Burnham Gas Boiler

810 Views 1 Reply 2 Participants Last post by  NiNe O
I have a Burnham gas fired burner that appears to have built pressure. It is leaking from under or inside the burner and the pressure value is full of moisture. I am thinking it is the expnasion tank. The relief value is not that old (nor is the expansion tank)....Where does this water leak from on the inside of burner and what do you think...? Thanks

Sounds like cracked heat exchanger or bad seal between cells if it has them.
