6.5. Conversion to LPG
Conversion is strictly prohibited in some countries, such
as Belgium, which do not allow the double gas category.
The Kit is not supplied in countries where conversion is prohibited.
Conversion from one type of gas to another can only be performed
by authorised service centres.
The unit is supplied already set for natural gas and with the kit
for conversion to LPG, including:
•
calibrated gas orifice plate;
•
adhesive plate "equipment converted..."
To convert the unit, follow these instructions:
•
disconnect boiler from power supply;
•
between the gas valve and the Venturi, replace the gas
orifice plate fitted with the one supplied with the kit;
•
restore power supply and set the boiler 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:
1. the valve intake pressure corresponds to the value required
for the type of gas that you are using;
2. the combustion analysis procedure is performed as
described in paragraph 6.4;
3. the CO
2
level is within the values indicated for the type of
gas used. If the detected value is different, change it using
the adjustment screw: screwing it down decreases the CO
2
level, loosening it increases the level.
4. 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 ...".
N
ote: The boiler supplied to function with LPG is set up
for G31 gas [Propane].
If the unit runs on G30 [Butane], it is necessary to verify and
possibly adjust settings for CO
2
value as shown in table 6.2.
6.6. Replacing the Gas Valve
If the gas valve must be replaced, it is required to proceed with an inspection and possibly calibrate the CO
2
level.
To carry out the calibration, refer to the paragraph concerning the combustion analysis 6.4 and to table 6.2.
