Saunier Duval ThemaClassic F24E Burner Ref. S1004200
The gas burner mixes air and gas and holds the flame that heats the heat exchanger in the Saunier Duval ThemaClassic F24E boiler. When it malfunctions, you may notice difficult ignitions, irregular flame, strange noises, or lockouts due to flame failure. It is compatible with other models in the Thema range, such as the F 25 E, and in the Themaclassic range, such as the C 24 E and C 25 E, among others. It should be replaced when these symptoms are detected or if the boiler's performance is affected.

How to check if the part S1004200 is the one 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 S1004200. 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 burner S1004200 resolves
The burner performs the combustion of gas. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler shows a flame error and locks out as soon as it tries to start.
Cause: The ceramic elements of the panel do not heat evenly and the ionization signal is unstable.
Check the connectors of the burner wiring, tightening them or cleaning the rust, before declaring the part faulty.
- 02
There is some ceramic element of the panel cracked or broken.
Cause: Repeated cycles of heat and cold eventually cause the ceramic to crack over years of use.
Inspect the boiler while it is stopped and cold, checking the entire panel for cracks or irregularly darkened areas.
- 03
The flame burns well in one area of the flat panel and poorly or not at all in another.
Cause: That section of the ceramic panel is obstructed or damaged, and the air-gas mixture is no longer uniform there.
Turn on the boiler and check if the flame covers the entire width of the panel, not just one side, before replacing it.
- 04
The wiring of the burner appears burnt, discolored, or with loose connections.
Cause: A poor connection in the wiring prevents ignition or flame detection even if the ceramic panel is in good condition.
visually inspect the wiring and, if you suspect internal breakage, check its continuity before purchasing the complete panel.
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.
