Just for all you novices, such as myself. A friend suggested i look up the manual on the internet. It came up under Potterton.co.uk and i was able to read it through adobe acrobat which was a lot better than having to buy it! It simply said to turn all the dials on - thermosat, timer and both central heating and water. Turn boiler dial to '0' and the turn it to 2 or 3 for summer use. It took a little while to spark but turned on after that. Going to turn off the central heating in a few hours just so that it keeps going?
