The flames are blue with very little if any yellowing. It stopped working properly again most of the day. Reset it several times now it's running normally again. Another thing is if it was tripping the rollout switches I should have to reset them as they are the mechanical type, but I don't, it will start up and run normally after several resets. I think you're right I will have someone to come and take a look, I'm out of ideas, thanks for the suggestions. I'll post what they find.
