Just wondering how you guys go about it. We are finding that in 7 - 10 yr old weil mclaing GV boilers, they are getting a fair amount of build up in heat x. Can only get to a portion of heat x through burner port and through flue breach. Get poor combustion if you don't take boiler apart and separate sections and brush and wash out, then reassemble w/ new gaskets and then she purrs along again. Tough job, all day. Any other solutions you guys have found?

    that boiler will only foul up if a bypass line is not installed.review the install guide before running it again.

    The GV is not a condensing boiler as you know.

    but the boiler is commonly field piped "in and out" on converted gravity systems, and systems with large water volume. As was previously mentioned, follow the piping diagrams. Weil has required pri-sec piping for more than 10 years on the GV.
