Installation Preparation - GE PV977 Owner’s Manual And Installation Instruction

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.

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

• 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.
