Maintenance details
Ignition electrode
Replace the ignition electrode when
necessary, but certainly every 4 years.
This can be checked by reading out
the ionization current. The minimum
ionization current has be greater than
2,0 µA at full capacity.
To read out the ionization current follow
the instructions:
From the standard blue screen display:
1. Press down the arrow buttons
simultaneously for 2 seconds;
2. Continue with point 3.
From the setting level with a green
screen:
3. Select using the right arrow button:
Info;
4. Press the OK button;
5. Press the right arrow button until:
Burners
Flame
0.00 uA
6. Press the OK button;
7. Press the right arrow button until:
Flame.
The ionization current is shown
here in µA. With the + and - button
the value of burner A and B can
be shown (heat exchanger symbol
turns from A to B).
If the sight glass is damaged, the
complete ignition electrode has to be
replaced.
Replace as follows:
- Remove the plug connections of
ignition electrode;
- Push the clips on either side of the
electrode to the outside and remove
the electrode;
- Remove and replace the gasket;
Assembly is done in reverse order.

Condensate container
Take precautions to prevent
condensate falling on electronics
and other boiler parts during
dismantling to avoid damage of
these parts.
- Remove the short clamping bars (7
and 8) by loosening them a quarter
of a turn with the hex key. In doing
so, pay attention to the turning
direction (red check cams).
- Pull the clamping bars forward
and away from underneath the
condensate container.
- Carefully push the condensate
container (12) down and remove it
from the front;
- Replace the condensate container
gasket by a new one.
- Clean the polluted condensate
container with water and a hard
brush.
- Check the condensate container for
any leakages.
Assembly is done in reverse order.
Ensure proper all around sealing of the
gasket when installing the condensate
container.
Ensure during assembly that
the clamping bars are properly
positioned. They have to be in a
vertical position.
During maintenance always replace
the gaskets of dismantled parts.
