Trouble shooting guide required for Ravenheat 820/20 combi boiler?

Does anyone have a copy of this user manual/service guide/trouble shooter they could email me.

My boiler is on the blink (no hot water or central heating), luckily my father is a Corgi registered fitter (he can do pretty much everything where-as I can use a pc!) but I can't find the manual with the wiring diagrams etc. I've tried the Ravenheat webpage but it no longer lists this model.

If you can help please email on nick_king@blueyonder.co.uk

Many thanks,

Nick

is there 240v to pump and is there 240v to fan or 90v ,ensure pressure is above 1 bar , remove hose from air pressure switch and suck whilst calling for heat, if the boiler fires and there is 90-110v on the fan it is your circuit board,
