Does anyone happen to have a manual for one of these to hand please ?

(I don't know which specific model it is from the range atm)

I'm just trying to work out what's making it run so noisily - the rads
are bled, but even with them off it sounds like it's pumping a huge
amount of air around the system (gurgling like a b*stard to be more
precise)

I've just tried to lower the temp at the boiler end in case it was
kettling causing it (don't normally notice if it is, as it's in a
garage)

I prolly have one, but I doubt it will be of much use for what you're
describing

If you have a leak somewhere that's letting air in, it could be anywhere
in the system not necessarily in the boiler

You might find that your auto bleed valve isn't working properly, it
will be somewhere at the top of the boiler and is usually gold in colour
and circular with a screw top an inch and a half in diameter and two
inches tall

Check out the joints in the boiler to see if there is evidence of water
leaks especially around the heat exchanger

The only other (continually) moving parts in the boiler are the fan,
and the pump if its part of the boiler
