not be allowed to accumulate on fan or filter.
D. Use proper pan size. Always use cookware
appropriate for the size of the surface element.
WARNING –
TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:
A. Installation work and electrical wiring must be
done by qualified person(s) in accordance with
all applicable codes and standards, including
fire-rated construction.
B. Sufficient air is needed for proper
combustion and exhausting of gases through
the flue (chimney) of fuel burning equipment
to prevent back drafting. Follow the heating
equipment manufacturer’s guidelines and
safety standards such as those published by
the National Fire Protection Association
(NFPA), the American Society for Heating,
Refrigeration and Air Conditioning Engineers
(ASHRAE) and the local code authorities.
C. When cutting or drilling into wall or ceiling,
do not damage electrical wiring and other
hidden utilities.
D. Ducted fans must always be vented
to the outdoors.

Using the downdraft system.
Raise/Lower Switch (30″ models only)
Turn the downdraft blower ON by pressing
the raise/lower switch located at the top
right of the vent. Place your finger on the
“center” of the switch and hold until you
observe the vent moving, then release.
The air vent will rise. Use the selector switch
to turn the blower ON, OFF or to change
the blower speed.
NOTE: For most convenient operation, set the
blower to the speed you use most often. The
blower will come on to this speed whenever
the unit is raised.
The vent may be lowered by again pressing
the raise/lower switch at the top right side
of the vent. The blower, if left on, will
automatically go off when the vent is
lowered.
On some models, the Raise/Lower
switch is located at the top right of
the vent.
Use the selector switch to turn the
blower ON, OFF or to change the
blower speed.
Remote Raise/Lower Switch (36″ models only)
The 36″ models have a remote raise/lower
switch. It operates in the same manner as
the switch located on the vent. This switch
may be located beside the cooktop or in a
convenient location.
Raise/Lower switch location
may vary.
Using the Cooktop
ꢀ To avoid injury, be sure fingers are clear
of the downdraft cover when it is being
lowered.
CAUTION:
Be careful when raising
or lowering the downdraft. Be sure pots, pot handles
and other objects are clear of the downdraft
and cannot be struck or tipped by the downdraft
being raised.
ꢀ Keep hands and fingers away from all
downdraft parts.
NOTE: There is a slight trim overhang at each end
of the vent.

Cooking Tips
The high air movement of this downdraft
system can increase the cooking times for
some foods. It may take longer to reach
high cooking temperatures if the downdraft
is turned to high right away. Adjust the fan
speed for best cooking results.
Canning
When canning foods in a water-bath canner,
a gentle but steady boil must be maintained
continuously for the required time.
When canning foods in a pressure canner,
the pressure must be maintained
continuously for the required time.
For best results when heating oil for deep
frying or when boiling water, use the front
surface units or wait until the water is
boiling or the oil is at frying temperatures
before turning on the downdraft.
Use of the blower at HIGH speed when
canning may reduce the temperature
enough to stop boiling. While canning,
we recommend using the downdraft at
LOW speed and using the front surface unit.
The downdraft may not completely capture all the
steam from pans on the front burners.
Care and cleaning of the downdraft system.
Grease Filters
The efficiency of your downdraft depends
on a clean filter. Frequency of cleaning
depends on the type of cooking you do.
Grease filters should be cleaned at least
once a month. Never operate the downdraft
without the filters in place.
be used to remove embedded soil. Rinse,
shake and remove moisture before
replacing.
Filters may also be cleaned in the
dishwasher.
With careful handling, the filter will last for
years. If replacement becomes necessary,
order the part from your dealer.
To remove: Pull the filters out by grasping
them and pulling straight up.
To clean: Soak and then agitate in a hot
detergent solution. Light brushing may
Painted or Metal Surfaces
Clean greasy surfaces frequently, using
a mild detergent.
Do not use abrasive cloth, steel wool pads or
scouring powder because they will mar the
surface.
Stainless Steel Surfaces (on some models)
To inquire about purchasing stainless steel
appliance cleaner or polish, or to find the
location of a dealer nearest you, please call
our toll-free number:
Do not use a steel wool pad; it will scratch
the surface.
To clean the stainless steel surface, use
warm sudsy water or a stainless steel cleaner
or polish. Always wipe the surface in the
direction of the grain. Follow the cleaner
instructions for cleaning the stainless steel
surface.

CLEARANCES
DUCTWORK
• Installation must conform with local codes.
Prepare ductwork to vent to the outdoors.
• The downdraft system with blower, motor
and duct work will occupy the cabinet
below the countertop and cooktop.
• Use the shortest and straightest duct run
possible.
The maximum permissible length for duct
run is 150 feet.
• The blower/motor assembly can be located
below the cabinet floor. The assembly will
fit between 16″ floor joists.
Refer to Duct Fittings chart to calculate
equivalent length for various duct
configurations.
In this installation a transition to 6 ″ round
is required.
• The downdraft blower system is designed
to use 31⁄4″ 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.
• The blower motor assembly can also be
installed outdoors. Order JXBC67 for
remote blower installations outdoors.
• Refer to Dimensions and Clearances for
information on appropriate placement
and necessary clearances when planning
installation.
• Determine the need for a wall cap or roof
cap. Purchase the cap in advance from
your home building center or plumbing
supply.
• Refer to your specific cooktop installation
instruction for other appropriate clearances.
• Avoid placing cabinetry directly above the
cooking surface when possible.
• If cabinetry is used above the cooking

surface:
Installation must conform with local codes.
Plan the placement of the electrical outlet
and gas (if used) carefully. Gas or electrical
outlets cannot be placed on the back wall of
the cabinet because it may interfere with the
downdraft plenum.
Use cabinets no more than 13″ deep.
Maintain 30″ minimum clearance between
cooktop and unprotected cabinets directly
above cooktop.
If clearance is less than 30″, protect cabinet
bottoms with flame-retardant millboard at
least 1/4″ thick or gypsum board at least
3/16″ thick covered with 28 gauge sheet
steel or .02″ thick copper.
Clearance between cooktop and protected
cabinetry must not be less than 24″.
Install a standard electrical outlet within
reach of the vents’ 2 foot long power cord.
• The vent and a gas cooktop combination
can operate from the same 120V standard
duplex outlet.
• Electric cooktops must operate from
a separate 240V junction box.
EXCEPTION: Installation of a listed
microwave oven or cooking appliance over
the cooktop shall conform to the installation
instructions packed with that appliance.
REMOTE SWITCH
• Working areas adjacent to the cooktop
should maintain 18″ minimum clearance
between countertop and cabinet bottom.
(for 36″ models only)
The downdraft vent has a separate
raise/lower switch. Plan to install the switch
in a convenient location outside of the
vent/cooktop cutout.
