Most radiators have bleed screws at the end farthest away from the supply. You turn your thermostat up to start the circ pump then loosen the screw to allow the air out. If you do this to the last radiator on the line it should remove the air. Some installers add a quick bleed valve on the return line by the furnace. This is just a tap. You can hold a bucket below this and open the tap very little. you will hear the air come out. When you no longer hear the air close the tap tightly. You should check the pressure guage on the furnace to make sure your feed is working, If you have no pressure you can lift the arm on top of your valve to manually allow water in the furnace Do not allow the pressure over 20psi so that the pressure release does not blow off when the water heats.

Why do you get air in boiler?
Few answers to this, dependant on system type + fittings etc. the most common is an old system, in need of a good clean- corrosion of the metals cause by the oxygen in water reacting with iron in rads, you get ironoxide (rust) and hydrogen. so the most common answer is its not air its hydrogen, be careful but you can open a bleed on a rad slowly and hold a match, if it lights, I was right =p
What is the difference between an air bleed valve and a pressure relief valve on a boiler?
They serve two different purposes. An air bleed valve is used to remove air from the circulation system. A pressure relief valve is designed to automatically open when certain pressure levels are reached.
