9.7 Check and replacing
ionisation electrode
The ionisation electrode must always be in contact with the flame. During burner
operation, the measured ionisation flow must following data display:
- At minimum power > 5 µA DC (switching threshold at 0.7 µA DC)
- At maximum power > 10 µA DC
Measurement ionization current
For measurement of the ionisation current, pull plug from the gas-firing autom-
aton and connect amperemeter between plug and electrode.
Danger of electric shock!
Do not touch plug contacts during the ignition process!
Changing the ionisation electrode
Danger of electric shock!
Before performing service work, power to the boiler must
be shut off and it must be secured from accidentally being switched back on!
