De Dietrich S101619 ignition transformer with ignition electrode

This is an ignition transformer that includes the ignition electrode as a single assembly, identified by the catalogue article 336.946.065 and manufacturer code S101619. Parts of this type combine the high-voltage generation and the spark delivery in one unit, simplifying replacement on burners where the transformer and electrode are mounted together. The transformer produces the ignition spark when commanded by the burner control; the electrode’s tip sits in the flame zone and must be clean and correctly gapped to ensure reliable ignition. The assembly includes the electrode, so the gap, ceramic insulator condition, and mounting flange are all part of the single replaceable item. When selecting a replacement, the electrode length, bend, and insulator diameter must match the burner head geometry, and the transformer’s electrical ratings—secondary voltage, output power, and duty cycle—must be compatible with the burner control and the ignition circuit. Typical failure modes for such assemblies include carbon tracking on the transformer casing, cracked ceramic on the electrode, tip erosion, and a widened gap that delays or prevents sparking. Because the electrode is not separate, the entire unit is replaced rather than the electrode alone. Always verify the physical mounting pattern and the connector type before fitting. This item is branded De Dietrich and is listed under ionization and ignition electrodes in the catalogue.
