● On noticing the smell of gas do not touch any electrical switch. Open all doors and windows. Shut off the
gas cocks. Call qualified personnel.
● The room where the burner is located must have the openings required by local regulations in force.
Should you have any doubts as to the circulation of the air in the room, then you should first measure the
CO value with the burner working at its maximum delivery and with the room ventilated solely by means
2
of the openings that feed air to the burner; a second CO
open. The CO value should not vary very much from the first to the second reading. Should there be more
2
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 pollution.
● 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 reduce 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 capacity indicated 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.
