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]
An alternative to the pilot light is a system to create a high voltage electrical arc or spark between two electrodes, in order to light the gas flowing to the burner. Fail-safe design for such a system requires the burner flame to be detected by passing an electric current through the flame, which is received by the flame rectification circuit ...
