MAINTENANCE
Carry out the following operations at the end of the heating season:
• Clean air dampers, the air pressure switch with pressure port and
the relevant pipe, if any.
• Check the electrode condition. Replace them, if necessary.
• Clean the photocell. Replace it, if necessary.
•
Have the burner and the chimney cleaned by specialised personnel
(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 con
-
dition, have not been deformed and are free from deposits deriving
from the installation environment and/or from poor combustion.
•
Analyse combustion gases and check emissions values.
If the combustion head needs to be cleaned, remove the components
following the procedure indicated below:
• Remove the UV photocell.
• Disconnect the connectors of solenoid valves, the fuel servomotor
and the pressure regulator.
•
unscrew the anchoring screws (12), and open the ventilating body;
•
pull out the ignition cables (14) from their electrode terminals (13);
• Unscrew the caps (22), on one of which the pressure gauge indi-
cating the pressure in the return circuit is installed, to enable the
draining of the residual diesel still present in the atomization unit.
Disconnect the unit connection pipes, unscrewing the nuts (19).
•
unscrew the screw (8) from the buffer (17)
•
Pull out the entire mixer unit in the direction shown by the arrow.
When you have finished maintenance work, proceed to reassemble
the combustion head, following the same procedure in reverse, after
checking the correct position of the ignition electrodes.
