If the pressure gauge reads more than 1.7 bar as a result of over filling:
▶ Bleed one radiator until the pressure gauge returns to between 1 and
1.7 bar.
▶ It is good practice to bleed any excess air that has entered the heating
system due to pressure loss. Locate and open the radiator's bleed/
vent point, closing the valve when water begins to flow.
▶ If, through normal boiler operation, the PRV pipe starts to leak, it
could be a sign of system pressure being too high. In this instance
please bleed a radiator as described above.
Semi-sealed heating system
Appliances that can be connected to semi-sealed heating systems will
have the pressure maintained automatically by the header tank feeding
the system.
