The room where the burner is located must have the openings required by local regulations in force.
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
bend 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.
In accordance with current regulations, the electrical system must be connected to an efficient earth
system. The earth cable must be a couple of cm longer than the phase and neutral wires.
Should there be any doubts, the verification should be made by qualified persons.
Never exchange neutral and live 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 live wires to be reversed. Upstream of the equipment, install
an omnipolar switch with an opening between contacts of at least 3 mm, as required by the laws in
force.
The entire electrical system, and in particular cable cross-sections, should conform to the maximum absorbed
capacity indicated on the 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.
