How do I bleed the pump on a Chaffotteaux & maury calydra 100/sentinel 100. i have recently removed and then put back a radiator. however there does not seem to be any water flowing through the system and the boiler will not start/ignite. The pump is moving but not pumping around.

yes but there appears to be no preasure behind it and no water flows thro the loop

Have you refilled the system using the Filling Loop???
System pressure should be about 1-00 Bar
