Claims20
A gas burner controller adapter, comprising:
- a first connection terminal configured to connect to an input/output terminal of a gas burner control device, wherein the input/output terminal is configured to receive a voltage signal of a flame ionization electrode;
- a second connection terminal configured to connect to an output terminal of the gas burner control device, wherein the output terminal is configured to provide a first electrical voltage signal;
- a third connection terminal configured to connect to another output terminal of the gas burner control device, wherein the another output terminal is configured to provide a second electrical voltage signal;
- a fourth connection terminal configured to connect to a single electrode configured to be used as an ignition electrode and as the flame ionization electrode;
- a DC/DC converter including input terminals;
- and
- an igniter having a transfer coil and an ignition coil,
- wherein the input terminals of the DC/DC converter are connected to the second connection terminal and to the third connection terminal and wherein a first output terminal of the DC/DC converter is connected to the transfer coil and a second output terminal of the DC/DC converter is connected to the transfer coil through a thyristor, and wherein a capacitor is connected between the first output terminal and the second output terminal of the DC/DC converter, and
- wherein the ignition coil of the igniter is connected to the fourth connection terminal and to the first connection terminal.
A gas burner controller adapter for converting a gas burner control device, which is configured to work in conjunction with a flame ionization electrode and a separate ignition electrode, to work with a single electrode that functions as both a flame ionization electrode and an ignition electrode, the gas burner controller adapter comprising a first connection terminal for connection to a single electrode that functions as both a flame ionization electrode and an ignition electrode;
- a second connection terminal for connection to a connection terminal of a gas burner control device;
- an ignition coil operatively coupled between the first connection terminal and the second connection terminal, the ignition coil providing an operative connection between the first connection terminal and the second connection terminal to pass along a flame ionization signal generated by the single electrode to the second connection terminal;
- and
- an ignitor control block operatively coupled to one or more connection terminals of the gas burner controller adapter that are for connection to connection terminals of the gas burner control device, wherein the ignitor control block is configured to selectively activate the ignition coil to generate a spark signal at the first connection terminal sufficient to cause an ignition spark at the single electrode.
A gas burner controller adapter for converting a gas burner control device, which includes flame ionization terminals for interfacing with a flame ionization electrode and ignition terminals for interfacing with an ignition electrode, to work with a single electrode that functions as both a flame ionization electrode and an ignition electrode, the gas burner controller adapter comprising
- a first connection terminal for connection to a single electrode that functions as both a flame ionization electrode and an ignition electrode;
- a plurality of second connection terminals for connection to the flame ionization terminals and the ignition terminals of the gas burner control device;
- a control block configured for selectively generating a spark signal at the first connection terminal sufficient to cause an ignition spark at the single electrode based at least in part on one or more signals received from the ignition terminals of the gas burner control device;
- and
- the control block further configured for providing a flame ionization signal generated by the single electrode to one or more of the flame ionization terminals of the gas burner control device.
