摘要： An electrical system for igniting gas burners to provide safety features as well as an efficient and dependable means for igniting the gas flame. Gas is ignited by a glow coil and a sensor- or probe-type resistance unit imposes a control function to turn off the gas supply if the burner is not ignited within a predetermined time period. The sensor also closes the gas valve whenever the sensor is no longer heated.
