Gas valve calibration

- Power the boiler.
� Open the gas tap.
� Turn the function selector to OFF/RESET (digit "��") (fig. 10�11).
� Press the combustion analysis button CO (fig. 4).
� Wait for the burner to ignite, "CO" is displayed on the digital di-
splay and the boiler works at maximum heating power. The flue
cleaner function remains active for a maximum of 15 min� if a
delivery temperature of 95°C is reached, the burner switches off.
It is re-ignited when this temperature falls below 75°C.
� Remove the screw C and the plug D and insert the fumes analy-
sis probe (fig. 37).
- Turn the HTG trimmer clockwise until it reaches the maximum
fan rpm (see table).
� Check the CO value: if the value does not match that indicated
2
in the table, turn the maximum gas valve ad�ustment screw (A,
fig. 36).
- Turn the HTG trimmer anti-clockwise until it reaches the mini-
mum fan rpm (see table).
� Check the CO2 value: if the value does not match that indicated
in the table, turn the minimum gas valve ad�ustment screw (�,
fig. 36).

- Turn the HTG trimmer to the maximum heating fan rpm (see
table)
� To exit the flue cleaner function, turn the function selector (8, fig.
1)
� Remove the fumes analysis probe and put back the screw and
the plug.
Remount the knobs on the panel. The "combustion analysis" fun-
ction automatically deactivates if the board generates an alarm.
If a fault develops during the combustion analysis phase, perform
the release procedure as follows:
Turn the function selector to
required function.

15 - GAS CONVERSION

It is easy to convert from one gas family to another even after the
boiler has been installed.
This operation must be performed by professionally qualified staff.
The boiler is designed to work with natural gas (G20), as indicated
on the product plate.
The boiler can be converted to propane using the relative kit sup-
plied as an accessory.
To disassemble, proceed as follows (fig. 38):
� disconnect the boiler from the power supply and close the gas
tap
- remove the shell and cover of the air distribution box
- release the panel and turn it forwards
- remove the gas pipe (A)
� remove the nozzle (�) contained in the gas train and replace it
with the one contained in the kit
- remount the gas train (check that the gas pipe connected to the
fan mixer is in position)
- put back the air distribution box cover
- power the boiler and open the gas tap.

The boiler may only be converted by qualified staff.
After conversion, apply the new identification plate contained in
the kit.

16 - CHECKING COMBUSTION PARAMETERS

To analyse combustion, proceed as follows:
� turn the function selector to OFF/RESET (digit "��")
� unscrew screws A, remove instrument panel � and press the CO
combustion analysis button (C) (fig. 4).
� insert the analyser probes in the relative positions on the air di-
stribution box, after removing the screw G and the plug F (fig. 37)
� check that the values of CO2 correspond to those indicated in
the table.
If the value displayed is different, modify it as indicated in the
"Gas valve calibration" section
- check combustion.
Then:
� remove the analyser probes and close the combustion analysis
taps with the relative screw cap
- re-mount the instrument panel
The fumes analysis probe must be fully inserted.
