For gas appliances, a flame supervision device (FSD) – alternative name: flame failure device (FFD) – is a general term for any device designed to stop flammable gas going to the burner of a gas appliance if the flame is extinguished.

A hot plate can be used as a standalone appliance, but is often used as a substitute for one of the burners from an oven range or a kitchen stove.
Often, a gas stove will have burners with different heat output ratings. For example, a gas cooktop may have a high output burner, often in the range 3 to 6 kilowatts (10,000 to 20,000 BTU/h), and a mixture of medium output burners, 1.5 to 3 kW, and low output burners, 1 kW or less.

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 ...
