3.3 YEARLY APPLIANCE CHECK AND
MAINTENANCE
e following checks and maintenance should be per-
formed once a year to ensure operation, safety and e-
ciency of the appliance over time.
- Clean the ue side of the heat exchanger.
- Clean the main burner.
- Check the correct positioning, integrity and cleanliness of the
detection and ignition electrode; remove any oxide present.
- If deposits are detected in the combustion chamber they must
be removed and the heat exchanger coils must be cleaned using
nylon or broomcorn brushes; it is forbidden to use brushes
made of metal or other materials that may damage the combus-
tion chamber. It is also forbidden to use alkaline or acid deter-
gents.
- Check the integrity of the insulating panels inside the combus-
tion chamber and if damaged replace them.
- Visually check for water leaks or oxidation from/on connec-
tions and traces of condensate residues inside the sealed cham-
ber.
- Check the contents of the condensate drain trap.
- Visually check that the siphon is properly lled with condensate
and top it up if necessary.
- Check that there are no material residues in the condensate
drain siphon clogging the condensate passage; also check that
the entire condensate drainage circuit is clear and ecient.
- In the event of obstructions (dirt, sediment, etc.) with conse-
quent leakage of condensate in the combustion chamber, one
must replace the insulating panels.
- Check that the burner and gas manifold seal gaskets are intact
and perfectly ecient, otherwise replace them. In any case the
gaskets must be replaced at least every two years, regardless of
their state of wear.
- Check that the burner is intact, that it has no deformations or
cuts and that it is properly xed to the combustion chamber lid;
otherwise it must be replaced.
- Visually check that the water safety drain valve is not blocked.
- Check that, aer discharging the system pressure and bringing
it to zero (read on boiler pressure gauge), the expansion vessel
pressure is at 1.0 bar.
- Check that the system static pressure (with system cold and af-
ter relling the system by means of the lling valve) is between 1
and 1.2 bar.
- Check visually that the safety and control devices have not been
tampered with and/or shorted, in particular:
- temperature safety thermostat;
- system pressure switch.
- Check the integrity of the storage tank magnesium anode (if
present).
- Check the condition and integrity of the electrical system and in
particular:
• the power supply wires must be housed in the cable glands;
• t h e r e m u s t b e n o t r a c e s o f b l a c k e n i n g o r b u r n i n g .
- Check correct lighting and operation.
- Ensure correct calibration of the burner in domestic water and
central heating phases.
- Check correct operation of control and adjustment devices and
in particular:
• system control thermostat intervention;
• domestic hot water control thermostat intervention.
- Check sealing eciency of gas circuit and the internal system.
- Check the intervention of the device against no gas ionisation

- Check chiller line connections.
- Check mesh lter on system return
- Check the correct ow rate on plate heat exchanger.
- Check the integrity of the internal insulation.
