An ignition apparatus for a gaseous fuel burner having two areas of gaseous fuel discharge comprises a primary electrode positioned within a first area of gaseous fuel discharge and a secondary electrode having a first end positioned within the first area in close proximity to the primary electrode defining a jump gap, and a second end within a second area in proximity to the burner to form a ground spark gap. The burner has an outer and an inner periphery ignition area forming a torres shaped, or donut-like, burner separated by a gaseous fuel plenum through which the secondary electrode penetrates. The primary electrode may be mounted within the inner or outer periphery ignition area. A method of creating a dual point electric spark to ignite gaseous fuel at two separate areas within a dual port gas burner comprises grounding the burner, forming a series electric circuit which passes through the two separate ignition areas from a source of high voltage electric power to the burner, providing a jump gap within one of the separate ignition areas, and a ground spark gap in the other, and energizing the series electric circuit.
