If the system has sufficient pressure at cold fill time (4 to 5 psig at the high point) and your circulator is drawing away from the expansion tank location, you should not have air problems. Is there an air separator, air vents at the very high point and/or a purge station?

Not sure what you mean by air vents at the wrong location. They need to be at the high points to be effective, otherwise you are going to have to purge.
