Anstoss Ignition transformer VZ 2/25 HDC (L1080) 07000459

The Anstoss VZ 2/25 HDC (L1080) ignition transformer, SKU 07000459, generates a high-voltage pulse for igniting fuel in gas and oil burners. It operates at 220–240 V and 50–60 Hz, consuming 4 W. The transformer is designed for use with an ignition electrode and burner control, and features a silicone-insulated ignition cable with a maximum length of L1080. It weighs 0.15 kg and can operate in ambient temperatures up to 100 °C. This model is identified by manufacturer part number 07000459/04.

When selecting a replacement ignition transformer of this type, verify the primary voltage (typically 230 V, but 110 V and 24 V variants exist), secondary voltage and current, duty cycle, mounting arrangement, terminal type, and the high-voltage cable connector pattern. The ignition cable must be silicone-insulated to withstand high voltage and heat. Before ordering, compare these specifications with the original unit and ensure the cable length and connector match.

Common failure modes for ignition transformers include internal short circuits, open windings, or insulation breakdown, leading to weak or no spark. Symptoms on the equipment include intermittent ignition failure, burner lockout, or no flame establishment. Check the ignition cable for hardening or cracks, as these can leak spark to earth and mimic a faulty transformer. Also inspect the electrode gap and condition, as these directly affect spark reliability.
