, and protected by a 15 or 20 amp

circuit breaker or time delay fuse.

• Wiring must be 2 wire with ground.

• If the electrical supply does not meet the above

requirements, call a licensed electrician before

proceeding.

• Route house wiring in the ceiling, as close to the

installation location as possible. Allow additional

length from ceiling joists to reach the junction box

on the bottom of the hood support frame.

• Connect the wiring to the house wiring in

accordance with local codes.

Grounding Instructions

The grounding conductor must be connected to

a ground metal, permanent wiring system, or an

equipment-grounding terminal or lead on the

hood.

WARNING:

The improper connection of equipment-grounding

conductor can result in a risk of electric shock. Check

with a qualified electrician or service representative

if you are in doubt whether the appliance is properly

grounded.
