N.B.: the power data in the table has been
obtained with intake-exhaust pipe measuring 0.5
m in length. Gas ow rates refer to heating values
below a temperature of 15°C and at a pressure of
3.21 VARIABLE HEAT POWER.
3.20 YEARLY CONTROL AND
MAINTENANCE OF THE
APPLIANCE.
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.
- 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 connections 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 free and ecient.
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 ecient, 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 the system static pressure (with
system cold and aer relling the system by
means of the ller cock) is not below 0.5 bar.
- Check visually 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
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 correct calibration of the burner in
central heating phase.
- Check correct operation of control and
adjustment devices and in particular:
- intervention of main electrical switch on
boiler;
- system regulation probes intervention;
- Check sealing eciency of gas circuit and the
internal system.
- Check the intervention of the device against no
gas ionisation ame control. Intervention time
must be less than 10 seconds.
N.B.: on occasion of periodical maintenance of
the appliance it is appropriate also to check and
perform maintenance on the heating system, in
compliance with that indicated by the regulations
in force.
