Looking from the front of the boiler you will see 5 copper pipes underneath going into the boiler . Two are for hot water ,two are for central heating and one for gas in. you should also see a flexible pipe looping between two of the copper pipes with an on/off lever valve on each. whilst looking at the pressure gauge (small needle dial from 1 to 4 you will need to turn both lever valves to the on position and you will see the needle gauge pressure rise. Once the pressure has reached between 1 and 11/2 turn the lever valves to the off possition. You may find that you will need to bleed your radiators to remove any air trapped

hi
it depands hoe the boiler was installed. some people add an external fill point which will be a 1/2" braided hose with a valve either end, or it will be a wachine machinetype valve/querter turn ballvale up tight under the bottom of the boiler. simply open open until you reach your desired pressure.
