MAINTENANCE
The burner does not require any particular maintenance, it is
recommended at least to 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.
•
Clean the photocell.
•
If necessary, have the burner and the chimney cleaned by
specialized personnel (stove repairer); a clean burner is more
efficient, lasts longer and is quieter.
•
Periodically check that the gas filter is clean for gas burners.
•
In order to clean the combustion head, its components
must be disassembled. Be careful during the reassembly
operations to exactly centre the gas diffuser with
regard to the electrodes, making sure that they are not
earthed, which would result in the locking of the burner.
After regulating the two electrodes as described at diagram
0002937182. Make sure that the ignition spark occurs only
between the two electrode ends.
•
Analyse combustion gases and check emissions values.
•
Check that all components of the combustion head are in good
condition, have not been deformed by high temperatures and
are free from impurities or deposits deriving from the installation
environment or from poor combustion. If it is necessary to clean
the combustion head, take out its components according to the
procedure described below:
- remove the UV photocell
- Disconnect the connectors of gas and diesel solenoid valves,
the gas servomotor and of the pressure regulator.
- unscrew the anchoring screws (N), and open the ventilating
body;
- pull out the ignition cables (I) from their ignition electrode
terminals (L);
- Unscrew the caps (O), on one of which the pressure gauge
indicating 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 (M) of the "T" -shaped unions.
- Loosen the nut (A) and the pawl (B), turn the rod (C) to
unscrew it from the piston (D), then remove it completely
from the burner body.
- Unscrew the screw (R) and the screw (S) from the lung (P);
- 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 (0002937182стр. 19).
