IGNITION – IONIZATION ELECTRODE
Subject
Description
Part Function
1- To ignite and start burning the gas-air mixture coming from the
burner.
2- To detect whether flame is formed in the burner.
Impact in Case of
Faulty Operation
1- No ignition and burning as result of that the distance between
electrode ends is too much or too narrow
2- Noisy burning (explosion burning) as result of late ignition
3- Due to electrode being away from the burner, reduced ionization
flow and flame loss in boiler time to time
Primary Relevant
Error Codes
E01, E82
Troubleshooting and
Testing Method
1-Visual inspection: If there is any oxidation, etc. on electrode rods, it
must be cleaned with a cloth.
2- Electrode dimensional measurement controls
3- Ionization flow control
4- Replace electrode and electrode gasket together
Maintenance Period
Once a year or in any erros due to electrode, according to instruction
written above. The electrode gasket must be replaced after each
dismounting operation.

Maintenance Method
Electrode Measurement
Controls
A) Distance between electrode rods must be in the range of 9.5-
10.5 mm.
B) Measure the distance between two ends of electrode; it must
be in the range of 3.5-4.5 mm.
C) The closest distance of electrode rod to the burner must be in
the range of 6,5-8,5 mm.
Testing Definition
Testing and Maintenance Method
Ionization Current Control
After starting, access to Inquiry mode "In".
Access to i09 inquiry parameter. Wait at this parameter for 2
minutes and check whether ionization flow is at least “
25
” or over
on LCD screen.
