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 cur-
rent 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
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 (refer to fig. 13.3.c and i)
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.
