Main vent

Hi,

I have two big main pipes coming out of the boiler one covers back of the two story house and the 2nd one covers the front of the house. About 30 feet away from the boiler, the pipe covering front of the house has a air valve Hoffman #41 angle 1/8.

is this main valve? Is it a wrong valve for the main pipe.

I also have a air valve in the boiler room, on smaller then main pipe, I think it is on return pipe, why is it there? Is this main valve? Which one important?

Thanks
