MAINTENANCE
The burner does not require special maintenance, but it is good practice to check periodically that the gas filter is clean and that the ionisation
electrode is efficient. It is also necessary to verify that the ignition electrode's spark is produced between the same electrode and the disk.
The combustion head may need cleaning. During re-assembly, special attention must be paid to centring exactly the electrodes (ignition
and flame detection) in order to avoid them going to earth, which would result in the "lock-out" of the burner. The majority of the components
can be checked removing the casing. To check the head, disassemble the mixing unit following the instructions below.
1) Undo the lid screw "A" to gain access to the interior of the
burner.

2) After disconnecting the gas train, unscrew the 3 screws "B" that
fasten the flange of the gas delivery fitting to the burner plate.
3) Remove the mixing unit in the figure.
