I have now solved my three dead legs by putting valves on the end and
then bleeding air. (Thanks for the tip!) The combi boilder now does
not fire when I use the cold water system.

However, the boiler still seems to fire for a couple of seconds every
so often (haven't timed it but it seems to be about every hour).

My only explanation is that this is the pre-heat function keeping a
little reservoir of water warm. Am I correct? If so, does anyone know
how to turn this functionality off on a Glow-worm CXI combi??

Thanks


Provided we are talking about a model with GCN 47-047-23/24/27 a GW nn
CXi Combi then look in the manual you'll see what to do to stop the
preheat function?
