Brass Burner Base Burner Cap Ports Figure 7: Star® Burner Components Automatic Re-Ignition If any one or more burners or grill blow out, the electronic igniter automatically activates to re-light the flame. Do not touch the burners when the igniters are active. Important For proper combustion do not use the cooktop without the burner grates in place. There is a slight sound associated with gas combustion and ignition. This is a normal condition. On cooktops using propane gas (LP), a slight "pop" sound may be heard at the burner ports a few seconds after the burner has been turned off. Power Failure • In the event of a power failure, only the standard burners can be manually lit. It is necessary to light each one individually. If the cooktop is being used when the power failure occurs, turn all knobs to the OFF position. • The standard burners can be lit by holding a match at the ports and turning the control knob to the position. Wait until the flame is burning all around the burner cap before adjusting the flame to the desired height. • The ExtraLow burners cannot be used during a power failure. Be sure to turn them off. • If the ExtraLow burner is on when a power failure occurs, it cannot be turned back on until the knob is first turned off. • The griddle or grill cannot be used during a power failure. • If you smell gas, refer to safety precautions in the front of this manual. WARNING In the event of a power failure, all knobs are to be turned to the OFF Position. Only the standard burners can be lit manually. Flame Height • The correct flame height depends on 1) size and material of pan being used; 2) food being cooked; and 3) amount of liquid in the pan. • Never extend the flame beyond the base of the pan. • Use a low or medium flame for pan materials that conduct the heat slowly, such as porcelain coated steel or glass-ceramic.
