You will probably have to install a tee in your "radiator" at the high point to vent the air. 1-1/4" pipe is hard to vent by pushing the air with water even with a purge valve. The volume of water needed to purge is greater than the average purge valve can handle sometimes.
A tee with a reducer and a 4 inch nipple will make a great air collector. I will often use one and put a elbow on top and extend my air vent to get easier access. you can vent with a small ball valve or coin type air vent.
