Turn all the others off and see if it pushes the airlock through.

if that does not help...u can (hopefully) remove the airblock by draining down from the new rad (u did fit a drain valve ?) for about 10 secs or thereabouts...u should hear the air move along...
open the drain valve fast...helps jolt the air lock.
as u say u have f &e system it will top up itself...

A simple test is to first isolate the towel rail by turning off both its valves.

Remove one of the blanking plugs at the top and replace it with a hose connecter adapter and connect a hose to it and put other end of hose in the toilet.

Opening either valve should give a flow of water out of the hose to confirm there is no blockage.

If there is flow from each valve then after refitting blanking plug it should work but keep your fingers crossed! If not then you may have done something very stupid with the pipe connections like putting both onto the flow side.
