I figure you've heard this a thousand times, but when hear a glug glug glug as the circulator pushes water to the baseboards. I dont have any air release valves along the lines or at the baseboards. I'm maintaining 12psi whether the system is circulating or not. I've downloaded the manual, but it is vague where I should purge the air from. Is the air purge at the top of the pipe near the extrol tank, or are they located at the elbow just before the circulators after the isolation valve? Thanks for any help.
