PREPARE TO INSTALL THE HOOD
ADVANCE PLANNING
Duct Install Planning
Determine the exact location of the vent hood.
Use rigid metal ductwork only.
Plan the route for venting exhaust to the
outdoors. To maximize the ventilation
performance of the vent system:
1. Minimize the duct run length and number of
transitions and elbows.
2. Maintain a constant duct size.
3. Seal all joints with duct tape to prevent any
leaks.
4. Do not use any type of flexible ducting.
Use the shortest and straightest duct route
possible.
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.
This Hood MUST Use an 8" Round Duct. It Can Transition to a 3-1/4" x 12" Duct.
DO NOT use flexible plastic ducting.
NOTE: Any home ventilation system, such as a ventilation hood, may interrupt the proper flow of combustion
air and exhaust required by fireplaces, gas furnaces, gas water heaters and other naturally vented systems.
To minimize the chance of interruption of such naturally vented systems, follow the heating equipment
manufacturer's guidelines and safety standards such as those published by NFPA and ASHRAE. When
applicable, install any makeup (replacement) air system in accordance with local building code requirements.

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.
