Well the heater says 12.5in wc inlet and 11 in wc manifold. I was checking the manifold and could never run 11” there it would trip the high limit every little bit. I think I had the inlet pressure down to the 8 ish range to keep it going... but what is interesting is I moved that heater to a different location and a different regulator and it worked ok for a whole day until last night a midnight I was swapping heaters around cause it was tripping high limit again on a Different regulator. I’ve had two that seem to have this problem and I’ve talked to techs about and they think my gas pressure is to high... but not according to my mannometer which is bran new..
