FUNCTION INTERRUPTION
• If the De-aeration is interrupted due to a fault the pump will
cease to circulate but the function timer (approx.10 minutes)
will continue to run. For this reason it is recommended to
monitor the boiler display during De-aeration. If the fault
cannot be rectified quickly the function must be restarted to
ensure complete De-aeration.
• In the event of a loss of power the De-aeration function
needs to be restarted once the power is re-established.
• In the event of low water pressure the fault code E118 will
be displayed, along with the flashing
This error can be rectified by repressurising the system to at
least 1.0 bar. The pump will restart automatically once the
water pressure is successfully re-established and
reappear in the display.
• The De-aeration function can be repeated as necessary
until all air is expelled from the system.

Commissioning Procedure

7.3.1

De-Aeration Function

The display backlight remains lit approx. 10 minutes. If
the backlight goes out during commissioning it does not
mean that the process has been completed.
This procedure MUST be carried out !
1. Ensure the gas is turned Off! Turn the power to the boiler ON.
The software version will be displayed, followed by
flashing briefly before displaying the 'Standby' symbol
2. Press
until is briefly displayed followed by
3. The De-Aeration Function is now activated. The boiler pump
will run for approx. 10 minutes. During this time the pump will
alternate on and off and the diverter valve will switch between
heating & hot water to purge air from the system.
4. At the end of the process the boiler will return to the 'Standby'
position.

The person carrying out a combustion measurement should
have been assessed as competent in the use of a flue gas analyser
and the interpretation of the results. See Section 10.1.3.
Important: Allow the combustion to stabilise before inserting the
Combustion Analyser Probe into the Test Point. This will prevent
saturation of the analyser.

The system MUST be cold to ensure the boiler is operating
under full demand. To obtain an accurate measurement on
smaller capacity systems it may be necessary to open one
or more hot taps and remove the diverter valve motor in
order to maintain the boiler output.
