Hi
I have a 28CDI
DHW works fine
CH demand comes on and boulder will work for a few min
The the flame is shut off - CH light remains on, pump still running.
After a while fires up again for a couple of min - repeat... Repeat ..
Only heating the nearest rads.
Flow out of boulder hot
Return Luke warm - so it's not up to temp.
Any ideas ?.
Vent problem ? - fan seems to be running
Overheat ? - how do I tell ?
No flashing lights - so difficult to diagnose..
Ant help / advise would be great - don't want to get ripped off
