New steamer in a church

MaxMercy

I was doing some non-heating related work at a church and the caretaker showed me their new install, about 90 percent completed. To be commissioned at the end of the month. I don't know enough about steam to even be dangerous, but this looks like a pretty good install to me, although I wonder if the header should be higher? If this pic loads, I'll add more. Thoughts?

I don't like the welded pipe, but as long as the header is 24" above the waterline and the pipes are sized correctly, it should meet W-M's specs.

Is this gravity or pumped return?

Here is what I see. The horizontal part of the riser from the boiler to the header may be too short since the header is on the wrong side of the boiler, see illustration. The offset is past the side of the boiler, just the wrong side of the boiler. Not sure if that boiler model is 788 through 1188.

This may not be a big deal, I do not know, the flange coupling may allow some extra flex. However with the Notice below, IMO the piping is not as shown. It is almost like a mirror image with shorter pipes so less flex.

I like this method better than the pigtails, lots of clean-outs and bigger pipe throughout.

Offsets are short. Some don't think welded pipe can move but if the offsets are long enough it will.

The long horizontal with the equalizer isn't ideal you should drop below the water line before any horizontal but its probably not an issue.

Guessing it is an 1188 5" risers 8" header and 4" equalizer

If you blow the picture up and look at the welds they are all snotted up.

Almost looks like they hired me to weld it.

Don't know where this is located but in MA. they wouldn't accept the firomatic switch mounted on the boiler, but come to think of it they are not required on gas here anyhow.

it isn't terrible but it is off enough that i'd ask if the boiler matches the connected radiation.

both safeties on the same tapping isn't great. if you're welding a header, easy enough to weld a bung on it for the manual reset pressuretrol.

not sure what is with that capped stubbed piece of pipe.

that riser that disappears through the ceiling might need a drip.

the mains should connect separately to the header after the boiler tappings, not be teed together and connected to the header at one point. if there is a lot of condensate coming down that riser it is likely to bang and have other issues in that header

I don't like the welded pipe because the welds look like they were done by a blind person. I mean if one is going to weld, one should know what they are doing. Is this typical of the "quality" of welds in this industry?
