• The room where the burner is located must have the openings required by local regu-
lations in force. Should you have any doubts as to the circulation of the air in the room,
then you should first measure the CO2 value with the burner working at its maximum
delivery and with the room ventilated solely by means of the openings that feed air to
the burner; a second CO2 measurment should then be taken with the door open. The
CO2 value should not vary very much from the first to the second reading. Should the-
re be more than one burner and one fan in the same room, then this test must
be carried out with all the appliances working at the same time.
• Never cover up the burner room's air vents, the burner's fan's air-intake openings or
any existing air ducts or air gratings, thus avoiding:
- the formation of poisonous/explosive mixtures of gases in the burner room;
- combustion with insufficient air, which would be dangerous, costly and cause pollu-
tion.
• The burner must at all times be protected from rain, snow and freezing.
• The room where the burner is housed should be kept clean at all times, and there
should be no volatile substances in the vicinity, substances which could be sucked into
the fan and could block up the internal ducts of the burner or combustion head. Dust
can be extremely harmful, particularly when it gets onto the fan blades as this can re-
duce ventilation and lead to pollution during combustion. Dust can also build up on the
rear of the flame stability disk inside the combustion head, leading to a poor air-fuel
mixture.
• The burner must be fed with the type of fuel for which it was designed, as indicated
on the data plate and in the technical characteristics given in this manual. The fuel
feed line must be sealed and must be of the rigid variety, with an interposed metal
expansion coupling with either a flange joint or a threaded joint. Furthermore, the feed
line must be equipped with all the adjustment and safety devices required by the local
regulations in force. Particularly ensure that no foreign bodies get into the feed line
during installation.
• Ensure that the electrical power supply used conforms to the technical characteristics
indicated on the data plate and in this manual. The burner must be connected to an
effective system earthed in accordance with the current regulations. Should there be
any doubts, the verification should be made by qualified persons.
• Never exchange neutral and phase wires.
• The burner can be connected up to the mains supply using a plug connection only
if the latter is of the kind that does not allow neutral and phase wires to be reversed.
Install a main switch for the heating system on the control panel, as required by current
regulations.
• The entire electrical system, and in particular cable cross-sections, should conform
to the maximum absorbed capacityindicated on the appliance data plate and in this
manual.
• Should the burner's mains cable be found faulty, it must only be replaced by qualified
persons.
• Do not touch the burner with parts of the body which are wet or when in bare feet.
• Do not pull (stretch) the mains cables and keep them well away from heat sources.

• The length of the cables used must enable the burner to be opened, as well as the
