Warning

Do not store or use gasoline, liquid propane cylinder or other flammable vapors and liquids in the vicinity of this appliance. The installation and service of your rangetop must be performed by a qualified installer, an approved service agency or the gas supplier. Gas appliances can cause minor exposure to four of these substances, namely benzene, carbon monoxide, formaldehyde and soot, caused primarily by the incomplete combustion of natural gas fuel. When operating your range on natural gas, the flames from the burners should be blue in color. In addition, the flames should be stable, free of yellow tipping, excessive noise and lifting. However, this yellow tipping should be restricted to the primary flame kernels only. Properly adjusted burners, indicated by a bluish rather than a yellow flame, will minimize incomplete combustion. Exposure to those substances can be minimized by venting with an open window or use of a ventilation fan or hood.

RANGETOP OPERATION

Surface Burner Ignition

To light the surface burners, push and turn the appropriate control knob counterclockwise to a “Hi” position. You will hear a clicking noise – the sound of the electric spark igniting the burner. Once burner ignition has been achieved, turn the burner control knob to adjust the flame size. If the knob stays at “Hi”, it will continue to click.

NOTE: When one burner is turned to the “Hi” position, all the burners will spark. Do not attempt to disassemble or clean around any burner while another burner is on. Do not touch any burner cap, burner base, or igniter while the igniters are sparking.

Heat Settings:

Hi	Ignites the burners.
Low	Melting large quantities.
Hi	Boiling liquid quickly, deep frying.

Rangetop Operation

Simmer and Boil

A smaller flame will give the best simmer results. Small flames offer precise cooking performance for delicate foods, keeping food warm, melting chocolate or butter, and for cooking that need to cook over low heat for a long time.
The highest (larger) flame settings provide the maximum heat that is available on your range. This setting should be used for heavy cooking loads such as water boiling and pasta cooking.

Flame Size

When you select the flame size, watch the flame when you turn the knob.
Any flame larger than the bottom of the cookware is wasted.
The flame should be steady and blue in color. Foreign material in the gas line may cause an orange flame during the initial operation.

Power Failure

If the gas does not ignite within four seconds, turn off the valve and allow at least five minutes for any gas to dissipate. Repeat the lighting procedure.
If the power fails, the surface burners can be lighted manually. Hold a lighted match near a burner and turn the knob counterclockwise to “HI”. After burner lights, turn knob to set.

Rangetop

To prevent the range top from discoloring or staining, clean the cooktop after each use, and wipe up acidic or sugary spills as soon as the cooktop has cooled.
The sealed burners of your range are not secured to the rangetop and are designed to be removed. Boilovers or spills will not seep underneath the rangetop. The burners should be cleaned after each use.

Rangetop Operation
