I noticed that i have a Air Elimination port on top of my steam boiler. The port is capped but there is a note thats says it is optional. What is this air elimination port? I believe i have a 1 pipe gravity return system and I thought venting just needed to occure at the end on the mains and the radiators. Is there any advantage or disadvantage to incoorporating the vent on the boiler?

    That tapping is for when the boiler is trimmed out and used as a hot water boiler.
