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 , then ••
flashing briefly before displaying the ‘Standby’ symbol .
2. Press & together and hold for at least 6 seconds
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.

• 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 and symbols.
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 will
reappear in the display.
• The De-aeration function can be repeated as necessary
until all air is expelled from the system.

Gas Settings
7.4.1 Checking Combustion -
‘Chimney Sweep’ Mode
The case front panel must be fitted when checking combustion.
Ensure the system is cold & the gas supply turned on & purged.
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.
1. Press & together and hold for at least 6 seconds.

point (eg. , or ) flashing alternately.
Important:
There may be a
delay before the boiler fires.
2. To adjust the boiler input setting, press or button
and the current setting point will flash (eg. , or ). Press the
or button again to alter the boiler input setting.
= MAX. HEATING input, = MAX. DHW input,
= MIN. input
4. The combustion (CO level & CO/CO
2
ratio) must be measured
and recorded at MAXIMUM DHW input & MINIMUM input.
5. Follow the flow chart on the next page to comply with the
requirement to check combustion on commissioning.
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.
6. Press & again for at least 6 seconds to exit.
7. Press the once to bring the boiler out of ‘Standby’ mode.
8. Use the button to toggle through the CH and DHW
settings to activate the required modes.
