Weil McLain Boiler question

Has any one had any experience moving a 7 or 8 section WGO boiler.
I have taken Peerless boilers apart to get them on the job.
I was wondering how difficult it is to take apart a Weil McLain ?

    Shouldn't be that hard. However, you will need all new gaskets and roping -- it's not reusable -- and the odds are that you will need or at least want new tension rods and nuts.

    Done it a few times. No bullhead, or for other reasons. Very easy, just adds about hour or two on the job. You don't need new "O" rings, just mark the sections, and torque to specs

    Weil McClain has indicated to me that o-rings that have been installed and compressed should not be reused if the sections are taken apart.

    Tech-rep I called at W/M years back told me no need to replace the "O" rings as I was calling to get some. These boilers were fresh, never filled and fired, with pliable rubber. None have leaked as of yet, and that is going back about 10 years forward with Tankless also. Go figure. I find just as important is the rope gasket between the sections. Re-silicone is a must, and the target wall as well.

    Easiest boiler to take apart & reassemble imho.
    Inspect the O-rings real good first, before you try to reuse them. Any doubts, replace them.
