IMPORTANT
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 efficiency at start up.
Normally the boiler's limit thermostat (TL) ensures the stopping of
the burner. If this is not the case, it is necessary to apply in series
with the (TL) a timer switch that turns off the burner at least once
every twenty-four hours.
TESTING
Check the burner has stopped by opening the hermostats.
Check that the burner has locked out during operation by opening
the connector (CN1) inserted in the probe's red wire, located out-
side the control box.

COMBUSTION HEAD ADJUSTMENT
Loosen 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 in a 40 kW boiler.
Considering efficiency of 90% the burner must
supply around 44 kW.
The diagram shows that for this
output the adjustment must be
made on notch 3.
The diagram is to be used only for
initial settings, to improve air pres-
sure switch operation or improve
combustion, it may be necessary to
reduce this setting (set point
toward position 0).
AIR DAMPER ADJUSTMENT
The air damper opening motor (1) controls the damper (6);
the burner does not start until the damper (6) is completely
open.
To adjust the fixed damper (4) it is necessary to:
loosen the screws (3 and 5) and rotate the damper as
far as the required point (2).
Once optimum adjustment has been reached, fix the
screws (3 and 5).
The adjustment of the damper varies in each single appli-
cation, so it is necessary to use a calibration tool to obtain
an efficient combustion result.
Important:
It is advisable to carry out an analysis of the combustion
values with the hood assembled.

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 by 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. It is advisable to set the burner according to the type of gas
used and following the indications of the table:
PROBE - ELECTRODE POSITIONING
IMPORTANT
Do not turn the starting electrode but leave it as shown in the drawing; if the starting electrode is put
near the ionization probe, the amplifier of the control box might be damaged.
IONISATION 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.
Should you want to measure the ionisation
current anyway, you must open the connec-
tor (CN1) (see wiring diagram page 5)
inserted in the red wire and insert a microammeter.

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
function at the required power, turn the knob slowly in a clockwise di-
rection until burner lockout.
Then turn the knob anticlockwise to an extent that is around 20% of
the adjusted value and then check that the burner starts up properly. If
the burner locks out again turn the knob slightly in an anticlockwise
direction.
Attention:
In conformity with the standard, the air pressure switch must prevent
the air pressure falling below 80% of the adjusted value and the CO in
the flue gases exceeding 1% (10,000 ppm). To check this, insert a
combustion analyser in the flue, slowly reduce the burner air setting
(for example with a piece of cardboard) and verify that the burner
locks out before the CO value in the flue gases exceeds 1%.

COLOUR CODE OF THE CONTROL BOX RESET BUTTON LED
(*) only for applications provided for.
RESET CONTROL BOX (FROM BUILT-IN BUTTON)
To reset the appliance proceed as follows:
Press the reset button for 1-2 seconds. If the burner fails to restart check that the limit thermostat (TL) is
closed.
Should the reset button of the appliance continue to flash showing the cause of failure (RED LED),
push the button for not more than 2 seconds.
Warning:
If the reset button is pressed for more than 2 seconds the appliance goes into the visual diagnostics phase and
the LED indicator begins to flash (see VISUAL DIAGNOSTICS CONTROL BOX).
RESET CONTROL BOX (FROM REMOTE CONNECTION)
The use of a connection available as an accessory is provided for the remote resetting of the control box.
RECYCLE FUNCTION (in case of disappearance of the flame during operation)
The control box permits a recycle, in other words the complete repetition of the start.-up programme, up to a max-
imum of 3 attempts in the case in which the flame goes out during operation.
If the flame goes out yet again ( 4th time) the burner goes into lockout. If there is a new heat request during recy-
cle , the 3 attempts are reset when the limit thermostat (TL) is switched.
LOGGING OF BURNER OPERATING PARAMETERS
With this control box, data - i.e. the number of lockout that have occurred, the type of lockout that has occurred
(just the last one) and the oil valve opening operating time - can be logged even when there is no power supply.
That way, you can determine how much fuel has been consumed during operation.
For the display of these parameters it is necessary to connect the diagnostic software kit as described on page
2.
ADDITIONAL, PROGRAMMABLE CONTROL BOX FUNCTIONS
POST-PURGING FUNCTION (t6)
Post-purging is a function that keeps air purging on even after the burner switches off. The burner switches off
when the limit thermostat (TL) opens, consequently 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 (burner switched off).
Post-purging time can be set to a maximum of 6 minutes, proceeding as follows:
Press and hold the reset button for at least 5 seconds till the LED indicator changes to red.
Set the desired time by pressing the button the appropriate times: once = post-purging for 1 minute.
After 5 seconds the control box automatically shows the minutes set by the red LED blinking: 1 led pulse =
post-purging for 1 minute.
To reset this function, press and hold the button for at least 5 seconds at least, till the LED indicator changes to red
then release it without carrying out any operation, then wait for 20 seconds for the burner to start again.
If during post-purging there is a new request for heat, post-purging time is halted and a new burner operating cy-
cle starts when the limit thermostat (TL) switches.
The control box's factory settings are as follows: 0 minutes = no post-purging.

CONTINUOUS PURGING FUNCTION, (only for applications in which this is provided for)
Continuous purging is an operation that maintains the air purging regardless of whether there is a request for the burner
to turn on or not. From the moment it is set, the motor keeps running whether the limit thermostat (TL) has not been
switched (burner off), or when the burner is blocked.
When the limit thermostat (TL) is switched, the motor stops for a standby time of 4 seconds (standby position = t2
+ t1), the air pressure switch is subsequently checked and a new burner operation cycle starts.
The function can be set from the reset button when the limit thermostat (TL) is not switched (burner off), by
following the procedure in the post-purging function paragraph pressing the button 7 times = continuous
purging.
To reset this function, press and hold the button for at least 5 seconds at least, till the LED indicator changes to red
then release it without carrying out any operation, then wait for 20 seconds for the burner to start again.
The control box's factory settings are as follows: 0 minutes = no continuous post-purging.
FUNCTION SETTING PROCEDURE USING RESET BUTTON
MAINTENANCE
Before cleaning or performing checks, switch off the burner’s power supply with the system’s master
switch and close the gas shutoff valve.
The burner requires periodic maintenance carried out by a qualified and authorised technician in conformity with
legislation and local standards.
Periodic maintenance is essential for the reliability of the burner, avoiding the excessive consumption of fuel and
consequent pollution.
THE BASIC OPERATIONS ARE: :
Checking that there are no obstructions or kinks in the supply or return oil pipes, in the air intake regions
and the combustion product discharge tubes.
Checking that the burner and gas train electrical connections are correct.
Checking that the gas train is suitable for the burner's power, the type of gas used and the mains gas pres-
sure.
Checking the proper positioning of the combustion head and its fixing to the boiler.
Checking the proper positioning of the air damper.
Checking the proper positioning of the ionisation probe and electrode.
Checking the adjustment of the air pressure switch and the gas pressure switch.
Let the burner work at full speed for approximately ten minutes, correctly adjusting all the elements indicated in
this manual. Then carry out the analysis of the scale combustion by checking:
Percentage of CO2(%); CO Content (ppm); NOx content (ppm);
Ionisation current (μA); Flue gases temperature at the flue;

VISUAL DIAGNOSTICS CONTROL BOX
The control box supplied features a diagnostics function through which any causes of malfunctioning can be
identified (indicator: RED LED signal).
To use this function, you must press and hold the reset button for at least 3 seconds once it has entered the
safety condition (lockout).
The control box generates a sequence of led pulses, which is repeated at constant 2-second intervals.
The sequence of led pulses issued by the control box identifies the possible types of malfunction, which are
listed in the table below.
To reset the control box after the diagnostics display, press the lockout-reset button.

FAULTS / SOLUTIONS
Here below you can find some causes and the possible solutions for a series of problems that could cause a
failure to start or the poor operation of the burner. A fault in the operation usually switches on the lockout lamp,
situated inside the reset button of the control box (7, 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. However, if lockout continues, you must determine the cause of the problem
and take the action illustrated in the tables below .
START-UP PROBLEMS

faulty. Check the connection or replace the mo- tor.
Burner runs normally in
the prepurge and igni-
tion cycle and locks out
after 5 seconds ca.
The phase-neutral connection is in-
verted Swap them over.
The wiring to the earth is lacking or
ineffective. Make earth connection efficient.
Ionisation probe has a ground fault
or is not in contact with flame, or
there is a break in its wiring to con-
trol box, or there is a ground fault
due to its insulation being defective.
Check right position and, if necessary,
adjust as indicated herein.
Restore electrical connection.

TROUBLE DURING OPERATION
The burner does not
pass through the pre-
purge and locks out.
The air pressure switch does not
switch
The pressure switch is defective; Re-
place it.
The air pressure is too low (combustion
head incorrectly set).
Flame is detected. Defective valves: replace them.
The burner continues
to repeat the starting
cycle without locking
out.
The gas pressure in the mains is
very near the value the gas pres-
sure switch is adjusted to. Conse-
quently, the sudden falling off in
pressure at the opening of the
valve causes the pressure switch
to open meaning the valves imme-
diately close and the motor stops.
The pressure then increases, the
pressure switch closes and the
starting cycle is started again, and
so on.
Reduce the pressure switch pressure
setting.
FAULTS POSSIBLE CAUSES SOLUTION
Burner locks out
during operation.
Probe has ground fault. Check right position and, if necessary,
adjust as indicated herein.
Clean or replace ionisation probe.
Flame disappears four times. Check gas mains pressure and/or adjust the solenoid valve, as indicated in this
manual.
Opening of the air pressure switch
The air pressure is too low (combustion
head incorrectly set).
The pressure switch is defective:
replace.
The burner stops. Opening of the gas pressure switch Check mains pressure and/or adjust the
solenoid valve as indicated in this
manual.

WARNINGS AND SAFETY
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.
You are therefore advised to consult the Technical Assistance Department before choosing this type of burner
for the combination with a boiler. Qualified personnel are those with the professional and technical require-
ments indicated by law no. 46 dated March 5, 1990.
The commercial organisation has a widespread network of agencies and technical offices whose personnel
participates periodically in instructional and refresher courses at the Company Training centre.
This burner must only be used for the purposes it has specifically been designed for.
All contractual and other liability on the part of the manufacturer is excluded for injury caused to people, ani-
mals or damage caused to property due to faulty installation, adjustment, maintenance or improper use.
BURNER IDENTIFICATION
The Identification Plate on the product gives the serial number, model and main technical and performance
data. Tampering with, removal or absence of the Identification Plate will mean it is not possible to identify the
product with certainty and therefore make any installation or maintenance difficult and/or dangerous.
BASIC SAFETY MEASURES
The control box may not be used by children or inexpert people.
Under no circumstances may intake grilles or heat dissipation grilles or the ventilation openings in rooms
where the control box is installed be plugged with rags, paper or anything else.
No attempt must be made to repair the control box by non-authorised personnel.
It is dangerous to twist or pull the electrical cables.
Under no circumstances must any attempt be made to carry out any cleaning operations before unplugging
the control box from the electrical supply.
Do not clean the control box or any of its parts with substances that can easily catch fire (e.g. petrol, alcohol,
etc.). The cover must be cleaned with soapy water.
Do not rest anything on the burner.
Do not plug or reduce the size of the ventilation openings in the room where the generator is installed.
Do not leave containers and inflammable substances in the room where the control box is installed.
WARNINGS TO AVOID BURNOUT OR BAD COMBUSTION OF THE BURNER
1 – When the burner is stopped, the flue must stay open 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 pipe
from the furnace. Before operating in this way take the voltage off.
2 – The premises the burner operates in must have same openings to allow the air necessary for com-
bustion to pass through. To be sure about this, you have to control CO2and CO in the exhaust
gases with all the windows and doors closed.
3 – If there are air intakes in the premises the burner works in make sure there are intakes big enough
to ensure the change required; In any case, check that when the burner stops the extractors do not
draw hot fumes from pipes through the burner.
