Cooktop Use
Read the instructions before installing or using this appliance.
• This appliance shall be installed in accordance with the regulations in force
and only used in a well-ventilated space.
• The use of a gas-cooking appliance results in the production of heat
and moisture in the room in which it is installed. Ensure that the kitchen is
well ventilated: keep natural ventilation holes open or install a mechanical
ventilation device (mechanical extractor hood).
• Prolonged intensive use of the appliance may call for additional ventilation,
for example opening of a window, or more effective ventilation, for example
increasing the level of mechanical ventilation where present.
• Burners should be operated only when covered by cookware. Burner flames
not covered by cookware present a risk of fire or clothing ignition.
• Never let flames extend beyond the sides of the cookware. Failure to comply
may result in serious injury.
• Always turn off the surface burners before removing cookware. All surface
burners should be turned off when you are not cooking.
• When removing hot cookware from the burner, be sure to lift it high enough
to not come in contact with the control knobs. Hot cookware coming into
contact with the control knobs could cause damage, such as melting or
warping.
• 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 operate the burner for an extended period of time without cookware
on the grate. The finish on the grate may discolor or chip without cookware to
absorb the heat.
• Do not attempt to disassemble any burner while another burner is on.
Damage to the product may occur.
• Be sure the burners and grates are cool before you place your hand, a pot
holder, or cleaning materials on them.
35
Using the Cooktop Burners
IMPORTANT: Make sure all cooktop burners are properly installed.
1. To ignite a burner, push down on the burner control knob and turn it
counter-clockwise towards the “HI” position. The clicking sounds indicate the
system is igniting.
2. After the cooktop burner lights, release and turn the control knob between
HI, Med, and LO to adjust the flame level.
NOTE: Flame failure safety device (Thermocouple) - Once the flame is lit,
hold the control knob depressed for about 3-4 seconds until the device
keeps the burner automatically lit. If the burner fails to ignite, wait one
minute for the gas to dissipate before attempting to reignite.
3. To turn off the burner, turn the control knob to the off "." position.
Power Failure
In case of prolonged power failure, the surface burners can be lit manually
with a match. Using extreme caution, hold a lit match near the ports beneath
the surface burner cap, then push down on the burner control knob and slowly
turn it counter-clockwise towards the “Hi” position. Once lit, release and turn
the control knob to adjust the flame level, and surface burner will continue to
operate normally.
NOTES:
In the case of unintentional flame extinguishing, the safety valve intervenes by
shutting off the gas to the burners.
The electric igniter must not be actuated for longer than 15 seconds. Should
the burner not light, or should the burner be unintentionally turned off,
immediately close the burner, and wait at least 1 minute before repeating.
Once ignited, adjust the flame as desired.
For lower gas consumption and a better result, use saucepans with a diameter
matching the diameter of the burner, to avoid the flame coming up around the
sides of the saucepan. See the Container Table. Use only flat-bottomed pans.
As soon as liquid starts to boil, turn the flame down to a level sufficient to
maintain boiling.

Match Pan Diameter to Flame Size
The flame should be the same size as the bottom of the pan or smaller. Do not
use small pans with high flame settings as the flames can lick up the sides of
the pan. Oversize pans that span two burners are placed front to rear, not side
to side.
Use Balanced Pans
Pans must sit level on the cooktop grate without rocking. Center the pan over
the burner.
Use A Lid That Fits Properly
A well-fitting lid helps shorten the cooking time. Flat, heavy bottom pans pro-
vide even heat and stability.

Cooktop Care
Cleaning
IMPORTANT: Before cleaning, make sure all controls are off and the cooktop
is cool. Always follow label instructions on cleaning products. Soap, water, and
a soft cloth or sponge are suggested first, unless otherwise noted. Do not use
abrasive cleaning products.
Control Knobs
• To remove the knobs, be sure the knobs are in the off "." position.
• Pull knobs straight away from control panel to remove.
Cleaning Recommendation:
• The knobs should be cleaned with soap and water.
• Do not clean knobs in the dishwasher or use abrasive cleaners or steel
wool.
• Do not remove the seals under the knobs.
Burner Grates
• To avoid chipping, do not bang grates against each other or hard surfaces,
such as cast iron cookware. Although the grates are durable, they will gradually
lose their shine due to exposure to high temperatures.
Cleaning Recommendation:
• Soap and Water: Use a nonabrasive plastic scrubbing pad and mildly
abrasive cleanser, soap, and water.
• Dishwasher: The grates may be cleaned in the dishwasher. Remove any
burnt-on food prior to placing the grates in the lowest rack in the dishwasher.
Burner Caps
• Do not place caps in the dishwasher or reassemble caps on burners when
wet.
Cleaning Recommendation:
• Use a nonabrasive plastic scrubbing pad and mildly abrasive cleanser, soap,
and water.
38
Burner Base
• The holes in the burner bases must be kept clean for proper ignition and a
complete, even flame. Spillovers should be cleaned immediately since they can
clog the openings in the burners.
IMPORTANT: Before cleaning, make sure all controls are off " . " and the
cooktop is cool.
Cleaning Recommendation:
• Remove the burner cap from the base. Clean the burner cap with hot soapy
water, and then rinse it.
• Remove the burner base and clean the gas tube opening under the base.
• Clean clogged burner ports with a straight pin, needle, or small-gauge wire
as shown. Do not use a wooden toothpick or clean in the dishwasher.
• Gently clean the igniter with a damp cloth.
Stainless Steel Cooktop Surface
• Food spills containing acids, such as vinegar and tomato, should be cleaned
as soon the cooktop is cool. These spills may affect the finish.
• Do not use scouring pads, abrasive cleaners, cooktop cleaner, steel wool
pads, gritty washcloths, or abrasive paper towels.
Cleaning Recommendation:
• For best results, use a soft cloth or non-scratch sponge.
• Rub in direction of the grain to avoid damaging the surface.
• Use stainless steel or all-purpose cleaner.
Porcelain Enamel Cooktop Surface (On Some Models)
Cleaning Recommendation:
• Use a nonabrasive scrubbing pad and glass cleanser or a mild liquid cleaner.
