HELP - NO ONE can figure this out!! (STEAM System)

KC_Jones - that is extremely generous of you! I assume we will take you up on that offer. I just need to talk with my husband. We are also trying to get someone scheduled to skim the boiler as has been suggested. And we are replacing the vent on the baseboard unit (should be here today) since taking it off altogether seems to get it heating. But after the weekend I will reach out via PM. Thanks for your kindness!
