Chaffoteaux Niagara Delta 30 FF Gas Valve Ref. 61303305
If your boiler does not ignite or you experience flame lockouts, you may need the gas valve Chaffoteaux Niagara Delta 30 FF. This valve regulates the gas to the burner according to the instructions on the boiler's PCB. When it fails, you may see fault codes such as 5 01, which indicates a lack of flame, or 5 02, which signals that the flame is present with the valve closed. It is compatible with several models in the Chaffoteaux Niagara Delta range, including the Niagara Delta 30 FF and the 24 FF, among others. It should be replaced when it shows signs of malfunction or error.

How to check if the ref. 61303305 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 61303305. 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 gas valve 61303305 resolves.
The gas valve regulates and modulates the gas flow to the burner. These are the typical symptoms and what to do:
Common symptoms and faults
- 01
The boiler does not ignite, there is no smell of gas, and the burner has no flame.
Cause: The gas valve does not open because the internal mechanism does not receive the command from the control board.
Check that the main shut-off valve is open and that there is power reaching the gas valve with a multimeter.
- 02
The display shows a lock due to a ignition fault as soon as it starts.
Cause: If the valve does not open in time, the electrode does not detect a flame and the control board shuts down the cycle for safety.
Check the wiring and connector of the gas valve before replacing it; a loose connection can cause the same fault.
- 03
There is a smell of gas near the boiler even though the burner is off.
Cause: A worn seat or shutter in the gas valve allows gas to escape even when the mechanism is closed.
Close the gas valve and call a technician if you detect a smell; do not continue trying to ignite it.
- 04
The boiler ignites, but the flame is weak or unstable.
Cause: An improperly adjusted internal pressure regulator does not provide the correct gas flow to the burner.
Observe the color and stability of the flame for a few seconds before deciding if it is the gas valve.
Fault codes Chaffoteaux that this part resolves
| Code | Fault | Diagnosis and solution |
|---|---|---|
| 5 01 | Flame absence. | The gas valve/block does not open or delivers insufficient flow during ignition, so no ionisation current is generated. Check voltage on coils during start-up attempt and dynamic pressure with a manometer on the manifold; check continuity/ohmage of the coils. |
| 5 02 | Flame detected with gas valve closed. | The gas valve does not close completely (internal leak/eroded seat) and allows gas to pass even without a setpoint, causing flame detection 'with valve closed'. Check downstream tightness with the valve de-energized (pressure/leak test) and verify control board/wiring to the valve. |
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.
