Patent ID: 8757202

Claim:
A dual fuel heating source comprising: a dual pressure regulating unit for regulating the pressure of either of two different fuels at different pressures, comprising: a first main body at least partially defining a first flow path and a second flow path; a first regulating unit outlet port; and a second regulating unit outlet port; wherein the first flow path ends in the first regulating unit outlet port and the second flow path ends in the second regulating unit outlet port; a dual entry valve unit comprising: a second main body at least partially defining a third flow path and a fourth flow path; a first valve unit inlet; a second valve unit inlet; a first valve unit outlet port; and a second valve unit outlet port; and an exit valve comprising: a third main body at least partially defining a fifth flow path, a sixth flow path, a seventh flow path and an eighth flow path; a first exit valve inlet; a second exit valve inlet; a first exit valve outlet port; a second exit valve outlet port; a third exit valve outlet port; and a fourth exit valve outlet port; wherein both the dual pressure regulating unit and the exit valve are connected to the dual entry valve unit in different positions and the exit valve is connected to the dual ent valve unit along a rotational axis wherein the exit valve and the dual ent valve unit both rotate about the rotational axis.
