Bertelli & Partners Ignition Unit Immergas Victrix Zeus Superior Ref. 025360
Ignition unit Bertelli & Partners, model TYPE AM, for Immergas boilers from the Victrix Zeus Superior and Hercules Condensing range. It is not a simple transformer: it is a PCB with connectors for flame sensor, spark electrode, reset, and lockout. It operates at 230V~ 50Hz. It is replaced when the boiler does not ignite, locks out after attempting to ignite, or shows a flame sensor fault.

How to check if ref. 025360 is the part for your boiler
What determines it is not the boiler model, but the reference printed on the part you already have installed.
- Find the reference printed on the installed part and check whether it matches the catalogue reference 025360. If it is not visible, do not identify the part from its shape alone.
- Check the full boiler model on its data plate and look for it in the model associations on this page.
- Compare the connections and physical body with the original part before installation.
- If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Symptoms and faults that the ignition transformer 025360 resolves.
The ignition transformer generates the high voltage for the spark of the electrodes. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler tries to ignite several times, you can hear clicks, but the burner does not light.
Cause: The ignition unit does not produce the necessary spark, although it continues to send the ignition command.
Check that the ignition electrode is not dirty with soot and that the spark gap is correct before considering that the control board is faulty.
- 02
The boiler ignites for a moment and then locks out with a flame detection fault.
Cause: The circuit that detects the flame in the unit does not recognize the signal, although the burner does ignite.
Check that the cable and the flame detection electrode are properly connected and free of rust before replacing the control board.
- 03
The boiler locks out and needs to be reset manually every time an attempt is made to turn it on.
Cause: The lock/reset function in the control unit cuts off the gas supply after several failed ignition attempts.
Note how many attempts it makes before locking: if it locks on the first attempt without clicks, suspect the power supply wiring of the control unit.
- 04
There is no spark visible or audible at the electrode when starting the boiler.
Cause: The boiler is not sending the ignition current to the electrode, so there is no spark to initiate combustion.
With the boiler turned off and without power, visually check that the high voltage cable to the electrode is not broken or disconnected.
Fault codes from Immergas that this part resolves.
| Code | Fault | Diagnosis and solution |
|---|---|---|
| E01 | Ignition fault | The boiler cannot ignite. This may be due to a problem with the gas supply or a fault in the ignition system. If the transformer is not receiving power or is defective, the spark will not be generated. Check the condition of the transformer and ensure that it is functioning properly. |
These symptoms can have more than one cause. If your boiler displays a fault code, send it to us via WhatsApp along with a photo of the labeling, and we'll tell you if this is the part.
