9. Hydraulic data The boiler is fitted with an automatic by-pass as standard. The graphs (Fig. 10) show the development of the pressure available in relation to flow (on exit from the boiler). To ensure correct operation, the minimum flow of the appliance must be 300 l/h. (Thermostatic taps closed). Capacity of the installation. The water heater is fitted with a pressurised expansion vessel. Maximum volume of expansion vessel: 6 litres. Pressure: 1 bar. The volume of the expansion vessel in a pressurised appliance varies according to: - the average operating temperature in °C - the static height, which is the difference in metres between the highest point of the appliance and the expansion vessel axis. The minimum cold filling pressure of the appliance is 0.8 bar (recommended pressure between 1.0 and 1.5 bar). The pressure of the expansion vessel should always be greater than the static height (in metres) divided by 10.
