ENGLISH
To finish the calibration function without storing the set values, proceed
as follows:
a) set the mode selector to position (OFF)
b) remove power supply voltage
c) remove JP1/JP2
The calibration function is automatically finished, without storing mini -
mum and maximum values, after 15 minutes of its activation.
The function is automatically finished also in case of definitive stop or
lockout.
Also in this case, function conclusion DOES NOT provide values storing.
Note
To calibrate only maximum heating, it is possible to remove the jumper JP2
(to store the maximum) and then get out from the function, without storing
the minimum, setting the mode selector to (OFF) or removing the voltage
from the boiler.
After each intervention on the adjustment element of the gas valve,
seal it with sealing varnish.
When adjustment is complete:
- Restore set temperature with the ambient thermostat to the desired tem-
perature
- Set the heating water temperature selector to the desired position
- Close the instrument panel
- Pull the shell back in place
4.6 GAS CONVERSION OPERATIONS
The boiler is designed to operate with methane gas (G20) or LPG according
to the product label.
It is possible to convert the boilers from one gas type to another by using
the appropriate kit supplied upon request:
- Methane conversion kit
- LPG conversion kit
Conversion must be carried out by qualified personnel.
After conversion, adjust the boiler again following the indications
in specific section and apply the new identification label contai -
ned in the kit.
For disassembly refer to instructions below:
- R emove power supply from the boiler and close the gas tap
- Remove in sequence: shell, air distribution box cover and combustion
chamber cover
- Disconnect the spark plug cable connection
- Slide off the lower cable grommet from the seat of the air distribution box
- R emove the burner fixing screws and remove the latter with the spark plug
attached and corresponding cables
- Using a socket or fork spanner, remove the nozzles and the washers and
replace them with the ones in the kit
Use and assemble the washers contained in the kit also in case
of manifolds without washers.

- T o convert from natural gas to LPG, mount the flange and fix it to the burner
with the supplied screws
- T o convert from LPG to natural gas, remove (if present) the rear flange
from the burner.
- Reinsert the burner in the combustion chamber and tighten the screws
fixing it to the gas manifold
- Place the cable grommet with the spark plug cable in its seat in the air
distribution box
- Restore connection of the spark plug cable
- R efit the combustion chamber cover and the cover of the air distribution
box
- Overturn the control instrument panel towards the boiler front part
- Open the card cover
- O n the control card (fig. 8):
- I f the conversion is from methane gas to LPG, insert the jumper in position
JP3
- I f the conversion is from LPG to methane gas, remove the jumper from
position JP3
- R eposition the components previously removed
- R estore voltage to the boiler and reopen the gas tap (with boiler in ope -
ration, check correct seal of the gas feeding circuit connections).
5 - MAINTENANCE
To ensure product characteristics and efficiency remain intact and to com -
ply with prescriptions of current regulations, it is necessary to render the
appliance to systematic checks at regular intervals.
Control frequency depends on the installation and use conditions, but it is
therefore necessary an annual check-up by the authorised personnel from
the Technical Assistance Service.
Turn off the appliance to carry out the maintenance of the structure near
the flue exhaust connections or devices, and their accessories. Once the
interventions are finished a qualified technician must check that the pipes
and the devices work correctly.
IMPORTANT: before carrying out any cleaning or maintenance operation of
the appliance, use the appliance and system switch to interrupt power supply
and close the gas supply turning the tap placed on the boiler.
Do not clean the appliance or its parts with inflammable substances (e.g.
petrol, alcohol, etc.).
Do not clean panels, painted parts and plastic parts with paint thinner.
Panel cleaning must be carried out only with soapy water.
5.1 Check the combustion parameters
To carry out the combustion analysis, proceed as follows:
- Open the hot water tap to its maximum output
- Set the mode selector to summer and the domestic hot water tempe-
rature selector to the maximum value
- R emove the screw of the combustion analysis inlet cover (fig. 30) and
insert the probes
- Power the boiler
The appliance works at maximum output and it is possible to check com-
bustion.
After analysis is complete:
- Close the hot water tap
- R emove the probe from the analyser and close the combustion analysis
inlet fastening carefully the screw previously removed.
