Re: She canna take any more, Cap'n! She's gonna blow!
I assure you there are no other air eliminators in the system. Also all the components are connected per “pumping away” - boiler supply, air separator connected to water feed & compression tank, circulator. Pretty much by the book.

Re: oil boiler seems clogged, no flow
She's up and running. I rigged up these fittings and slowly increased to a steady 80 psi and then I started hearing hissing which I'm guessing wqs coming from the pipe right outside. But at the same time I also filled up the filter canister with oil so that could have been the problem as well
Re: sight glass issue
The reason you shouldn't shut both the hot and cold water off to the coil is I don't know if you have a pressure relief valve on the coil.
If you shut off both valves and the coil is full of water the water will get heated when the boiler runs and expand and possibly wreck the coil.

Re: sight glass issue
turn off the cold feed to the dhw, leave the hot water side valve open and leave a faucet open somewhere. That will keep no pressure on the tankless coil. If it still rises it is the manual feed valve that isn't holding. It is likely you can hear it if it is leaking that much too. If there is a union above the water line but after the valve you can open that and see if water is running out there as another test.
Re: When did pressure relief valves become standard?
As far as pressure relief valves, they weren't needed on hot water systems until they went to closed compression tanks from open attic tanks.
Re: steam vs vapor system
Exactly. However I do need to do some maintenance to the boiler over the summer when it's not running. Needs a new combustion chamber and then I want to have somebody come in and do a combustion analysis and efficiency test the last time that was done was 2012
The Duke Mansion Mystery
Not long after The Lovely Marianne and I started that little business of ours in 1989, a caretaker called and asked if I would be willing to consult on a problem hot-water-heating system in what he claimed was “the biggest house you will ever see.”
