Instructions general
A pressure reducing valve must be fitted to the cold water inlet if the incoming water pressure
exceeds 400 KPA (4.0 Bar).
The primary operating pressure initial charge is 120 KPA (1.2Bar) this will increase to around 200
KPA (2.0Bar) when the system has reached maximum temperature and will depend on system
volume.
The primary expansion vessel pre-charge pressure is 150 KPA (1.5 Bar) and has volume of 25 and
35 litres depending on the model of boiler.
The secondary expansion vessel pre-charge pressure is 350 KPA (1.0 Bar) and has a volume of
1litre.
The primary pressure relief valve is set to 300 KPA (3.0 Bar).
