Danger of electric shock

Danger to life due to electric current!

Before service work is started, the boiler has to be de-energised 

and secured from accidentally being switched back on.

The following steps describe how to change the ignition electrodes:

1. Loosen ignition cable

2. Loosen nuts and pull the ignition electrode block with seal out of the 

burner cover 

Note

The illustration shows removal of the ignition electrodes from the 

EC four 125 kW - 170 kW. Removal of the ignition electrodes from 

the EC four 215 kW - 300 kW is carried out in the same way.

3. Insert the new ignition electrode block with seal and fasten with nuts 

Note

Please note: The spacing and installation positions specified in the 

section 

Electrode spacing and installation locations

 must be hee­

ded.

4. Reconnect the ignition cable 

For more information, see

Electrode spacing and installation locations, page 137

10.3.9 Checking the ionization electrode

For measurement of the ionization current, pull plug from the gas burner 

control and connect ammeter between plug and electrode. Measurement 

must be carried out at full load and part load.

Danger of electric shock

Danger to life due to electric current! 

Do not touch plug contacts during the ignition process!

The ionization electrode must always be in contact with the flame. During 

burner operation, the measured ionization flow must display the following 

values:

at minimum power > 5 µA DC (switching threshold at 0.7 µA DC)

at maximum power > 10 µA DC

If these values are not reached, the ionization electrode must be replaced.
