Abstract
A fuel control system for a main burner having a dual rate pilot burner and a control device for providing a standby flame flow of fuel to the pilot burner when the output temperature effect of the main burner is above the temperature setting of the control device and for providing a large heater flame flow of fuel to the pilot burner when the output temperature effect of the main burner is below the temperature setting of the control device so that only the heater flame will cause a main flow of fuel to the main burner for a heating operation thereof. A diverter valve is provided for diverting the heater flame flow of fuel from the dual rate pilot burner to another pilot burner so that the main flow of fuel to the main burner will cease even though the output temperature effect of the main burner is below the temperature setting of the control device, the diverter valve being controlled by a timer or the like to provide a "cook and hold" feature of the system.
