Before the installation: Check the ionisation electrode
DANGER!
High voltage on the bare ionisation electrode.
Risk of death from contact.
Only allow qualified electricians to perform the electrode test.
Wear face protection and insulating protective gloves.
Switch off and secure additional aggregates, burners and gas valves.
Inertise the gas line completely.
Line breaks and earth short circuits can be determined with the electrode test. Testing princi-
ple: An existing flame is simulated by connecting an inspection diode.
An inspection diode is required for the electrode test: Item number: 646R0100
