Hi, Im fitting a new combi boiler in place of the old system, ive managed to trace and remove all the old pipes that i will not be using anymore. Ive fed the cold, hot,ch flow and return pipes but the only problem is trying to work out how to attatch the filling loop and the double check valve that came with it. The CH OUT connection point is fitted with a valve but also has another thread for fitting another 'thing'. I cant work out what why to plumb this in. The boiler is a FERROLI F30
Any help appreciated
