I have an OWB with a heat exchanger hooked to my oil furnace. My heat is hot water that runs through cast iron radiators for zone 1 and for zone 2 the water runs through the baseboard heaters. Just fired up the OWB and blead the air from the lines in zone #1 by cracking the cast iron heaters open. Zone #1 is heating fine, however zone #2 is cold. I felt the pump and it is running fine. Do I have an air lock in this zone or what? How do I bleed the pump for zone #2? I didn't see anywhere in the piping for this zone where there is a bleeder of any kind. Any help would be appreciated.
