7. Attention: High Voltage
For the measurement of the flame ionization and for the electrical ignition of the fuel very high voltages
that can be dangerous to life are generated in the device.
Never operate the device if the cover lid is not closed. Furthermore never touch anything inside the
device and never touch the ignition electrodes or the electrode cage while the device is switched on.
The electrode for the measurement of the flame ionization is energized while the fuel valves are
opened. A current limiting circuit in the device prevents that this can cause any danger.
8. Attention: Hot Surfaces
The following parts can heat up strongly during operation:
- the housing, especially the parts that form the burning chamber
- the electrode cage
- the ignition electrodes
- the electrode for the measurement of the ionization
Only touch these parts after they have cooled down sufficiently and the device is switched off.
