All burners factory tested at 220V 60 Hz monophase (Max Gas 350) or 380 V 60 Hz three-phase (Max Gas 500) for
motors and 220V 60 Hz monophase for auxiliary equipment. If mains supply is 220 V 60 Hz threephase withuot neu-
tral, change position of connectors on burner as in fig. Protect burner supply line with safety fuses and any other devi-
ces required by safety standards obtaining in the country in question.
Once connected the burner to the gas pipeline, it is necessary to control that this last is perfectly sealed. Also verify that
the chimney is not obstructed. Open the gas cock and carefully bleed the piping through the pressure gauge connector,
then check the pressure value trough a suitable gauge. Power on the system and adjust the thermostats to the desired
temperature. When thermostats close, the sealing control device runs a seal test of valves; at the end of the test the bur-
ner will be enabled to run the start-up sequence.
