OPERATION WITH DIFFERENT TYPES OF GAS
CONVERSION FROM NATURAL GAS TO LIQUID GAS
The boiler is factory-set for G0 (Natural Gas) or G0/G(LPG) operation, as mentioned on the Technical
Nameplate and on the apparatus packaging. In the event the heater shall be operated using a different gas
from that conceived by factory setting, a special kit has to be installed, which is to be ordered separately.
To perform conversion, act as follows:
- Remove the cover and open the tight chamber (for model MCS)
-
Unscrew the fastening screws () and remove the burner () (fig. )
-
Replace the burner nozzles () with those supplied with the transformation kit, making sure that the
relevant diameter corresponds to that reported in the table shown below. Insert the sealing rings
-
Reassemble the burner
-
Close the tight chamber checking proper positioning of seal gaskets (for model MCS)
Then act as follows:
For transformation from G0 (Natural Gas) to G0/G (LPG):
- Insert the gas diaphram (fig. )
- Move jumper JP to ON position (fig. )
- Disconnect the pressure regulator by screwing tight the nut (H) (page ) and adjust minimum pressure to
the value reported in the table shown below by acting on the screw (I) (page )
- If necessary, adjust trimmers RLA and R.MAX according to the system features
- Seal the regulator by applying the cover ( G )
For transformation from G0/G(LPG) to
G0 (Natural Gas):
- Remove the gas diaphram
- Move jumper JP to OFF position (fig. )
- Regulate the pressure (maximum and mini-
mum values) of the burner according to the
values reported in the table shown below,
by acting on the nut (H) and on the screw
(I) respectively, as described in paragraph
‘ADJUSTMENTS’ (page )
-
If necessary, adjust trimmers RLA and R.MAX
according to the system features
-
To confirm transformation, apply the adhe-
sive plate supplied with the transformation
KIT on the Technical Nameplate reporting the
information featuring the gas, and according
to the factory-setting.
