3.24 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
e following checks and maintenance should
be performed at least once a year.
- Clean the ue side of the heat exchanger.
- Clean the main burner.
- Check the correct positioning, integrity and
cleanliness of the detection and ignition elec-
trodes; 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 combustion chamber.
- Check the integrity of the insulating panels
inside the combustion chamber and if damaged
replace them.
- Visually check for water leaks or oxidation
from/on connections and traces of condensate
residues inside the sealed chamber.
- Check the contents of the condensate drain
trap.
- Via the condensate drain cap check that there
are no residues of material that clog condensate
passage; also check that the entire condensate
drainage circuit is free and ecient.
In the event of obstructions (dirt, sediment,
etc.) with consequent leakage of condensate
in the combustion chamber, one must replace
the insulating panels.
- Check that the burner seal gaskets and the lid
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, aer discharging the system pressure
and bringing it to zero (read on indoor unit
pressure gauge), that the expansion vessel
charge is at 1.0 bar.
- Check that the domestic hot water expansion
vessel charge is at a pressure between 3 and 3.5
bar.
- Check that the system static pressure (with
system cold and aer 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 Magne-
sium Anode (if present).
- Check the condition and integrity of the elec-
trical system and in particular:
- electrical power cables must be inside the
fairleads;
- there must be no traces of blackening or
burning.
- Check correct lighting and operation.
- Ensure correct calibration of the burner in
domestic water and heating phases.
- Check correct operation of control and adjust-
ment devices and in particular:
- system control thermostat intervention;
- domestic hot water control thermostat inter-
vention.
- Check sealing eciency of gas circuit and the
internal system.
Values Te1 and Te2 are determined by the logic of the product board
(Setting the manual mode "I 05" = "MA" the "Te1" value matches "I 06" and the "Te2"
value corresponds to "I 06" + 5 °C)
- Check the intervention of the device against no
gas ionisation ame control. Intervention time
must be less than 10 seconds.
N.B.: in addition to yearly maintenance, one
must also check the thermal system, with fre-
quency and procedures that comply with the
indications of the technical regulations in force.
