and at minimum (Lo) power. From that
moment, the boiler will start working in
heating mode at maximum power, with cut
off at 80°C and re-ignition at 70°C.
Before activating the chimney sweep func-
tion make sure that the radiator valves or
eventual zone valves are open.
The test can also be carried out with the
boiler working in D.H.W. mode.
For this, after activating the chimney sweep
function, open one or more hot water fau-
cets. Under these conditions, the boiler will
function at maximum power with the
D.H.W. kept at between 60°C and 50°C.
During the test, the hot water faucets
must remain open.
For exit to the chimney sweep function
press the key
of the control panel.
The chimney sweep function will automa-
tically switch off after 15 minutes from
the activation.

FUNCTIONING ANOMALIES
When there is a functioning anomaly, an
alarm appears on the display and switch
on the red led.
Descriptions of the anomalies with relative
alarms and solutions are given below:
– FUMES DISCHARGE
ANOMALY "AL 01"
The fumes thermostat has intervened. If
the condition causing the problem persi-
sts for two minutes, the boiler stops for
an enforced period of thirty minutes.
SMOKE CHAMBER
CAMERA FUMO
MANICHETTA
SLEEVE
At the end of this period, the boiler re-
attempts ignition.
– LOW WATER PRESSURE
ANOMALY "AL 02" (fig. 22/a)
If the pressure detected by the water
pressure valve is lower than 0.5 bar, the
boiler stops and the display shows the
alarm "AL 02".

Bring the pressure back to normal by
specific valve until the pressure indicated
on the hydrometer reaches 1 - 1.2 bar.
ONCE IT HAS BEEN FILLED, CLOSE THE
LOADING VALVE.
If the load procedure has to be repeated
several times, it is advisable to check
that the seal of the heating circuit is
intact (check that there are no leaks).
