Welcome! Here are the website rules, as well as some tips for using this forum.
I have a customer with a Buderus 215 the is leaking exhaust from between the sections. The boiler is 12-14 years old. I have never had to deal with this kind of problem. My question is how to go about fixing it. Do I have to take the sections apart or is there a sealant to inject without taking it apart. I have attached pics of my temp fix.
