• Make sure your cooktop is correctly installed and adjusted by a qualified service technician
or installer for the type of gas (natural or LP) you will use. For your cooktop to utilize LP gas,
the installer must replace the 4 or 6 surface burner orifices with the provided LP orifice set,
and reverse the GPR adapter. Furthermore, the bypass in burner valve will need to be
adjusted. These adjustments must be made by a qualified service technician in accordance
with the manufacturer's instructions and all codes and requirements of the authority having
jurisdiction.
• The qualified agency performing this work assumes the gas conversion responsibility.
• Installation of this cooktop must conform with local codes or, in the absence of local codes,
with the National Fuel Gas Code, ANSI Z223.1/NFPA.54, latest edition. In Canada,
installation must conform with the current Natural Gas Installation Code, CAN/CGA-B149.1,
or the current Propane Installation Code, CAN/CGA-B149.2, and with local codes where
applicable. This cooktop has been design-certified by ETL according to ANSI Z21.1, latest
edition, and Canadian Gas Association according to CAN/CGA-1.1, latest edition.

SAFETY & WARNINGS
COOKTOP SAFETY (CONTINUED)
WARNING
To reduce the risk of fire, electric shock, personal injuries, and/or death, observe the
following precautions.
• If foods are flamed, they should only be flamed under a ventilation hood that is on.
• Before removing or changing cookware, turn off the burners.
• Remove food and cookware immediately after cooking.
• Before removing any parts of the burner for cleaning, make sure the cooktop is off and
completely cool.
• After cleaning the burner spreader, make sure it is completely dry before re-assembling.
• To avoid carbon monoxide poisoning, do not pour water into the cooktop well while
cleaning.
• To avoid cookware discoloration, deformity, and/or carbon monoxide poisoning, do not use
cookware that is substantially larger than the grate.
• Make sure cookware handles are turned to the side or rear of the cooktop and not over
other surface burners.
• Stand away from the cooktop while frying.
• Always heat frying oils slowly, and watch as they heat. If you are frying foods at high heat,
carefully watch during the cooking process. If a combination of fats or oils is to be used
during frying, mix them together before heating.
• Use a deep-fryer thermometer whenever possible. This prevents overheating the fryer
beyond the smoking point.
• Use a minimum amount of oil when shallow pan-frying or deep-frying. Avoid cooking un-
thawed food or food with excessive amounts of ice.
• Before moving cookware full of fats or oils, make sure it has completely cooled.
• To prevent delayed eruptive boiling, always allow heated liquids to stand at least 20
seconds after you have turned off the burner so that the temperature in the liquid can
stabilize.
•In the event of scalding, follow these first aid instructions:
1.) Immerse the scalded area in cool or lukewarm water for at least 10 minutes.
2.) Do not apply any creams, oils, or lotions.
3.) Cover with a clean, dry cloth.
• If a power failure occurs or the electric ignition fails to operate, do not use matches or
lighters to ignite the burners. This may cause a fire or physical burns.
• Do not place and use electric-powered cooking devices such as IH rice cookers or desktop
cooking heaters on top of your cooktop. Electromagnetic forces from these appliances may
cause the cooktop to malfunction.
