A fuel control system, a control unit therefor and methods of making the same are provided, the system comprising a control unit that reduces the length of the warm-up time period of an igniter in subsequent successive burner cycles in which ignition is successful until the control device detects an increase in the length of the flame detecting time period in that particular successive burner cycle over the length of the flame detecting time period on a previous burner cycle at which time the control device then increases the length of the previously reduced warm-up time period a certain amount. |
