ELECTRICAL CONNECTIONS
All burners are factory tested and set at 400 V 50 Hz three-phase for motors and 230 V 50 Hz monophase with neutral
for auxiliaries. If it is necessary to supply the burner at 230 V 50 Hz without neutral,make the necessary alterations
referring to the wiring diagram of the burner and check that the termal relay is within the absorption range of the
motor. Also check that the fan motor rotates in the correct direction.
CONNECTION TO THE GAS PIPELINE
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.
