We have just added a new radiator yesterday to our system and went to turn the boiler back on and the flame won't ignite. The system sounds like its working but won't ignite the flame, any suggestions?

There is no reason why it should not re lit, you may have an air lock because there is a flow swich in the boiler and air will not make it move, is there an air vaule on top of the boiler? if not crack the nut on the return pipe to let the air out
