Flame Carryover Problems

During ignition, the flame must travel uninterrupted from one burner to the rest of the burners.

Causes:

•Carryover “wing” on burner is plugged with insects or debris

•Improper gap setting on wings

•Incorrect gas pressure

The burner wing has a specified gap (typically 0.025" +/– .002"), which must carry gas and a small flame to allow flame carryover from one burner to the next. Check the gap settings on all burners.
