Desi n Information
Clearances
, The downdraft system with blower, motor and
ductwork will occupy the cabinet below the
countertop and cooktop.
• The blower/motor assembly can be located
below the cabinet floor. The assembly will fit
between 16" floor joists. Order JXRB67 for indoor
remote locations.
Refer to your specific cooktop installation
instruction for appropriate clearances.
, Installation must conform with local codes.
Ductwork
Prepare ductwork to vent to the outdoors.
, Use the shortest and straightest duct run possible.
, The maximum permissible equivalent length for
duct run is 100 feet.
• Refer to "Duct Fittings" chart to calculate
equivalent length for various duct configurations.
o The downdraft blower system is designed to use
3-1/4" x 10" ductwork. It can be transitioned to 6"
round.
, Ductwork MUST be vented to the outside-never
into a crawl space, attic or other enclosed space.
, Determine the need for a wall cap or roof cap.
Order the cap 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.
Electricaland Gas Locations
Plan the placement of the electrical outlet and gas
connections (if used) carefully. Electrical outlets and
gas connections cannot be placed on the back wall
of the cabinet because it may interfere with the
downdraft plenum. Refer to POWER SUPPLYsection
for information on location of electrical and gas
connections.
, Install a standard electrical outlet on the right side
of the cabinet within reach of the vent's two-foot-
long power cord.
o The vent and a GE or Monogram gas cooktop
combination can operate from the same 120-volt
standard duplex outlet.
, Electric cooktops must operate from a separate
240-volt junction box.
• A 90 ° elbow (not supplied) can be installed onto
the inlet of the gas cooktop and route the gas
connections to avoid interference when installed
with a downdraft vent or other cabinetry features.
, The hood must vent down or to the left when
installed with a GE or Monogram gas cooktop to
avoid interference with the inlet of the gas cook-
top.
