1.3 System Pressure – System & Combination Boilers
When the boiler is connected to a sealed system the system pressure should be
periodically checked using the pressure gauge (1), located above the expansion
vessel.
System Boilers
Combination Boilers
The system pressure as indicated by the black needle, is minimum 1.0 bar when
the boiler is cold and up to 2.5 bar when the boiler is at normal operating
temperature.
If the system pressure falls below the minimum (e.g. due to the removal of a
radiator for decorating purposes) then the system should be topped up using the
filling loop. See Section 1.4.
Frequent or routine topping up of the system should not be necessary and
may prove harmful to the appliance. Should topping up prove necessary on
a frequent or routine basis you must contact Warmflow or your installer.
Special attention must be given to corrosion inhibitor concentrations where
there is a need to top up the system. See Section 1.5.
A pressure sensor is included as standard on all Combination boiler models which
prevents the operation of the boiler if the system pressure drops below 0.4 bar,
this will be indicated by code E04 on the LCD.
The indication of the system pressure on the gauge and on the LCD have a
tolerance of +/-0.2 bar at idle state.
Do not allow the flexible hoses connected to the expansion vessel to
become twisted, kinked or flattened. This may cause collapse of hose bore
compromising the function of the expansion vessel.
