CHANGING GAS TYPE
When necessary, it is possible to modify
the boiler to run on types of gas which are
supported but which the boiler was not set
up for in the factory.
This modification concerns in particular
REGULATING COMBUSTION:
•
Regulate combustion as described
on page 29, “Analysis - Checking and
regulating combustion” chapter.
Gas type Parameter value
Natural gas 0
LPG 1
BEFORE COMMISSIONING THE NEWLY CONFIGURED BOILER IT IS NECESSARY TO CHECK THE
GAS SUPPLY PRESSURE BEFORE THE BOILER AND MEASURE AND ADJUST THE GAS PRESSURE
AT THE BURNER. REFER TO THE PRESSURE VALUES AND PROCEDURES GIVEN FOR EACH
SPECIFIC GAS IN THE “TESTING THE GAS SUPPLY DYNAMIC PRESSURE:” CHAPTER (Page 27).
Complete the change by attaching the label A1/A2 indicating the change to the new
type of gas for which the boiler has now been configured, near the technical data plate
located on the rear instrument panel cover.
Proceed as follows to change the system:
CHANGING FROM NATURAL GAS (NG) TO LPG
•
CONFIGURING THE SOFTWARE
• REGULATING COMBUSTION
• APPLY LABEL B1 ON THE GAS VALVE AFTER
REMOVING THE OLD LABEL
CHANGING FROM LPG TO NG
•
CONFIGURING THE SOFTWARE
• REGULATING COMBUSTION
• APPLY LABEL B2 ON THE GAS VALVE AFTER
REMOVING THE OLD LABEL
CONFIGURING THE SOFTWARE FOR A CHANGE IN
GAS TYPE:
•
To adapt the supply driver of the gas regulation
valve modulator it is necessary to enter the
“INSTALLER MENU” (see page 32 for how to
access this menu) and view the value of
parameter “A1”.
• Set the parameter according to the gas supply
and the change performed, following the
values given in the table below:
the change from NG (natural gas) to LPG
(butane / propane) and vice versa.
In order to perform this change the boiler’s
basic configuration must be modified to that
necessary to support the supplied type of gas.
CONVERSIONS MUST ALWAYS BE PERFORMED BY QUALIFIED PERSONNEL
