MST 396 Work In Progress

I got a late start on replacing the failed V-7 in my house this year due to a busy summer . I don't have any great pictures of the original boiler , just a heroic single 2 inch tapping that rose up 5 feet into an old header tight to the floor joists.
Poorly piped V-7's and drunk owners just don't last long together , both are on a highway to destruction with their foot to the floor. The V-7 out lasted me by 1 year , lol.
The wreckage of the past behind me ( along with the yahoo piped oil tank and the wet return with pipe just laying on the floor ) , here is where I'm at. I did not have the money or the time to seek out the Victorian antique cast iron fittings that I see on here , my header is constructed of rusty fittings that our plumbers had laying around. The last one has grey paint on it , it probably belongs to Washington Gas or something lol.
I have to connect the end of main drips tomorrow and get started on oil and water supply. The weather has been kind to me on this ( thank you Lord ) but I need to hustle. I'll scrounge some valves by next year , money and time ran out for those. Anyway , nothing fancy but I think I have a good start.

Great work!
That should produce nice dry steam and save you some money on the oil it uses.

Thanks guys , appreciate the comments.
I modified the pipe kit to suit the 2 1/2 fittings that I had. And I hope to save alot of money from the single tapping clogged pin beast. The owner / operator has been re piped as well.
I have thoughts of getting snowed in and spending some quality time insulating that , one thing at a time lol.hvacfreak

Had a few adjustments to make when I saw the first photo from this view. Light , shadow , and the old system seem to want to tweak my piping. What was straight yesterday is tweaked today kind of thing , lol.hvacfreak

Looks good. Make sure the system is tight with good air vents.:NYplumber:0

Really nice clean work, I like how everything squares away nicely0

Your Pressuretrol is also crooked.
It may be the picture but, it looks like your header is pitched back towards the risers instead of towards the equalizer?Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

Beautiful job, btw. Another inspiration.

Thanks everybody , much appreciated. I didn't have a plan I just dove in and started turning. The system connections ended up right in the header kind of , and it forced me to be more accurate than I wanted to have to be.
The header is just cutting into the bubble with the low side toward the equalizer. The lighting and the fact that my iphone seems to take weird pictures of the piping down there maybe.
I'm almost finished with the steel pipe , hopefully I can get the other stuff done faster.

Thanks Fred.
The reducer on the flue pipe was a little large on the 6 inch side ( 3 screws jammed into the top of it ). Time to build a fire.hvacfreak

#1. what's the plate on the right top of the boiler, with the brass nipple sticking out? Whats the purpose of that whole plate? I have the same...
#2. Could you please take a side pic of your LWCO?
#3. I'm sorely jealous. Install looks awesome.0 -

@mookie3333 , that plate is where a hot water coil would go, if you choose to but one in, the plate comes off. Why they put the brass nipple on there, I'm not sure but someone on here will know.0 -
Thank you very much Bob.
Thanks mookie3333 , the brass well is for an aquastat to fire the boiler on a call for domestic hot water. I didn't get the tankless coil but the aquastat comes with the package. I was playing with the idea of using it to control water temp. for skimming since I have it anyway. It's just acting as a pipe plug at the moment. Also , I was not on anyone's clock doing this so I had time to do some stuff that might not be typical ( IF my install looks better ) , but I'm like anyone else and appreciate the compliment . I'd be fired on this job in the real world , lol.hvacfreak

Fire in the hole bros !!! We got heat !!! , Well at least for 1 cycle.
Mookie , are you a Ravens fan by chance ?
I checked the dimensional settings , set the air at starting position , set fuel pressure and let er eat for a couple of cycles. I'm going to save up some scratch and see if I can get a real burner man to set this up. I will dial in the smoke and stack temp and draft checks tomorrow , but my best is really only close. Burners are a " craft " , I got my thing and burners aint it. But man it really was cool watching her run . Oh , if anyone ever pipes one of these don't forget to plug the optional front return opening , lol.

Nice job sir. BTW, I see a Cyclegard displayed in all its glory...is that staying in the installation or are you replacing it with a Safgard?Peerless 63-03, 118,000 BTU (308 sqft), single-pipe steam system connected to 286 EDR of radiation, 30ft of baseboard and indirect DHW

Thank you all.
It's just the cover. It was a reply to a previous post and just some bad humor overall , I can't stand that device.vr608 said:Nice job sir. BTW, I see a Cyclegard displayed in all its glory...is that staying in the installation or are you replacing it with a Safgard?

Yea, its a shame that the Safgard doesn't come standard. I believe they cost the same, so price shouldn't be an issue.Peerless 63-03, 118,000 BTU (308 sqft), single-pipe steam system connected to 286 EDR of radiation, 30ft of baseboard and indirect DHW

Shoot , thanks Dave. I just did what I read on here , and Dan H. since the early 1990's. And thank goodness the weather held out for me on this. Your system in your signature line sounds intense.hvacfreak
