in THE MAIN WALL
you have a nice bit of clear height above that boiler. A proper header and equalizer over good initial boiler risers will make for some very nice, dry steam. Skimp not and ye shall be well served. Don't blow it.

    correct install?

    Attached are pictures of a current install of a weil-Mclain eg 45 steam unit. Anything inherently wrong?

    steam piping

    just to follow up. It looks like the equalizer return is going to come from the ell on top of the tee going to the main. Is that right? Will condensate go up? Should I stop them now?

    They haven't got that far, but a hartford loop is planned. I am concerned about a lack of a header.

    Might be OK but get the manual and do it right.

    If that elbow at the top is going to head back down to an equalizer and the wet parts are piped correctly and you have a wet return somewhere that isn't in any of the pictures, then I think what you'll have could be functionally equivalent to the recommended piping.

    But why take a chance? Download the manual from weil-mclain.com and insist that they follow the diagram. It's not like it's more complicated than what you have now. On the bright side, at least they're using steel.

    They have since undone the suspect work which killed a half day and came up with another plan.

    Agreed. Install it properly.

    I did say they should follow the install guide. But why exactly wouldn't it work? If you look at what was done so far, the only thing really different would be where the main is connected, into the riser instead of into the short horizontal run back down to the equalizer. Does the steam know vertical from horizontal?

    The existing riser is plenty long. If I can assume that nearly all the condensate returns by a different path than back down the main--and I did ask if that was true--I think it might work OK. But, as I said, he still shouldn't do it that way.

    Of course, I could be very badly, stupidly wrong. If so, let me have it.

    The Why

    The reason it would not work as advertised is that the initial riser will draw up condensate with the steam. Sure the height works but half the height is spent with water falling back against an upflow of escaping steam.

    Steam knows vertical from horizontal when water is involved. Well, OK, the water knows and it is parasitic.

    The better approach as you know would be to turn horizontal to a header and roll that to the equalizer. The water goes back to the boiler much as a judo master rolls an assailant using his momentum. The dry steam is free to rise, leaving the fight behind.
