The Gas Valve Saunier Duval Opaliatherm TF 14 E regulates the flow of gas to the burner according to the instructions of the control board. When this part fails, the boiler does not ignite, there may be flame lockouts, or the gas modulation is not adequate. It is installed in boilers from the Opalia range, such as models C 14 E, C 14 G, and C 14 Y, among others. The need for replacement of this valve should be confirmed through diagnosis when the mentioned symptoms occur and the boiler does not operate correctly.

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.
- 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.
- 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 that require diagnosis in the gas valve
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: you can hear the spark igniter, but the flame does not catch.
Cause: If the gas valve does not open at the exact moment, the igniter sparks without gas reaching the burner.
Check that the gas shut-off valve is fully open and that no cut-off has occurred due to low pressure in the installation.
- 02
The flame is unstable, fluctuating on its own or appears yellow instead of blue.
Cause: The valve body regulates the gas flow to the burner, and a worn internal mechanism allows for an irregular flow.
Check if the flame changes when the demand for domestic hot water varies; if it always happens the same way, it points more to the gas valve than to another cause.
- 03
The boiler ignites well but it seems to have lost power and heats less than before.
Cause: The valve loses its ability to properly modulate the gas flow to the burner due to wear.
Ask the installer to check the incoming gas pressure before assuming that the fault is in the gas valve.
- 04
There is a slight smell of gas near the boiler, with no visible leak in the pipes.
Cause: A gasket or the internal body of the gas valve can lose tightness over the years.
Ventilate the area, turn off the main gas valve, and have a technician check it with a detector before you handle anything yourself.
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.
