2 - GAS UNIT DISMANTLING AND NOZZLES CHANGE
To adapt the water heater to a gas different from that of calibration, the main nozzle of the burner and of the pilot must
be replaced.
NOTE:
The nozzles for the adjustment of functioning with gas different to that of calibration, must be
expressly requested by the dealer, if not provided with the appliance.
We recommend proceeding after having dismantled the gas unit.
GAS UNIT DISMANTLING
• Disconnect the cables of the fumes protector; disconnect the piezo ignition cable and remove the gas valve thermostat
probe from the sheath.
• Remove the gas unit by slightly pulling it to the outside and turning it (see fig 18) until full removal of the burner.
