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' 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.

TO REDUCE THE RISK OF FIRE,
