Cleaning/replacing the electrodes
To clean/replace the electrodes, proceed as follows:
1 remove the combustion head as described in the previous paragraph;
2 remove the electrodes ass.y and clean them;
3 in order to replace the electrodes, unscrew the VE fixing screws and remove them: place the new electrodes being careful to
observe the measures in the previous paragraph; reassemble the electrodes and the combustion head following the reversed pro-
cedure.
Cleaning and replacing the detection photocell
The photocell working life is about 10000 working hours (about 1 year), at max 50°C after
which it must be replaced.
To clean/replace the detection photocell, proceed as follows:
1 Disconnect the system from the electrical power supply.
2 Shut off the fuel supply
3 remove the photocell from its slot (see next figure);
4 clean the bulbe if dirty, taking care not to touch it with bare hands;
5 if necessary, replace the bulb;
6 replace the photocell into its slot.
ATTENTION: avoid the electrodes to get in touch with metallic parts (blast tube, head, etc.), otherwise the boiler operation
would be compromised. Check the electrodes position after any intervention on the combustion head.
