if the pressure is to high how do u release it?

i have a ferroli combi boiler 80E i think the pressures to high, how do i release the pressure so the boiler works?

pressure can be as high as 2.50 bar and still work your prv(pressure relief valve) will relieve any excessive pressure after that,the problems you could have is-1 pressure passing through the bypass valve into the heating side of the boiler,-2a faulty prv and not letting the excessive pressure escaping-3 and finally a faulty expansion vessel letting the water expand when heating up thus showing high pressure on the guage.

high pressure will not stop the boiler working [only low].... u can release the pressure via a radiator bleed valve into a bowl
