Don't hold back Jim , tell us how you really feel?[:-slaphap Thanks Jim for your comments. I think you have made some assumptions about how the heater was inspected or what techniques were used. The burner photo could have been submitted in a digital photo but it would not have illustrated it as clearly as the IR. Nevertheless, I don't see how the IR "clouds" anything, in fact, I thinks it paints the picture quite clearly. Ok, maybe it was a silly question to ask and I shouldn't have questioned my judgement. I had just gotten the call back from the angry seller that there is nothing wrong with the heater. I just wanted to make sure that I wasn't missing something.
