Hard to tell by the pic's, but the faucet should be between the ball valves at the very end of the return before the last ball valve. The way I would do it, coming out of the boiler hot, 1 air scoop/ exp tank, 2 flow check, 3 ball valve, 4 pump, 5 ball valve, 6 heating element, 7 faucet, 8 ball valve to boiler return. When purging air, close all ball valves, open the fauchet attached to a garden hose, open the flo check, open the ball valves at the pump but leave the one on the return closed and flip the lever on the pressure reducing valve to give full house pressure to push the air out of the garden hose to a drain. Close the faucet and all the ball valves and do this for every zone, 1 at a time. When finished open all the ball valves and set the pressure to around 12 in most cases
