I have changed the title of this from "Install Day 1" and updated this discussion to include the finished installed photos further down.
Hi Everyone.
I have had a few different discussions going on here lately and so many have offered their wisdoms to help me learn. Thanks to @EBEBRATT-Ed @ethicalpaul @Youngplumber @Jamie Hall @clammy @AdmiralYoda @kenlmad @GW @JUGHNE and others.

My installer showed up 1st thing this morning and went right to work building the new Burnham MST288 - so I thought I would share a few pics of Day 1 progress. Will post the final install tomorrow.

    There used to be a thing in the ASME code about the gauge glass tappings going straight into the gauge glass with no elbows, tees, or crosses etc

    A 2" header for three system takeoffs? Are we sure this is ok?

    Interestingly I started a discussion about the header a couple days ago... though didn't mention there were 3 take-offs...
    Similar to the advantage of 2 risers over 1 thus cutting the velocity out of the boiler in half, wouldn't the 3 vertical 2" takeoffs from the header serve to slow the velocity coming out of the header, before it enter the horizontal mains??

    Here's the link to the thread, and check out the video in it posted by @ethicalpaul

    That looks like @New England SteamWorks work if I ever saw it. Don’t think there is any question he did the velocity math @JohnNY. I believe that’s the MST288, in which case 2” is sufficient.

    Sounds good. FWIW I haven't read anything about this installation. To me, three 2" takeoffs suggests a higher EDR load than a 2" header should be able to handle. All good. Carry on. I'm gonna eat my Chinese food.

    I'm sure it must be out of the ordinary for such a small boiler to have 3 main takeoffs and from what I remember of the main layout drawings that I saw, this is a pretty out of the ordinary situation :)

    The existing had a 90 T out the side of the riser above the header and there was bull T at the top with
    1 1/2" pipe to the left and to the right. Hence 3 risers on the new MST288.
    Total EDR of radiators is only 233 sq ft

    So, OverKill is the word of the day. Nothing wrong with that... Larger pipe = less velocity. Probably could have used 1-1/2" risers and valves but if the money is there, 2" won't hurt.

    BTW Nice looking job so far. Interesting that the boiler is getting piped and ready while the existing one is still in operation, Not always an option to make a quick switch on the same day of decommissioning the old and commissioning the new.

    Yours truly.

    How many take offs from the header doesn't matter a bit. It's a small boiler sized for the connected radiation. No matter how many take offs the load going out through the steam mains remains the same.

    Now, what does Every boiler mfg put in their instructions? "systems with unusual design or extensive piping" etc etc or words to that effect. Consult with the MFG. It may be a case of upping the pick up factor a snitch for extra supply piping

    BTW, I’ve got the perfect home for that five panel door I see in the background. I’ll try to swing by later.  :D:D:D

    @Clance - I’m in Virginia so a bit too far to drive up.  I am bummed out to miss the opportunity!!  Maybe someone in your area will read this thread and give them a good home.

    @Steamhead - heres a pic of what was there before. What wasn't there before is vents - not one on the system anywhere...

    The MegaSteam is a much better boiler than that V8 ever was. But, I'm curious as to why you went from an indirect tank to a tankless coil.....................

    @steamhead
    The Installer suggested it. Small apartment with single tenant. I've never had a coil so it's be interesting to hear how it performs for her. My boiler is going in on the 10th, also a Mega Steam MST 288 and I'm staying with my gas hot water.

    is there any point at all in the "equalizer" the way it was piped in the old system?

    The new MegaSteam is the 3rd boiler since the old converted coal boiler came out around 1980.  The equalizer, wet returns, and Hartford loop are original to the coal boiler... crazy that no one re-piped it before now.  That’s why I’m psyched to have somebody that knows a lot about steam come do the installs.  Everything painted  silver in the picture is original.

    ....taking notes for when I attempt my boiler re-pipe in the spring. And I sooooooo wish Burnham made the Megasteam gas fired or at least approved a gas conversion kit.

    I spent the day insulating - 1 1/2" on the steam and 1' on the returns. What ever you guys charge, it should be more :) It wasn't as fun as I though it would be.
    Here's a couple pics... need to wait to do the rest until the 2nd boiler gets installed.

    looks great, would you mind sharing where you got your insulation? Looks like good stuff.

    I ordered it online from buyinsulationproducts.com.  Reasonably priced, much cheaper than Grainger and they had everything in stock.  Ordered on a Sunday, Shipped from NJ on Monday, received it on Wednesday.  For fiberglass pipe insulation they have both Owens Corning and Johns Manville and they reserve the right to ship which ever they have on hand.  On my order, I noticed I received Johns Manville for bigger sizes and Owens on smaller sizes. Here’s a link to their site:
