Re: Purging air
As Bob has said that silver automatic air vent MUST BE removed. I am sorry I missed that at first.
The water cushion in the steel compression tank is gone and the excess water in the steel compression tank must be drained out of it to allow it to work properly and create the point of no pressure change.
It's better to drain the boiler and then crack the drain o tank valve in the steel compression tank to allow it to be filled with water to the right level. When there is nothing but water coming out of the drain-o-tank valve you need to shut it off and shut the water fill valve off.
Afte that you can restart the boiler.

Re: Questions about a steam system
So, water is only half way up the gauge glass, but the system was heating?
I'd think it's pretty clear it's not a hot water system.

Re: Need help with Radiant How to go laying panels over existing floor
viega and Uponor have a thin over the top board, it uses 5/16” tube you would need to fasten them to the concrete somehow and floor over it.
35 btu/ sq ft is kinda high for radiant floors, you will need to run a high surface temperature
Radiant walls and ceilings are sometimes easier to retro fit
Panel radiators are another option

Re: Questions about a steam system
Thats not a condensate pump. Can't tell if that pump is hooked up or not.
Steam for sure maybe with a HW zone off it.
Re: Questions about a steam system
That pump and those air vents make it a hot water system. Reinstate 15psi pressure.
Re: Questions about a steam system
I'm not at all convinced that that is a steam system. Modified gravity hot water, maybe? Which would explain the air vents on the radiators — and the 15 psig.
Re: Loud banging when heating STEAM HEAT
raise the radiator a 1/4” or 3/8” on both ends and see what happens

Re: Bell & Gossett Circulator
You'd have to get a plumber to install a standpipe, pretty much with any heating contractor. the might subcontract a plumber, but installing a standpipe isn't heating. most contractors would just run it to an existing drain somewhere in the basement.
The deal with the devil that you've made for the utility to install the equipment is that the contractor works for the utility, not you.

Re: Considering replacing Beckett gun on 35 yr old Weil McClain boiler
$200.00 for the AFG oil burner on eBay is not such a great deal, considering that junk and scrap metal dealers seem to get hundreds of them for the price of the weight of the burner in mixed metals $$ per pound. Any plumber that installed gas heat will have access to those burners for free. Just hang around a plumbing company's shop at the end of the day and you may find someone unloading an old oil heater with burner that will cost you nothing. But that may be a hit or miss situation.
What oil burner is currently on your heating system? Beckett made the AF burner over 45 years ago and the parts for the AFG burner fit that same housing from the 1980s. For the price of a Fuel Pump (less than $70 on eBay) or a solenoid valve you can get the positive cut off that any new oil burner has. You can replace your primary control to get the interrupted ignition and pre purge features to work on your existing oil burner.
The only thing your older oil burner may not have that a new burner can offer is the flame retention design that makes the oil burn more efficiently. If your existing burner is not a flame retention design and is using the older 1725 RPM burner motor, then you may get better efficiency with a newer burner.
So, knowing what your existing oil burner is will determine if the $200.00 eBay burner is worth the investment.
