Abstract
An electronic gas control apparatus including a variable flow valve, an igniter, a flame sensor, and an electronic controller is provided. The valve has a flow range that equals or exceeds a required flow range for any one of the types of gas suitably combusted by the burner. The electronic controller is operably coupled to each of the valve, the igniter, and the sensor. The electronic controller is configured to activate the igniter, to receive a flame status signal from the sensor, and to recognize a position of the valve when the flame status signal indicates a flame at the burner. As such, the electronic controller is calibrated for the gas, line-pressure, jet and burner configuration being used.
