IMPORTANT: Do not obstruct the flow of combustion and ventilation air around the burner grate
edges.
Burner cap and gas spreader
Always keep the burner cap and gas spreader in place when using a surface burner. A
clean burner cap and spreader will help prevent poor ignition and uneven flames. Always
clean the part after a spillover and routinely remove and clean according to the “Care and
Maintenance” section.
Burner base and orifice
Gas must flow freely through the orifice to light properly. Keep this area free of soil and
do not allow spills, food, cleaning agents or any other material to enter the orifice or the
area around it.
Protect it during cleaning.
