    Looking good. Nice upgrade!
    Just so you know (I’m sure you already do), you could’ve mounted those pex manifolds upside down so you didn’t have to put in big loops to go into the bottoms.
    If I do a job in 30 minutes it's because I spent 30 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

    Looks great! glad to see the vent, dealing with power and recovery boilers most of the time it's the norm to always see them, most home or light commercial guys have no idea even what they do so many don't realize what kind of internal damage is caused from oxygen in the pipes,,,, great post!

    Your zone purge station is on your supply side, and your feed ties into the supply side also, how can you purge the zones

    Close the valve on the supply right off the boiler. The drain is open on the bottom.

    Close all the ball valves on the return. Close all the zone valves.

    Open 1 zone valve and open the ball valve on the return.

    Water will go up thru the zone valve, returns back down, goes thru the boiler, and out the drain valve which is below the shutoff on the top of the boiler

    Will actually be returning and removing the shutoff and installing a taco 3196 discharge bypass valve in its place
