THanks in advance.... I have a natural gas Gilbarco boiler in my 50 year old cape (it was an oil to gas conversion). 2 floors, one zone. My question is , I have has this system for 7 years and all of a sudden the pressuretrol is starting to cut out before the radiators even heat up. Pressure is building without heat, so the pressuretrol is doing its job (I think) but I cant understand what changed. I still dont have a complete understanding of the system as I have not had to do much to it in 7 years. I yield to the boiler masters... please help.
