Heating system pressure
From time to time you may need to top up the heating
system pressure. This 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 Commissioning Section - Filling the hot water and
heating circuits).
If the pressure falls below 1 bar, the boiler water
pressure switch will turn the boiler off until pressure is
restored.
To re-pressurise, the system needs to be topped up with
water.
First, switch the boiler OFF on the ON / OFF switch and
isolate the external electrical supply. Then remove the
casing top front panel by pulling it forward. The filling
valves “A” and “B” can now be seen. Open both valves and
allow the system to fill. When the combined temperature
and pressure gauge shows the required pressure, close
bothvalves. Replace the casing top front panel. Restore
the power supply and switch the boiler on.
Safety Valves
If water discharges from any of the safety valves, switch
the boiler off and call a service engineer.
