How do i re-pressurize my Ideal Isar HE24 boiler?

I have recently had an ideal isar he24 boiler fitted but over the last couple of weeks the pressure has dropped varying from 0 to 0.5. The heating still works but is sometimes noisy and often the pressure needle shoots up and down as it makes a noise. My previous boiler was a swiftflow and the pressure could be turned up by the turn of a screw. I thought this one might be as easy but not sure which screw to turn.

try locate your filling loop, usually a flexiable stainless steel briaded hose with a small black lever handle. Slowly open until your pressure is between 1-1.5 bar.

If pressure continues to drop, you have a leak somewhere, or you safety valve is lifting letting water out (check the overflow outside)

Do not run your boiler with low water, the bangin your hearing is know as kettling, the water volume in you heatexcahnger is so low the water is being allowed to boil and will not do your boiler any favours.
