CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 9.3 mbar, relatively to 916T1 model, 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).
3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.
3.1 WORKING POSITION
The burner is designed for operation in position 1only.
Installation in positions 2, 3, 5, 6 and 7is not recommended as it is likely to hinder the unit’s proper operation
since air damper closure cannot be guaranteed when the burner is on standby.
Installation in position 5is only possible using the “MULTIBLOC rotation kit”, to be ordered separately.
Installation 4is prohibited as safety is compromised.

4. WORKING
4.1 COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC
the application of the burner on the boiler, adjust-
ment and testing must be carried out observ-
ing the instruction manual of the boiler,
including verification of the CO and CO2con-
centration in the flue gases, their tempera-
tures and the average temperature of the
water in the boiler. To suit the required appli-
ance output, choose the proper setting of the
combustion head, and the air damper opening.
4.2 COMBUSTION HEAD SETTING,
(see fig. 9)
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.
Example for BS3D burners:
The burner is installed in a 100 kW boiler.
Taking an efficiency level of 90% the burner
should give an output of app. 110 kW with the
regulating rod set at set point 3as shown in
the diagram.
The diagram is for indication purposes: to as-
sure good working from the burner we sug-
gest adjusting the combustion head according
to the boiler.
REMOVING THE HEAD ASSEMBLY
Proceed as follows to remove the head assembly:
Disconnect the connections (3 and 5).
Extract the small tube (4) and loosen the
screws (10).
Unscrew and remove the screws (7), pull
out the head assembly support (1) turning
it slightly to the right.
Take care not to change the setting posi-
tion on the elbow-bracket (2) during dis-
mantling.
REASSEMBLING THE HEAD ASSEMBLY
Follow the above instructions in reverse, re-
turning the head assembly (1) to its original
position.
WARNING
Tighten the screws (7) completely (without
locking them); then lock them with a torque
wrench setting of 3-4 Nm.
Check there are no gas leaks from the screws during these operations.
If the pressure test point (13) should work loose, it must be correctly fixed ensuring that the hole (F) in-
side the head assembly (1) is facing downwards.

4.3 AIR DAMPER ADJUSTMENT, (fig. 10)
First start-up must always be performed, adjusting screw (12), so
that the 1st stage air damper position pointer is beyond mark 1,
(factory setting mark 1).
To adjust, proceed as follows:
Take the burner to 2nd stage by closing the T6-T8 connection found
in the 4-pin plug (X4, wiring on page 8).
Fan thrust causes the air damper to go to the 2nd-stage position with
reference to the factory setting (screw 8 on mark 3).
Loosen nut (9) and turn screw (8) to adjust 2nd-stage air flow (see
CO2values given in the table below).
Take the burner to 1st stage by opening the T6-T8 connection found
in the 4-pin plug (X4, page 8).
Adjust 1st stage by turning screw (12), loosening (clockwise) nut (11)
first, referring to the table below for CO2values.
Once you have achieved the optimal setting, tighten (anticlock-
wise) nut (11). When the burner stops, the air damper closes
automatically under its own weight until maximum negative flue
pressure is 0.5 mbar.
To adjust 1st and 2nd stage output, follow the instructions below:
Output ratio between 1st and 2nd stage must be no more than 1:2.
Example for BS3D: 2nd stage output required 140 kW;
Minimum 1st stage output no less than 70 kW.
Whatever the case, the burner's minimum 1st stage output must not be lower than the value indicated in
the operating range.
Example for BS3D: 2nd stage output required 110 kW;
Minimum 1st stage output no less than 65 kW (minimum in operating range page 4).
4.4 COMBUSTION CHECK
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 con-
trol box operation is 5 μA.
The burner normally supplies a higher cur-
rent value, so that no check is needed. Any-
way, if you want to measure the ionization
current, you have to open the connector
(CN1) (see electrical scheme page 8) fitted
on the wire and insert a microammeter.

4.5 AIR PRESSURE SWITCH
The air pressure switch is set after all other adjustments have been made. Begin with the switch at the
lowest setting. With the burner working at the required output, adjust the dial clockwise, increasing its value
until the burner shuts down. Now reduce the value by one set point, turning the dial anti-clockwise. Check
for reliable burner operation, if the burner shuts down, reduce the value by a half set point.
ATTENTION:
To comply with the standard, the air pressure switch must operate when the CO value exceeds 1%
(10,000 ppm). To check this, insert a combustion analyser in the flue, slowly reduce the burner air setting and
verify that the burner shuts down by the action of the air pressure switch before the CO value exceeds 1%.
4.6 BURNER START-UP CYCLE
Lock-out is indicated by a lamp on the control box (4, fig. 1, page 2).
4.7 RE-CYCLE FUNCTION
The control box allows re-cycling, i.e. the complete repetition of the starting programme, for 3 attempts maxi-
mum, in the event the flame goes out during operation.
4.8 POST-VENTILATION FUNCTION
Post-ventilation is a function that maintains air ventilation even after the burner is switched off. The burner
switches off when the limit thermostat (TL) opens, cutting off the fuel supply to the valves.
To use this function the reset button must be pressed when the limit thermostat is not switched over
(BURNER SWITCHED OFF).
Post-ventilation time can be set to a maximum of 6 minutes. Proceed as follows:
Press and hold the reset button for at least 5 seconds till the LED indicator changes to red.
Set the desired time pressing the button repeatedly: once = post-ventilation for 1 minute.
After 5 seconds the control box automatically shows the minutes set by the red LED flashing:
1 pulse = post-ventilation for 1 minute.
To reset this function, press and hold the button for at least 5 seconds the LED indicator changes to red then
release it without carrying out any operation, then wait for 20 seconds for the burner to start.
If during post-ventilation there is a new request for heat, post-ventilation time is halted and a new operating
cycle starts when the limit thermostat (TL) switches over.
The control box leaves the factory with the following setting: 0 minutes = no post-ventilation.
4.9 CONTROL BOX RESET
To carry out the control box reset, proceed as follows:
Press the reset button for at least 1 second.
In the event of the burner not restarting it is necessary to check if the limit thermostat (TL) is closed.

5. MAINTENANCE
Disconnect the electric supply to the burner by switching off the main power switch and close the
gas shut-off valve before maintaining or checking the system.
The burner requires scheduled maintenance that must be carried out by qualified personnel and in compli-
ance with local legislation.
Scheduled maintenance is vital for the smooth operation of the burner; it avoids waste of fuel and reduces
harmful emissions into the atmosphere.
THE FUNDAMENTAL OPERATIONS 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 11.
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 positioning of the air pressure test point (6, fig.
1, page 2) is 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. 5, page 6).
Check that the air pressure switch and the gas pressure switch are set correctly.
Leave the burner operating in steady state for approx. ten minutes, checking to ensure that all elements
indicated herein have the proper settings for 1st and 2nd stage.
Then carry out the analysis of the combustion by checking:
CO2percentage (%); CO content (ppm); NOx content (ppm); Ionisation current (μA);
Flue gases temperature at the stack.
5.1 VISUAL DIAGNOSTIC CONTROL BOX
The control box has a diagnostic function that can identify the likely causes of any malfunctions (indicator:
RED LED).
In order to be able to use this function, press and hold the reset button for at least 3 seconds from when the
appliance is made safe (lock-out).
The control box sends a sequence of pulses that are repeated at 2-second intervals.
The sequence of pulses issued by the control box identifies the possible types of malfunction, which are
listed in the table below.
SIGNAL PROBABLE CAUSE

6. FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for some problems that could cause a
failure to start or a bad working of the burner.
A fault usually makes the lock-out lamp light which is situated inside the reset button of the control box
(4, fig. 1, page 2).
When lock out lamp lights the burner will attempt to light only after pushing the reset button. After this if
the burner functions correctly, the lock-out can be attributed to a temporary fault.
If however the lock out continues the cause must be determined and the solution found.
6.1 START-UP PROBLEMS

6.2 OPERATING IRREGULARITIES
The burner locks out
during the prepurge
phase.
The air pressure switch does not
change over to the operational po-
sition.
The pressure switch is faulty, change it.
The air pressure is too low, (the head is
bad adjusted).
The flame exists. Faulty valves: replace them.
The pressure test point (13, fig. 9,
page 9) is badly positioned.
Place it in the right position according
to the instructions of this manual on
page 9, chapter 4.2.
The burner continues
to repeat the starting
cycle without going on
lock-out.
The gas pressure in the gas-mains
lies very close to the value to which
the gas pressure switch has been set.
The sudden falling-off pressure at the
opening of the valve causes the
opening of the pressure switch. How-
ever this only temporarily, because
the valve immediately closes again,
so then does the pressure switch, be-
cause the pressure builds-up again,
causing the cycle to be repeated
over and over.
Lower and set the pressure switch.
