: You've been given references to drawings of systems and pictures of where the parts should be to get air out including the methods. Either valves are in the circuits to close so you can force new water against them and out a drain valve nearby, or there was an opening at the topmost circuit. You might be missing them. It might take a visit from an experienced plumber to find them and point out how to use them. Writing descriptions over the internet is not the best vocational instructional method.
I will try one more time..., and I do agree that there are obvious limitations to vocational instruction over the net...
I have looked at the reference drawings. Good drawings, except they show diverter valve or purge cocks, or vents that my system DOES NOT HAVE. I know it doesn't, I have had the covers off of every baseboard radiator to paint them recently. I have looked over every inch of the system, and have mapped out every run, every T, every valve, baseboard, return line etc... There are NO openings of any kind in the topmost circuit...just a drain at the bottom of the boiler and an automatic air bubbler on the manifold outside of the boiler in the low part of the system. (I have been involved in homebuilding most of my life... not just a green horn owner.. they aren't there.).
Please explain what you mean by "valves are in the circuits to close so you can force new water against them and out a drain valve nearby". Perhaps this is where the limitation of the net comes in for vocational training, but you seem to be using phrasing that seasoned hydronics systems people would understand that just don't make sense to others...
Your either/or explanation would indicate that if I do not have valves or vents or other openings in the topmost part of the system to vent it, then this other set up must be what I have... But your explanation of this system to force water against valves doesn't make sense without hand jestures or a video...
