MAINTENANCE
Analyse combustion gases and check that the emission values are
correct at least once a year, in compliance with current law.
• Clean air dampers, the air pressure switch with pressure port and
the relevant pipe (if fitted).
• 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.
• In order to clean the combustion head, its outlet and components
must be disassembled. Be careful during the reassembly operations
to exactly centre the gas diffuser with respect to the electrodes,
making sure that they are not earthed, which would result in the
locking of the burner. Verify also that the ignition electrode spark
takes place exclusively between itself and the perforated sheet
metal disk (see combustion head and electrode disk distance
regulation diagram) for the version without pilot.
• Analyse combustion gases and check emissions values.
• Check that all components of the combustion head are in good
condition, have not been deformed and are free from deposits
deriving from the installation environment and/or from poor
combustion.
If it is necessary to clean the outside of the combustion head, take out
its components according to the procedure described:
• Remove the UV photocell.
