MAIN AIR VENT: for down flow systems or diaphragm type expansion tanks (not provided) Before a system is filled with water, there is air in the pipes and radiation units• Some of the air will be trapped as the system is filled. It is possible to eliminate most of this air through the air vents on the radiation units• A main air vent will speed and simplify this process. The main air vent should be installed on the highest point in the supply main when all radiation is below the top of the boiler
