SEveral people have suggest the minimum burner pressure . This needs to be checked before you spend 90 quid on a board.
I don't have any problem in calling someone, but I would like to first be reasonably sure that I need someone. The min burner pressure has indeed been pointed out by several people, however this is still inconsistent with the fact that I am no seeing any flame failure light.
If you can enlighten me as to the reasons why min burner pressure is wrong and I do not get a flame failure light, I will be more than willing to call someone in, as there will be a reasonable level of confidence that the issue can be due to that.
