all appliances functioning simultaneously.
Never obstruct the air apertures of the burner room, the burner fan intake apertures and any
air duct or ventilation grid and external dissipations, with the purpose of preventing:
- the formation of toxic/explosive gas mixtures in the air of the burner room;
- combustion with insufficient air, from which dangerous, costly and polluting functioning
occurs.
The burner must always be protected from rain, snow and freezing.
The burner room must always be kept clean and free from volatile substances, which could
be sucked inside the fan and block the interior pipes of the burner and the combustion head.
Dust is extremely dangerous, especially if this can deposit on the fan blades, where it will
reduce ventilation and produce pollution during combustion. The
dust an also accumulate on the rear part of the flame stability disc in the combustion head
and cause a poor air/fuel mixture.
The burner must be fed with the type of fuel for which it has been set-up as indicated on the
data plate and in the technical features supplied in this manual. Moreover, it must be supplied
with all control and safety devices requested by local regulations in force. Pay great care that
no external material enters the line during installation.
Make sure that the electric power supply used for the connection is in compliance with the
features indicated on the data plate and in this manual.Make an electric plant with an effecti-
ve connection to an earth plant, in compliance with Standards in force.
The earth cable must be a couple of cm. longer that the phase and neutral wire.
If in doubt regarding efficiency, it must be checked and controlled by qualified staff.
Never exchange the neutral and phase cables.
The burner can be connected to the mains electricity with a plug-socket connection only if
this is equipped in a way that the coupling configuration prevents the inversion of phase and
neutral.Install an omnipolar switch with opening between contacts of at least 3mm upstream
from the appliance as requested by the existing legislation.
The entire electric system and in particular all cable sections, must be suitable for the maxi-
mum absorbed power value indicated on the appliance data plate and in this manual.
If the burner power supply cable is faulty, it must only be replaced by qualified staff.Never
touch the burner with wet body parts or without wearing shoes.
Never stretch (force) power supply cables and keep them away from heat sources.The length
of the cables used must allow the burner and any boiler door to be opened.
The electric connections must be made exclusively by qualified staff and the regulations in
force on the subject of electricity must be respected.
After all packaging material has been removed, control the contents and ensure that these
have not been damaged in any way during transport.
If in doubt, do not use the burner and contact the supplier.
The packaging materials (wooden cages, cardboard, plastic bags, expanded materials, sta-
ples, etc...) represent a form of pollution and potential risk if left everywhere.
