I ended up buying a new regulator the was calibrated to 15" wc. Plus we checked with manometer. Propex themselves says it should run fine at 11-12 wc regardless of what is stamped on thier heater. Which is wierd. Anyway still getting code. It has to be internal. Thank you.
I hope you get it squared away, sounds like Propex might need to step up. I also hope they don't sully their good reputation as a result of feet dragging. I for one will be watching how this unfolds. Exactly as you pointed out, mine runs fine at 11"WC right on the button so it sure seems that something else is going on.
