greenstar24i boiler presure ?

what should pressure gauge read on greenstar24i junior conden boiler its aproaching max on green band and heading for second red band
p kirkbride, February 2010
pressure should read 1.5 bar pressure with system cold ,, this pressure will increase slightly when boiler operating but if it goes up to 2.5 or 3 bar there is an expansion problem with either the hose or the expansion vessel
