Re: Getting my 1924 system going again
And just a side note - if the system is really at slightly over 7 psi, that's roughly the static head from the 2nd floor. It's roughly 15 to 18 feet higher than the boiler pressure gauge. And 2.31 feet per psi, that's 18 / 2.31 = 7.8 psi.

Re: Inefficient boiler heats basement. Should I keep basement door open or closed during winter?
They never fail during mild weather but always when bad weather is upon you. I need one NOW is never cheap and always rushed.
Start the process, get it sized properly, have the contractor chosen and get it done while there's time to do it properly.

Re: CIPP Health Risks/Sporadic Sewer Odor/CI Durability
@Jamie Hall Could that 'floor drain' be instead a hole in buried 70 yr old cast iron pipe, about 25 feet of which is buried in cement? We have also found that when they built the house trap they built access pit very small 11x7 x15D. The fresh air inlet is accessible but the hub that the outward trap flows into is buried in cement. But in case you say that's not it, then I'll have to look at the original house drawings—though from 1924 to 1955, house was on a septic tank. Perhaps if THAT was incorrectly sealed that could be the odor source, but why only occasionally? I should get this cleared up before the sewer lining.

Re: Lochinvar Knight Boiler Flame Fail Ignition Errors - ready to pull my hair out
I think plus or minus depends on which port you are using since I think it measures differential between the 2 ports.
Does the tag on the appliance regulator say what the factory setting is? That looks a lot like what you would set it for for natural gas.

Re: Steam boiler needs replacing?
Agreed. When @EzzyT gets there he will want to look for buried returns (which are almost always leaking), leaking vents, loose packing nuts etc.
Re: was this old boiler gas or oil fueled?
I dont see any asbestos there. All the insulation is gone by the looks of that pic. As far as where the fire box used to be, and any asbestos insulation near that chamber… that part is also gone. the side with the flue collector is the front or back and the side with plate bolted on it might have some gasket or furnace cement between that plate and the boiler. The top is the part where the rag is stuffed inside the supply pipe tapping.
The actual heating unit's bottom was a box that was the length and width of the blue steel boiler that held the water and about 18" tall. That part that is missing is what held the fire box, or combustion chamber. The oil burner or gas burner would be mounted in an opening designed for it. Since that part is missing, There is no asbestos to worry about.
The brown "Fire Box" at the bottom is where you might find the most asbestos insulation. But since you done seem to have that part, …
Re: Sight Glass- Steam Boiler
When I had steam I added a drain per the video from Silent Steam team. The Dahl 521-61-04 is the valve I eventually stuck on there. The lower portion of the sight glass fitting always seemed to have some crud to flush out no matter how clean the boiler water was.
