you should have a filling loop somewhere on the system, will look like a braided hose about 30cm long, normally underneath the boiler, but could be anywhere! where its connected to there will be either 1 or 2 isolating valves, open them up until the boiler reaches about 1.5 then shut them off! hope this helps?

KAW!

your system needs topping back up to 1.5bar and your rads will need bleeding.
