Abstract

A control system for use in combination with any combustion type heating device to provide a fail-safe safety ignition system. A voltage source, circuit breaker, igniter, electrically actuated fuel source control means and serially connected ignition sensing means, of a material having a high positive temperature coefficient of electrical resistance, are incorporated in the system. The current due to varying resistance of the sensing means will develop from a high initial value to a lower average normal running current value upon satisfactory ignition. The system parameters are selected to automatically disconnect the fuel source in the event of a failure in the combustion cycle. The circuit which includes the sensing means may also include a temperature indicating device. [US3663150A]
