CARRIED-OUT
IN THE FACTORY
³Do not swap neutral and phase over, follow the diagram shown carefully and carry out a good earth
connection.
³The section of the conductors must be at least 1mm². (Unless requested otherwise by local standards and leg-
islation).
³The electrical wiring carried out by the installer must be in compliance with the rules in force in the country.
³Verify 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 series to limit thermostat (TL).

4.2 Air damper setting
The regulation of the air-rate is made by adjusting the air damper (1)
Fig. 11, after loosing the screws (2).
When the optimal regulation is reached, screw tight the screws (2).
4.3 Combustion check
CO2It is advisable to not exceed 10% of CO2(natural gas), in order
to avoid the risk that small changes of the adjustments due, for
instance, at draught variation, may cause combustion with
insufficient air and consequently formation of CO.
CO Not exceeding 100 mg/kWh (93 ppm).
IONIZATION CURRENT
The minimum current necessary for the
control box operation is 3 µA.
The burner normally supplies a higher cur-
rent value, so that no check is needed.
However, if you want to measure the ioni-
zation current, you must open the
connector fitted to the red wire and insert a
microammeter.

4.5 Start-up cycle diagnostics
During start-up, indication is according to the followin table:
4.6 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 blinks (1 second apart), which is repeated at constant 3-second
intervals.
Once you have seen how many times the light blinks 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:
³Hold 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:
³Hold the button down for more than 3 seconds once the red LED (burner lock-out) remains steadily lit.
A yellow light blinks to tell you the operation is done.
Release the button once the light blinks. The number of times it blinks 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:
³Hold the button down for more than 3 seconds once the red LED (burner lock-out) remains steadily lit.
A yellow light blinks 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 blinks again.
Once the button is released, the red LED will flash intermittently with a higher frequency: only now can the
optical link be activated.

5 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).
6 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.
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.

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.
7.2 Basic safety measures
³Children or inexpert persons must not use the appliance.
³Under 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.
³Unauthorised persons must not attempt to repair the appliance.
³It is dangerous to pull or twist the electric leads.
³Cleaning operations must not be performed if the appliance is not disconnected from the main power supply.
³Do not clean the burner or its parts with inflammable substances (e.g. petrol, alcohol, etc.). The cover
must be cleaned with soapy water.
³Do not place anything on the burner.
³Do not block or reduce the size of the ventilation vents in the installation room.
³Do not leave containers and inflammable products in the installation room.
