Regular boiler (iR-Range)
This boiler is part of an 'Open Vent' heating system. The system is not pressurized, but is
filled automatically by a filling system in the loft.
If there is a problem with this system, please contact your installer.
When the heating system is filled and after a power interruption the boiler will be reset
and starts with a air purge program. The automatic air purge program will take approx. 7
minutes and will be followed by the home screen if the water pressure is above 0.8 bar
(pressure reading for iC & iS boilers only).
