Conversion of burner gas type
Conversion to LPG
The gas burner is supplied already set for natural gas and with the
kit for conversion to LPG, including: calibrated gas orifi ce plate; pilot
nozzle; adhesive plate “Equipment converted...”.
The kit is not supplied in countries where conversion is prohibited.
To convert the unit, follow these instructions:
■ disconnect from power supply;
■ access the inside of the burner module by removing the 4 Allen
M6 screws that secure the front panel;
Conversion to gas G25 - G25.1 - G25.3 - G27
Conversion for gasses from G20 to G25 or G25.1 or G25.3 or G27
is allowed only in countries of category II2ELL3B/P [Germany],
II2Esi3P [France], II2E3P [Luxembourg] and category II2HS3B/P
[Hungary] and category II2ELwLs3B/P [Poland].
For countries in category II2EK3B/P [Netherlands] the unit is
supplied already set up and regulated for G20 or G25.3.
Conversion from one type of gas to another can only be performed
by authorised service centres.
Note: The conversion kit to G25 , G25.1 and G27 is only supplied
on request. The conversion kit to G25 is included in the standard
supply for France, Germany and Luxembourg.
Conversion to G25 and/or G25.1, G25.3, G27 where possible,
consists in:
■ insertion of orifi ce plate (according to the gas type and the
equipment model).
After the conversion, relight the burner and follow the steps
explained for the conversion to LPG.
Finally, stick the nameplate “Equipment converted for gas G25....”
■ between the gas pipe and the Venturi, replace the gas orifi ce plate
fi tted (natural gas) with the one supplied with the kit (for LPG);
■ replace the pilot nozzle (natural gas) with the one in the kit
(LPG);
■ restore power supply and set the heater up for ignition;
■ while the start-up electrode is sparking, make sure there are
no gas leaks.
When the burner is lit and working at maximum capacity, verify that:
■ the valve intake pressure corresponds to the value required for
the type of gas that you are using;
■ the combustion analysis procedure is performed as described
in paragraph “Analysis of combustion”;
■ the level of CO
2
is within the limits indicated for the type of
gas being used (tables in Paragraph “GAS connection”). If a
diff erent value is detected, change it by turning the adjustment
screw: screwing it down decreases the CO
2
level, loosening it
increases the level.
Note: The heater with LPG is set up for G31 gas. If the unit
runs on G30 instead, it is necessary to verify and possibly
adjust settings for CO
2
as shown in the table in paragraph “Gas
connection”.
■ that the gas valve Venturi pipe connector does not leak.
After converting and regulating the unit, replace the nameplate
indicating “Equipment regulated for natural gas” with the one in the
kit that indicates “Equipment converted ...”.
