Your pressure is a little low, but this isn't a real problem unless you have a multi storey house...its best to fill your boiler a little, and to do this you find the 'filling loop' (a flexible pipe connection that connects your boiler to the water main). The filling loop will have some sort of tap on it, either hand, screwdriver or small spanner type and you open this tap very slowly. You'll hear the boiler starting to fill and keep an eye on the pressure gauge until you reach just between 1 and 1.5 bar. Don't overdo it though!
