<p>The automatic flame controller has a detection electrode connected to a rectifying diode. The controller has current rectifier and an ignition system and flame controller, operated through a valve acting on the rectified current. When the flame has failed and the rectified current is zero, the flame is re-ignited at least once before shutting off the fuel. The control system has an ignition circuit, a power circuit, a flame detection and a flame failure circuit. The circuits may be programmed for different frequencies.</p> |
