3.10 “CHIMNEY SWEEP” FUNCTION.

When activated, this function forces the boiler 

to variable output for 15 minutes.

In this state all adjustments are excluded and only 

the safety thermostat and the limit thermostat 

remain active. To activate the chimney sweep 

function, press the “Reset” button (5) event for 

activation in the absence of DHW requests.
Its activation is signalled by the indication of the 

flow temperature on the indicator(17), the power 

percentage on indicator (21) and switch-on of the 
relative symbol 

.

This function allows the technician to check the 

combustion parameters. 

Once the function is activated, it is possible to 

select whether to make the chick in CH status 

or DHW status by opening any hot water cock 

and regulating the power by turning the “CH 

regulation” selector (1).

Functioning in CH or DHW mode is displayed 
by the relative flashing 

 or 

symbols.

On completion of the checks, deactivate the 

function by pressing the “Reset” button (5) for 

8 seconds.

3.11 PUMP ANTI-BLOCK FUNCTION.

The boiler has a function that starts the pump 

once every 24 hours for the duration of 30 se-

conds in order to reduce the risk of the pump 

becoming blocked due to prolonged inactivity.

3.12 THREE-WAY ANTI-BLOCK 

FUNCTION.

The boiler is supplied with a function that ac-

tivates the motorises three-way unit every 24 

hours, carrying out a complete cycle in order 

to reduce the risk of three-way block due to 

prolonged inactivity.

3.13 RADIATORS ANTI-FREEZE 

FUNCTION.

If the system return water is below 4°C, the boiler 

starts up until reaching 42°C.

3.14 P.C.B. PERIODICAL SELF-CHECK.

During functioning in central heating mode or 

with boiler in stand-by, the function activates 

every 18 hours after the last boiler check/power 

supply. In case of functioning in domestic hot wa-

ter mode the self-check starts within 10 minutes 

after the end of the withdrawing in progress, for 

duration of approx. 10 seconds.

N.B.:

 during self-check, the boiler remains off, 

including signalling.

3.15 SOLAR PANELS COUPLING 

FUNCTION.

The boiler is set-up to receive pre-heated water 

from a system of solar panels up to a maximum 

temperature of 65°C. In all cases, it is always ne-

cessary to install a mixing vale on the hydraulic 

circuit upstream from the boiler on the cold 

water inlet.

Note: 

for good functioning of the boiler; the 

temperature selected on the solar valve must 

be 5 °C greater with respect to the temperature 

selected on the boiler control panel.
In this condition, parameter P0 (DHW ther-

mostat) must be set at “1” and the parameter P1 

(solar delay time) at a temperature sufficient to 

receive water from a storage tank situated upstre-

am from the boiler. The greater the distance from 

the storage tank, the longer the stand-by time 

to be set. When these regulations have been 

performed, when the boiler inlet water is at the 

same or greater temperature with respect to that 

set by the DHW selector switch, the boiler does 

not switch on.

3.16 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.
- Visually check the flue hood for deterioration 

or corrosion.

- Check correct lighting and functioning.
- Check correct calibration of the burner in 

domestic hot water and central heating phases.

- Check correct functioning of control and 

adjustment devices and in particular:

  - the intervention of main electrical switch 

positioned outside of the boiler;

  - system control thermostat intervention;
  -  domestic hot water control thermostat inter-

vention.

- Check sealing efficiency of the gas circuit and 

the internal system.

-  Check the intervention of the device against no 

gas ionisation flame control. Intervention time 

must be less than 10 seconds.

-

 

Visually check for water leaks or oxidation 

from/on connections.

-  Visually check that the water safety valve drain 

is not blocked.

- Check that, after discharging system pressure 

and bringing it to zero (read on boiler manome-

ter), the expansion vessel factory-set 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 

shorted, in particular:

  - temperature safety thermostat;
  - water pressure switch,
  - air pressure switch.
- Check the condition and integrity of the elec-

trical system and in particular:

  - electrical power cables must be inside the 

whipping;

  - there must be no traces of blackening or 

burning.

N.B.:

 on occasion of periodical maintenance of 

the appliance it is appropriate also to check and 

perform maintenance on the central heating 

system, in compliance with that indicated by the 

regulations in force.
