Where do you draw the line when they're this bad?

They followed the instructions, just not all the way through. They must have needed them for a kneeling pad. They made it to the first fitting and made sure both boilers were the same. "Connect riser to boiler with 2-1/2" elbow and nipple (not shown)". That part is to the letter on both boilers.

Now onto the puzzle. In calculating the venting, I figured the short main (16' of 2" feeding 2 rads) would need 2 Gorton 1's. The long main came out to 1.8cuft. so I used a B&J Big Mouth on that one. On a start up with timing starting when the 4" riser is steam hot, it took 6min for steam to close the Gorton side. After 6min 30sec. The Big Mouth stopped venting. When you take the vent off, still nothing. The boiler continued to fire for the next 12min. At 18min., the B&J vent started venting again. 2min. after that, steam arrived along with the sound of the water draining and some minor water hammer until the vent closed. Roughly 25' of the piping in inside an oak soffit. When I look through from either end, I don't see where the dry return could have any kind of a sag that would allow enough water to collect and block the system from venting. On a start up cycle the auto feeder cycles 2 times on the warm up. On long off cycles the water level in the sight glass is about an inch from the top. Would it be worth while to check the fittings at the end of the main where it drops to the dry return to see if there is something restricting the flow and allowing water to stack. Or can I assume the whole problem stems from the improper near boiler piping? BTW I did put in a skim port and skimmed the boiler. I also removed the bottom plug and wand washed the boiler.

    For what it's worth, I would never try to sell improvements to such a system without fixing the NBP. You don't want to end up like a dog chasing it's tail. Years back,when encountering such situations, I tried to do customers a favor and play with the main venting....It never worked out in the customer did not end up saving any money. The system will never ever work properly with the current piping. Tell the customer that they first need to have the piping changed and then you can move on from there if necessary. If they don't agree then you should just walk and leave the trouble to somebody else

    But don't you know that if you turn the header so its vertical you don't need an equalizer?........


    :s

    I mean, come on, at least they used both supply tappings.....

    I'm laughing to myself as I read your post and view the photos.

    Around here, almost every 'modern' installer installs a single 2" riser (copper or steel, depends on copper futures market I guess) from the boiler to the old header. Could be 250, 350 or 450 square feet EDR, doesn't matter. Most often there are two 2" steam mains in the "standard" steam house around here. Not sure what book they are reading, but I doubt the Dead Men ran two 2" single pipe mains because they felt like it. I also doubt the Dead Men would ever consider using a single 2" riser from the boiler to the typical 3" header. I try to educate the customer by using this analogy; would you prefer the firemen uses a garden hose or a fire hose to extinguish a big fire at your house? Most seem to get it and appreciate the improvement in performance when we're done.

    It's not all bad, they took the trouble to install the skim port!

    I would save the iron cap and put a sawzall to the rest of it.

    I think I've seen every one of those errors before, but just not all on one boiler, let alone on two boilers sitting side by side. WoW..... Just WOW.

    There once was a time when Dunkirk actually insisted you use threaded iron or steel pipe only but that was many years ago.

    Funny how even as novice only knowing what I picked up here I can see a lot of errors.

    Everything lower then the (what is that 4") main gets replaced!
  • Double DDouble D Posts: 224Member
    Correct, 4" reduced to 2" copper with a 4" X 2" bushing.

    As someone mentioned above, that Home owner did save a lot of money on install. Looks like poor bastards that did the job didn’t own a G300 machine and learned soldering from YouTube. MASSIVE LOL here. Looks like home owner is about to pay for another proper install. IMHO, need a sawzall and a new NBP after that.

    I hope they sized the boilers to the system and not to their inner voice callings ;)

    I cringe when I see steam boilers NBP done in copper
