Advance Planning
DUCTWORK PLANNING
• This hood is designed to be vented vertically
through the ceiling. Use locally supplied elbows
to vent horizontally through the rear wall.
• 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 10
Ļ
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.
• This vent hood must use a 6” round duct. The
6” round duct can transition to 3-1/4” x 10”
or 3-1/4” x 12”.
• Install the house duct to run horizontally between
ceiling joists or straight up through the roof.
• Install a wall or roof cap with damper at the
exterior opening. Order the wall or roof cap
and any transition 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.
WARNING:
TO REDUCE THE RISK OF
FIRE, USE ONLY RIGID METAL DUCTWORK.
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 9
or 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.
• Installation will be easier if the vent hood is
installed before the cooktop and countertop are
installed.
ADVANCE PLANNING
A duct cover accessory may be required for your
hood installation depending on ceiling height.
