TECHNICAL DATA
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 Technical
Assistance Service).
If the appliance needs 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.
To convert to another type of gas the following operations are
required:
- disconnect power to the appliance;
- replace the main burner injectors, making sure to insert the
special seal rings supplied in the kit, between the gas manifold
and the injectors;
- re-power the appliance;
- use the boiler push button control panel to select the gas parameter
type (G1) and select (Ng) in case of Methane supply or (Lg) in the
case of LPG;
- adjust the boiler nominal heat output;
- adjust the boiler minimum heat power;
- adjust the boiler minimum heat output in heating phase;
- adjust (eventually) the maximum heating power (Parag. 3.8
parameter P5);
- 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 nameplate. Using an indelible
marker pen, delete the data relative to the old type of gas.
ese adjustments must be made with reference to the type of
gas used, following the indications given in the table (Par.4.1).
Checks following conversion to another type of gas.
Aer making sure that conversion was carried out with a nozzle
of suitable diameter for the type of gas used and the settings are
made at the correct pressure, check 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);
ATTENTION:
e pressure testers used for calibration
should be perfectly closed and there
should be no leaks from the gas circuit.
Maintenance interventions must be carried out by
an authorised company (e.g. Authorised Aer-Sales
Technical Assistance Service).
Burner adjustment must be carried out using a dierential "U"
or digital type pressure gauge connected to the pressure socket
located above the sealed chamber and the gas valve pressure point,
keeping to the pressure value given in the table according to the
type of gas for which the boiler is prepared.
