Part 10 - Lighting the appliance / First start-up
Calibration
Before the first start up of the appliance (before calibration) check the gas type setting is set correctly (parameter 15,
page 49). The EcoKing boiler is gas-adaptive, which means that the combination ionisation electrode and the burner
pneumatically and electronically control the CO2 percentage. During calibration, the start current and the correct
settings for the CO2 percentage are determined. During the manual calibration the percentage can be adjusted if
necessary.
A: Flame impedance and temperature value
B: Ladder symbol: calibration menu
C: Flame symbol: ignition. The unit burns.
D: Speed (rpm/10)
E: Boiler capacity (%)
P2: ok | reset
P3: CH temperature down
Notice
The start current calibration starts automatically when the calibration is started.
Manual calibration
1. Start the system.
2. Connect the flue gas analyzer to the appliance. Two options for connection are available:
It is preferred to measure the flue gases with mounted front cover. To enable that use the access
/ sampling point in the M&G concentric vent system, just above the appliance.
Or in case this point would not be available;
Connection point for thermal fuse flue gas sensor. See figure 1.2 (D) for exact location. Remove
the thermal fuse sensor to obtain flue gas analyzer access.
Warning
Make sure the flue gas analyzer connection point is closed after performance of the calibration procedure by
replacing the thermal fuse / closing the sampling point in the M&G concentric vent system. Failure to do so may
result in serious injury or death.
Before starting calibration make sure the boiler can transport the produced energy into the system. Open en
enable all central heating circuits and / or create domestic hot water demand.
3. Simultaneously press [P2] and [P3] 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.
