SAFETY DURING USE (cont.)
• Overheated fats and oils catch fire quickly. You should supervise cooking when
preparing foods in fat or oil.
• Turn off all burners after use.
• Never place combustible items on the cooktop.
• Never keep any combustible items or aerosol cans in a drawer located under the
cooktop.
• 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.
• Clean the appliance regularly to keep all parts free of grease that could catch fire.
Exhaust fan ventilation hoods and grease filters should be kept clean. Do not allow grease
to accumulate on hood or filter. Greasy deposits in the fan could catch fire. Refer to hood
manufacturer's instructions for cleaning.
• Use Proper Pan Sizes. Do not use 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 range can ignite. Use pans with handles that can be easily grasped and
remain cool.
• NEVER let the flames extend up the sides of the cookware for safe handling of
cookware. Flames larger than the bottom of the cookware will not result in faster heating of
the cookware and could be hazardous.
• Do not place any object on or near the gas knob control area.
• Do not let pot holders come in contact with open flame when lifting cookware off
burners.
• Do not use a towel or other bulky cloth in place of a pot holder.
• Always the turn knob to the “LITE” the position when igniting the top burners and
make sure the burners have ignited.
• Glazed cooking utensils: Only certain types of glass, glass/ceramic, ceramic,
earthenware, or other glazed utensils are suitable for cooktop service without
breaking due to the sudden change in temperature. Check the manufacturer’s
recommendations for cooktop use.
• Ventilating hood: The ventilating hood above your cooking surface should be
cleaned frequently, so the grease from cooking vapors does not accumulate on the
hood or filter.

PROVIDE ADEQUATE GAS SUPPLY
• This cooktop is designed to operate at a pressure of 5”of water column on natural gas or 10” of
water column on LP, propan or butane gas.
• Make sure you are supplying your cooktop with the type of gas for which it is designed.
• This cooktop is convertible for use on natural or propane gas. When using this cooktop on LP gas,
conversion must be made by a qualified LP installer before attempting to operate the cooktop on that gas.
• For correct operation, the pressure of natural gas supplied to the regulator should between 5” and
13” of water column.
• For LP gas, the pressure supplied must be between 10”and 13”of water column.
• When checking for correct operation of the regulator, the inlet pressure must be at least 1” more
than the operating -manifold- pressure as given above.
• The pressure regulator located at the inlet of the cooktop manifold must remain in the supply line
regardless of whether natural or LP gas is being used.
• A flexible metal appliance connector used to connect the cooktop to the gas supply line must have
an I.D. of 5/8” and can be 3 feet in length easily for installation. In Canada, flexible connectors
should be single wall metal connectors less than 6 feet in length.
CONNECT THE COOKTOP TO GAS
• Shut off the main gas supply valve before removing the old cooktop and leave it off until the new
hook-up has been completed. Don’t forget to relight the pilot on other gas appliances when you turn
the gas back on.
•
Because hard piping restricts movement of the cooktop, the use of a CSA International-certified flexible
metal appliance connector is recommended unless local codes require a hard-piped connection.
• Never reuse an old connector when installing a new cooktop. If the hard piping method is used, you
must carefully align the pipe; the cooktop cannot be moved after the connection is made.
• To protect gas leaks, put pipe joint compound on, all male -external- pipe threads.
❶Install a manual gas line shut-off valve in the gas line in an easily accessed location outside of the
cooktop. Be sure everyone operating the cooktop knows where and how to shut off the gas
supply to the cooktop.
❷Install male 1/2” flare union adapter to the 1/2” NPT internal thread at inlet of pressure regulator.
Use a backup wrench on the pressure regulator fitting to prevent damage.
❸Install male 1/2” or 3/4” flare union adapter to the NPT internal thread of the manual shut-off valve,
taking care to back-up the shut-off valve to keep it from turning.
❹Connect flexible metal connector to the adapter on the cooktop. Position cooktop to permit
connection at the shut-off valve.
WARNING: DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.
Disconnect the cooktop and its individual shut-off valve from the gas supply piping system
during any pressure testing of that system at test pressures more than 1/2psig(3.5kPa).
Isolate the cooktop from the gas supply piping system by closing its individual shut-off valve
during any pressure testing of the gas supply system at test pressures equal to or less than 1/2
psig(3.5kPa)

prong wall receptacle.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE THIRD (GROUND)
PRONG FROM THE POWER CORD.
• A word about Ground Fault Circuit Interrupters-Ground Fault Circuit Interrupters are not required or
recommended for gas range receptacles. Ground Fault Circuit Interrupters are devices that sense
leakage of current in a circuit and automatically switch off power when a threshold leakage level is
detected. These devices must be manually reset by the customer. The National Electrical Code
requires the use of Ground Fault Circuit Interrupters in kitchen receptacles installed to serve
countertop surfaces. Performance of the cooktop will not be affected if it is operated from a Ground
Fault Circuit Interrupters protected circuit but occasional nuisance can occur.
CAUTION: The customer should have the circuit checked by a qualified technician to
make sure the receptacle is correctly grounded.
• DO NOT use an adapter plug because disconnecting of the power cord places undue strain on the
adapter and causes eventual failure of the adapter ground terminal.
• The customer must have the two-prong wall receptacle replaced with a three-prong (grounding)
receptacle by a qualified technician before using this cooktop.
• The installation of appliances designed for mobile home installation should conform with the
Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280 (formerly the
Federal Standard for Mobile Home Construction and Safety, Title 24, HUD, Part 280) or, when such
standard is not applicable, the Standard for Manufactured Home Installations, latest edition
(Manufactured Home Sites, Communities and Set-Ups), ANSI A225.1, latest edition, or with local
codes. In Canada, mobile home installation must comply with the current CAN/CSA Z240/MH
Mobile Home Installation Code.
SEAL THE OPENINGS
• Seal any openings in the wall behind the cooktop and in the floor of the cabinet when hookups are
completed.

which could cause you to knock over hot cookware.
• The medium (left front & rear) and the large (right front) burners are the primary burners for most cooking.
These general-purpose burners can be turned down from “HI” to “LO” suit a wide range of cooking needs.
• The extra large burner (center) is the maximum output burner. Like the other four burners, it
can be turned down from “HI” to “LO” for a wide range of cooking applications.
• This burner is also designed to quickly bring large amounts of liquid to a boil. It
has a special “SUPER BOIL” setting designed to be used with cookware 10
inches or larger in diameter.
• The middle burners are for large pots/pans or for use with the griddle.
• The extra large burner(daul) can be also turned down to “LO” for a low simmer
setting almost like the small burner.
SEALED GAS BURNERS
Your cooktop has five sealed gas burners. They offer convenience,
cleanability and flexibility to be used in a wide range of cooking
applications. The smallest burners are in the right rear this burner can
be turned. These burners can be turned down to “LO” for a very low
simmer setting. They provide precise cooking performance for delicate
foods such as sauces or food that require low heat for a long cooking
time.
IN CASE OF POWER FAILURE
In case of a power failure, you can light the gas surface burners on your 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.

USING THE GAS SURFACE BURNERS
HOW TO SELECT FLAME SIZE
• NEVER let the flames extend up the sides of the cookware for safe
handling of cookware.
• Watch the flame, not the knob, as you reduce heat. When fast heating
is desired, the flame size on a gas burner should match the cookware
you are using.
• 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 saucepans 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 hazardous to your health.
• We recommend that you use a 14-inch or smaller flat-bottomed wok.
Make sure the wok bottom sits flat on the grate. They are available at
your local retail store.
• Only a flat-bottomed wok should be used.
STOVE-TOP GRILLS
• Do not use stove top grills on your surface burners. If you use the
stove top grill on the surface 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.

CARE AND CLEANING
Make sure electrical power is off and all surfaces are cool before cleaning any part of the
cooktop.
SEALED BURNER ASSEMBLIES
• Turn all controls OFF before removing the
burner parts.
• The burner grates, caps, and burner heads can
be lifted off, making them easy to clean.
• The electrodes are not removable.
The electrode of the burner is exposed when the burner head and cap are removed. When one
burner is turned to “LITE”, all the burner spark.
Do not attempt to disassemble or clean around any burner while another burner is on.
An elecctric shock may result, which could cause you to knock over hot cookware.
