I hope someone can help, I've been freezing my arse off for the last week
:-}

I have a Saunier Duvall SD620F combi boiler. The central heating pressure
gauge is reading zero and the little documentation I have on it says it
needs to be refilled by a qualified engineer.
Thing is though I'm out of work and engineers charge more per hour than I
get in a week. Can anyone tell me what valves or taps need to turned to
fill
it back up ?
I've bled the radiators and there was a heck of a lot of air in one of
them,
but it hasn't made any difference. The central heating timer's been
switched
off for a couple of days but the pilot light is still lit. There's no
running hot water either, goes without saying I suppose.

Can anyone help, please ? I'm *freezing* here!


There should be a flexible hose somewhere on your system. Either under the
boiler or somewhere along the pipework. If it isn't already linked up,
relink it & open the tap until the pressure on your boiler reads just over 1
Bar. Re-bleed your rads & if the pressure has dropped again, repressurize to
just over 1 bar again.
You might have to do this a couple of times over the next couple of weeks as
the hydrogen is driven out of the fresh water you have introduced into the
system.
