Safety and prevention
3.1 Introduction
The burners have been designed and built in compliance with
current regulations and directives, applying the known technical
rules of safety and envisaging all the potential danger situations.
It is necessary, however, to bear in mind that the imprudent and
clumsy use of the equipment may lead to situations of death risk
for the user or third parties, as well as the damaging of the burner
or other items. Inattention, thoughtlessness and excessive confi-
dence often cause accidents; the same applies to tiredness and
sleepiness.
It is a good idea to remember the following:
The burner must only be used as expressly described. Any
other use should be considered improper and therefore dan-
gerous.
In particular:
it can be applied to boilers operating with water, steam, diather-
mic oil, and to other uses expressly named by the manufacturer;
the type and pressure of the fuel, the voltage and frequency of the
electrical power supply, the minimum and maximum deliveries for
which the burner has been regulated, the pressurisation of the
combustion chamber, the dimensions of the combustion cham-
ber and the room temperature must all be within the values indi-
cated in the instruction manual.
Modification of the burner to alter its performance and desti-
nations is not allowed.
The burner must be used in exemplary technical safety con-
ditions. Any disturbances that could compromise safety must
be quickly eliminated.
Opening or tampering with the burner components is not
allowed, apart from the parts requiring maintenance.
Only those parts envisaged by the manufacturer can be
replaced.
3.2 Personnel training
The user is the person, body or company that has acquired the
machine and intends to use it for the specific purpose. He is re-
sponsible for the machine and for the training of the people work-
ing around it.
The user:
undertakes to entrust the machine exclusively to suitably
trained and qualified personnel;
undertakes to inform his personnel in a suitable way about
the application and observance of the safety instructions.
With that aim, he undertakes to ensure that everyone knows
the use and safety instructions for his own duties;
Personnel must observe all the danger and caution indica-
tions shown on the machine.
Personnel must not carry out, on their own initiative, opera-
tions or interventions that are not within their province.
Personnel must inform their superiors of every problem or
dangerous situation that may arise.
The assembly of parts of other makes, or any modifications,
can alter the characteristics of the machine and hence com-
promise operating safety. The manufacturer therefore
declines any and every responsibility for any damage that
may be caused by the use of non-original parts.
In addition:
3 Safety and prevention
WARNING
The manufacturer guarantees safety and proper
functioning only if all burner components are intact
and positioned correctly.
the user must take all the measures neces-
sary to prevent unauthorised people gaining
access to the machine;
the user must inform the manufacturer if
faults or malfunctioning of the accident pre-
vention systems are noticed, along with any
presumed danger situation.
Personnel must always use the personal pro-
tective equipment envisaged by legislation
and follow the indications given in this man-
ual.

4.5 Firing rate
The MAXIMUM OUTPUT is chosen from within the diagram area
(Fig. 3).
The MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram.
The burner delivery must be selected within area of the diagrams
(Fig. 3). This area is called firing rate and provides the maximum
delivery of the burner in relation to the pressure in the combustion
chamber.
The work point may be found by plotting a vertical line from the
desired delivery and a horizontal line from the pressure in the
combustion chamber. The intersection of these two lines is the
work point which must lie within the firing rates.

5 Installation
DANGER
All the installation, maintenance and disassembly
operations must be carried out with the electricity
supply disconnected.
WARNING
The installation of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.
WARNING
The handling operations for the burner can be
highly dangerous if not carried out with the great-
est attention: keep any unauthorised people at a
distance; check the integrity and suitableness of
the available means of handling.
Check also that the area in which you are working
is empty and that there is an adequate escape
area (i.e. a free, safe area to which you can quick-
ly move if the burner should fall).
When handling, keep the load at not more than
20-25 cm from the ground.
CAUTION
After positioning the burner near the installation
point, correctly dispose of all residual packaging,
separating the various types of material.
Before proceeding with the installation operations,
carefully clean all around the area where the burn-
er will be installed.
CAUTION
After removing all the packaging, check the integ-
rity of the contents. In the event of doubt, do not
use the burner; contact the supplier.
The packaging elements (wooden cage or card-
board box, nails, clips, plastic bags, etc.) must not
be abandoned as they are potential sources of
danger and pollution; they should be collected and
disposed of in the appropriate places.
S8585 Fig. 4
WARNING
The output of the burner must be within the
boiler's firing rate;
WARNING
A burner label that has been tampered with, re-
moved or is missing, along with anything else that
prevents the definite identification of the burner
makes any installation or maintenance work diffi-
cult.

The burner is designed to allow entry of the hoses-lines on
either side of the burner.
6.2.1 Pump
The pump is designed to allow working with two pipes.
In order to obtain one pipe working it is necessary to unscrew the
return hose, remove the by-pass screw 3) and then screw the re-
turn plug 2).

WARNING
Where at all possible avoid the use of two pipe
systems where the circulated fuel is returned to
the tank.
If this cannot be avoided make sure that the return
pipe is normally below the surface of the fuel level
within the storage tank. See Fig. 11.
WARNING
The suction plug 1) is made of plastic. Once re-
moved, it must not be used again.
In single pipe installations, the plug in the return
line 2) must be totally in steel.
DANGER
It is strongly recommended a periodic check of
the pump pressure operation (annually or better
every six months, if the burner operation is contin-
uous).
If the value is lower than 1 bar, compared to that
one of the initial setting, please check the cleaning
of the pump and line filters.
In case the pressure setting was not restorable,
please replace the pump, in order to guarantee
that the pump pressure during the pre-purge time
is at least 3.7 bar.

Hydraulic systems
6.3 Two pipe system
Vacuum two pipe systems (Fig. 11) have a negative fuel pres-
sure (depression) on intake to the burner.
Usually the tank is lower than the burner.
The return line should terminate in the oil tank at the same level
as the suction line; in this case a non-return valve is not required.
Should however the return line arrives over the fuel level, the
non-return valve is indispensable. This solution however is less
safe than previous one, due to the possibility of leakage of the
valve.
6.3.1 Priming pump
On the system in Fig. 11 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least
20 seconds before repeating the operation.

WARNING
Before starting the burner make sure that the re-
turn pipe-line is not clogged: any obstruction
would cause the pump seals to break.
WARNING
The pump vacuum should not exceed a maximum
of 0.4 bar (30 cm Hg).
Beyond this limit gas is released from the oil. H

6.4 One pipe system
Pressurised one pipe systems (Fig. 12) have a positive fuel pres-
sure on intake to the burner.
Usually the tank is higher than the burner, or the fuel pumping
systems are on the outside of the boiler.
Vacuum one pipe systems (Fig. 13) have a negative fuel pres-
sure (depression) on intake to the burner.
Usually the tank is lower than the burner.
6.4.1 Priming pump
On the system in Fig. 12 it is sufficient to loosen the plug of the
vacuum gauge 6)(Fig. 10) and wait until the fuel flows out.
On the system in Fig. 13 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least
20 seconds before repeating the operation.

7.1 Notes on safety for the electrical wiring
Before carrying out any maintenance, cleaning or checking oper-
ations:
If the cover is still present, remove it and proceed with the electri-
cal wiring according to the wiring diagrams.
Use flexible cables in compliance with the EN 60 335-1 standard.
7 Electrical system
DANGER
The electrical wiring must be carried out with the electrical supply disconnected.
Electrical wiring must be carried out by qualified personnel and in compliance with the regulations currently in
force in the country of destination. Refer to the wiring diagrams.
The manufacturer declines all responsibility for modifications or connections different from those shown in the
wiring diagrams.
Do not invert the neutral with the phase in the electrical supply line. Any inversion would cause a lockout due to
firing failure.
Check that the electrical supply of the burner corresponds to that shown on the identification label and in this
manual.
The burners have been set for intermittent operation. This means they should compulsorily be stopped at least
once every 24 hours to enable the control box to perform checks of its own start-up efficiency. Normally the
boiler's thermostat/pressure switch ensures the stopping of the burner.
If this is not the case, it is necessary to apply in series with IN a timer switch that turns off the burner at least once
every twenty-four hours. Refer to the wiring diagrams.
The electrical safety of the device is obtained only when it is correctly connected to an efficient earthing system,
made according to current standards. It is necessary to check this fundamental safety requirement. In the event
of doubt, have the electrical system checked by qualified personnel.
The electrical system must be suitable for the maximum input power of the device, as indicated on the label and
in the manual, checking in particular that the section of the cables is suitable for the input power of the device.
For the main power supply of the device from the electricity mains:
- do not use adapters, multiple sockets or extensions;
- use an omnipolar switch, as indicated by the current safety standards.
Do not touch the device with wet or damp body parts and/or in bare feet.
Do not pull the electric cables.
DANGER
disconnect the electrical supply from the burner by
means of the main system switch;
DANGER
isolate the fuel supply.
DANGER
Condensation, water infiltration and formation of
ice are not permitted!
After carrying out maintenance, cleaning or
checking operations, reassemble the cover and

Start-up, calibration and operation of the burner
8.1 Notes on safety for the first start-up
8.2 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, fit the nozzle then adjust
the pump pressure and the air damper opening in accordance
with the Tab. E.
The values shown in the table are measured on a CEN boiler (as
per EN 267).
They refer to 12.5% CO2at sea level and with light oil and room
temperature of 20°C.
Tab. E
8.2.1 Nozzles reccomended
Monarch type R
Delavan type W - E
Steinen type Q
Danfoss type S
Satronic type S
The burner complies with the emission requirements of the
EN 267 standard.
In order to guarantee that emissions do not vary, recommended
and/or alternative nozzles specified by themanufacturer in the In-
struction and warning booklet should be used.
8.2.2 Combustion head setting
This is done when fitting the nozzle, with the blast tube removed.
It depends on the output of the burner and is carried out by rotat-
ing the regulating rod, till the terminal plane of the blast tube is
level with the set-point, as indicated in the schedule.
For this application, the head should be fully open (at notch 6).
8 Start-up, calibration and operation of the burner
WARNING
The first start-up of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.

WARNING
It is advisable to replace nozzles every year
during regular maintenance operations.
CAUTION
The use of nozzles other than those specified by
the manufacturer and inadequate regular mainte-
nance may result into emission limits non-con-
forming to the values set forth by the regulations
in force, and in extremely serious cases, into po-
tential hazards to people and objects.
The manufacturing company shall not be liable for
any such damage arising from nonobservance of
the requirements contained in this manual.

Start-up, calibration and operation of the burner
Combustion head settings indicated in the schedule are valid for
most cases.
The setting of the fan output according to the installation should
normally be done only through the air damper. Should one sub-
sequently want to retouch also the setting of the combustion
head, with the burner running, operate on the rod (1) with a 6 mm
spanner (2) as follows:
Turn to the right: (Sign +)
In order to increase the volume of air entering the combustion
chamber and thus diminishing its pressure. There is a reduction
of CO2 and the adhesion of the flame to the air diffuser disc im-
proves.
(Setting advisable for ignitions at low temperatures).
Turn to the left: (Sign –)
In order to reduce the volume of air entering the combustion
chamber and thus increasing its pressure. The CO2 improves
and the adhesion of the flame to the diffuser tends to reduce.
(This setting is not advisable for ignitions at low temperatures).
In any case do not bring the combustion head setting more than
one point away from that indicated in the schedule. One set-point
corresponds to 3 turns of the rod; a hole (3) at its end facilitates
counting the number of turns.
8.2.3 Air damper adjustment
The settings indicated in the schedule refer to the burner with its
metal cover fitted and the combustion chamber with “zero”de-
pression. These regulations are purely indicative. Each installa-
tion however, has its own unpredictable working conditions:
actual nozzle output; positive or negative pressure in the com-
bustion-chamber, the need of excess air,etc. All these conditions
may require a different air-damper setting.
Therefore we recommended to proceed as follows:
adjust the air damper as indicated in the Tab. E to page 17;
mount the cover, simply by means of the upper screw;
check smoke number;
should it become necessary to modify the air output,
remove the cover by loosening the screw, adjust the air
damper, remount the cover and finally recheck the smoke
number.

WARNING
It is important to take account of the fact that the
air output of the fan differs according to whether
the burner has its metal cover fitted or not.
