pilot burner
Standing starter flame
A pilot burner is a small auxiliary flame that burns continuously in gas appliances such as furnaces, water heaters, and stoves.
Its purpose is to ignite the main burner when the appliance calls for heat.
Traditional pilot burners stay lit around the clock, though many modern appliances have replaced them with electronic ignition systems that are more energy-efficient.
The technician relit the pilot burner after the gas was restored.
