take front off boiler so you can see the internal works,find the pipe that goes through the wall it will be 15mm pipe trace it back to the boiler there should be a red cap turn it till you hear water running reduce the pressure to required,be carefull it possible turn the boiler off at fused spur as the electrics will be live and you could get a shock

you need to locate the pressure relife valve and let some water out by turning the knob on it.
