De Dietrich Ionisation probe 97580451

This flame-sensing electrode from De Dietrich (SKU 97580451) uses ionisation rectification to detect flame presence. It features ceramic insulation and is designed for mounting in the flame zone as a consumable component. The electrode is intended for use in De Dietrich DTG 1200V ECONOX, DTG 1200V ECONOX Diematic, and DTG 111 NEZ boilers. It fits into the burner and provides a rectified current signal to the burner control.

Ionisation probes of this type are selected by physical dimensions such as probe length, bend angle, insulator diameter, the gap between the electrode tip and the burner earth, and the mounting flange pattern. The probe must match the burner head or pilot burner geometry. Before ordering, compare these parameters with the original part or the manufacturer's specification. During installation, verify the gap setting and earthing, and inspect the ceramic insulation for cracks and carbon deposits.

Typical failures include tip erosion, cracked or sooted ceramic insulation, and a drifting spark gap that lengthens ignition time. When the ionisation current is absent or too weak, the burner control locks out, preventing burner operation. Check the ceramic for hairline cracks, clean carbon deposits, and ensure the gap and earthing are correct.
