ABSTRACT:
A control device for regulating delivery of fuel and an associated method of use is disclosed. The control device includes an inlet, an electromagnetic safety valve, having a thermocouple connection, a control valve, wherein the electromagnetic safety valve selectively allows fuel to flow from the inlet to the control valve through the electromagnetic safety valve when the thermocouple connection is heated, an actuator valve, a main valve having a pressure responsive device, having a first side and a second side and including an outlet chamber, a regulator valve having a sensing port and an outlet. There is an adjustment mechanism associated with the control valve that can also direct fuel into a pilot assembly.
