5IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
instructions could result in serious injury or property damage. The qualified agency performing this
work assumes responsibility for the conversion.
• Remove all tape and packing materials before using the cooktop. Dispose of all plastic bags after
unpacking the cooktop. Never allow children to play with packing materials.
• Improper installation, adjustment, alteration, service or maintenance can cause injury or property
damage. For assistance or additional information, consult a qualified installer, service agency,
manufacturer (dealer) or your gas supplier.
• Never reuse old flexible connectors. The use of old flexible connectors can cause gas leaks and personal
injury. Always use NEW flexible connectors when installing a gas appliance.
• This appliance must not be installed with a ventilation system that blows air downward toward the
cooktop. This type of ventilation system may cause ignition and combustion problems with the gas
cooking appliance resulting in personal injury or unintended operation.
• Ask the installer to show you the location of the cooktop gas shut-off valve and how to shut it off if
necessary.
• Before servicing, disconnect the electrical supply.
Operation
• Gas appliances can cause minor exposure to four potentially hazardous substances, namely benzene,
carbon monoxide, formaldehyde and soot, caused primarily by the improper combustion of natural or
LP gas.
• Correctly adjusted burners, indicated by a blue rather than a yellow flame, will minimize improper
combustion. Exposure to these substances can be minimized by opening windows or using a ventilation
fan or hood.
• Do not place or use combustible materials, gasoline or other flammable vapors and liquids in the vicinity
of this or any other appliance.
• Stepping, leaning or sitting on this cooktop can result in serious injuries and cause damage to the
cooktop.
• Do not leave children alone or unattended where a cooktop is hot or in operation. They could be
seriously burned.
• Do not allow children to climb or play around the cooktop.
• Let the burner grates and other surfaces cool before touching them or leaving them where children can
reach them.
• Items of interest to children should not be stored in cabinets above a cooktop — children climbing on
the cooktop to reach items could be seriously injured.
• Do not let anyone climb or stand on the cooktop. They could damage the cooktop or tip it over, causing
severe personal injury.
• NEVER use the cooktop as a space heater to heat or warm the room. Doing so may result in carbon
monoxide poisoning and overheating of the cooktop.
• Never wear loose fitting or hanging garments while using the appliance. Be careful when reaching for
items placed in cabinets over the cooktop. Flammable material could be ignited if brought into contact
with flame or hot surfaces and may cause severe burns.
• Do not place flammable materials on or near the cooktop.
• Do not use water on grease fires. NEVER touch a flaming pan. Turn the controls off. Smother a flaming
pan on a surface burner by covering the pan completely with a well-fitting lid, cookie sheet or flat tray.
Use a multi-purpose dry chemical or foam-type fire extinguisher. 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.
• If the top burner flame goes out, gas is still flowing to the burner until the knob is turned to the OFF
position. Do not leave the burners ON unattended.

6IMPORTANT SAFETY INSTRUCTIONS
•Use proper pan size. Do not use pans that are unstable or easily tipped. Select cookware having flat
bottoms large enough to cover burner grates. To avoid spills, make sure cookware is large enough to
contain the food properly. This will save cleaning time and prevent hazardous accumulations of food.
Because heavy spattering or spills left on a range can ignite, use pans with handles that can be easily
grasped and remain cool.
• Never leave the surface burners unattended at high flame settings. Boilovers can cause smoking and
greasy spillovers may catch on fire.
• Control the top burner flame size so it does not extend beyond the edge of the cookware. Excessive
flame is hazardous.
• 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 instead of a pot holder.
• To prevent burns, ignition of flammable materials and spillage, turn cookware handles toward the side
or back of the cooktop without extending over adjacent burners.
• NEVER place 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.
• Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other
appliance.
• Storage on Appliance - Flammable materials should not be stored on the cooktop or near surface units.
This includes paper, plastic and cloth items, such as cookbooks, plasticware and towels, as well as
flammable liquids.
• Carefully watch foods being fried at a high flame setting.
• Always heat fat slowly, and watch as it heats.
• Use a deep fat thermometer if possible to prevent overheating fat beyond the smoking point.
• 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.
• LG does not recommend using a gas cooktop for the preparation of flaming foods. If you choose to
prepare flaming foods under a hood, turn the fan on.
• To prevent burns, always be sure that the controls for all burners are at the OFF position and all grates
are cool before attempting to remove them.
• 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.
• Do not place cooking oils or other flammable materials on or near the cooktop.
• Always turn knob to the OFF position before removing cookware.
• Do not store explosives, such as aerosol cans, on or near the cooktop. Flammable materials may explode
and result in fire or property damage.
• Do not obstruct the flow of combustion and ventilation air.
• Do not block the airflow into or out of the cooktop. It is necessary for proper combustion and ventilation.
• Always turn knobs to the LITE position when igniting the top burners and make sure the burners have
ignited.
• If frying a combination of oils or fats, stir together before heating or as fats slowly melt.
• Liquids such as water, coffee or tea are able to be overheated beyond the boiling point without
appearing to be boiling, due to surface tension of the liquid. Visible bubbling or boiling is not always
present when the container is removed from the cooktop. This could result in very hot liquids suddenly
boiling over when the container is disturbed or a spoon or other utensil is inserted into the liquid.
To reduce the risk of injury to persons
- Do not overheat the liquid.
- Stir the liquid both before and halfway through heating it.
- Do not use straight-sided containers with narrow necks.

7IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
SAVE THESE INSTRUCTIONS
- After heating, allow the container to stand on the cooktop for a short time before moving the
container.
- Use extreme care when inserting a spoon or other utensil into the container after heating.
Maintenance
• Do not attempt to repair or replace any part of the cooktop unless it is specifically mentioned in this
manual. All other service should be referred to a qualified technician.
• Clean the cooktop with caution. If a wet sponge or cloth is used to wipe spills on a hot cooktop, be careful
to avoid steam burns.
• Leak testing of the appliance shall be conducted according to the manufacturer’s instructions.
• Do not lift the cooktop. Lifting the cooktop can cause damage and improper operation of the cooktop.
• If the cooktop is located near a window, do not hang long curtains that could blow over the surface
burners and catch on fire.
CAUTION STATEMENTS
CAUTION
• To reduce the risk of minor or moderate injury to persons, malfunction, or damage to the product or
property when using this product, follow basic precautions, including the following:
Operation
• To prevent poor air circulation, place the cooktop out of the kitchen traffic path and away from drafty
locations.
• If using glass cookware, make sure it is designed for top-of-range cooking.
• If frying mixtures of oils or fats, stir to combine before heating.
• Do not use a wok on the surface burners 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 hazard.
• Foods for frying should be as dry as possible. Frost or moisture on foods can cause hot fat to bubble up
and over the sides of the pan.
• Never try to move a pan of hot fat, especially a deep fat fryer. Wait until the fat is cool.
• Do not place plastic items on the cooktop—they may melt if left too close to the vent.
• Keep all plastics away from the surface burners.
• To avoid burns, do not clean the cooktop surface until it has cooled.

OPERATION
Using the Surface Burners
Before Using the Surface Burners
Throughout this manual, features and appearance
may vary from your model.
• Make sure all grates on the cooktop are properly
placed before using any burner.
• Be sure the burners and grates are cool before
you place your hand, a pot holder, cleaning
cloths or other materials on them.
• Make sure all burners are in place.
• Do not operate the 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.
Lighting a Gas Surface Burner
• Be sure all the surface burners are placed in
their respective positions.
• Push the control knob in and turn it to the LITE
position.
• The clicking noise you hear is the sound of the
electric spark igniting the burner.
• A clicking sound may also be heard during
operation due to the flame detection function.
• To control the flame size, turn the knob. lf the
knob stays at LITE, it will continue to click.
• When one burner knob is turned to LITE, only
that burner sparks. Do not attempt to
disassemble or clean around any burner while
another burner is on. An electric shock may
result, which could cause you to knock over hot
cookware.
In Case of Power Failure
• In case of a power failure, you can light the gas
surface burners on the cooktop with a match.
Hold a lit match to the burner, then push in and
turn the control knob to the LITE position. Use
extreme caution when lighting burners this way.
• Surface burners in use when an electrical power
failure occurs will continue to operate normally.
Sealed Gas Burners
• The cooktop has five sealed gas burners. They
offer convenience, cleanability and flexibility to
be used in a wide range of cooking applications.
aMedium
bExtra Large (Dual)
cSmall
dLarge (Dual)
•Thesmallcburner offers a very low simmer
setting and is best for delicate foods such as
sauces that require long simmer times over low
heat.
• The medium aand large dburners are the
primary burners for most cooking. The
temperature range on these burners can handle
a wide range of cooking tasks.
• The extra large burner bis the maximum
output burner. Like the other burners, it can be
used for most everyday cooking tasks. This
burner is also designed to quickly bring large
amounts of liquid to a boil. The special
UltraHeat+ setting is designed for use with
cookware 10 inches or larger in diameter. The
extra large dual burner can also be used on LO
to simmer.
eExtra Large Burner only
Selecting Flame Size
NEVER let the flames extend up the sides of the
cookware.

10 OPERATION
Watch the flame, not the knob, while reducing the
heat. When fast heating is desired, the flame size
on a gas burner should match the cookware used.
Flames larger than the bottom of the cookware will
not result in faster heating of the cookware and
could be hazardous.
Cookware
• Aluminum
Medium-weight cookware is recommended
because it heats quickly and evenly. Most of the
foods brown evenly in an aluminum skillet. Use
sauce pans with tight fitting lids when cooking
with minimum amounts of water.
• Cast-Iron
If heated slowly, most skillets will give
satisfactory results.
• 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 recommends.
•Enamelware
Under some conditions, the enamel of some
cookware may melt. Follow cookware
manufacturer’s recommendations for cooking
methods.
•Glass
There are two types of glass cookware - those for
oven use only and those for top of the range
cooking (saucepans, coffee and teapots). Glass
conducts heat very slowly.
• 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 gas
ranges.
Using a Wok
Do not use a wok support ring. Placing the ring
over the burner or grate may cause the burner to
work improperly, resulting in carbon monoxide
levels above allowable standards.
This can be a health hazard.
Use a 14 inch or smaller flat bottom wok. Make
sure the wok bottom sits flat on the grate.
Woks are available at a local retail store.
Only a flat-bottomed wok should be used.
Stove-Top Grills
Do not use stove top grills on the surface burners.
Using the stove top grill on the surface burner will
cause incomplete combustion and can result in
exposure to carbon monoxide levels above
allowable current standards.
This can be a health hazard.
Using the Griddle
The enamel-coated griddle provides an extra -
large cooking surface for meats, pancakes or other
food usually prepared in a frying pan or skillet.
NOTE
• The griddle will discolor over time as it becomes
seasoned with use.
How to Place the Griddle
• The griddle can only be used on the left side
grate.
• The griddle must be properly placed on the
grate.
• When the correct side is facing the front, the
tabs on the underside of the griddle sit properly
on the prongs of the grate to keep the griddle
from moving.
