Safety and prevention

3.1

Introduction

The burners have been designed and built in compliance with
current regulations and directives, applying the known technical
rules of safety and envisaging all the potential danger situations.
It is necessary, however, to bear in mind that the imprudent and
clumsy use of the equipment may lead to situations of death risk for
the user or third parties, as well as the damaging of the burner or oth-
er items. Inattention, thoughtlessness and excessive confidence of-
ten cause accidents; the same applies to tiredness and sleepiness.
It is a good idea to remember the following:

The burner must only be used as expressly described. Any
other use should be considered improper and therefore danger-
ous.

In particular:

it can be applied to boilers operating with water, steam, diather-
mic oil, and to other uses expressly named by the manufacturer;
the type and pressure of the fuel, the voltage and frequency of the
electrical power supply, the minimum and maximum deliveries for
which the burner has been regulated, the pressurisation of the
combustion chamber, the dimensions of the combustion cham-
ber and the room temperature must all be within the values indi-
cated in the instruction manual.

Modification of the burner to alter its performance and desti-
nations is not allowed.
The burner must be used in exemplary technical safety con-
ditions. Any disturbances that could compromise safety
must be quickly eliminated.
Opening or tampering with the burner components is not
allowed, apart from the parts requiring maintenance.
Only those parts detailed as available as spare parts by the
Manufacturer can be replaced.

3.2

Safety warnings

The dimension of the boiler’s combustion chamber must respond
to specific values, in order to guarantee a combustion with the
lowest polluting emissions rate. 
The Technical Service Personnel will be glad to give you all the
imformation for a correct matching of this burner to the boiler.

This burner must only be used for the application it was designed
for. 
The manufacturer accepts no liability within or without the con-
tract for any damage caused to people, animals and property due
to installation, adjustment and maintenance errors or to improper
use.

3.3

Basic safety rules

Children or inexpert persons must not use the appliance.
Under no circumstances must the intake grids, dissipation
grids and ventilation vents in the installation room be cov-
ered up with cloths, paper or any other material.
Unauthorised persons must not attempt to repair the appli-
ance.
It is dangerous to pull or twist the electric leads.
Cleaning operations must not be performed if the appliance
is not disconnected from the main power supply. 

Do not clean the burner or its parts with inflammable sub-
stances (e.g. petrol, alcohol, etc.). The cover must be
cleaned with soapy water.
Do not place anything on the burner.
Do not block or reduce the size of the ventilation vents in
the installation room.
Do not leave containers and inflammable products or com-
bustible materials in the installation room.

3.4

Personnel training

The user is the person, body or company that has acquired the
machine and intends to use it for the specific purpose. He is re-
sponsible for the machine and for the training of the people work-
ing around it.

The user:

undertakes to entrust the machine exclusively to suitably
trained and qualified personnel;
must take all the measures necessary to prevent unauthor-
ised people gaining access to the machine;
undertakes to inform his personnel in a suitable way about
the application and observance of the safety instructions.
With that aim, he undertakes to ensure that everyone knows
the use and safety instructions for his own duties;

must inform the manufacturer if faults or malfunctioning of
the accident prevention systems are noticed, along with any
presumed danger situation.
Personnel must always use the personal protective equip-
ment envisaged by legislation and follow the indications
given in this manual.
Personnel must observe all the danger and caution indica-
tions shown on the machine.
Personnel must not carry out, on their own initiative, opera-
tions or interventions that are not within their province.
Personnel must inform their superiors of every problem or
dangerous situation that may arise.
The assembly of parts of other makes, or any modifications,
can alter the characteristics of the machine and hence com-
promise operating safety. The manufacturer therefore
declines any and every responsibility for any damage that
may be caused by the use of non-original parts.
