What it is

The Johnson & Starley ignition electrode (part 1000-0709655) is a spark electrode that lights the burner in Reno series boilers. It is supplied with a gasket and two screws for refitting.

Signs this part needs replacing

  • Boiler fails to light or locks out during the ignition sequence
  • No spark at the electrode when the boiler calls for heat
  • Repeated lockouts that clear after a reset
  • Cracking, sooting or erosion visible on the electrode tip
  • Damaged ceramic insulator or tracking marks

Before you order

  • Check the boiler model against the fit list above
  • Confirm the electrode pattern matches the one removed
  • Inspect the gasket seating face for damage before refitting
  • Isolate the gas supply and use a competent person for the work
