2.3 FIRING RATE
TEST BOILER
The firing rate has been defined according to EN 676 standard.
COMMERCIAL BOILERS
The burner-boiler matching is assured if the boiler conforms to EN 303 and the combustion chamber
dimensions are similar to those shown in the diagram EN 676.
For applications where the boiler does not conform to EN 303, or where the combustion chamber is much
smaller than the dimensions given in EN 676, please consult the manufacturers.
CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 10.5 mbar, is measured (M2, see chapter 3.6, page
7) with the combustion chamber at 0 mbar using gas G20 with a net heat value of 10 kWh/m3(8.570 kcal/m3).

NOTES
The burners have been type-approved for intermittent opera-
tion. This means they must stop at least once every 24 hours in
order to allow the electrical control box to check its efficiency on
start-up. The boiler limit thermostat (TL) normally ensures the
burner halts. If this does not happen a time switch halting the
burner at least once every 24 hours must be applied in series to
limit thermostat (TL).

4. WORKING
4.1 COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC
the application of the burner on the boiler,
adjustment and testing must be carried out
observing the instruction manual of the
boiler, including verification of the CO and
CO2concentration in the flue gases, their
temperatures and the average temperature
of the water in the boiler.
To suit the required appliance output, choose
the proper setting of the combustion head, and
the air damper opening.
4.2 COMBUSTION HEAD SETTING,
(see fig. 9)
The combustion head leaves the factory
set for the maximum output (set point 8).
Setting depends on the output of the burner.
Rotate the setting screw (6) in a clockwise or
anticlockwise direction until set point marked
on the regulating rod (2) is level with the out-
side plane of the head assembly (1).
Figure 9 shows the head regulating rod set
on set point 3.
REMOVING THE HEAD ASSEMBLY
To remove the head assembly, carry out the
following operations:
Make sure servomotor (7) is in the closing
position (CAM II = 0).
Disconnect the connections (3 and 5).
Loosen the screws (4) and remove the ser-
vomotor (7).
ATTENTION
Rotation shaft (10) managed by the servo-
motor (7) features a safety mechanism (11)
that prevents it turning accidentally whilst
maintenance work is in progress.
Loosen the screw (9), loosen screws (8)
and remove head-holder assembly (1) by
rotating slightly to the right.
Take care not to alter the regulating rod-el-
bow (2) position while disassembling.
REASSEMBLY OF THE HEAD SYSTEM
Refit following the above procedure in the
reverse order, restoring the head assembly (1)
to its original position.
ATTENTION
Tighten the screws (9) (without locking them) completely; then lock them with a torque wrench setting of 3 - 4 Nm.
Control that, during the working, there are not gas losses coming from the screws.

4.3 SETTING OF THE AIR DAMPER SERVOMOTOR, (see fig. 11)
CAM II assures the fully closed position of the air
damper, when the burner is shut down (stand by).
It is adjusted by the factory at 0°. DO NOT ALTER.
CAM III adjusts the air damper for the ignition and
for the minimum output. It can be adjusted whilst it
is being put into service. CAM IV is integral with
CAM III.
CAM I regulates the position of the air damper
when the burner is working at maximum output,
and must be used to limit the burner delivery
(adapting it to the boiler delivery). It is factory-regu-
lated at 90°.
The servomotor only follows adjustment of CAM III when the cam’s angle is reduced.
If the cam’s angle needs increasing, you must first increase the servomotor angle with the “increase output (+)”
key, then increase the angle of CAM III and, lastly, return the servomotor to the MIN output position with the “de-
crease output (-)” key.
Where necessary, CAM III can be adjusted by removing cover (1), which is snapped on, as illustrated in fig. 12,
removing the relevant key (2) from inside, and inserting it in the slot on CAM III.
S7025
For the burner to operate over 140 kW, you must remove the
blank deadening to free the supplementary slits of the air inlet on
the cover, as illustrated in figure 10.

You can obtain the adjustment of the intermediate maximum output (100 and 150 kW), than the
maximum absolute of 200 kW, limiting the cam I opening of the servomotor.
By means of this adjustment, the indication of the servomotor position will show the partial load.
Therefore, the PLC software will foresee the possibility “to decrease" this indication according to the
necessity.

4.5 COMBUSTION CHECK
In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjustment and
testing must be carried out observing the instruction manual of the boiler, including verification of the CO and CO2
concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.
It is advisable to set the burner according to the type of gas used and following the indications of the table:
IONIZATION CURRENT
The minimum current necessary for the control box operation is 2 µA.
The burner normally supplies a higher current value, so that no check is needed. Anyway, if you want to
measure the ionization current, you have to open the connector (CN3), (see electrical scheme page 8) fitted
on the wire and insert a microammeter.
4.6 AIR PRESSURE SWITCH
Adjust the air pressure switch once you have performed all the other burner adjustments with the air pressure
switch set to the start of the scale. With the burner operating at minimum output, turn the knob slowly clockwise
until the burner locks out. Next, turn the knob anticlockwise by a value of approx. 20% of the set value and then
make sure the burner starts properly. If the burner locks out again, turn the knob just a bit further anticlockwise.
Attention:
As a rule, the air pressure switch must prevent the air pressure from lowering below 80% of the adjustment
value as well as preventing the CO in the fumes from exceeding 1% (10,000 ppm).
To check this, insert a combustion analyser into the chimney, slowly close the fan suction inlet (for example
with cardboard) and check that the burner locks out, before the CO in the fumes exceeds 1%.

4.8 BURNER START-UP CYCLE
5. MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in conform-
ity with legislation and local standards.
Maintenance is essential for the reliability of the burner, avoiding the excessive consumption of fuel and
consequent pollution.
Before carrying out any cleaning or control always first switch off the electrical supply to the
burner acting on the main switch of the system.
THE BASIC CHECKS ARE:THE FUNDAMENTAL OPERA-
TIONS TO CARRY OUT ARE AS FOLLOWS:
Check at regular intervals that the holes of the gas head are
not obstructed. If they are, clean them with a suitable tool as
shown in the figure 15.
Check there are no occlusions or obstructions in the inlet or
return pipes, in the air suction areas and in the combustion
product waste pipe.
Check that the burner and gas train electrical connections are
correct.
Check that the gas train is suited to the burner capacity, the type
of gas used and the network gas pressure.
Check that the positioning of the combustion head is correct
and that it is properly fixed to the boiler.
Check that the air damper is positioned correctly.
Check that the ionisation probe and the electrode are positioned correctly (see fig. 8, page 7).
Check that the air pressure switch and the gas pressure switch are set correctly.
Leave the burner working without interruptions for 10 min. and checking the right 1st and 2nd stage
settings of all the components stated in this manual.
Then carry out a combustion check verifying:
CO2percentage (%); CO content (ppm); NOx content (ppm); Ionisation current (µA);
Flue gases temperature at the stack.

6. FAULTS / SOLUTIONS
The control box has a self-diagnostic system, by which it is possible to easily check the faults and find the
solutions.
To use this function, wait for a minimum of 10 sec after the lock out, then push the reset button for 3 sec.
After releasing the button, the RED LED will begin to flash, as shown in the following schedule.
The LED provide a blink code each 3sec.
The blink codes give the information of the possible faults, as follows:

7. GENERAL INFORMATION
IDENTIFICATION
The Identification Plate on the product gives the serial number, model and main technical and performance
data. If the Identification Plate is tampered with, removed or missing, the product cannot be clearly identified
thus making any installation or maintenance work potentially dangerous.
GENERAL 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 contract for any damage caused to people, ani-
mals and property due to installation, adjustment and maintenance errors or to improper use.
USER INFORMATION
If faults arise in ignition or operations, the burner performs a "safety stop", which is signalled by the red
burner lock out Led. To rearm start up conditions, press the release button.
When the burner starts up again, the red Led goes out. This operation can be repeated for a maximum of 3
times.
If the "safety stop" recurs, then the Technical Assistance Centre must be called out.
BASIC SAFETY MEASURES
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 covered up with cloths, paper or any other material.
Unauthorised persons must not attempt to repair the appliance.
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 substances (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 in the installation room.

8. ACCESSORIES
PC INTERFACE KIT: code 3002719
MULTIBLOC ROTATION KIT
There is a special kit available that can be used to install the burner turned 180°, as illustrated on page 5 in
position 5 in the section entitled "3.1 WORKING POSITION". This kit is designed to ensure the gas train
valve works properly.
The kit must be installed in conformity with laws and local regulations.
KIT POTENTIOMETER FOR INDICATION OF LOAD POSITION: code 3010109
OUTPUT POWER REGULATOR KIT
Under modulating operation, the burner automatically adapts to one of an infinite number of firing rates
between the low and high flame output position, thus ensuring stable operating conditions in terms of tem-
perature or pressure. Two components should be ordered
– power regulator to install to the burner;
– probe to install to the boiler.
