Flame Safety Devices

Flame safety devices (or flame failure devices) work by stopping the gas supply to the cooktop if the flame goes out.

The flame safety device works by utilising a thermocouple heated by the burner flame. The thermocouple generates a small electrical current which is connected to a small electromagnetic valve in the gas supply line. When the the thermocouple is hot, the valve continues to stay open. When the flame is extuinguished (by a draught or gust of air) the thermocouple goes cold and the electrical current no longer passes through it. The valve is then turned off automatically because the electromagnet has had its electrical current shut off.
