Anstoss Ignition transformer 07000079/04

The Anstoss ignition transformer 07000079/04 is designed for ignition and stable operation of gas and oil burners in heating equipment. It generates a high-voltage pulse to ignite the fuel mixture, ensuring start-up of the ignition system. The device operates with a supply voltage of 220–240 V and a frequency of 50–60 Hz, consuming 10 W of power. It is rated for ambient temperatures up to 85 °C and has a temperature class of -5/+185°F. Its compact design facilitates convenient installation in ignition systems.

Parts of this type are selected primarily by secondary voltage and current, primary voltage (commonly 230 V, but 110 V and 24 V versions exist), duty cycle, mounting arrangement, terminal type, and connector pattern for the high-voltage cable. Before ordering, verify the primary voltage from the product label or technical data sheet, and confirm that the mounting footprint and cable connector pattern match the original. The transformer must be securely grounded, and the high-voltage output must be routed with adequate clearance from the burner case to avoid flashover.

Items of this kind typically fail due to hardened or cracked ignition cables, which leak the spark to ground and can be mistaken for a failed transformer. Other failure modes include internal short circuits or open windings, leading to no spark at the ignition electrode. When such a failure occurs, the burner may fail to ignite or may shut down during operation. Check the secondary cable and electrode connections regularly, and inspect the transformer for signs of overheating or physical damage.
