Cookware

This information will help you save energy and avoid damaging your cookware.

Suitable cookware

Only use cookware of a suitable size. The cookware must not overhang the edge of the cooktop.

Burner	Minimum diameter of the cookware base	Maximum diameter of the cookware base
Extra large burner	8⅔" (22 cm)	11¾" (30 cm)
Large burner	7¾" (20 cm)	10¼" (26 cm)
Medium burner	5½" (14 cm)	7¾" (20 cm)
Small burner	4¾" (12 cm)	6¼" (16 cm)

Cookware recommendations

• Aluminum or copper bottomed pans conduct heat evenly.
• Steel pans, if not combined with other metals, may cook unevenly.
• Cast-iron cookware absorbs heat slowly and cooks more evenly at low to medium settings.
• Flat heavy bottom pans provide even heat and stability.
• DO NOT USE pans that are thin, warped, dented or ridged as they heat unevenly.

Using cookware

The selection and positioning of the cookware affects the safety and energy efficiency of your appliance.

Flammable objects may ignite.

• Maintain a distance of at least 2½" (50ºmm) between the cookware and flammable objects.

Note: When using certain pots or pans, a slight and temporary deformation of the steel cooking surface may occur. This is normal and does not affect the functionality of the appliance.

	Ensure that the size of the cookware is suitable for the burner size. Never use small cookware on large burners. Ensure that the flame does not touch the sides of the cookware.
	Do not use deformed cookware. Deformed cookware is not stable on the cooktop and may tip over. Use cookware with a thick, flat base.
	Do not cook without a lid. Ensure that the lid does not move. When cooking without a lid, a large amount of the energy will escape.
	Position the cookware in the middle of the burner, otherwise it may tip over. Do not position large cookware on the burners close to the controls. The controls may be damaged due to overheating.
	Place the cookware on the burner grates. Never place the cookware directly on the burner. Before using the appliance, ensure that the burner grates and the burner caps are positioned correctly.
	Handle the cookware that is on the cooktop carefully. Do not bang on the cooktop. Do not place heavy weights on the cooktop.
	Never use multiple burners to heat up cookware, such as roaster, pan, grill stone. The build-up of heat that results from this will damage the appliance.
	When cooking with a wok, use the wok ring. Place the wok ring over the wok burner onto the burner grate. Ensure that the wok is stable on the wok ring when you are cooking.

Have the installer show you where the gas shut-off valve is located.
If a burner goes out and gas escapes, open windows and doors. Wait until gas dissipates before using the appliance.
If you smell gas, your installer has not done a proper job of checking for leaks. If the connections are not perfectly tight, you can have a small leak and, therefore, a faint smell. If you smell gas, immediately shut off the unit and contact an authorized service provider to diagnose the issue. Read the WARNING about gas smell.

Keep the igniter ports clean for proper lighting performance of the burners. It is necessary to clean these when there is a boilover or when the burner does not light even though the electronic igniters click.
For proper burner performance, keep igniters clean and dry.

All igniters spark when any single burner is turned on.

• Do not touch any of the burners when the cooktop is in use.

To prevent flare-ups all grates must be properly positioned on the cooktop whenever the cooktop is in use. Each of the feet must be placed into the corresponding dimples in the cooktop.

To prevent flare-ups do not use the cooktop without all burner caps and all burner grates properly positioned.

Use this appliance only for its intended use as described in this manual.

• NEVER use this appliance as a space heater to heat or warm the room. Doing so may result in carbon monoxide poisoning and overheating the appliance.

The burning of gas cooking fuel can create small amounts of carbon monoxide, benzene, formaldehyde and soot. To minimize exposure to these substances the burners should be adjusted by a certified installer or agency to ensure proper combustion.
