For your safety, the information in this manual must be followed to minimize the risk of fire or
explosion, electric shock, or to prevent property damage, personal injury, or loss of life.
The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to
publish a list of substances known to the state to cause cancer, birth defects or other reproductive
harm, and requires businesses to warn customers of potential exposure to such substances.
Operating Instructions
Safety Instructions
Gas appliances can cause minor exposure to four of these substances, namely benzene, carbon
monoxide, formaldehyde and soot, caused primarily by the incomplete combustion of natural gas or
LP fuels. Properly adjusted burners, indicated by a bluish rather than a yellow flame, will minimize
incomplete combustion. Exposure to these substances can be minimized by venting with an open
window or using a ventilation fan or hood.
Care and Cleaning
Have the installer show you the location of the cooktop gas shut-off valve and how to shut it
off if necessary.
■ Have your cooktop installed and properly
grounded by a qualified installer, in
accordance with the Installation
Instructions. Any adjustment and service
should be performed only by qualified gas

Troubleshooting Tips
■ Do not store flammable materials near
a cooktop.
■ Flaming grease outside a pan can be put
out by covering it with baking soda or, if
available, by using a multi-purpose dry
chemical or foam-type fire extinguisher.
Care and Cleaning
■ Never wear loose fitting or hanging
garments while using the appliance.
Be careful when reaching for items stored
in cabinets over the cooktop. Flammable
material could be ignited if brought in
contact with flame or hot surfaces and
may cause severe burns.
■ Do not use water on grease fires. Never pick
up a flaming pan. Turn the controls off.
Smother a flaming pan on a surface burner
by covering the pan completely with a wellfitting lid, cookie sheet or flat tray. Use a
multi-purpose dry chemical or foam-type
fire extinguisher.
Operating Instructions
■ Always keep wooden and plastic utensils
and canned food a safe distance away from
your cooktop.
■ Never use the cooktop as a cutting board.
Safety Instructions
■ CAUTION: Items of interest to
Use proper pan size—avoid pans that are unstable or easily tipped. Select cookware having flat
bottoms large enough to cover burner grates. To avoid spillovers, make sure cookware is large
enough to contain the food properly. This will both save cleaning time and prevent hazardous
accumulations of food, since heavy spattering or spillovers left on cooktop can ignite. Use pans with
handles that can be easily grasped and remain cool.

Troubleshooting Tips
Care and Cleaning
■ Always use the LITE position when igniting
the top burners and make sure the burners
have ignited.
■ Never leave the surface burners
unattended at high flame settings.
Boilovers cause smoking and greasy
spillovers that may catch on fire.
■ Use only dry pot holders—moist or damp
pot holders on hot surfaces may result in
burns from steam. Do not let pot holders
come near open flames when lifting
cookware. Do not use a towel or other bulky
cloth in place of a pot holder. Such cloths
can catch fire on a hot burner.
■ When using glass cookware, make sure it
is designed for cooktop cooking.
■ To minimize the possibility of burns,
ignition of flammable materials and
spillage, turn cookware handles toward the
side or center of the cooktop without
extending over adjacent burners.
■ Always turn the surface burner controls off
before removing cookware.
■ Carefully watch foods being fried at a high
flame setting.
■ Always heat fat slowly, and watch as it heats.
■ Do not leave any items on the cooktop. The
hot air from the vent may ignite flammable
items and will increase pressure in closed
containers, which may cause them to burst.
■ If a combination of oils or fats will be used
in frying, stir together before heating or as
fats melt slowly.
■ Do not use a wok on the cooking surface if
the wok has a round metal ring that is
placed over the burner grate to support the
wok. This ring acts as a heat trap, which may
damage the burner grate and burner head.
Also, it may cause the burner to work
improperly. This may cause a carbon
monoxide level above that allowed by
current standards, resulting in a health
■ Foods for frying should be as dry as
possible. Frost on frozen foods or moisture
on fresh foods can cause hot fat to bubble
up and over the sides of the pan.
■ Use the least possible amount of fat for
effective shallow or deep-fat frying. Filling
the pan too full of fat can cause spillovers
when food is added.
■ Use a deep fat thermometer whenever
possible to prevent overheating fat beyond
the smoking point.
■ Never try to move a pan of hot fat,
especially a deep fat fryer. Wait until the fat
is cool.
■ When flaming foods are under the hood,
turn the fan off. The fan, if operating, may
spread the flames.
Adjust the burner flame size so it does not extend beyond the edge of the cookware. Excessive flame
is hazardous.
■ Never leave jars or cans of fat drippings
on or near your cooktop
■ Don’t use aluminum foil to line burner
bowls. Misuse could result in a fire hazard
or damage to the cooktop.
■ Do not cover or block the area around the
cooktop knobs. This area must be kept
clear for proper ventilation and burner
■ Clean only parts listed in this Owner’s
Operating Instructions
Care and Cleaning
■ Do not leave plastic items on the cooktop—
they may melt if left too close to the vent.
■ Keep all plastics away from the surface
■ If you smell gas, turn off the gas to the
cooktop and call a qualified service
technician. Never use an open flame to
locate a leak.
■ To avoid the possibility of a burn, always be
certain that the controls for all burners are
at the off position and all grates are cool
before attempting to remove them.
■ Never clean the cooktop surface when it is
hot. Some cleaners produce noxious fumes
and wet cloths could cause steam burns if
used on a hot surface.

How to Light a Burner
Your cooktop burners are lit by electric
ignition, eliminating the need for
standing pilot lights with constantly
burning flames.
Push the control knob in and turn it
counterclockwise to the desired position
from HIGH to LO. After the burner ignites,
turn the knob in either direction to adjust
the flame size. To turn a burner off, turn
the knob clockwise as far as it will go, to
the OFF position.
■ Do not operate a burner for an extended period
of time without cookware on the grate. The
finish on the grate may chip without cookware
to absorb the heat.
■ Check to be sure the burner you turn on is the
one you want to use.
■ Be sure the burners and grates are cool before
you place your hand, a pot holder, cleaning
cloths or other materials on them.
The right rear burner is best for smaller
pans and cooking operations requiring
carefully controlled simmering
The front right burner is the high power
burner for larger pans and fast boiling
For safe handling of cookware, never let the
flames extend up the sides of the cookware.
Watch the flame, not the knob, as you
reduce heat. The flame size on a gas
burner should match the cookware
you are using.
Any flame larger than the bottom of the
cookware is wasted and only serves to heat
the handle.

Wok This Way
Use a flat-bottomed wok.
We recommend that you use a flat-bottomed
wok, available at your local retail stores, or use
the Wok Holder accessory with traditional round
bottomed woks. The Wok Holder accessory,
model JXWK, can be ordered from your
appliance dealer.
The Wok Holder fits on top of the
cooktop grate to provide support and
proper air circulation for traditional
round bottom woks only. Do not use flat
bottomed woks with the Wok Holder.
Operating Instructions
Safety Instructions
Using your cooktop
Do not use a wok on any other support
ring. Placing the ring over the burner
grate may cause the burner to work
improperly, resulting in carbon
monoxide levels above allowable current
standards. This could be dangerous to
your health. Do not try to use such woks
without the ring unless you are using the
Wok Holder. You could be seriously
burned if the wok tipped over.
Care and Cleaning
Aluminum: Medium-weight cookware is
recommended because it heats quickly
and evenly. Most foods brown evenly in
an aluminum skillet. Use saucepans with
tight fitting lids when cooking with
minimum amounts of water.
Heatproof Glass Ceramic: Can be used
for either surface or oven cooking.
It conducts heat very slowly and cools
very slowly. Check cookware
manufacturer’s directions to be sure it
can be used on a gas cooktop.
Enamelware: Under some conditions,
the enamel of some cookware may
melt. Follow cookware manufacturer’s
recommendations for cooking methods.
Stainless Steel: This metal alone has
poor heating properties and is usually
combined with copper, aluminum
or other metals for improved heat
distribution. Combination metal skillets
usually work satisfactorily if they are used
with medium heat as the manufacturer
Troubleshooting Tips
Glass: There are two types of glass
cookware: those for oven use only
and those for cooktop cooking
(saucepans, coffee and tea pots).
Glass conducts heat very slowly.
Cast Iron: If heated slowly, most
skillets will give satisfactory results.
Stove Top Grills
Customer Service
Do not use stove top grills on your
sealed gas burners. If you use the stove
top grill on the sealed gas burner it will
cause incomplete combustion and can
result in exposure to carbon monoxide
levels above allowable current
standards. This can be hazardous to
your health.
Safety Instructions
Cooktop vent system.
The built-in vent system helps remove
cooking vapors, odors and smoke from
foods prepared on the cooktop.
Continuous use of the vent system
helps keep the kitchen comfortable
and less humid, reducing cooking
odors and soiling moisture that
normally creates a frequent need
for cleaning.
Operating Instructions

Duct Fittings
Use the chart at the right to compute maximum
permissible lengths for duct runs to outdoors.
NOTE: Do not exceed maximum permissible
equivalent lengths!
Flexible ducting:
If flexible metal ducting is used, all the equivalent
feet values in the table should be doubled. The
flexible metal duct should be straight and smooth
and extended as much as possible.
Do NOT use flexible plastic ducting.
NOTE: Any home ventilation system, such as a
cooktop with a downdraft exhaust mechanism, may
interrupt the proper flow of combustion air and
exhaust required by fireplaces, gas furnaces, gas
water heaters and other naturally vented systems.
To minimize the chance of interruption of such
naturally vented systems, follow the heating
equipment manufacturer’s guidelines and safety
standards such as those published by NFPA and

Power Supply Locations
Electrical Supply:
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. Order
JXLP56 Conversion Kit.
■ 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
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 a new flexible line. DO NOT USE AN

The built-in gas downdraft cooktop features pilotless
electric ignition for energy savings and reliability. It
operates on a 120 volt, 60 Hz power supply. A
separate circuit, protected by a 15 amp time delay
fuse or circuit breaker, is required.
■ A properly grounded 3-prong receptacle should be
located within reach of cooktop’s four foot power
IMPORTANT: (Please read carefully.)
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 three-prong wall receptacle.
Do Not, Under Any Circumstances, Cut Or Remove The
Third (ground) Prong From The Power Cord.
Do not use an extension cord.
Step 1
Step 2
Install Downdraft Vent
Install the Ductwork
Place the downdraft vent into the countertop cutout,
against the back side.
Use minimum 26 gauge galvanized or 24 gauge
aluminum duct in 6″ round or 31⁄4″ x 10″ size, or a
combination of both. PVC duct should be used if
installing under a poured concrete slab. DO NOT use
flexible plastic ducting.
■ Always use an appropriate roof or wall cap with
damper. Laundry type wall caps should never be
■ Use the straightest duct run possible.
■ For satisfactory performance the duct run should
not exceed 150 ft. or its equivalent length if bends or
other various fittings are used. Refer to table of
equivalent lengths for various duct configurations.

in the gas line as close to the cooktop inlet as
possible. Allowances for ventilation ducting may be
Make sure the regulator is installed in the right
■ 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.)
IMPORTANT: Disconnect the cooktop and the
individual shut-off valve from the gas supply piping
system during any pressure testing of that system at
test pressures greater than 1/2 psig. Isolate the
cooktop from the gas supply piping system by closing
the individual manual shut-off valve to the cooktop
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig.
■ To insure a good fit, position the cooktop over the
