The manufacturer code is given as S103251 and 336.823.005, and the brand is De Dietrich. No further technical specifications for this specific article are available from the data provided. An ignition transformer of this type steps up the mains voltage to a high level that produces a spark at the ignition electrode gap. The transformer is energised only during the ignition period, under command from the burner control. When replacing such a transformer, selection depends on several parameters: the required secondary voltage and current, the primary voltage (230 V is common, but 110 V and 24 V versions exist), duty cycle, mounting arrangement, terminal type, and the connector pattern for the ignition cable. The high-voltage ignition cables must be silicone-insulated to withstand heat and voltage; a hardened or cracked cable can leak the spark to earth and give a false impression of a faulty transformer. The transformer works in the ignition sequence controlled by the burner control. After pre-purge, the control energises the transformer, which creates a spark at the electrode just before fuel opens. The spark must ignite the fuel within the safety time. When sourcing a replacement, verify the primary voltage and the physical fit of the mounting and terminals. Use only matched ignition cables suitable for the voltage and temperature.
