Ignitionelectrode

Replace the ignition electrode when necessary, but certainly every 4 years.

This can be checked by reading out the ionisation current. The minimum ionisation cur-

rent has be greater than 2,0 µA at full capacity.

To read out the ionisation 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 ionisation currunt 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.

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. 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.
