Air in circulating system

I have a Gas heating system,two zones, propane..had to replace one circulating pump... it was necessary to drain the system..I seem to be unable to remove the air in the system controled by the new pump...This is an older home and there are air valves attached to the radiators in that system and I am able to bleed them...but not so in the newer system... The pump works but is not circulating the water... How can I bleed that zone?... thanks

Air in system

Somewhere above the circulator should be a shut off valve & another valve with a garden hose connection. Turn off the valve, attach a hose to the valve with the garden hose threads. Open the garden hose valve (boiler drain). Allow water to flow until you don't get bubbles. If you can take some pictures & provide a link to them it would be a lot easier to explain.
