What it is

The BOS01449 is a combined electrode and lead supplied by Johnson & Starley. It forms part of the ignition and flame sensing circuit on Johnson & Starley Hispec, JAH and JT/RS warm air units and boilers. The electrode sits in the combustion path and the attached lead carries the signal back to the appliance control.

Signs this part needs replacing

  • The appliance fails to ignite or locks out repeatedly
  • No spark at the electrode when the ignition sequence runs
  • Flame sensing is intermittent, causing nuisance shutdowns
  • Visible cracking, erosion or heavy carbon build-up on the electrode tip
  • Damaged, brittle or heat-affected insulation on the lead

Before you order

  • Confirm the appliance model and GC number against the fitment list
  • Check the existing electrode and lead for physical damage before removal
  • Inspect the electrode gap and mounting position so the new part seats correctly
  • Isolate the electrical supply to the appliance before starting work
