A safety arrangement in a gas-operated apparatus, such as an absorption refrigerator, having a safety device that controls the gas system and, when required, automatically reignites the flame of the gas burner that has become extinguished. The system has a thermostat that is connected to a switch for opening a gas valve when it is necessary to supply gas to the burner. A filament or igniter is also provided which is arranged adjacent to the burner and has a switch which breaks the circuit to the gas valve when a sensor or flame detector at the burner is exposed to a flame.
