INSTALLATION PREPARATION
ADVANCE PLANNING
Duct Install Planning
■ This hood is designed to be vented vertically
through the ceiling. Use a 8" round duct. Use
locally supplied elbows to vent horizontally
through the rear wall. An 8" duct is required for
optimal performance but a minimum of 6" duct
can be used to ensure consistent performance.
■ 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.
NOTE:
Flexible vent is not recommended. Flexible
vent creates back pressure and air turbulence that
greatly reduces performance.
■ Maximum equivalent duct length for 100 CFM:
150 foot for vent hoods.
■ Install a wall cap or roof cap with damper at the
exterior opening. Purchase 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.
Vent system can terminate either through the roof
or the wall. To vent through a wall, a 90° elbow is
needed and installed immediately above the hood.
Wall and Ceiling Framing for Adequate Support
This vent hood is heavy and the cabinet
structure needs to support the weight of the
loaded insert sleeve. Adequate structural support
must be provided in all types of installations.
■
Installation will be easier if the vent hood is
installed before the cooktop is installed.

RECIRCULATION INSTALL PLANNING
This hood may be installed in recirculation mode.
The charcoal filter (not included) is necessary for
recirculation installation.
ADVANCE PLANNING (CONT.)
Custom Cabinet Frame Planning
■
The custom canopy or cabinet should have a
rectangular hole to accommodate the custom
hood insert by itself. This hole is the same
size for both a wall installation and an island
installation. Ensure parallelism and levelness of
the cabinet so that it doesn't affect flushness of
the hood with the cabinet.
