How can i raise the pressure on my boiler, It's a Vokera 20/80 RS Flowmatic. Thanks

Some where close to the boiler there should be a "filling loop" two small taps either side of a flexable pipe, one side of the pipe should be disconected, reconect, open both valves to increase the pressure to one and a half bar, close off valves and disconect pipe, check for leaks on the system
