Abstract

A primary control unit and ignitor using a microprocessor for fuel and ignition control and intelligent flame monitoring of a fuel burning device such as kerosene fired heaters. The control unit will function with a voltage supply ranging from 30 to 264 volts, 50 or 60 hertz. It has intermittent ignition resulting in reduced electromagnetic interference and longer spark plug life. The ignitor circuit is isolated from the DC power supply to prevent any common mode electromagnetic interference.
