Ultra Power™ Dual-Flame Burner
Professional Burner
Simmer/Melt Burner
Electronic Ignition System
Initial lighting and gas flame adjustments
Cooktop burners use electronic igniters in place of standing
pilots. When the cooktop control knob is turned to any position,
the system creates a spark to light the burner. This sparking
continues until the flame is lit or the knob is turned to OFF.
Check Operation of Cooktop Burners
Push in and turn each control knob to the Lite position.
The surface burners and grill flames should light within
4 seconds. The first time a burner is lit, it may take longer
than 4 seconds to light because of air in the gas line.
After verifying the proper burner operation, turn the control
knobs to OFF.
If burners do not light properly:
■Turn cooktop control knob to the Off position.
■Check that the cooktop is plugged in and the circuit breaker
has not tripped or the fuse has not blown.
■Check that the gas shut-off valves are set to the
open position.
■Check that burner caps are properly positioned on
burner bases.
Repeat start-up. If a burner does not light at this point, contact
your dealer or authorized service company for assistance.
If you need Assistance or Service:
Please reference the “Assistance or Service” section of the Use
and Care Guide or contact the dealer from whom you purchased
