I was here a few days ago, stating that my service men said i don’t have main venting, A lot of people here found that hard to believe, and sure as crap i think i found it. Should there be more or is this the only one ?

    I forgot to mention, this main vent is around the vicinity of the second floor radiator, this is the last radiator in the second floor

    that is a vent, whether adequate or not, TBD,
    would need to understand the rest of the system,

    there could be a vent for each main line leaving the boiler,
    or for a common return point,
    all depends on your system,

    are system pictures,
    boiler, rad type, wet/dry return
    posted on another thread? link?

    the one upstairs may have been added to make up for other issues,

    That’s the main i see. There one radiator directly above the boiler. i didn’t see anything on there. I traced the one that went to the sun room and it was a straight run. then i traced this one that went to the upstairs rad and found the vent. then below the vent i see a drop off that i assume goes to the wet return?
    How do i get that vent off? It’s fused into the threads, but i can’t get it off

    penetrating oil,
    kroil,
    a dab of tranny oil,
    even 3 in 1,

    and a good fitting wrench,

    I think my queston from the other thread still stands,
    neilc said:

    how many feet of pipe is there between the boiler, and the farthest radthis vent, a pipe diameter aslo?

    a street 45, a nipple and 45 might swing that vent location to a more open spot there, where a larger vent may fit,
    actual sizing/specifications aren't my specialty,
    length and diameter and others will jump in.

    went back and read that thread again,
    where you say the thermostat runs past setpoint,
    what type thermostat?
    and, if applicable,
    what heat type is it set for?
