Air vent needed here?

in THE MAIN WALL
I'm used to seeing an air vent here.
Is one needed if there is another air eliminater in the loop?

What is the typical size for an eliminater located here?
I also am used to seeing them on top of the indirect water heater.
Is that typically a 1/2 mpt?

    Yes that boiler comes with one specifically for that spot. It takes the air out of the H/E.
    That one comes 1/2" for that tee.

    What type of PVC is used for that exhaust?
    Is it foam core PVC or Sch 40 PVC?

    Not sure, didn't look closely at it.
    I can check tomorrow.
    Does it look off?

    "Not for pressure"
