3.13 CONVERTING THE BOILER TO OTHER
TYPES OF GAS
If the boiler has to be converted to a dierent gas type
to that specied on the data plate, request the relative
conversion kit for quick and easy conversion.
e gas conversion operation must be carried out by
an authorised company (for example contact the Authorised
Technical Service Centre).
To convert to another type of gas the following operations are
required:
- disconnect the appliance;
- change the sleeve with Venturi (det. 5 g. 26);
- change the gas nozzle (det. 4 g. 26);
- re-power the appliance;
- regulate the maximum heat output by varying the number
of fan revs. (parameter P25 “Max number of fan revs in CH
mode”) according to par. 4.1;
- regulate the minimum heat output by varying the number
of fan revs. (parameter P26 “Min number of fan revs in CH
mode”) according to par. 4.1;
- activate the chimney sweep function;
- check the CO
2
value on the table in par. 4.2, especially:
- check the CO
2
value in the ue with chimney sweep at 0%;
- check the CO
2
value in the ue with chimney sweep at 100%;
- exit the chimney sweep function;
- seal the gas ow rate regulation devices (if settings are modi-
ed);
- aer completing the conversion, apply the sticker, contained
in the conversion kit, near the data-plate. Using an indelible
marker pen, cancel the data relative to the old type of gas.
ese adjustments must be made with reference to the type
of gas used, following that given in the table (Paragraph 4.1).
3.14 CHECKS FOLLOWING CONVERSION TO
ANOTHER TYPE OF GAS.
Aer making sure that transformation was carried out with the
Venturi and a nozzle of suitable diameter for the type of gas used
and the calibration has been performed at the correct num. of
revs, check that:
- the burner ame is not too high and that it is stable (does not
detach from burner);
- there are no leaks from the gas circuit.
All boiler adjustment operations must be carried out
by a qualied technician (for example contact the
Authorised Technical Service Centre).
3.15 CO
2
ADJUSTMENT.
Calibration of minimum CO
2
Turn the boiler on and start the chimney sweep functions at min-
imum output (0%). To have an exact value of CO
2
the technician
must insert the sampling probe to the bottom of the sample point,
then check that the CO
2
value is that specied in the table in par.
3.25, on the contrary, regulate the screws (3 g. 49) (O-Set reg-
ulator). To increase the CO
2
value, turn the adjustment screw (3)
in a clockwise direction and vice versa to decrease it.
Calibration of maximum CO
2
.
When you nish the minimum CO
2
adjustment, turn the boiler
on and start the chimney sweep function at the maximum out-
put (100%). To have an exact value of CO
2
the technician must
insert the sampling probe to the bottom of the sample point, then
check that the CO
2
value is that specied in the table in par. 4.1,
otherwise, adjust the screw (12 g. 49) (gas ow rate regulator).
To increase the CO
2
value, turn the adjustment screw (12) in an
anti-clockwise direction and vice versa to decrease it.
At every adjustment variation on the screw (12) it is necessary to
wait for the boiler to stabilise itself at the value set (about 30 sec.).
