Usually there is a panel on the boiler that opens up/pulls away and there will be two pipes joined together by means of a hose/pipe, this will usually have two valves or taps on it.
Remove power to the boiler first.
If you turn both these valves/taps to the open position, it will fill the water in the heating system. The system will have a pressure meter and will have a desired region, usually between 1&2 if I recall, usually also in green. Fill the system until the needle is in this region.
Once filled, turn off both valves and turn power back on.

I love how different this is depending on where you live. Have topped off a bunch of different boilers in the US never had to open a panel to find the fill valve. Always commercial boilers or single family homes in a high heating load area.
