Biopel MINI - Installation and Operation Instructions
39
Otherwise, the boiler will not be activated when you press Ignition.
The first start-up of the boiler is done. You can change most of the options again at any time after the First Start-up is complete
in the Main or Installation menus.
In the case of a non-standard installation with a different external feeder than
prescribed, a different chimney draft than prescribed, etc., we recommend that you
measure the external feeder power before starting the boiler, see the Combustion
Correction, Non-Standard Installations section.
When the boiler is activated by pressing Ignition in the unit menu, the pellets will ignite and the boiler will go into PID operation.
This is followed by Combustion Correction if the combustion process is not optimal, see the following chapter.
Therefore, the boiler's first start-up of the boiler is complete. Your selections have been saved in the operating memory of the
v9 MINI control unit. If you are unsure about any of the settings, you can perform the First Start-up again at any time in the
future. Keep in mind, however, that for proper memory storage, you must always perform the First Start-up in the deactivated
(extinction) state of the boiler, not in the Ignition or PID operation mode. After activating the Ignition, wait for the boiler to
ignite the pellets and enter into PID operation. The moment its power in PID operation is equal to 100%, you can start the
manual Combustion Correction. If you have connected and activated the Lambda probe, the Combustion Correction is
automatic. Continue with the combustion setting directly in the Installation menu, Lambda probe, according to the Lambda
probe manual. Always visually check the quality of the combustion process when correcting combustion.

COMBUSTION CORRECTION
After activating the boiler (Ignition), wait until the igniter ignites the pellets and the boiler goes into PID operation. In PID
operation, wait a few minutes until the main panel displays the maximum power in kW (set during First Start-up) and 100% fan
speed. At this point, the boiler is operating at full power. Open the ash door carefully and check the combustion quality, flame
parameters. In case they are not ideal, perform the correction as described below. We recommend checking the combustion
quality continuously, in case of a change in the chimney draft or the pellet type and quality, make the combustion adjustment
again. In case of installing Lambda probe, this correction is carried out automatically.
Caution: when the boiler is in operation and the flame is in the boiler, never open the front ash
door more than 2-3cm. There is a flame in the boiler and it would flare out of the boiler if opened
more. Always close the door after checking the flame so that no flue gas cannot escape into the
room.
10.1.
Flame quality
By checking the flame coming out of the burner, you can determine quite surely whether the combustion process is
optimal or whether a correction is necessary. Examples of good and bad combustion are given below.
Ideal flame at 100% power:
The maximum length depends on the burner type (may be affected by chimney draft and pellet type).
o
Boiler 10-15kW = approx. 25 - 30cm from the end of the grate
o
Boiler 20-30kW = approx. 35 - 45cm from the end of the grate
Yellow-orange colour, unburnt pellets do not fall from the grate, only fine ash in the ashtray.
Incorrect flame at 100% power:
Maximum flame length is less than or greater than the above.
Light yellow colour (too much combustion air) or dark orange to red (not enough combustion air).
Unburned pellets falling into the ashtray, dark smoke coming out of the chimney.
10.2.
Change fan speed
To change the fan speed at boiler min. and max. power, use the Fan Min. and Max. Coefficient function in the Installation
menu, Coefficients. Make the correction if the flame has the following parameters:
Downward correction (minus values):
Flame is too aggressive and spits.
Fan is dropping unburned pellets
Flame is small and aggressive
Upward correction (plus values):
Flame is slow and dark
The grate is clogged with black ash
