3.3 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
e following checks and maintenance should be
performed at least 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 combustion chamber. It is also forbidden to use alkaline
or acid detergents.
- Check the integrity of the insulating panels inside the com-
bustion chamber and if damaged replace them.
- Visually check for water leaks or oxidation from/on con-
nections and traces of condensate residues inside the sealed
chamber.
- Check the contents of the condensate drain trap.
- 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 con-
sequent 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
aer relling the system by means of the lling valve) is be-
tween 1 and 1.2 bar.
- Check visually that the safety and control devices have not
been tampered with and/or shorted, in particular:
- Check the condition and integrity of the electrical 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.
- Check the CO
2
by using the chimney sweep func-
tion at the three reference heat outputs, using the
parameters in the table below. Should values out of
the indicated tolerance range be detected, check the
integrity of the ignition / detection electrode and, if
required, change it, also changing the relative gasket.
At this point, activate the “complete calibration”
function.
- Check correct operation of control and adjustment
devices and in particular:
- system regulation probes intervention;
- domestic hot water control thermostat interven-
tion.
- Check sealing eciency of gas circuit and the inter-
nal system.
- Check the intervention of the device against no gas ionisation
ame control. Intervention time must be less than 10 seconds.

In addition to yearly maintenance, one must also
check the energy eciency of the thermal system,
with frequency and procedures that comply with the
indications of the technical regulations in force.
