Hi people. ..my daughter has just moved into her first house and we are trying to work out the boiler settings...the only thing we know is it is a SAUNIER DUVAL I cannot find a model number anyone on it though....there is one flap that opens which has the controls .....I have looked for the manual on the SAUNIER website (there are a lot)...so need some advice/help ...hoping someone recognises the model from the pics.....cheers
