4. Check the CO2 percentage on the flue gas analyzer. The percentage must be 9.0% (+/– 0.3%) for natural
gas. For LPG it must be set to 10.0% (+/-0.3%)
a.) In case the CO2 value is not within tolerance, the value must be adjusted. By pressing [P3] or [P4] the
flame impedance is shown. Use [P3] for increasing the CO2 value. Use [P4] for decreasing the CO2
value.
b.) When the CO2 value is within tolerance confirm with [P2].
5. The fan adjusts to start speed.
- CO2 setting natural gas 9.0% (+/– 0.3%)
- CO2 setting LPG 10.5% (+/-0.3%)
a.) repeat step 4.
6. The appliance goes to the third and last step (Modulation is 0%).
- CO2 setting natural gas 9.0% (+/– 0.3%)
- CO2 setting LPG 10.0% (+/-0.3%)
a.) repeat step 4.
Automatic calibration
The automatic calibration function enables you to calibrate the boiler without analyser to make sure that the
EcoKing burns safely without producing CO. This function performs the same procedure as the manual
calibration, but here the flame impedance values go to pre-set values from the data key.
1. Simultaneously press [P1] and [P3] for 5 seconds until the text ’test’ appears in the display.
• The ’ladder’ symbol flashes in the display.
• The fan speed (rpm) increases until the start speed is reached. The display shows the speed of the fan.
• The capacity of 100% flashes on the right in the display. 1 and 00 appear alternately in the display.
• The starter current is determined and the boiler ignites. The ’flame’ symbol and the text ‘ok’ appear when the
flame is stable.
• When the speed and the CO2 percentage for the starter capacity of 100% is stable, the boiler will set the
CO2 percentages at the fan capacities for ignition and 0%.
• When this procedure is completed, the boiler goes to the default menu and is ready for use.
Warning
The CO2 percentages for the minimum and maximum load must be checked in the service menu at installer level.
Warning
Recalibrate after a software update
When the appliance has been provided with updated software, always:
1 Recalibrate the start current.
2 Check the flame impedance values.
3 Perform the Manual or Automatic calibration procedure.
Service operation
1. Press [P1] and [P2] simultaneously to access the service menu at installer level.
2. Put the figure on the left side of the display to ’08’ with [P3] or [P4].
3. Confirm with [P2].
4. Press [P1] and [P2] simultaneously for 5 seconds. The boiler starts in service mode. ‘Test’ appears on
the display at the left down corner.
5. Use [P3] to set the appliance to minimum power.
6. Use [P4] to set the appliance to maximum power.
