Pf = Cold pressure in bar
C = System capacity in litres
The boiler is fitted with an automatic by-pass as standard.
The graph (fig. 5) shows the development of the pressure
available in relation to flow (on exit from the boiler).
To ensure correct operation, the minimum flow of the
installation must be 300 l/h. (Thermostatic taps closed).
Capacity of the installation.
The boiler is fitted with an expansion vessel.
Maximum. volume of expansion vessel: 6 litres.
Pressure: 0,7 bar.
The volume of the expansion vessel in a pressurised
installation varies according to:
- the average operating temperature in °C
- the static height (which is the difference in metres
between the highest point of the installation and the
expansion vessel axis).
The minimum cold filling pressure of the installation is 0,7
bar (recommended pressure between 1.2 and 1.7 bar).
The pressure of the expansion vessel should always be
greater than the static height (in metres) divided by 10.
