I have just had a new gas valve fitted,plus a new thermocoupling. Went through lighting procedure and gas goes to pilot,but pilot will not stay alight.
please help
Is the pilot flame warming the t/couple correctly as i dont think this boiler has any overheat device fitted.It has to be one of the two parts you have changed.Make sure you have used the correct thermocouple and that the nut on the gasvalve end is not slack.
