Gas Downdraft Cooktop
Advance
Planning
The combined installation of a downdraft vent
and cooktop require careful consideration.
Countertop Requirements:
The countertop must have a deep flat surface
to accommodate the cooktop and the vent.
Countertops with a rolled front edge and
backsplash may not provide the flat surface
area required.
Clearances
•The downdraft system with blower, motor
and ductwork will occupy the cabinet below
the cooktop. Drawers cannot be installed
below this cooktop.
•Refer to “Dimensions & Clearances” for
information on appropriate placement and
necessary clearances when planning installation.
•Avoid placing cabinetry directly above the
cooktop when possible.
•If cabinetry is used above cooking surface:
–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
Base Cabinet Requirements:
This installation requires a 24" min. deep
cabinet base. The cabinet must be at least 36"
wide.
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 have 18" minimum clearance between countertop and cabinet bottom.
•Installation must conform with local codes.
In the absence of local codes, the gas cooktop
must comply with the National Fuel Gas Code,
ANSI Z223.1, latest edition.
Ductwork Advance Planning
Prepare ductwork to vent to outdoors:
•Use the shortest and straightest duct run
possible:
–Duct run should not exceed equivalent
length of 150 feet.
–Refer to “Duct Fittings” chart to calculate
equivalent length for various duct
configurations.
Gas and Electrical Locations
Plan the placement of the electrical outlet and
gas carefully. Gas and electrical outlets cannot
be placed on the back wall of the cabinet
because it may interfere with the downdraft
plenum.
•The downdraft blower system is designed to
use 3-1/4"x10" 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.
•Refer to “Power Supply Locations” page 8 for
details.

Power Supply
Locations
Gas supply:
These cooktops are designed to operate on
natural gas at 4" of water column pressure or
on LP gas at 10" of water column pressure.
–These cooktops are shipped from the
factory set for natural gas. If you decide
to use this cooktop with LP gas, conversion
adjustments must be made by a service
technician or other qualified person.
JXLP56 conversion kit is required for
LP operation.
•The pressure regulator must be connected in
series with the manifold of the cooktop and
must remain in series with the supply line
regardless of type of gas being used.
For proper operation, the maximum inlet
pressure to the regulator must be no more
than 10" water column pressure for natural
gas and 14" water column pressure for LP gas.
•When checking the regulator, the inlet
pressure must be at least 1" greater than the
regulator output setting.
–If the regulator is set for 4" of water column
pressure, the inlet pressure must be at
least 5".
–If the regulator is set for 10" of water
column pressure, the inlet pressure must
be at least 11".
For ease of installation, and if local codes
permit, the gas supply line into the cooktop
should be 1/2" or 3/4" ID flexible metal
appliance connector, three to five feet long.
Note: Purchase new flexible line. DO NOT
USE OLD, PREVIOUSLY USED FLEXIBLE
LINE.
•Make gas connection through rear wall, or
on cabinet floor at rear, as illustrated.
Electrical supply:
•A properly-grounded 3-prong receptacle
should be located within reach of cooktop’s
four foot power cord.
– Locate the receptacle inside the cabinet on
the right side wall. See illustration.
IMPORTANT: (Please read carefully).
FOR PERSONAL SAFETY, THIS APPLIANCE
MUST BE PROPERLY GROUNDED.
The power cord of this appliance is equipped
with a three-prong (grounding) plug which
mates with a standard three-prong grounding
wall receptacle to minimize the possibility of
electric shock hazard from this appliance. The
customer should have the wall receptacle and
circuit checked by a qualified electrician to
make sure the receptacle is properly
grounded and has correct polarity.
Where a standard two-prong wall receptacle is
encountered, it is the personal responsibility
and obligation of the customer to have it
replaced with a properly grounded threeprong wall receptacle.
Do Not, Under Any Circumstances, Cut Or
Remove The Third (ground) Prong From The
Power Cord.
Do not use an extension cord.

•Ductwork MUST be vented to the outside –
never into a crawl space, attic or other
enclosed space.
•6" PVC duct should be used when installing
under a concrete slab.
Note: Local building code must be followed
for installation and in specifying approved
type and schedule of PVC duct used.
• DO NOT USE flexible plastic ducting.
• Always use appropriate roof or wall cap with
damper. Laundry type wall caps should
never be used.
• Use the straightest duct run possible.
• For satisfactory performance the duct run
should not exceed 150 ft. or its equivalent
•Install the supplied pressure regulator and
nipple in the gas line as close to the cooktop
inlet as possible. Allowances for ventilation
ducting may be necessary.
–Make sure the regulator is installed in the
right direction.
•Install a manual shut-off valve in the gas line
in an easily accessible location.
Note: Instead of using solid piping to connect
to pressure regulator, an approved flexible
metal appliance connector may be used
between the pipe stub and the shut-off valve
and the pressure regulator, if local codes
permit.
– Appropriate flare nuts and adapters are
required at each end of the flexible
connector.
•Turn on the gas. Check for leaks using a
liquid leak detector at all joints in the system
(the pressure test nipple is adjacent to the
gas inlet pipe on the rear right hand side of
the cooktop bottom.

to be sure all cutout edges are concealed
and there are no gaps.
•Carefully, lift and remove the cooktop.
•Cut a 3/16" gasket strip in half. Peel off the
backing and apply to the underside of the
glass cooktop edge.
–on each side at least 3/8" from the back
and as close to the edge as possible without

to the cabinet with angle brackets (not
supplied).
–Remove one screw at the bottom of the
cooktop body on both sides and secure the

• The base is designed to be mounted to studs
on 16" centers. Use the dimensions shown to
determine the location of the ducting and
wiring through the wall.
– Or Place the base against the exterior wall
and mark the 6 mounting locations, the 6"
duct location and the hole for the wiring.
Use pencil or chalk.
• The bottom of the base assembly must be
10" min. above the ground. There should be
no obstructions to the discharge from the
damper.
• Cut a 6-1/8" dia. hole in the vertical structure to accommodate a 6" round duct
another hole for the wiring.
• Drill 6 pilot holes through the wall for the
6/16" fasteners.

CAUTION:
do not damage electrical wiring or hidden utilities.
Check for interference with floor joists and stud walls. If
necessary, locate the base to provide a secure
installation.
• Place a 6" round duct through the hole
extending approximately 3" from the wall to
provide a proper seal with the blower.
Secure the duct to the building structure to
prevent it from being pushed back when the
blower is installed.
• Flatten the shipping box to use as a pad.
• Place the unit on its back onto the protective
pad.
• Remove the wire box on the plenum.
