Installation Preparation
ADVANCE PLANNING
Duct Install Planning
• This hood may be vented vertically through upper
cabinets, soffit or ceiling. A duct transition piece is
supplied for vertical exhaust. Use locally supplied
elbows to vent horizontally through the rear wall.
• Use metal ductwork only.
• Determine the exact location of the vent hood.
• 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 wall cap or roof cap with damper at the
exterior opening. Order the wall or roof cap and
any transition 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.
Wall Framing for Adequate Support
• This vent hood is heavy. Adequate structural
support must be provided. The hood must be
secured to vertical studs in the wall. See page 14.
• We strongly recommend that the vent hood with
duct cover be on site before final framing and wall
finishing. This will also help to accurately locate
the ductwork and electrical service.
OPTIONAL ACCESSORIES
Duct Cover
A decorative duct cover is available to
accommodate 8 to 10 ft. ceiling heights. The duct
cover will expand from 12” minimum or 24” to 36”
maximum height.
• The duct cover conceals the ductwork running
from the top of the hood to the ceiling.
• The duct cover accessory fits both 30” and 36”
wide models. Order the duct cover accessory at
the same time as the vent hood. All accessories
should be on site at the time of hood installation.
