INSTALLATION SAFETY
INSTRUCTIONS

TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:

Installation work and electric wiring

must be done by qualified person(s)
in accordance with all applicable codes
and standards, including fire-rated
construction.

and other hidden utilities.

WARNING — To reduce the risk of

fire, use only metal ductwork.

IMPORTANT: These vents are

recommended for island installations.
Against-the-wall installations are
limited due to countertop depth
requirements. The vent and cooktop
combined depth requires an extra
deep flat countertop surface.

The countertop must be at least 26″ deep
with a flat surface area of 23

1

⁄2″ or more, front
to back. (NOTE: JGP932S, JP350SC, JP930SC
and JP938SC require 23

5

⁄8″ flat surface area.)
In addition, other clearances to the front
edge of the countertop must be considered.

• See specific cutout illustrations with your

cooktop model to determine requirements.

• A countertop with

a raised lip or rolled
front edge may not
allow enough flat
area for installation.

ADVANCE PLANNING

DUCTWORK

Prepare ductwork to vent to the outdoors.

• Use the shortest and straightest duct run

possible.
The maximum permissible length for duct

run is 150 feet.
Refer to Duct Fittings chart to calculate

equivalent length for various duct
configurations.

• 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. Purchase the cap in advance from
your home building center or plumbing
supply.

CLEARANCES

• Installation must conform with local codes.

• The downdraft system with blower, motor

and duct work 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.

In this installation a transition to 6 ″ round
is required.

• 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.

• 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.
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″.

EXCEPTION: Installation of a listed
microwave oven or cooking appliance over
the cooktop shall conform to the installation
instructions packed with that appliance.

• Working areas adjacent to the cooktop
should maintain 18″ minimum clearance
between countertop and cabinet bottom.

COOKTOP ELECTRICAL AND
GAS LOCATION

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.

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.

REMOTE SWITCH

(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.

INSTALLATION POSSIBILITIES

When the kitchen design calls for an against
the wall installation, move 24″ deep base
cabinet forward, 3″ to 5″. Filler panels can
be angled or flat to fill the space between
adjacent cabinets.

Maintain cutout clearances to front edge as specified.

In an island or peninsula, the countertop can
be extra deep to provide seating opposite of
the cooktop. Adding base cabinets on each
side of the cooktop provides extra storage
and countertop work space.
