Abstract: A combined igniter and flame sense electrode for a dual stage gas burner that includes a first burner and a second burner is disclosed. The electrode includes a first conductive element mounted on the shaft and positioned closer to the first burner than to the second burner; a second conductive element mounted on the shaft and positioned closer to the second burner than to the first burner; and one or more electrical connectors connected to the conductive elements. An electrode according to the invention can also be used with a single stage gas burner, by placing the first conductive element at the position of high level flame from the burner and by placing the second conductive element at the position of low level flame from the burner. A gas burner assembly incorporating such an electrode, and a gas appliance incorporating such a gas burner assembly, are also disclosed.
