Elektroda De Dietrich 97956330

This De Dietrich 97956330 electrode is a spare part listed in the Ionization & ignition electrodes category. Electrodes of this type serve one of two functions in a gas or oil burner: an ignition electrode delivers a high-voltage spark to light the fuel-air mixture, while an ionisation electrode proves the flame by passing a small rectified current through it. Some burner designs combine both functions in a single electrode. Both types reside in the flame zone and are subject to wear. When selecting a replacement electrode, the key parameters are the electrode length and bend, the diameter and condition of the ceramic insulator, the spark gap (where applicable), and the mounting flange dimensions. The shape is matched to the burner series and the position of the electrode relative to the burner head or pilot burner. In systems with a pilot burner, the electrode is usually positioned to ignite the pilot flame, which then lights the main burner and provides a continuous flame signal. Typical failure modes include an eroded or bent tip that lengthens the spark gap and delays ignition, cracked or sooted ceramic that causes short-circuiting to ground, and deposits that degrade the ionisation signal. This De Dietrich part is identified by manufacturer codes 97956330 and 336.946.037.
