Abstract

See full text

A direct ignition gas burner control system includes an igniter, two serially-arranged gas valves for controlling the flow of gas to the burner, and a microcomputer and related circuitry for controlling energizing of the igniter and valves. The microcomputer and its related circuitry provide for numerous options in system functions and for numerous checks on the integrity of the system components.
