Abstract
A spark ignition system for a heater-type ignitor is disclosed. Current through the ignitor is transformed into a voltage which is utilized to operate a timing circuit which, in turn, causes operation of a valve permitting the flow of fuel to a burner. Operation of the valve can occur only after the expiration of a pre-determined period of time during which the voltage applied to the ignitor and the current passing therethrough are continuously monitored thus ensuring that the ignitor has reached the ignition temperature of the fuel before the valve is permitted to open.
