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 other items. Inattention, thoughtlessness and excessive confi-
dence often 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 dan-
gerous.
In particular:
it can be applied to boilers operating with water, steam, diather-
mic oil, and to other users 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 envisaged by the manufacturer can be
replaced.
3.2 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;
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;
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.
In addition:
3 Safety and prevention
WARNING
The manufacturer guarantees safety and proper
functioning only if all burner components are intact
and positioned correctly.
the user must take all the measures neces-
sary to prevent unauthorised people gaining
access to the machine;
the user must inform the manufacturer if
faults or malfunctioning of the accident pre-
vention systems are noticed, along with any
presumed danger situation;
Personnel must always use the personal pro-
tective equipment envisaged by legislation
and follow the indications given in this manual.

4.7 Firing rates
The MAXIMUM OUTPUT is chosen from within the continuous
diagram area (Fig. 2).
The MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram:
RS 1000/M BLU = 4000 kW
RS 1200/M BLU = 5500 kW
4.8 Test boiler
The burner/boiler combination does not pose any problems if the
boiler is EC approved and its combustion chamber dimensions
are similar to those indicated in the diagram (Fig. 3).
If the burner must be combined with a boiler that has not been EC
approved and/or its combustion chamber dimensions are clearly
smaller than those indicated in the diagram, consult the manufac-
turer.
The firing rates were obtained in special test boilers, according to
EN 676 regulations.
In Fig. 3 you can see the diameter and length of the test combus-
tion chamber.
Example:
Output 7000 kW - diameter 120 cm - length 6 m.
MODULATING RATIO
The modulating ratio, obtained in test boilers in accordance with
standard EN 676, is 2.5:1.
WARNING
The firing rate value (Fig. 2) has been obtained
considering an ambient temperature of 20 °C, an
atmospheric pressure of 1013 mbar (approx. 0 m
a.s.l.), and with the combustion head adjusted as
shown on page 18.

assistance, etc.) must be carried out by qualified personnel.
Before modifying the wiring in the control box connection
area, fully disconnect the system from the power supply
(omnipolar separation). Check the system is not powered
and cannot be accidentally reconnected. Failure to do this
will lead to the risk of electrocution.
Protection against electrocution from the control box and all
connected electric components is obtained with the correct
assembly.
Before any intervention (assembly and installation opera-
tions, assistance, etc.), ensure the wiring is in order and that
the parameters are correctly set, then make the safety
checks.
Falls and collisions can negatively affect the safety func-
tions.
In this case, the control box must not be operated, even if it
displays no evident damage.
For the safety and reliability of the control box, comply with the
following instructions:
– avoid conditions that can favour the development of conden-
sate and humidity. Otherwise, before switching on again,
make sure that the entire control box is perfectly dry!
– Static charges must be avoided since they can damage the
control box’s electronic components when touched.

5.1 Notes on safety for the installation
After carefully cleaning all around the area where the burner will
be installed, and arranging the correct lighting of the environ-
ment, proceed with the installation operations.
5.2 Handling
The packaging of the burner includes a wooden platform, so it is
possible to move the burner (still packaged) with a transpallet
truck or fork lift truck.
5.3 Preliminary checks
Checking the consignment
Checking the characteristics of the burner
Check the identification label of the burner (Fig. 8), showing:
A the burner model;
B the burner type;
C the cryptographic year of manufacture;
D the serial number;
E the data for electrical supply and the protection level;
F the electrical power consumption;
G the types of gas used and the relative supply pressures;
H the data of the burner's minimum and maximum output pos-
sibilities (see Firing rate)
Warning. The burner output must be within the boiler's firing
rate;
I the category of the appliance/countries of destination.
5 Installation
DANGER
All the installation, maintenance and disassembly
operations must be carried out with the electricity
supply disconnected.
WARNING
The installation of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.
DANGER
Combustion air inside the boiler must be free from
hazardous mixes (e.g.: chloride, fluoride, halo-
gen); if present, it is highly recommended to carry
out cleaning and maintenance more frequently.
WARNING
The handling operations for the burner can be
highly dangerous if not carried out with the great-
est attention: keep any unauthorised people at a
distance; check the integrity and suitableness of
the available means of handling.
Check also that the area in which you are working
is empty and that there is an adequate escape
area (i.e. a free, safe area to which you can quick-
ly move if the burner should fall).
When handling, keep the load at not more than
20-25 cm from the ground.
After positioning the burner near the installation
point, correctly dispose of all residual packaging,
separating the various types of material.
CAUTION
Before proceeding with the installation operations,
carefully clean all around the area where the burn-
er will be installed.
CAUTION
After removing all the packaging, check the integ-
rity of the contents. In the event of doubt, do not
use the burner; contact the supplier.
The packaging elements (wooden cage or card-
board box, nails, clips, plastic bags, etc.) must not
be abandoned as they are potential sources of
danger and pollution; they should be collected and
disposed of in the appropriate places.
WARNING
A burner label, or any other component, that has
been tampered with, removed or is missing, pre-
vents the definite identification of the burner and
makes any installation or maintenance work difficult.

5.9 Electrodes adjustment
5.10 Combustion head adjustment
The air damper servomotor 4)(Fig. 4), beyond varying the air out-
put according to the output demand, through a leverage varies
the combustion head adjustment.
This system allows an optimum adjustment also at minimum fir-
ing rate. Similarly to servomotor rotation, it is possible to vary the
opening of the combustion head moving the tie-rod on the holes
(5-6-7-8-10)(Fig. 15).
The selection of the hole to be used is determined based on the
maximum output requested, as illustrated in Tab. I.
In the factory, the adjustment is adjusted for the maximum stroke
(hole 10, Fig. 15).
