3.20 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
The following checks and maintenance should
be performed at least once a year.
- Check that the system's water PH is between
6.5 and 8.5.
- Visually check for water leaks or oxidation
from/on fittings and traces of condensate
residues inside the sealed chamber.
- Check contents of the condensate drain trap.
- Check that there are no residues of material
clogging the condensate passage; also check
that the entire condensate drainage circuit is
clear and efficient.
- Visually check that the water safety drain valve
is not clogged.
- Check that, after discharging 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 after refilling the system by
means of the filling valve) is between 1 and 1.2
bar.
- Visually check that the safety and control
devices have not been tampered with and/or
short-circuited.
- Check the condition and integrity of the electri-
cal system and in particular:
- supply voltage cables must be inside the
fairleads;
- there must be no traces of blackening or
burning.
- Check ignition and operation.
- Check correct calibration of the burner in
domestic hot water and central heating phases.
- Check the operation of the appliance control
and adjustment devices and in particular:
- system regulation probes intervention;
- the intervention of the DHW adjustment
thermostat
(when the boiler is connected to
an external storage tank unit)
.
- Check sealing efficiency of the gas circuit and
the internal system.
- Verify the intervention of the ionisation flame
control no gas device:
- Check the CO
2
by using the chimney sweep
function at the three reference heat outputs
and using the parameters in Fig. 3-14. 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.
- Carry out the flue test. Values below 40%
compared to the pressures detected upon first
check, suggest a clogged burner or module (flue
side).
Attention:
the burner does not need to be
opened for normal maintenance of the appli-
ance. However, should it be removed, you must
change the gasket.
IMPORTANT NOTE:
in addition to yearly
maintenance, you must also check the thermal
system and energy efficiency, with the frequency
and procedures that comply with the technical
regulations in force.
