Maintenance of the ionisation electrode
The detector electrode/ionisation probe play an important role in the boiler
ignition phase and maintaining an efficient combustion; in this regard, if it is
replaced, it must always be positioned correctly and the reference position
indicated in the figure must be complied with.

Do not sandpaper the electrode.
b
During the annual maintenance, check the state of wear of the
electrode and replace it if has badly deteriorated.
The removal and eventual replacement of the electrodes, including the
ignition electrode, involves also the replacement of the sealing gaskets.
In order to prevent operating faults, the detector electrode/ionisation probe
should be changed every 5 years since it is subject to wear during the
ignition.
Check valve (Fig. 22)
The boiler has a check valve.
To access the check valve:
- remove the fan by unscrewing the 4 screws (D) fixing it to the conveyor
- make sure there are no foreign material deposits on the membrane of the
check valve and if any remove them and checking for damage
- check the valve opens and closes correctly
- re-assemble the components in reverse order, making sure the check
valve is put back in the correct direction.
When there is maintenance work on the check valve make sure that it is
positioned correctly to ensure the system operates correctly and safely.
Removing the siphon (Fig. 23a-b-c-d)
- Switch off the electrical supply by turning the system's main switch to
"Off".
- Take out the condensate collection pipe (fig. 23a)
- Unscrew the SRD device (fig. 23b)
- Unscrew the screw (A) and remove the plate (B) as indicated in fig. 23c
- Take out the inside part (C) of the siphon as indicated in fig. 23d.
Once the operations are finished, put back the components in the reverse
order to that described, checking the gasket and sealing OR are correctly
positioned.
