Weil mclain boiler section replacement
Are there any work instructions out there for replacement of an intermediate section in a well McClain CG hot water boiler? I replaced a cracked intermediate section in my boiler and all was happy and dry for 2 years. Then the joints started leaking. I used all new square cut o rings and the right high temp silicone on the flanges between all the sections and on the o rings. it only held for 2 years so I must have done something wrong. Tie rod torque Wrong perhaps? Silicone on O rings or not?. Any advice?
