3.11 "CHIMNEY SWEEP" FUNCTION.
This function allows the technician to check
the combustion parameters. Boiler operation in
chimney sweep function can be adjusted to an
output between 0% and 100%.
To enable the function press and hold down “A”
The output is adjusted from the + and - DHW
adjustment buttons at a range between 0 and
100%, while using the + and - buttons for CH
adjustment, the percentage changes by 1% each
time they are pressed.
In this state all adjustments are excluded and only
the temperature safety thermostat and the limit
thermostat remain active. When the checks are
finished, disable the function by pressing and
holding down button “A”.
If you enable the function when there is no active
request, you will need to wait approximately 30’’
to reach the set output. If you enable the function
when there is an active request, you will need
to wait approximately 3 minutes to reach the
set output.
3.12 3-WAY PUMP ANTI-BLOCK
FUNCTION (OPTIONAL).
The boiler has a function that starts the pump
and 3-way valve at least once every 24 hours for
the duration of 20 seconds in order to reduce
the risk of the pump becoming blocked due to
prolonged inactivity.
3.13 RADIATORS ANTI-FREEZE
FUNCTION.
The boiler has a function that makes the pump
start when the system flow water reaches 8 °C. If
the system flow water is at a temperature below
5 °C, the boiler starts to operate until it reaches
approximately 16 °C.
3.14 ANTI-HUMIDITY ELECTRODE
FUNCTION.
With cascade installations combined with their
relative flue manifold kits with flue adjusting
devices, humidity may develop on the electrodes,
causing them to fail. Avoid the formation of
humidity by enabling this function (by setting
a value other than 0), which turns the fan on
at the speed set in parameter “P11” (5 minutes
on and 5 minutes off). The function is active
when the burner is off and the flow NTC probe
temperature reading is greater than 35°C. The
function is disabled when the temperature drops
below 30 °C.

3.15 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.
