cheers ed, interesting, i didn't know they were so high maintenance
objects! are they a needed piece of kit or just a glorified toy to make
things simple? with todays trend towards zero govenors and room sealed
appliances is there any point going that deep into things, most of the
time the manufacturers want you/customer to buy a new appliance. i think
soon it will be easier and possibly cheaper to throw the old out and get
new in.

I found it essential for getting my Keston Celcius 25 setup
properly. The claims in the manual that the mixture was
correctly adjusted prior to leaving the factory were so far
off that it didn't operate correctly until adjusted.
OTOH, lots of CORGI engineers seem to manage without one.
If you are just installing one boiler, you would possibly be
better off hiring one when you do the commissioning. If you are
servicing a few boilers a year around your family, then it may
be worthwhile to buy one, although once the mixture is right,
I've never found a boiler needs any more adjustment on a
subsequent service.
