More Information
Summary:According to one implementation a dual-fuel wall heater is provided that comprises a gas burner suitable for receiving a first gas or a second gas, a first pilot burner adapted to the first gas and a second pilot burner adapted to the second gas. The heater includes at least one pressure regulator, a control valve in fluid communication with the pressure regulator, and a selector valve in fluid communication with a gas outlet of the control valve. Each of the first and second pilot burners is arranged to direct a flame toward respective first and second thermocouples. The control valve includes an electromagnetic valve electrically connected to both the first and second thermocouples, the first and second thermocouples being arranged electrically connected in reverse polarity, such that in the event of the second gas being improperly supplied to the first pilot burner the resulting electromotive force generated by the first and second thermocouples is less than a disengagement threshold value of the electromagnetic valve.
