The high-pressure gas entering customer piping systems in some cases resulted in high pilot light flames which ignited fires in buildings; while in other cases, the pilot light flames were blown out, allowing gas to escape within the buildings. Of the 167 buildings affected by the overpressure, 12 were destroyed and 32 had moderate to heavy ...
A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. Originally a pilot light was kept permanently alight, but this wastes gas. Now it is more common to light a burner electrically, but gas pilot lights are still used when a high energy ignition ...
Pilot lights were withdrawn because their continual small flame represented a waste of fuel. [1] Pilot lights required their own FSD, typically a thermocouple which held the valve open. [2] Regular testing of FSD is a part of routine maintenance for gas appliances. [3] Other safety devices may be fitted in addition to an FSD.
Gas stoves today use two basic types of ignition sources, standing pilot and electric. [21] A stove with a standing pilot has a small, continuously burning gas flame (called a pilot light) under the cooktop. [21] The flame is between the front and back burners. When the stove is turned on, this flame lights the gas flowing out of the burners.
Depending on the age of the system, forced-air gas furnaces use either a pilot light or a solid-state ignition system (spark or hot surface ignition) to light the natural gas burner. [3] The natural gas is fed to buildings from a main gas line.

In the pilot trial, the pilot solenoid is opened and the ignition transformer is turned on. The fuel is lit to make sure the pilot flame stays lit. There is a flame detection device that will shut down the fuel valve if the flame fails or goes out
