– loosen the clips (6) and extract the air inlet pipe (7)
– unscrew the swivel joint (8)
– extract the connectors (9) from the fan and disconnect the
electrode cable (10)

CAUTION
Work carefully when removing the assembly (13) to
prevent any damage occurring to the internal insulation
of the combustion chamber and the door seal.

4.3.2
The combustion chamber and the burner do not require any
particular maintenance. Simply brush them with a soft brush.
4.3.3
Check the state of the ignition/detection electrode and replace
if necessary. Check the measurements as per the drawing
whether the ignition/detection electrode is replaced or not.

4.3.4
After having cleaned the combustion chamber and the burner:
– remove any carbon residue
– check that the seal and the insulation of the door (12) to the
combustion chamber are integral. Replace if necessary
– refit the assembly by carrying out the same operations for
removal but in the reverse order and tighten the screws (11)
of the door to the combustion chamber
– reconnect the connections to the fan and the electrode.

4.4.1
It is recommended that the user checks that the combustion air

inlet duct and smoke outlet duct are integral and airtight.
4.4.2
The wear of the magnesium anode must be checked once a year .
To do this:
– empty the tank as described under EMPTYING operations
– unscrew the anode, remove and check for wear
– refit the anode or, if necessary, replace.
4.4.3
It is recommended that the expansion vessel on the water side
is drained and that the prefilling pressure is not less than 1 bar .
If this is not the case, pressurize it to the correct value (see
sectionExpansion vessel".
Once the checks described above have been completed:
– refill the boiler as described in section "REFILL operations".
The tank MUST be filled and emptied at least twice to avoid
bacterial contamination
– check that the siphon has been filled correctly
– check that there are no leaks from the magnesium anode
– Start the boiler, activate the "Chimney sweeper function" and
11
carry out a smoke analysis and/or measure the combustion
efficiency
– refit the front panel securing it with the two screws which
were removed previously.
