Information and general warnings
2.1.4 Delivery of the system and the instruction
manual
When the system is delivered, it is important that:
the instruction manual is delivered to the user by the system
manufacturer, with the recommendation to keep it in the
room where the heat generator is to be installed.
The instruction manual shows:
- the serial number of the burner;
- the address and telephone number of the nearest Assis-
tance Centre
The system supplier must carefully inform the user about:
- the use of the system;
- any further tests that may be required before activating the
system;
- maintenance, and the need to have the system checked at
least once a year by a representative of the manufacturer
or another specialised technician.
To ensure a periodic check, the manufacturer recom-
mends the drawing up of a Maintenance Contract.
2.2 Guarantee and responsibility
The manufacturer guarantees its new products from the date of
installation, in accordance with the regulations in force and/or the
sales contract. At the moment of the first start-up, check that the
burner is integral and complete.
In particular, the rights to the guarantee and the responsibility will
no longer be valid, in the event of damage to things or injury to
people, if such damage/injury was due to any of the following
causes:
incorrect installation, start-up, use and maintenance of the
burner;
improper, incorrect or unreasonable use of the burner;
intervention of unqualified personnel;
carrying out of unauthorised modifications on the equipment;
use of the burner with safety devices that are faulty, incor-
rectly applied and/or not working;
installation of untested supplementary components on the
burner;
powering of the burner with unsuitable fuels;
faults in the fuel supply system;
continuation of use of the burner when a fault has occurred;
repairs and/or overhauls incorrectly carried out;
modification of the combustion chamber with inserts that
prevent the regular development of the structurally estab-
lished flame;
insufficient and inappropriate surveillance and care of those
burner components most likely to be subject to wear and
tear;
use of non-original components, including spare parts, kits,
accessories and optional;
force majeure.

Safety and prevention
3.1 Background
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 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 ambient temperature must all be within the values in-
dicated 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.
must take all the measures necessary to pre-
vent 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 man-
ual.

Technical description of the burner
4.11 Electrical control box
The control box is a control and supervision system for forced
draught burners, for intermittent operation (at least one controlled
shutdown every 24 hours).
Important notes
All interventions (assembly and installation operations,
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).
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 safety and reliability, comply with the following instruc-
tions:
- Avoid conditions that can favour the development of conden-
sate and humidity. Otherwise, before switching on again,
make sure the control box is perfectly dry.
- Static charges must be avoided since they can damage the
control box’s electronic components when touched.
Installation notes
• Check the electric wiring inside the boiler complies with the
national and local safety regulations.
• Install switches, fuses, earth connection etc. in compliance
with local regulations.
• Do not confuse the powered conductors with the neutral
ones.
• Ensure that spliced wires cannot get into contact with neigh-
bouring terminals. Use adequate ferrules.
• Arrange the H.V. ignition cables separately, as far as possi-
ble from the control box and the other cables.
• When wiring the unit, make sure the 230V AC mains voltage
cables are run strictly separate from extra low-voltage cables,
to avoid the risk of electrocution.
To remove the control box from the burner it is necessary to (Fig.
6):
disconnect all the connectors connected to it, all the plugs,
the high voltage cables, and the earth wire (TB);
unscrew the screw (A) and pull the control box in the direc-
tion of the arrow.
To install the control box it is necessary to:
tighten the screw A) with a tightening torque of 1 - 1.2 Nm;
reconnect all previously disconnected connectors, making
sure to connect the 7 pin power plug as the final step.
NOTE:
The burners have been approved for intermittent operation.
This means that they must stop once every twenty four
hours to permit the electrical control box to check its effi-
ciency at start up. The boiler limit thermostat (TL) normally
ensures the stopping of the burner. If this is not the case, it
is necessary to apply a timer switch in series to the limit
thermostat (TL) that turns off the burner at least once every
24 hours.
Electrical wiring of ionisation probe
It is important for signal transmission to be almost totally free
of any disturbances or loss:
• Always separate the probe cables from the other cables:
- the line capacity reduces the magnitude of the flame sig-
nal;
- use a separate cable.
• The cable length must not exceed 1 m.
• Respect the polarity
• Insulation resistance:
- must be at least 50 Mbetween the ionisation probe and
the earth;
- a dirty detector reduces the insulation resistance, fostering
leakage currents.
• The ionisation probe is not protected against the risk of elec-
trocution. When connected to the electricity supply, the ioni-
sation probe must be protected against any accidental
contact.
• Position the ionisation probe so that the ignition spark cannot
form an arc on the probe (risk of electric overcharge).

5.1 Notes on safety for the installation
After carefully cleaning all around the area where the burner is to
be installed, and arranging for the environment to be illuminated
correctly, proceed with the installation operations.
5.2 Instructions to avoid burnout or bad combustion of the burner
1 The burner can not be installed outside as it is suitable for
operation in closed rooms only.
2 The premises the burner operates in must have openings
for the air need for the combustion.
To be sure about this, you have to control CO2 and CO in
the exhaust gases with all the windows and doors closed.
3 If there are air extractors in the premises the burner works,
make sure that there are openings for air to be taken in that
are big enough to ensure the required air change; In any
case, check that when the burner stops the extractors do
not draw hot fumes from pipes through the burner.
4 When the burner is stopped, the flue must be kept open and
a natural draft created in the combustion chamber.
If the smoke pipe is closed, the burner must be drawn back
till the extraction of blast tube from the furnace. Before oper-
ating in this way take the voltage off.
5.3 Handling
The transport weight is given in chapter Technical data on
page 9.
Observe the permissible ambient temperatures for storage and
transport: -20... + 70 °C, with max. relative air humidity 80%.
5.4 Preliminary checks
5.4.1 Control of the supply
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.
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.
The operator must use the required equipment
during installation.
CAUTION
After removing all the packaging, check the integ-
rity of the contents.
In the event of doubt, do not use the burner; con-
tact the supplier.
The packaging elements (cardboard box, 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 appro-
priate places.

5.7 Combustion head adjustment
The adjustment of the combustion head varies depending on the
burner output.
This is carried out by turning the adjustment screw 6)(Fig. 12)
clockwise or anti-clockwise until the notch on the regulating rod
2) lines up with the outside surface of the head assembly 1).
In Fig. 12 the head regulating rod is set to notch 3.
Example for the BS3D burner
The diagram (Fig. 13) is indicative and shows the calibration of
the combustion head in relation to the burnt output.
To ensure the burner works efficiently, we suggest adjusting the
combustion head according to the requirements of the specific
boiler.
The burner is installed in a 100 kW boiler. Considering an effi-
ciency of 90%, the burner must supply around 110 kW; for this
burner output the adjustment should be on notch 3.
5.7.1 Removing the head assembly
To remove the head assembly, it is necessary to:
disconnect the connections 3) and 5)(Fig. 12);
remove the tube 4) and loosen the screws 10)(Fig. 12);
unscrew and remove the screws 7), remove the head holder
assembly 1)(Fig. 12) slight rotation to the right.
5.7.2 Reassembling the head assembly
Reverse the procedure above to put back the head assembly
1)(Fig. 12) as it was before.
CAUTION
Take care not to change the setting position on
the elbow-bracket 2)(Fig. 12) when dismantling.
CAUTION
Tighten the screws 7)(Fig. 12), without fully lock-
ing them. Lock them with a tightening torque of 3
- 4 Nm.
WARNING
Check that when operating there are no gas leaks
from the screw housings.
If the pressure test point 13)(Fig. 12) should be-
come slack accidentally, we recommend fixing it
correctly ensuring that the hole (F) in the head as-
sembly 1)(Fig. 12) is facing downwards.
