ABSTRACT:
A fuel control system having a temperature responsive control device for thermostatically controlling the flow of fuel from a source thereof to a burner and having an adjustable by-pass means by-passing the temperature responsive valve of the device for providing a by-pass flow of fuel from the source to the burner to sustain combustion at the burner, the by-pass means comprising a tubular member provided with an inlet and an outlet for respectively being interconnected to the source and to the burner. The tubular member has a passage therein interconnecting the inlet to the outlet and carries an adjusting member for adjusting the rate of flow of fuel through the passage between the inlet and the outlet of the tubular member and, thus, the amount of fuel being by-passed to the burner. The tubular member has means for interconnecting the source to a pilot burner independent of the passage thereof.
