ity for the failure to observe the contents of this manual.
The warranty is subject to correct burner, appliance & application
matching and set-up in line with EOGB’s instructions and guide-
lines.. All components within the hydraulic circuit suitable for bio
fuel use and supplied by EOGB will be identied as bio compatible.
No warranty is given in relation to the use of components which
are not so identied with biofuel blends. If in any doubt please
contact EOGB for further advice.
If any EOGB burners are used with fuel with a bio content >10%then
the components within the hydraulic circuit may be aected and
are not covered under warranty.
The hydraulic circuit consists of:
• Pump
• Hydraulic ram (where applicable)
• Valve block
• Flexible oil lines (considered as a consumable
component)
1 Irrespective of any warranty given by EOGB in relation to
normal use and manufacturing defects, when fuels not meeting
the relevant standards are used, or where fuel storage issues have
not been addressed correctly, or the equipment used is not com-
patible, if failures occur which are directly or indirectly attributed to
such issues and/or to the non-observance of this guidance, then
no warranty or liability is implied or accepted by EOGB.
2 EOGB have carefully chosen the specication of the bio
compatible components including the exible oil lines to protect
the pump, safety value and nozzle. The EOGB warranty is depend-
ent upon the use of EOGB genuine components, including the oil
lines, being used.
3 EOGB warranty does not cover defects arising from incor-
rect commissioning or servicing by non-EOGB employed service
engineers, and any issues impacting the burner arising from
external site-related issues.
2.3 Guidance for the use of biofuel blends up to 10% where gas oil use is permitted by the appliance manufacture
Background
With increasing focus on renewable and sustainable energy re-
quirements, Biofuel usage is set to increase. EOGB is committed to
promoting energy conservation and the use of renewable energy
from sustainable resources including liquid biofuels; however there
are some technical aspects that must be considered at the plan-
ning stage of using such fuels to reduce the potential for equip-
ment failure or the risks of fuel leakage.
Liquid biofuel is a generic description used for oil that can come
from numerous feed stocks including recycled cooking oils. These
types of oils have to be considered and treated dierently from
standard mineral or fossil fuels, as they are generally more
acidic, hydroscopic and less stable.
Due to this, a holistic approach is needed from the specication
of the liquid biofuel, the storage of the fuel, its oil supply line and
ancillary equipment, and very importantly the oil ltration and the
burner itself. The specication for FAME (Fatty Acids Methyl Ester)
liquid biofuel is critical to reliable equipment operation.
It is a minimum requirement that the fuel blend (up to 10% bio) is
obtained with gas oil in accordance with the relevant EN stand-
ards, regional regulations and FAME in accordance with EN 14214.
It is also important that the fuel blends meet the requirements
related to operational environment conditions within the relevant
EN standards.
When choosing your EOGB oil products where you know biofuels
will be in use, please make sure that a bio compatible burner
and/or components have been supplied. If an existing burner
is to be used with a liquid biofuel then a kit may be required to
make it compatible and the guidance notes enclosed concern-
ing oil storage and ltration must be adhered to. The end user is
responsible for the thorough verication of the potential risks asso-
ciated with the introduction of a bio fuel blend and the suitability
of the appliances and installation applicable.
Irrespective of any warranty given by EOGB in relation to normal
use and manufacturing defects, when fuels not meeting the rel-
evant standards are used, or where fuel storage issues have not
been addressed correctly, or the equipment used is not compat-
ible, if failures occur which are directly or indirectly attributed to
such issues and/or to the non-observance of this guidance, then
no warranty or liability is implied or accepted by EOGB.

Information and general warnings
2.3.1 Information and general instructions
To ensure consistency, the supplier of the fuel must be able to
demonstrate compliance with a recognised Quality Control and
management system to ensure high standards are maintained
within the storage, blending and delivery processes.
The installation of an oil storage tank and its ancillaries must also
be prepared BEFORE liquid biofuel is introduced.
Checks and preparation should include:
• For new installations, make sure that all materials and
seals in the oil storage and supply line to the burner are compati-
ble with biofuels. For all installations, there must be a good quality
bio compatible oil lter at the tank and then a secondary lter of 60
Microns protecting the burner from contamination.
• If an existing oil storage tank is to be used then in addition
to the materials checks as detailed above, it will be essential that
the tank is rst inspected for condition and checked for water or
other contamination. EOGB strongly recommends that the tank is
cleaned and oil lters replaced prior to biofuel delivery. Due to the
hydroscopic nature of biofuel, if this is not completed then it will
eectively clean the tank and absorb water present which in turn
will result in equipment failure that is not covered by the manufac-
turer’s warranty.
• Depending on the capacity of the oil storage tank and
oil usage, fuels may remain static within the tank for some consid-
erable time and so EOGB recommends that the oil distributor is
consulted regarding the use of additional Biocides within the fuel
to prevent microbial growth from occurring within the tank. EOGB
suggests that fuel suppliers and/or service companies are con-
tacted for guidance on fuel ltration. Special attention should be
applied to dual fuel applications where oil may be stored for long
periods of time.
• The burner must be set according to the appliance appli-
cation and commissioned checking that all combustion parame-
ters are as recommended in the appliance technical manual.
• EOGB recommends that the in line and burner oil pump
lters are inspected and if required replaced at least every 4
months during burner use, before the burner start-up following a
long period of discontinue operation and even more frequently
where contamination has occurred. Particular attention is needed
when inspecting and checking for fuel leakages from seals, gas-
kets and hoses.

Safety and prevention
3 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 damage to the burner
or other items. Inattention, thoughtlessness and excessive con-
dence oen cause accidents.
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
dangerous.
In particular:
it can be applied to boilers operating with water, steam,
thermic 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 chamber
and the room temperature must all be within the values indicated
in the instruction manual.
• Modication of the burner to alter its performance and
destinations is not allowed.
• The burner must be used in technically safe working
conditions. 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 detailed as available as spare parts by
the manufacturer can be replaced.
3.2 Safety warnings
The dimension of the boiler’s combustion chamber must respond
to specic values in order to guarantee a combustion with the
lowest polluting emissions rate.
The Technical Service Personnel will be glad to give you all the infor-
mation for a correct matching of this burner to the boiler.
This burner must only be used for the application it was designed
for.
The manufacturer accepts no liability within or without the con-
tract for any damage caused to people, animals and property
due to installation, adjustment and maintenance errors or to
improper use.
3.3 Basic safety rules
• Children or inexpert persons must not use the appliance.
• Under 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.
• Unauthorised persons must not attempt to repair the
appliance.
• It is dangerous to pull or twist the electric leads.
• Cleaning operations must not be performed if the appli-
ance is not disconnected from the main power supply.
• Do not clean the burner or its parts with inammable
substances (e.g. petrol, alcohol, etc.). The cover must be cleaned
with soapy water.
• Do not place anything on the burner.
• Do not block or reduce the size of the ventilation vents in
the installation room.
• Do not leave containers and inammable products or
combustible materials in the installation room.
3.4 Personnel training
The user is the person, body or company that has acquired the
machine and intends to use it for the specic purpose. He is
responsible for the machine and for the training of the people
working around it.
The user:
• undertakes to entrust the machine exclusively to suitably
trained and qualied personnel;
• must take all the measures necessary to prevent unau-
thorised people gaining access to the machine;
• 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;
• must inform the manufacturer if faults or malfunctioning
of the accident prevention systems are noticed, along with any
presumed danger situation.
• Personnel must always use the personal protective
equipment envisaged by legislation and follow the indications
given in this manual.
• Personnel must observe all the danger and caution
indications shown on the machine.
• Personnel must not carry out, on their own initiative,
operations or interventions that are not permitted within their local
authority control.
• Personnel must inform their superiors of every problem or
dangerous situation that may arise.
• The assembly of parts of other makes, or any modica-
tions, can alter the characteristics of the machine and hence
compromise operating safety. The manufacturer therefore de-
clines any and every responsibility for any damage that may be
caused by the use of non-original parts.

Installation
5.1 Notes on safety for the installation
Aer carefully cleaning all around the area where the burn-
er will be installed, and arranging the correct lighting of the
environment, proceed with the installation operations.
All the installation, maintenance and disassembly
operations must be carried out with the electricity
supply disconnected.
The installation of the burner must be carried out
by qualied personnel, as indicated in this manual
and in compliance with the standards/regulations
and local authority legislation.
WARNING
DANGER
5.2 Handling
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
quickly move if the burner should fall).
Aer positioning the burner near the installation
point, correctly dispose of all residual packaging,
separating the various types of material.
Before proceeding with the installation opera-
tions, carefully clean all around the area where
the burner will be installed.
CAUTION
WARNING
5.3 Preliminary checks
Aer removing all the packaging, check the
integrity 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
manner and location.
Checking the consignment
Checking the characteristics of the burner
The output of the burner must be within the
boiler’s ring rate.
A burner label that has been tampered with,
removed or is missing, along with anything else
that prevents the denite identication of the
burner makes any installation or maintenance
work dicult.

Installation
5.4 Installer/service notes for the use of gas oil with bio blends up to 10% where gas oil use is permitted by the
appliance manufacturer
• During the burner installation, check that the gas
oil and biofuel blends are in accordance with EOGB’s spec-
ications (please refer to the chapters “Technical Data” and
“Guidance for the use of biofuel blends up to 10%” within
the burner technical manual).
• If a bio blend is in use the installer must seek
information from the end user that their fuel supplier can
evidence that the blends of fuel conform to the relevant
standards.
• Check that the materials used in the construction
of the oil tank and ancillary equipment are suitable for
biofuels, If not these must be upgraded or replaced with
bio compatible parts. (Please contact EOGB for more info
on other biofuel compliant products)
• Particular attention should be given to the oil stor-
age tank and supply to the burner. It is recommended that
existing oil storage tanks are cleaned, inspected and any
traces of water are removed BEFORE biofuel is introduced
(contact the tank manufacturer or oil supplier for further
advice). If these recommendations are not respected this
will increase the risk of contamination and possible equip-
ment failure.
• In line oil lters should be replaced making sure
that they are bio compatible. It is recommended that a
good quality bio compatible oil lter at the tank and a
secondary 60 micron lter are used to protect the burner
pump and nozzle from contamination.
• The burner hydraulic components and exible oil
lines must be suitable for biofuel use (check with EOGB if
in doubt). EOGB have carefully chosen the specication
of the bio compatible components including the exible
oil lines to protect the pump, safety value and nozzle.
The EOGB warranty is dependent upon the use of EOGB
recommended components including the oil lines, being
used. The burner must be commissioned and combustion
parameters set to appliance manufacturer’s recommenda-
tions.
• Regularly check visually for any signs of oil leakage
from seals, gaskets and hoses.
• It is strongly recommended that with Biofuel use,
oil lters are inspected and replaced every 4 months. More
regularly where contamination is experienced.
• During extended periods of non operation and/or
where burners are using oil as a standby fuel, it is strongly
recommended that the burner is put into operation for
shorts periods at least every three months.
5.5 Working position
The burner is designed to operate only in the
positions 1, 2, 3and 4 (Fig. 5).
Installation 1, 2and 3is preferable, as it is the
only one that allows performing maintenance
operations as described in this manual.
Installation 4allows for working operations but
may incur maintenance issues as some adjusta-
ble settings may be obstructed
Any other position could compromise the correct op-
eration of the appliance. Installation 5is forbidden for
safety reasons, unless the burner has been supplied
to suit an upside down ring position or the burner has
been modied so the oil pump has been rotated 90
degrees to prevent the solenoid coil ring in a down-
wards orientation (please seek further assistance from
EOGB on this modication.)

6.1 Notes on safety for the electrical wiring
• The electrical wiring must be carried out with the electrical supply disconnected.
• Electrical wiring must be carried out by qualied 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 modications or connections dierent 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 ring failure.
• Check that the electrical supply of the burner corresponds to that shown on the identication 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 eciency.
Normally the boiler’s thermostat/pressure switch ensures the stopping of the burner. If this is not the case,
it is necessary to apply an in series timer switch, that turns o the burner at least once every
24 hours. Refer to the wiring diagrams.

7.1 Notes on safety for the rst start-up.
The rst start-up of the burner must be carried
out by qualied personnel, as indicated in this
manual and in compliance with the standards/
regulations and local authority legislation
Check the correct working of the adjustment,
command and safety devices.
WARNING
WARNING
In conformity with the application of the burner on the boiler,
adjustment and testing must be carried out observing the
instruction manual of the boiler, including verication of the
CO and CO2 concentration in the ue gases, their tempera-
tures and the average temperature of the water in the boiler.
7.3 Combustion adjustment
Combustion air is drawn in from outside, mean-
ing there may be notable changes in tempera-
ture, which can aect the percentage of CO2.
You are advised to adjust CO2 in accordance
with the graph featured.
Example: outside air temperature 10 °C, adjust
CO2 to 11.6% (± 0.2%).
A CO level should be kept to a minimum and
ideally less than 100ppm but if in doubt then
contact EOGB.
WARNING

Outside Air Temperature (°C) Fig. 10
7.4 Burner combustion adjustment
From a suitable test point on the boiler, or in the ue, a smoke
reading should be taken to ensure clean smoke-free com-
bustion.
With the aid of a ue gas analyser, and by making adjust-
ments to the air adjuster, the combustion can be set for max-
imum eciency (see Fig 10).
The air damper control rotates to adjust the amount of com-
bustible air (see Fig 11) and is locked in place by tightening
the air damper locking screw. (see “A” Fig 11 )
Air control
Clockwise = MORE air
Anti-Clockwise = LESS air Fig. 11
7.2 Preparations for Start up
Ensure that the correct size nozzle has been tted for the
application, The table below (see g 13) shows the deliv-
ery rates in kg/hr of light oil against nozzle size and pump
pressure (Normally 12 bar).
Ensure that the return oil line is not blocked or obstructed in
anyway, Failure to check will result in a pump sha seal
failure which will not be covered by warranty!
Close the main switch/thermostat to enable the burner to
start the pre-purge, Open Port “2” (see g 9) to allow air
to purge until oil is freely owing, then tighten Port “2”.
The solenoid coils will activate and release the fuel to the
nozzle for ignition aer the pre-purge. During this phase the
photocell will look for a light source given o by the ame.
If the ame has established then the burner will continue to
run, Failure of seeing this light signal will result in the control
box locking out.

Burner Operation and Commissioning
7.5 Pump pressure
The burner is tted with adjustable screw which regulates
the ame disk position, this adjustment allows for ne tuning
of the combustion by increasing or decreasing the air pas-
sage between the disk and head.
When operating with a reduced fuel delivery. This passage
must be proportionately opened ,turn Screw “10” (See Fig
12) in a anti clockwise direction to close.
When the burner is working with high fuel delivery, then
screw “10” (see g 12) would have to be turned in a
clockwise direction to open the head up.

Fig. 13
7.6 Nozzles installation
In order to guarantee that emissions do not vary, recom-
mended and/or alternative nozzles specied by the man-
ufacturers in the instruction and warning booklet should be
used. The information given in FIG 13 should only be used
as a guide where no information is provided by the boiler/
application manufacturer’s instructions/booklet.
It is advisable to replace nozzles every year during
regular maintenance operations.
The use of nozzles other than those specied by
the manufacturer may result in emissions that do
not conform to the values set by the regulations in
force, and in extremely serious cases, may cause
potential hazards to people and objects.
The manufacturing company shall not be liable for
any such damage arising from non-observance
of the requirements contained in this manual.
Nozzles recommended
• Delavan type A - W;
• Steinen type Q - S;
• Danfoss type H - S
Angle 60° & 80° are advisable
WARNING

8.1 Notes on safety for the maintenance
Periodic maintenance is essential for the good operation,
safety, yield and duration of the burner.
It allows you to reduce consumption and polluting emis-
sions and to keep the product in a reliable state over time.
Before carrying out any maintenance, cleaning or check-
ing operations:
The maintenance interventions and the calibra-
tion of the burner must only be carried out by
qualied, authorised personnel, in accordance
with the contents of this manual and in com-
pliance with the standards and regulations of
current laws.
Disconnect the electricity supply from the burn-
er by means of the main switch of the system;
Isolate the fuel supply.
DANGER
DANGER
DANGER
8.2 Maintenance programme
The combustion system should be checked ;
- at least once a year if Kerosene is being used by
a representative of the manufacturer or another
specialised technician.
- at least every 6 months if Gas Oil is being used
by a representative of the manufacturer or
another specialised technician.
Combustion head
Open the burner and make sure that all components of
the combustion head are in good condition, not deformed
by the high temperatures, free of impurities from the sur-
roundings and correctly positioned.
Clean the combustion head in the fuel exit area, on the
diuser disc.
Burner
Check for excess wear or loose screws and clean the out-
side of the burner.
Fan
Check to make sure that no dust has accumulated inside
the fan or on its blades, as this condition will cause a reduc-
tion in the air ow rate and provoke polluting combustion.
Photocell
Clean the photocell
Electrodes
Check the correct position of electrodes
Nozzles
It is advisable to replace nozzles every year or 6 months
depending on what fuel is being used. (see 9.2.1)
Do not attempt to clean the nozzle
Filters
Check the lter elements in-line and at the nozzle. Clean or
replace if necessary. If rust or other impurities are observed
inside the pump, use a separate pump to li any water and
other impurities that may have deposited on the bottom of
the tank.
Pump
Please check that the supply line and lters are clear. The
use of a pump vacuum gauge will assist in this. This meas-
ure permits the cause of the anomaly to be traced to either
the suction line or the pump.
If the problem lies in the suction line, check to make sure
that the lter is clean and that air is not entering the piping.
8.2.2 Checking & cleaning
Flexible Hoses
• Check the condition of the exible pipes
periodically. They have to be replaced at least
every 2 years.
• In case of use of gas oil and biofuel blends, it is
strongly recommended to inspect even more
frequently the hoses and replace them where
contamination has occurred.
• Check to make sure that the hoses are still in
good condition
The hose(s) supplied with this burner are suitable
for use with Kerosene, Gas oil and Biofuel blends of
FAME up to 100%
In case of use of a dierent Biofuel then please con-
tact EOGB for further information (a fuel specica-
tion may be requested)
Fuel tank
If water or contamination is present within the fuel tank, it
is essential that this is removed before the equipment is to
be used. This is extremely important when gas oil containing
Biodiesel is in use. If in doubt about how to achieve this then
please contact the fuel or oil tank supplier.
Boiler
Clean the boiler as indicated in the appliance accompany-
ing instructions in order to keep all the original combustion
characteristics intact, especially the ue gas temperature
and combustion chamber pressure.
Combustion
In case the combustion values found at the beginning of
the intervention do not respect the standards in force or in
any case, do not correspond to a proper combustion, con-
tact the Technical Assistant and allow them to carry out the
necessary adjustments.
Allow the burner to work for 10 minutes. and then check the
combustion readings with the parameters indicated within
the appliance instruction manual.
Then carry out a combustion check verifying:
• Flue gas temperature at the chimney;
• Content of CO2 (%);
• Content of CO (ppm);
• Smoke value according to opacity smokes index
according to Bacharach scale.
