Installation Preparation

ADVANCE PLANNING
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.
When applicable, install any makeup (replacement)
air system in accordance with local building code
requirements. Visit GEAppliances.com for available
makeup air solutions.
CAUTION: To reduce risk of fire and to
properly exhaust air, be sure to duct air outside –
do not vent exhaust air into spaces within walls or
ceilings or into attics, crawl spaces, or garages.
PRUDENCE : Il faut prendre soin
d’installer un conduit vers l’extérieur pour
réduire le risque d’incendie et pouvoir évacuer
l’air correctement. Il ne faut pas évacuer l’air
correctement. Il ne faut pas évacuer l’air dans
l’espace entre les parois d’un mur, un plafond ou un
grenier, un espace sanitaire ou un garage.
Use metal ductwork only. These hoods must use
6” round duct. It can transition to 3-1/4” x 12”,
reducing the maximum equivalent duct length to
75 feet.
Install a wall cap with damper or roof cap at the
exterior opening. Order the wall or roof cap and
any transition needed in advance.
Wall Framing for Adequate Support
This vent hood is heavy. Adequate structural
support must be provided in all types of
installations. The
hood must be secured to vertical studs in the
wall, or to a horizontal support. For wall mounting
installations, see pages 9 and 14. For under-
cabinet installations, see page 20.
The vent hood and wall cabinet, if used, should be
on site before final framing and wall finishing. This
will also help to accurately locate the duct work
and electrical service.
POWER SUPPLY

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
These vent hoods 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 through conduit as close to the
installation location as possible, in the ceiling or
back wall.
Use a conduit connector to secure the conduit to
the junction box.
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
the 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.
