those burner components most likely to be subject to
wear and tear;
• the use of non-original components, including spare
parts kits, accessories and optional;
• force majeure.
The manufacturer furthermore declines any and every responsibil-
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 identied as bio compatible.
No warranty is given in relation to the use of components which
are not so identied 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 aected 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 specication 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 dierently 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 specication
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 specication 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 verication 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
eectively 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 oen 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.
• Modication 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 specic 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 inammable
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 inammable 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 specic 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 qualied 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 modica-
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.
