3.23 YEARLY APPLIANCE CHECK AND
MAINTENANCE.
The following checks and maintenance should
be performed at least once a year.
- Clean the flue side of the heat exchanger.
- Clean the main burner.
- If deposits are detected in the combustion
chamber one must remove them and clean
the exchanger coils using nylon or sorghum
brushes; it is forbidden to use brushes made
of metal or other materials that may damage
the combustion chamber itself.
- 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 fittings and traces of condensate
residues inside the sealed chamber.
- Check 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 clear and efficient.
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 efficient, 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
fixed to the combustion chamber lid; otherwise
it must be replaced.
- Visually check that the water safety drain valve
is not clogged.
- Check that the system static pressure (with
system cold and after refilling the system by
means of the filler cock) is not below 0.5 bar.
- Visually check that the safety and control
devices have not been tampered with and/or
shorted, in particular:
- temperature safety thermostat;
- 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 ignition and operation.
- Check correct calibration of the burner in
central heating phase.
- Check the operation of the appliance control
and adjustment devices and in particular:
- intervention of the main electrical switch on
the boiler;
- system regulation probes intervention;
- Check sealing efficiency of the gas circuit and
the internal system.
- Check the intervention of the device against
no gas ionisation flame control. The relative
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.
