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.
