If none of the igniters are clicking, turn off theburner and check the circuit panel for a blown fuse or a tripped circuit breaker. If only one burner is not lighting,its igniter or burner ports need to be cleaned. See section ‘Care and maintenance’ for instructions.BURNER EFFICIENCY:It is necessary to keep the burner ports and the igniters clean for proper lighting and efficient performance. Theburner flame should burn completely around the burner with no excessive noise or lifting.

If youare cooking with a large amount of liquid a slightly larger flame can be used.BURNER GRATES:The cast iron burner grates are fully porcelain coated for long life and rust prevention. Hi-Temperaturecushions allow the grate to rest softly on the cooktop without scratching.
