Patent ID: 8752541

Claim:
A heating system for use with either a first fuel or a second fuel different from the first, the heating system comprising: a fuel selector valve comprising: a housing having an input, a first output, and a second output; a first valve in-between the input and the first output, the first valve comprising a first valve body and a first valve seat, the first valve configured to have a closed position wherein the first valve body is engaged with the first valve seat and an open position wherein the first valve body is disengaged from the first valve seat; a second valve in-between the input and the second output, the second valve comprising a second valve body, and a second valve seat, the second valve configured to have a first closed position wherein the second valve body is engaged with the second valve seat and an open position wherein the second valve body is disengaged from the second valve seat; wherein the fuel selector valve is configured such that the first valve and the second valve are configured to move between their respective open and closed position based on a predetermined fluid pressure acting on the valve and the pressure of the fluid entering the input of the fuel selector valve determines whether either the first valve or the second valve is open; a first fuel pressure regulator downstream from the fuel selector valve and in communication with the first output, the first fuel pressure regulator configured to control the flow of fluid within a first predetermined pressure range; and a second fuel pressure regulator downstream from the fuel selector valve and in communication with the second output, the second fuel pressure regulator configured to control the flow of fluid within a second predetermined pressure range, different from the first.
