Re: Equalizer size physics
Not a problem at all. Reddit is not necessary the best source for accurate information.
Re: Weil-McLain EG/H: thermostat and pressuretrol shut the damper, but not the spill switch.
So here are two other variations. The first example a tripped Blocked Vent Switch will close the damper. A tripped Flame Rollout Switch would result in the damper staying open.
In this case a tripped Blocked Vent Switch (SSW) or a tripped Flame Rollout Switch (RSW) would result in the damper staying open.

Re: Hot water line in steam boiler flashing fix
it’s actually so easy that even I did it
Re: Boiler making a 'churning' noise when firing
Look like a genus installed ,piped wrong and god forbid you have to remove any burners .Who installed the boiler w the front facing a wall ? It looks as though the hartford loop is remotely installed instead of off the equalizer drop again a public school grad not reading instructions but the copper pipe gives it right away . Typical a good install in reality you need some one to re install that boiler correctly the performance and your fuel consumptions will tell the tale . Most likely its has a good deal of mud and rust in the boiler hence the churning noise but some will stay unnecessary but usually a good wanding and flushing of the bottom of the boiler and flushing of the return piping will help . Your performance will only as good as the near boiler piping but as most know steam is quite forgiving and will usually work even if installed improperly unless by some one who has a clue then there issues but when a hack installs it works perfect 'one of god miracles for sure and in complete opposite of murphy's law .
peace and good luck clammy

Re: Attached EDR vs Boiler SF of steam
If the radiation can't keep up it doesn't matter how big you make the boiler it'll just keep cycling on pressure.
What pressure was your boiler running during this event?

Re: Attached EDR vs Boiler SF of steam
So your bathrooms and kitchen were all below 32 degrees ?
I would not size a boiler on deficiencies with the building. I'd fix the deficiencies with the building.
If the heating system can't keep up to your satisfaction you may need more radiation and a boiler to match. or just improve the building (or strategic places) which is a one time cost, fuel is a continuous cost.

Re: Steam Sizing Question.. what would you choose?
Just curious, what exact model is the current WM boiler?
Re: Steam Sizing Question.. what would you choose?
I'm not a steam guy, but does the current "original" boiler in question still actually function? If so, can you go back to the house and check how the system is performing for yourself? Then you would know if all the rads are getting warm enough or not. Instead of relying on the guy that "doesn't remember"

Re: Steam Sizing Question.. what would you choose?
60,000 undersized and 72,000 undersized, is exactly the same thing, IMO. Especially for a system that size.
Re: Steam Sizing Question.. what would you choose?
Is this 1 pipe?
The radiator not heating is likely some problem other than being undersized. You are only consuming that much steam if every radiator is heated fully and that rarely happens. I would go with either boiler and make sure I have all the near boiler piping correct, drips at the boiler if it is counterflow, mains individually connected to the header rather than teed together at the ceiling, using both boiler outlets if available, possibly using a drop header. Insulating the steam piping.
You have close to 0 pickup factor at 282k btu/hr but there is also some measurement error in everything.
