4.1 Open vented heating systems

If the boiler is fitted to an open vented system, that is a system with a header tank, the pressure will be maintained automatically.

4.2 Sealed heating systems

If this boiler is fitted to a sealed heating system, the system will be pre-pressurised.

Your installer will have fitted a pressure gauge and filling loop so that the system can be monitored and adjusted as necessary.

Your installer will show you how to use the filling loop and advise you of the minimum and maximum pressure indicated on the

pressure gauge.

▶ Check regularly that the pressure is maintained.

pressure gauge.

The filling method will be an external filling loop, fitted valves and flexible hose.

NOTICE: To comply with the Water Authority regulations you must disconnect the external filling loop after

re-pressurisation.
