CARRIED-OUT
IN THE FACTORY
ATTENTION:
Do not swap neutral and phase over, follow the diagram shown carefully and carry out a good earth connection.
The section of the conductors must be at least 1mm. (Unless requested otherwise by local standards and legislation).
The electrical wiring carried out by the installer must be in compliance with the rules in force in the country.
Verify that the burner stops by operating the boiler control thermostats and that the burner locks out by separating
the red ionisation probe lead connector.
NOTES
The burners have been type-approved for intermittent operation. 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 se-
ries 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 car-
ried 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 set-
ting of the combustion head, and the air damper opening.
4.2 COMBUSTION HEAD SETTING
Loose the screw (A), move the elbow (B) so that the rear plate
of the coupling (C) coincides with the set point.
Tighten the screw (A).
Example:
The burner is installed on a 155 kW boiler
with an efficiency of 90%, the burner
input is about 172 kW using the diagram,
the combustion set point is 3.
The diagram is to be used only for initial
settings, to improve air pressure switch
operation or improve combustion, it may
be necessary to reduce this setting (set
point toward position 0).

4.3 AIR DAMPER SETTING
The regulation of the air-rate is made by adjusting the air damper (1), after
loosing the screws (2).
When the optimal regulation is reached, screw tight the screws (2).
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 control box operation is 3 μA.
The burner normally supplies a higher current value, so that no check is needed. However, if you want to measure
the ionization current, you must open the connector fitted to the red 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 minimum 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 EN 676 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 ver-
ify that the burner shuts down by the action of the air pressure switch before the CO value exceeds 1%.

4.8 RESETTING THE CONTROL BOX AND USING DIAGNOSTICS
The control box features a diagnostics function through which any causes of malfunctioning are easily identi-
fied (indicator: RED LED).
To use this function, you must wait at least 10 seconds once it has entered the safety condition (lock-out),
and then press the reset button.
The control box generates a sequence of pulses (1 second apart), which is repeated at constant 3-second
intervals.
Once you have seen how many times the light pulses and identified the possible cause, the system must be
reset by holding the button down for between 1 and 3 seconds.
The methods that can be used to reset the control box and use diagnostics are given below.
RESETTING THE CONTROL BOX
To reset the control box, proceed as follows:
Hold the button down for between 1 and 3 seconds.
The burner restarts after a 2-second pause once the button is released.
If the burner does not restart, you must make sure the limit thermostat is closed.
VISUAL DIAGNOSTICS
Indicates the type of burner malfunction causing lock-out.
To view diagnostics, proceed as follows:
Hold the button down for more than 3 seconds once the red LED (burner lock-out) remains steadily lit.
A yellow light pulses to tell you the operation is done.
Release the button once the light pulses. The number of times it pulses tells you the cause of the malfunc-
tion, indicated in the table below.
SOFTWARE DIAGNOSTICS
Reports the life of the burner by means of an optical link with the PC, indicating hours of operation, number
and type of lock-outs, serial number of control box etc ...
To view diagnostics, proceed as follows:
Hold the button down for more than 3 seconds once the red LED (burner lock-out) remains steadily lit.
A yellow light pulses to tell you the operation is done.
Release the button for 1 second and then press again for over 3 seconds until the yellow light pulses
again.
Once the button is released, the red LED will flash intermittently with a higher frequency: only now can the
optical link be activated.
Once the operations are done, the control box’s initial state must be restored using the resetting procedure
described above.
BUTTON PRESSED FOR CONTROL BOX STATUS

5. WARNINGS TO AVOID BURNOUT OR BAD COMBUSTION OF THE BURNER
1– When the burner is stopped, the smoke pipe must be opened and effect a natural draught 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 operating in this way take the voltage off.
2– The place, where the burner works, must have same openings suitable for the passage of air necessary
for combustion. To be sure about this, you have to control CO2and CO in the exhaust gases with
all the windows and doors closed.
3– If in the place, where the burner works, there are air-breathings, check the existence of air-input
openings with dimensions suitable for the necessary air-exchange. In any case check that, when the
burner is stopped, the air-breathings do not draw warm smokes from pipes through the burner.
6. MAINTENANCE
The burner requires periodic maintenance carried out by a qualified and authorised technician in conformity
with legislation and local standards.
Maintenance is essential for the reliability of the burner, avoiding the excessive consumption of fuel and con-
sequent pollution.
Before carrying out any cleaning or control always first switch off the electrical supply to the burn-
er acting on the main switch of the system.
THE BASIC CHECKS ARE:
Leave the burner working without interruption for 10 min., checking the right settings of all the components
stated in this manual. Then carry out a combustion check verifying:
CO2(%) content Smoke temperature at the chimney CO content (ppm).

7. FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for some problems that could cause a fail-
ure 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 (9, fig. 1, page 1).
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.

测试锅炉
负荷图依据 EN676 标准测试得到。
商用锅炉
如果锅炉的设计和制造符合 EN303 标准，并且炉膛尺寸与 EN676 标准中的图表尺寸接近，那么燃烧器 - 锅炉匹配
没问题。
如果锅炉的设计和制造不符合 EN303 标准或者炉膛尺寸大大小于 EN676 标准中的图表尺寸，请咨询生产商。
燃气压力与燃烧器出力的关系
用净热值为 10KWh/m3 （8.570kcal/m3）的 G20 燃气进行测试，在锅炉背压为 0mbar，燃烧器出力最大时，燃烧
头处测量压力为 5.8mbar(M2，见第 4 页，章节 3.3)。
