MAINTENANCE
Analyse combustion gases and check that the emission values
are correct at least once a year, in compliance with current law.
Carry out the following operations at the end of the heating sea-
son:
• Clean air dampers, the air pressure switch with pressure port
and the relevant pipe (if fitted).
• Check the electrode condition. Replace them, if necessary.
• Clean the photocell. Replace it, if necessary.
• Have the burner and the chimney cleaned by specialised per-
sonnel (stove repairer); a clean burner is more efficient, lasts
longer and is quieter.
• Check that the fuel filter is clean. Replace it, if necessary.
• Check that all components of the combustion head are in good
condition, have not been deformed and are free from deposi-
ts deriving from the installation environment and/or from poor
combustion.
• Analyse combustion gases and check emissions values.
DANGER / CAUTION
When closing the burner, gently pull the two ignition cables
towards the electrical panel, putting them slightly in tension,
then arrange them in their housing on the scroll. This will
ensure that the two cables do not get damaged by the fan
during burner operation.
If it is necessary to clean the outside of the combustion head, take
out its components according to the procedure described:
• Disconnect the photocell and the air pressure switch pipe from
the upper lid of the burner.
• Disconnect diesel fuel pipe -24 from its connector (be careful
of drips).
• Loosen screws 5 -6 and remove the cover -11 .
• After having loosened the nut -9 remove the locking screw (32)
of the mixer unit.
• Remove the screw -16 and its washer placed on the outside of
the burner scroll.
• Slightly lift the mixing unit -17, and then completely pull out the
unit in the direction indicated by the arrow, after removing the
ignition cables -10 from the respective electrodes.
• After completing the maintenance operations proceed with the
assembly of the mixing unit by carrying out the above opera-
tions in reverse order, after checking that the ignition electrodes
and the deflector disk are correctly positioned.
