Ok, just got a new regulator and installed it.
Seems like problems are persisting. One tank will not run heat, regulator still goes red. Other tank will run heat and burner on the stove at the same time. If i try to run more than 1/2 burners while heat is on it will kick the heat off and just the fan will run. odd eh ?
Yep starting to think i should have gotten new pigtails now.
We have always camped in the south/east US. in the summer, feeling silly being Canadian and just discovering my heating system now. Ha!
