Equalizer

Why didn't you just pipe the equalizer on the other side of the boiler? or use the other riser coming out of the boiler to make the piping a little cleaner?

Nothing wrong with the 45 in the equalizer as long as the pipe size meets the min. mfg. requirement. I'm more concerned about the 1st main takeoff from the header. It shouldn't be horizontal. Either 45 from or fully vertical.

@Captain Who i think that's a coupling. you can see the horizontal line in the fitting. I was thinking the same until i saw the line.

I don’t see anything that would void the warranty. What are you referring to?

Is that a Tee at the Yellow arrow ? If not where does the pipe at the Orange arrow go ?

I am also not a fan of the bushings. But not such a big deal. That rule about reducing one pipe size is really counterintuitive and I don't agree. And neither do any of the boiler manufacturers. The larger the header, the less condensate you'll have, because velocity is reduced. So if anything, the bigger headers, should get smaller equalizers. But in reality, the only driving factor is really the boiler size.

The issue with bushings, is that in theory , and in practice, they can create a water dam. Reducing elbow, would give you better flow. But not a big deal, in strait vertical application.

The larger the header, the less condensate you'll have, because velocity is reduced.

I don’t follow this at all but regardless the size minimum on the EQ has nothing to do with condensate—we’re talking teaspoons.

It’s about carryover

I have the same question?

Here is the illustration from the manual on the left and I have made your piping arrangement on the right. I do not believe that your main rizer on the right side should be connected the way you did it. Red piping is not a good design.

This might be a better design

@ChrisJ But that could get him in trouble with Weil McLain regarding warranty because the manual specifies that "Steam supply must be on the same end as controls"

@jmerrill Make sure your equalizer is 1-1/2" min. because that is what is specified in the manual.

@jmerrill could always go overboard like Paul did and use a double riser from the boiler into a drop header the there sill be plenty of room to put the two main risers into the header. Wouldn't that look nice?

It is a Tee

here is what I see behind that 3" header coming off of the riser.

What I see coming off of the 3" riser is from left to right: Yellow arrow is pointing to a 3" TEE < 3" pipe nipple < 3" coupling < 3" pipe nipple < 3" 90° elbow ^ 3" riser out of the boiler. The Tee in the header puts the steam in two directions ← → to get to to the different main risers. Not a good design!

Here is the same photo with the hidden pipe covered by the header:

My experience, is that residential steam boiler warranties are absolutely worthless. Have yet to see one be honored.

Why scare the OP off? 100 people look at this and you get 100 ways to pipe it. Its done. Is it textbook? No will it work? Yes.

@jmerrill If you pitch the header downward towards the equalizer at 1" per 10 ft., then the section to the right of the Tee that feeds the main on the right will work as a counterflow header and the condensate will flow back wards towards the equalizer.

Mucking the guy's thread up but try making this work without pitch

Steam and Condensate don't give a rat's a whether they are in a pipe that humans call a header or a main. The diagram from peerless depicts the concept of proper pitch needed when steam and condensate flow in opposite directions, as will be the case in that stub extension of the OPs header (if he pitches it correctly), to the right of the Tee. Don't know how to explain it any more than that, except to say that anything he can do to keep condensate from being blown up into that main on the right will be a benefit. Basics matter most when things go wrong……

PS (lol): Peerless says in the diagram "maximum header length 100 ft."

Refuting the basics of steam piping knowledge passed down by the Dead Men certainly is…….
