3.7 CONVERTING THE BOILER TO OTHER
TYPES OF GAS.
e gas conversion operation must be carried out by an
authorised company (e.g. Authorised Aer-Sales Cen-
tre).
To convert to another type of gas the following operations are re-
quired:
- Select, via programming menu “G”, the type of gas by selecting
“nG” for methane gas and “LG” for LPG gas (Par. 3.13).
- Alternatively, by accessing the appropriate sub-menu, it is pos-
sible to choose "AP" propane-air gas operation.
- Carry out complete calibration (Par. 3.9); during the procedure
check and, if necessary, correct the CO
2
value.
- Upon completing the conversion, apply the sticker regarding
the modied gas content onto the data nameplate in the connec-
tion box.
ese adjustments must be made with reference to the type of gas
used, following the indications given in the table (Par. 4.2).
Checks following conversion to another type of gas.
Aer having made sure that the conversion is complete and that
the calibration has been successful, you must make sure that:
- there is no ame in the combustion chamber;
- the burner ame is not too high or low and that it is stable (does
not detach from burner);
e pressure testers used for calibration
should be perfectly closed and there
should be no leaks from the gas circuit.
Maintenance operations must be carried out by an au-
thorised company (e.g. Authorised Aer-Sales Techni-
cal Assistance Service).

3.8 CALIBRATION TYPE INVOLVING THE
REPLACEMENT OF A COMPONENT.
When performing extraordinary maintenance on the boiler, in-
volving the replacement of a component, such as the P.C.B. or
components in the air, gas and ame control circuits, the boiler
will need to be calibrated.
Select the type of calibration to be carried out according to the ta-
ble below.
