Abstract
A gas burner control system includes an electrical resistance igniter, gas valve means, and a microcomputer and related circuitry. The microcomputer and related circuitry control energizing of the igniter in such a manner so that the igniter, after successive ignition attempts, will eventually, in response to a learning routine, be heated to a desired ignition temperature. The microcomputer and related circuitry also control operation of a circulator blower in response to burner flame and provide for numerous checks on the integrity of system components.
