Guys, anyone got a manual for aplha 240e, just added a rad to system other day and now boiler howling like dying a painful death on dhw, did use everad inhib which i drained out again incase it was foaming up in primary heat exchanger, now going to look at plate-plate after that diverter valve but wondering if there are any filters etc so a diagram would help me out in a big way, have check gas pressures and everything fine and it gives 9litres a min with correct temp rise
