What it is
The Electrode SIT is a pilot ignition electrode manufactured by Johnson & Starley, supplied under part number BOS01970. It is used on non-ASD pilot assemblies to provide the ignition spark at the pilot burner. It is listed as a gas boiler and warm air unit spare within the electrodes category.
Signs this part needs replacing
- The pilot fails to light, with no spark at the pilot burner.
- Sparking is weak, intermittent or absent when the ignition sequence runs.
- The electrode tip is eroded, cracked, or has a heavy carbon build-up.
- The pilot lights but will not hold, or extinguishes shortly after ignition.
- Visible damage or deterioration to the electrode body or its insulation.
Before you order
- Confirm your appliance model against the manufacturer's parts list.
- Check that your pilot assembly is the non-ASD type, as this electrode is specified for non-ASD pilots.
- Inspect the existing electrode and its lead for damage, sooting or poor contact before replacing.
- Have the appliance model and GC number to hand when checking compatibility.
