(the type of gas appears on the display on first electrical power supply,
or by checking the relative parameter “G”);
- check that there is no air in the gas pipe;
- check connection to a 230V-50Hz power mains, correct L-N polarity
and the earthing connection;
- check that the intake/exhaust terminals are not obstructed and
that they are installed properly;
