10.3 GAS CONVERSION OPERATIONS
Converting the appliance to another gas type can be performed
easily once the boiler is installed.
The boiler is designed to operate with methane gas G20)
according to the product label. It is possible to convert the
boilers from one gas type to another by using the appropriate
kit supplied upon request:
- Methane conversion kit
- LPG conversion kit
For disassembly refer to instructions below:
- remove power supply from the boiler and close the gas tap
- remove in sequence: shell, air distribution box over and
combustion chamber cover (fig. 22)
- disconnect the spark plug cable connection
- slide off the lower cable grommet from the seat of the air
distribution box
- remove the burner fixing screws and remove burner with the
spark plug attached and corresponding cables
- using a socket or spanner, remove the injectors and the
washers and replace them with the ones in the kit.
Use and assemble the washers contained in the kit also in
case of manifolds without washers.
- reinsert the burner in the combustion chamber and tighten
the screws fixing it to the gas manifold
- place the cable grommet with the spark plug cable in its
seat in the air distribution box
- restore connection of the spark plug cable
- refit the combustion chamber cover and the cover of the air
distribution box
- overturn the control instrument panel towards the boiler front
part
- open the card cover
- on the control card:
- if the conversion is from methane gas to LPG, insert the
jumper in position JP3
- if the conversion is from LPG to methane gas, remove the
jumper from position JP3
- reposition the components previously removed
- restore voltage to the boiler and reopen the gas tap (with
boiler in operation, check correct seal of the gas feeding
circuit connections).
Conversion must be carried out by qualified personnel.
After conversion, adjust the boiler again following the
indications in specific section and apply the new
identification label contained in the kit.
