I've recently had to drain my wood boiler to a level below where a former HW Coil was in order to replace the rubber gasket. Now I have air in the entire system. I have an automatic water feeder on a system which has 5 zones. What is the best way to bleed the air from this system? I have shut off valves on each zone so should I close all valves and proceed to open and bleed and close one at a time? If so where should the lever on the feeder valve be straight up or laying down?
If there is a better way to do this i would like to hear from anyone.
