De Dietrich 97553152 ignition transformer RV 1174 03

The ignition transformer steps mains voltage up to the level that produces a spark at the ignition electrode gap. It is energised only during the ignition period of the burner sequence, under command from the burner control. Parts of this type are selected by their secondary voltage and current, primary voltage (230 V is typical, though 110 V and 24 V variants exist for different control schemes), duty cycle, mounting pattern, terminal arrangement, and the connector profile of the high-voltage cable. The secondary cable is silicone‑insulated to withstand both high voltage and the heat near the combustion head. A hardened or cracked cable will leak the spark to earth, producing a symptom that mimics a failed transformer; checking the cable is therefore a standard diagnostic step when spark is weak or absent. This catalogue entry covers the De Dietrich 97553152 ignition transformer, also listed under manufacturer code 336.634.001 and catalogue article 336.634.001. The part belongs to the ignition transformers category. No further specific data about this article is available in the source information; the above generic description applies to ignition transformers of this class. When replacing a transformer of this type, always confirm that the primary voltage matches the burner control output, and that the secondary high‑voltage rating is compatible with the electrode gap and the burner manufacturer’s specification. The physical mounting and the high‑voltage connector must also match the existing installation.
