In certain embodiments, an apparatus includes a burner. The apparatus can also include an intake valve that includes an input for receiving fuel from either a first fuel source at a first pressure or a second fuel source at a second pressure. The intake valve can include a first output for directing fuel received from the first fuel source and a second output for directing fuel received from the second fuel source. The intake valve can include an actuator configured to permit fluid communication between the input and the first output or between the input and the second output. The apparatus can include a pressure regulator that can include a first inlet for receiving fuel from the first output of the intake valve and a second inlet for receiving fuel from the second output of the intake valve. The regulator can also include an outlet for directing fuel from the pressure regulator toward the burner.
