    You need to stand farther back so we can see. That looks like a boiler return trap. The street elbow on top is your air vent. I see some cross over traps.

    That is a vapor system. What problems are you having? You have to run that at very low pressure.

    Others that know more about vapor will comment @Jamie Hall

    I'll comment quite happily -- when I can see more of the system. And get a better idea of what is connected to what...

    Floor to ceiling shots of piping, several sides would be good.

    Might be an air trap rather than a return trap. There may have been a check valve installed in that street 90 to hold vacuum, which worked quite well when the system was coal-fired.

    Have you found any manufacturers' info on that unit, or anything else on that system? Where is this system located?
