Heating System Pressure
From time to time you may need to top up the heating circuit
water level to get the required pressure in the system. The
circuit pressure is indicated by the combined temperature
and pressure gauge on the boiler control panel.
The minimum pressure when the boiler is cold should be 1
bar. The precise operating pressure required depends on the
height of the building and your installer will have informed
you of this value at the time of installation (see Starting up
section - Filling the DHW and heating circuits).
If the pressure falls below 1 bar, the boiler water pressure
switch will turn the boiler off until the pressure is restored
To restore the pressure, top up the heating circuit with water
by opening the filling valve (A) of the boiler primary circuit
and allow the system to fill. Once the pressure gauge of the
boiler control panel indicates the required pressure, close the
filling valve.
Safety valves
If water discharges from any of the safety valves, turn the boiler off and
call a service engineer.
