Part’s Function
1
-
Ignites the gas+air mixture from the burner and starts combustion.
2- Detect if there is flame in the burner.
Impact in Case of Malfunction
1- There may be no ignition or combustion due to excessively increased or decreased
distance between the ends of the electrode.
2- The device may produce noise while burning due to delayed ignition (back flash).
3- The ionization current may be reduced due to the electrode moving away from the
burner and there may be flame
loss in the boiler at certain times.
Main Associated Error
Codes
E01, E82
Error Diagnostics-Test Method
and Maintenance
1- Visual Inspection: Remove any oxidization, etc. on the electrode rods using a piece of
cloth.
2- Check the electrode measurements.
3- Check the ionization current.

Test and Maintenance Method
Electrode Measurement Checks
A) The spacing between the electrode rods should be 9.5 -10.5 mm.
B) Measure the distance between the two ends of the electrode. It should be in the
3.5 - 4.5 mm range.
C) The closest distance between the electrode rod and the burner should be in the
6.5 - 8.5 mm range.

Test and Maintenance Method
Ionization Current Check
Turn on the combi boiler. After tu rning the device on, enter the Information mode "In”.
Enter the I09 information parameter. Wait this parameter for 2 minutes and ensure that the
ionization current reading on the LCD screen is at least "40" or above.
