OPERATION WITH DIFFERENT TYPES OF GAS

CONVERSION FROM NATURAL GAS TO LIQUID GAS
The boiler is factory-set for G20 (Natural Gas) or G30/G31(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 (1) and remove the burner (2) (fig. 1)
- Replace the burner nozzles (3) 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 G20 (Natural Gas) to G30/G31 (LPG):
- Insert the gas diaphram (fig. 2 )
- Move jumper JP1 to ON position (fig. 3)
- Disconnect the pressure regulator by screwing tight the nut (H) (page 50) and adjust minimum pressure to the
value reported in the table shown below by acting on the screw (I) (page 50)
- If necessary, adjust trimmers RLA and R.MAX according to the system features
- Seal the regulator by applying the cover ( G )
