SIT 504 NAC Spark Train - Fagor FEB24E - Ref. N55G008M4

Ignition group (spark train) manufactured by SIT, model SIT 504 NAC, for Fagor boilers FEB20E, FEB24E, FEB24ED, and FEB24ED3. It generates the spark that ignites the gas burner. It operates at 230V and 50/60Hz. The replacement requires first confirming the fault of the part through technical diagnosis, even when the boiler does not ignite, shows a flame or ignition failure error, or makes several ignition attempts without starting.

Guide

How to check if it is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

  1. Find the reference printed on the installed part and check whether it matches the catalogue reference —. If it is not visible, do not identify the part by its shape alone.
  2. Check the full boiler model on its data plate and look for it in the model associations on this page.
  3. Compare the connections and physical body with the original part before installation.
  4. If anything is unclear, send us a photo of the marking via WhatsApp before placing your order.
Diagnosis and fault codes

Symptoms that require diagnosis in the burner

The burner performs the combustion of gas. These are the typical symptoms and what to do:

Common symptoms and faults

  • 01

    The boiler tries to ignite several times, there are clicks, but it does not start.

    Cause: The spark train does not produce a strong or consistent enough arc to ignite the gas.

    Listen for a clear spark sound when trying to ignite; if the clicking is weak or intermittent, suspect the spark train.

  • 02

    The boiler shows a fault of flame failure or ignition when trying to start.

    Cause: Without spark or with weak spark, the gas does not ignite and the flame detector does not receive a signal.

    Check that the electrode is clean, free of rust and deposits, before replacing the entire assembly.

  • 03

    There is no clicking or spark when the boiler tries to start.

    Cause: The spark generator has stopped producing an arc, usually due to electrode wear or an internal fault in the ignition transformer.

    Check the electrical connection of the spark train and ensure that the high voltage cable is properly fitted before replacing it.

  • 04

    The boiler locks out after several failed ignition attempts.

    Cause: The control unit counts the attempts without detecting a flame and locks for safety when the spark train does not ignite the gas.

    Check the distance and position of the electrode relative to the burner before declaring the spark train faulty.

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.
