3 Prepare for operation
3.1 Sealed heating system
Appliances that can be connected to sealed heating systems are pre-
pressurised before operation, this pressure must be maintained for safe
use of the appliance.
▶ Check regularly that the pressure is maintained.
▶ Re-charge the system if the pressure indicator reads less than 0.8
bar.
▶ If a permanent significant decrease or increase in pressure is shown
on the pressure indicator, contact your installer or maintenance
engineer.
Pressure indicator
▶ Type of pressure indicator for the system pressure.
– Pressure gauge (an analogue dial showing the pressure)
– Pressure menu (a digital readout of the pressure)
▶ Your appliance may have one or both types of methods to indicate the
system pressure. The type of method used on this appliance will be
detailed in the following section.
3.1.1 Checking the system pressure
Your installer will advise you of the optimum operating pressure.
▶ Check the system pressure on the pressure gauge.
–Static pressure is when appliance is cold and has not fired for
heating or hot water. This will generally be 1 - 1.5 bar.
–Operating pressure is when the appliance is firing for a heating
or hot water demand. This will generally be 1 - 2 bar.
▶ Top up the heating water, if the pressure is too low.

▶ Press the ok key.
The actual pressure appears.
3.1.2 Low pressure indication
Low pressure (shaded area [A]) will be indicated on the appliance:
• The needle is within the area between 0 and 1bar.

3.1.3 Constantly re-pressurising the system
Constantly having to re-pressurise the heating system should be
investigated as it is an indicator of potential leaks and the concentration
of inhibitor protection in the system will be reduced; this can result in
corrosion within the heating system, reducing efficiency and increasing
contaminates.
▶ Check for leaks on heating system (pipework and radiator valves).
▶ Contact your installer or maintenance engineer if a recurring
significant decrease or increase in pressure is shown on the pressure
indicator (pressure gauge or pressure display).
System pressure increasing:
▶ If the system pressure repeatedly increases and you need to vent air
from the radiators, refer to section "System gassing", page 17.
