3 CHECKING AND ADJUSTING CO

SETTING
3.1 Checking flue gas at maximum power.
1. Make sure that the appliance is switched off.
[-] is shown in the service display.
2. Remove the cap X of the flue gas sampling point on the adapter.
3. Position the measuring probe or the flue gas analyser into the sampling point.
Important
Ensure that the analyser start up procedure has been
finalized before placing the probe.
The probe needs to close the sampling point fully to ensure
an accurate measurement.
The end (tip) of the probe must be completely in the flue
gasses (in the middle of the flue pipe).
.
4. Switch the appliance on with the button.
5. Activate the test program for maximum output by simultaneously pressing the buttons
and twice.
A capital H appears in the service display.
Important
Make sure a capital H is shown in the display to ensure the
appliance to run at maximum power.
6. Wait until the reading of the flue gas analyser is stabilized (minimal 3 minutes).
7. Note the measured value : CO

Important
A deviation at maximum power can not be adjusted with the gas
valve setting. When the value measured at maximum power is
outside the prescribed range the boiler has to be checked on gas
tightness and usage of the correct components, in particular the
gas ring, the insert and the fan.
9. Proceed performing the measurement and adjustment on minimum output (see § 3.2).
3.2 Adjusting CO
2
value at minimum power
Important
Work on gas carrying parts may only be carried out by a qualified
competent person.
Before adjusting the CO
2
value at minimum output the measurement of the maximum
output must be completed. The measured O2 or CO2 value at maximum output is
important for determining the correct value for the measurement at minimum output.
See § 3.1 for measuring at maximum output.
