ABSTRACT:
A tool for setting the width of a space between the tips of a pair of burner ignition electrodes so that an electrical spark will jump this gap, and the axial and radial distances of these tips forward of the center of a fuel nozzle outlet so that fuel discharged by the nozzle will be ignited smoothly and will not cause carbon deposits to build up on the tips. The nozzle is removably threaded in a threaded opening of a fuel supply pipe and is replaced by the tool during the setting operation. The tool has a threaded shank and a stop flange for supporting and positioning an annular groove of the tool so as to receive and set the ends of the electrode tips in the correct position. The groove is in an annular face formed by a shoulder of the tool and has an outer wall for holding the ends of radially extending electrode tips in the groove as the tool is rotated into a seated position in the fuel supply pipe opening.
