GENERAL STANDARDS
This manual is an integral and essential part of the product and must be given to the
installer.
Read the warnings given in this manual as they supply important indications regarding
instal-lation, use and maintenance safety.Keep this manual carefully for future referen-
ce. The burner must be installed in compliance with the Standards in force, according
to the manufacturer’s instructions and by qualied staff Incorrect installation can cause
injury/damage to persons, animals or objects, for which the manufacturer cannot be
held responsible.
This appliance must only be destined for the use for which it was expressly declared.
Any other use must be considered improper and therefore dangerous.The manufactu-
rer is not liable for any damage caused by improper, incorrect or unreasonable use.
Before carrying out any cleaning or maintenance, disconnect the appliance from the
mains power supply by acting on the system switch or via the relevant shut-off ele-
ments.
In the case of breakdown and/or bad functioning of the appliance, deactivate it and do
not at-tempt repairs or direct interventions.
Only contact qualied professional staff.Any product repairs must only be performed
by an after-sales centre authorised by the manufacturer, using original spare parts.Fai-
lure to comply with the above can compromise appliance safety.In order to guarantee
the efciency of the appliance and its correct functioning, it is indispen-sable to follow
the manufacturer’s indications.
Have qualied professional staff perform periodic maintenance of the appliance.Whe-
never the appliance is no longer to be used, the parts that may become a potential
source of danger must be made harmless.
Before commissioning the burner, have qualied staff check:a) that the plate data are
those requested by the gas electricity mains supplies;b) that burner calibration is com-
patible with boiler power;c) that the ow of combustion agent air and the evacuation
of ue gases take place correctly according to Standards in force;d) that aeration and
normal maintenance of the burner are guaranteed.
Before performing any intervention that envisions disassembly of the burner or ope-
ning of the inspection access points, disconnect the electric current.
Do not deposit containers of inammable substances in the room where the burner is
situa-ted.

26
UK
The burner room must have openings towards the outside in compliance with local
Standards in force. If in doubt relative to the circulation of air, rst of all we recommend
that the CO2 value is measured, with the burner functioning at maximum ow rate and
the room ventilated, only via the apertures destined to feed air to the burner andthen
by measuring the CO2 value again, with the door open.The value of CO2 measured in
both cases must not change in a signicant manner.If there are more than one burner
and fan in the same room, this test must be performed with all appliances functioning
simultaneously.
Never obstruct the air apertures of the burner room, the burner fan intake apertures
and any air duct or ventilation grid and external dissipations, with the purpose of pre-
venting:- the formation of toxic/explosive gas mixtures in the air of the burner room;-
combustion with insufcient air, from which dangerous, costly and polluting functioning
oc-curs.
The burner must always be protected from rain, snow and freezing.
The burner room must always be kept clean and free from volatile substances, which
could be sucked inside the fan and block the interior pipes of the burner and the com-
bustion head. Dust is extremely dangerous, especially if this can deposit on the fan
blades, where it will reduce ventilation and produce pollution during combustion. The-
dust an also accumulate on the rear part of the ame stability disc in the combustion
head and cause a poor air/fuel mixture.
The burner must be fed with the type of fuel for which it has been set-up as indicated
on the data plate and in the technical features supplied in this manual. Moreover, it
must be supplied with all control and safety devices requested by local regulations in
force. Pay great care that no external material enters the line during installation.
Make sure that the electric power supply used for the connection is in compliance with
the features indicated on the data plate and in this manual.Make an electric plant with
an effective connection to an earth plant, in compliance with Standards in force. The
earth cable must be a couple of cm. longer that the phase and neutral wire.
If in doubt regarding efciency, it must be checked and controlled by qualied staff.
Never ex-change the neutral and phase cables.The burner can be connected to the
mains electricity with a plug-socket connection only if this is equipped in a way that the
coupling conguration prevents the inversion of phase and neutral.Install an omnipo-
larswitch with opening between contacts of at least 3mm upstream from the appliance
as reque-sted by the existing legislation.
The entire electric system and in particular all cable sections, must be suitable for the
maxi-mum absorbed power value indicated on the appliance data plate and in this
manual.
If the burner power supply cable is faulty, it must only be replaced by qualied staff.

27
UK
Never touch the burner with wet body parts or without wearing shoes.
Never stretch (force) power supply cables and keep them away from heat sources.The
length of the cables used must allow the burner and any boiler door to be opened.
The electric connections must be made exclusively by qualied staff and the regula-
tions in force on the subject of electricity must be respected.After all packaging ma-
terial has been re moved, control the contents and ensure that these have not been
damaged in any way during transport.
If in doubt, do not use the burner and contact the supplier.
The packaging materials (wooden cages, cardboard, plastic bags, expanded mate-
rials, sta-ples, etc...) represent a form of pollution and potential risk if left everywhere.
Collect them and dispose of them in a suitable manner (in a suitable place).

PUMP PRESSURE ADJUSTMENT
The pump pressure is pre-set during production at 12 bar.For controlling pressure use an oil
bathed manometer.
The pressure can be adjusted from 11 to 14 bar. From 7 to 14 bar for model R.
The pump is preadjusted at the factory to 10 bar for the 1st stage and 18 bar for the
2nd stage.Use an oil-bath pressure gauge to check the pressure.The recommended
operating pressure is between 10 and 20 bar.

The geared motor limit switch and auxiliary contacts are triggered by easily accessible
adju-stable cams, which can be set against o graduated scale
SETTING THE CONTACT TRIGGERING POINT
General information:
CAM V (2 Stage) - Cam controlling air valve fully open position (maz. ring rate with
both stages in operation).
CAM IV (1 Stage) - Cam controlling minimum air ow condition (min. ring rate 1st
stage only in operation).
CAM II-III (MV1-MV2) - Auxiliari cam activating the 2nd stage valve.
RECOMMENDATIONS TO PROPERLY SET THE GEARED MOTOR
The geared motor is set upon testing as follows:
CAM V (2 Stage) : is set on approx 90°-120°
CAM IV (1 Stage) : is set on approx 25°÷50°.
CAM II-III (MV1-MV2): is set in such a way that the 2nd stage valve opens when the air
shut-off valve is at 60°÷80°.
Changes to this calibration during installation are legible even when the burner is in
operation by acting on the adjusting screws of the cams.
Tightening the screws increases the angle and positioning of the cams.

Most components can be checked by removing the cover. For head inspection, the compo-
nent plate must be dismounted which can be hung on the burner body in 2 positions to allow
intervention in the most rationable way. The motor, transformer and electromagnetic valve
are electronically connected to plug/socket, thephotoresistance is inserted under pressure.
ATTENTION:ensure unit is unplugged before removing cover.
Fig. A
By removing the cover, access is gained
to:condensor-motor, control box, transfor-
mer photoresistance, pump, electroma-
gnetic valve.
Fig. B
By unscrewing the plate xing pin the burner
can be opened allowing
access to the fan, nozzle, electrodes and
preheater..
In order to obtain the best combustion performance and efciency, and for respect of the envi-
ronment, checksand adjustment of the combustion must be carried out, and with appropriate
tools.Basic values to be considered are:
—CO2 indicates the amount of excess air during combustion; if air is increased, CO2 % value-
sdecrease, and if combustion air is decreased, CO2 % values increase.
—SMOKE SCALE (Bacharach) indicates that solid un-burnt particles are present in the smo-
ke. If N°2 on the BH scale is exceeded the nozzle must be checked for faults and that it is
adapt to the burnerand boiler (trade, type, pulverization angle).Usually the BH scale number
tends to decrease, increasing pump pressure, in this case keep theincreasing combustion
levels under control.
—SMOKE TEMPERATURE is a level which indicates heat loss through the chimney; higher
thetemperature, greater is the loss and lower combustion efciency. If the temperature is too
high thequantity of burned light oil needs to be lowered.
IMPORTANT: existing laws in some countries can require a different adjustment to that given
here and may alsohave different parameters. ECO burners are designed to meet the toughest
international laws on energy savingand respect of the environment.
