How do I stop my pilot being extinguished when the main burner ignites?

Baxi 701 RS

The pilot lights fine and the thermocouple glows nice and red hot. At times, when the main burner ignites it is possible to see the pilot flame being blown to one side and the thermocouple cools down causing annoying shut down.

The gas valve and thermoucouple have recently been replaced.

You will probably find the boiler has a vitiation sensing device and the pilot is going out due to lack of oxygen. The only advice anyone should offer is to get a gas safe registered engineer to check the boiler. It is illegal for anyone who is not gas safe registered to work on gas appliances.

has whoever replaced the gas valve checked the burner pressure on main flame is correct and the pilot flame is correctly set? the pilot injector may be blocked, it needs a couple of hours tlc by a good engineer

Ensure the pilot is clean should have a sharp flame and clean heat exchanger check flue air inlet box is not blocked corroded and assembled correctly
