Sapco Electrode ZE-14-12-600 A1 BOI0072A35002

The Sapco Electrode ZE-14-12-600 A1 (SKU BOI0072A35002) is an ionization and ignition electrode used in burner and boiler systems. It is designed to deliver a spark for ignition and to monitor flame presence via ionization current. The electrode is resistant to high temperatures and soot, ensuring operation in harsh combustion environments. It is a component of the ignition and flame-proving circuits, suitable for gas, diesel, and combination burners.

When selecting a replacement electrode of this type, verify the physical configuration required by the burner: overall length, bend angle, insulator diameter, spark gap, and mounting flange type. The geometry is specific to the burner series, so confirm that the new part matches the original in mounting dimensions, electrode tip position, and insulator diameter. Set the spark gap to the manufacturer's specification for the burner, and ensure the ceramic insulator is clean and free of cracks. Check the connecting cable and ignition transformer for condition, as a weak spark or damaged insulation can cause intermittent ignition faults.

Common failure modes include erosion of the tip, cracks in the ceramic insulator, carbon sooting that bridges the gap, and a gradual drift in gap width. These issues can lengthen ignition time, cause a loss of flame signal, or lead to intermittent ignition faults. The equipment may fail to ignite, shut down unexpectedly, or produce a weak or erratic spark. Inspect the electrode for physical damage, clean or replace it if sooted, and verify the spark gap and insulation integrity.
