Mend Ariston DIA20 Manual Boiler Service

How can I get operator/service manual for DIA20 combi boiler?

Looking to download service and operators manual for Ariston combi boiler DIA 20 MFFI CE to hard wire in a room stat and to service it and to work the hideously complicated (to me!) timer/programmer on it. Thanks for any info.

I've got the same model and the same problem! When an engineer was here he left me a phone number for Ariston to call and ask for the manual, only I have since lost the number :-( . Surely by calling around it can be found?!
