Re: G125BE burner conversion from blue flame to Riello
I did one on a temporary basis once because the tech before me tried to remove the burner and smashed the porcelain blast tube against the block.
It's the same exact casting as the G115, but yes, baffles will need to be removed or adjusted to bring up the stack temp.
If you have the Logomatic 2107, then nothing else needs to be done.
Get an OEM Riello for a G115/3, or /4 or /5 depending on what yours is. OEM is kind of important here because there are different blast tube lengths and insertion depths for each.
Since combustion air should already be there, (in the lower right rear corner) you can easily connect it to the BF Riello or the F with the fresh air kit.
Is it chimney or sidewall vented?

Do you mean you plan to run it waist high? It's at head height now, right?
Waist high is not good. You don't want it near the boiler water line. Far above it, or far below it is what you want.
Re: Using a hot-water radiator for one-pipe steam
A 2' wrench or even an 18" from harbor Freight is cheap and with a cheater pipe it will do anything a 4' will do an a lot easier to handle.

If it is a return it has to be under where the steam condenses in the main and the emitters, the water can't flow up hill.

If you raise the pipe it will probably trap water and you will get water hammer. But we need pictures to tell for sure. Chances are if it could be raised the original installer would have done that
Re: What type of Vent on pipe near boiler in basement
@mattmich and @ethicalpaul , the other part of the equation is……. balance.
You want the steam to reach the ends of all the mains, not only quickly, but also at about the same time. Once you accomplish that, the steam is available at every tee where a radiator connects, and will rise to all the radiators at the same time. Balancing the heat in all the rooms is easy when you do it this way.
This is where "pipe math" comes in. Once we know how much air is in each main, we have our starting point for sizing vents. Occasionally we need to make changes from the original sizings, but having that starting point gets the job done faster.
Re: Turning off power to minisplits
Could be a crankcase heater to keep the compressor warm and keep the liquid refrigerant out of the compressor. No harm killing power but they used to recommend 24hour CCH warm up before starting. Probably doesn't need to be that long but it is what it is.
Re: another copper press fitting peeve: street female adapters
For commercial repairs I think the hot work permit process is driving service people to press options.

Re: Need Steam Specialist in Portland, Maine
Who installed it? Not that old. Piping doesn't look horrible from what I can see.
Someone here may know someone in your area. Portland is a large city there ought to be someone. Maybe check with some P & H supply houses to see if they know someone who knows steam. Steam Experts are dwindling. Maybe @New England SteamWorks
Re: Bad homeowner steam advise= $$$$$
The pressuretrol got a workout, sure, but it stops the burners
There is no way 90% of all the produced heat went up the flue
Anyway we can all be sad about the house going down but I don’t see the boiler being responsible. Sorry for the disruption
