there should be two connections for a flexible hose to connect to(fill loop) when connected open the valves which will bring the pressure up .if you keep losing pressure you have a leak which requires attn as you should only lose pressure when you are draining the system

See if you can find the filling loop - thats generally a flexible stainless steel pipe that connects the boiler to the mains water supply. The filling loop will have some sort of a tap on one end, either hand or screwdriver operated. Once found, open the tap and watch the boiler pressure rise. Don't overdo it!!
