The method and apparatus provides a controller (which might comprise a microprocessor) that can control gas flow to a pilot burner in fluid communication with a manual pilot valve and an automatic pilot valve. The exemplary embodiments can comprise a selectable input device that can open the manual pilot valve to allow gas flow to the pilot burner. A pilot flame can then heat one or more thermal detection devices in thermal communication with the pilot burner, wherein the one or more thermal detection devices can output a variable voltage potential to the controller. The controller can then open the automatic pilot valve to maintain gas flow to the pilot burner after the manual pilot valve has been closed. In an exemplary embodiment, the only voltage potential used to power the controller is supplied by the one or more thermal detection devices.
