• is to be regarded as part of the burner and must always be kept near
the installation site.
• must be read prior to installation.
• is intended for use by authorised personnel.
1.1 Delivery inspection
• Make sure everything is delivered and the goods have not been
damaged during transit.
Transport damage must be reported to the shipping company.
• If something is wrong with a delivery, report it to the supplier.
1.2 Safety
- before installation:
• Installation and work on the burner and associated system
components may only be carried out by persons who have undergone
relevant training.
• The product is packaged to prevent damage from occurring when
handled – Handle the product with care! Lifting equipment must be

accordance with current mains electricity regulations and in a
professional manner.
• Make sure that the burner is suitable for the application (see Technical
Data).
• All components must be installed without being bent, twisted or
subjected to mechanical or thermal forces that affect components.

5Bentone
• Care must be taken by the installer to ensure that no electrical cables
or fuel lines are pinched or otherwise damaged during installation or
service.
• Flame tubes, fan wheels and air dampers, for example, may contain
sharp edges.
- before  rst start:
• The burner must not be put into operation without proper safety and
protection devices.
• Permitted ambient temperature during operation -10 to +60 °C. Max.
80% relative humidity, no condensation.

1.3 General requirements FAME/RME
• The fuel must meet the requirements of standard EN 14214 for FAME.
• The fuel must be stored and used according to the manufacturer’s
instructions. It should typically be used within 6 months of
manufacture. Fuel that is allowed to age loses its oxidation stability
and produces aggressive constituents. These may cause oxidation
damage to components in the oil system. The fuel should be stored in
a cool and dark area.
• The RME tank must be made of metal or dark coloured plastics
approved for the fuel.
• Burners fuelled by FAME (RME) are – and must be – equipped with
parts designed for this fuel. This applies to oil-related parts such as
the pump, solenoid valve, oil lter and hoses.
• Oil hoses must be of high-quality uoride rubber or PTFE intended for
FAME/RME, and the hoses must be tted with re-retardant sleeves in
order to satisfy requirements according to EN-ISO 6806.
• The installation should be performed as a single-pipe system. Copper
should be avoided the fuel system since the fuel and copper have an
oxidising effect on each other.
• Annual cleaning and checking for the presence of water in the tank
should be done to avoid corrosion and microorganisms.

2.7 Recommended nozzle and pressure
Because of the various boiler types with varying furnace geometries and
furnace loads, it is impossible to commit to a certain scattering angle or a
specic distribution pattern.
It should be noted that the scattering angle and distribution pattern changes
with pump pressure.

2.8 Oil grades
The burner is tested and approved for pure rapeseed oil that complies with
standard DIN 51605:2010-10.
The burner is designed to be able to burn oils with a higher viscosity, both
of biological and fossil origin. The maximum viscosity with which the burner
is tested is 75 mm²/s, 0–130°c. Another way of dening which kind of oil
the burner can handle is that the oil must be of such a nature that it can be
pumped by the burner pump at the temperature the oil has at the point of
access to the pump.
The burner, without the pump, is designed to withstand the more corrosive
environment often created by oils of biological origin.
The Suntec E1069 pump is NOT designed for aggressive oils.
The burner pump has a service life of approx. 3–5 years if the oil is of a grade
that complies with standard DIN 51605:2010-10. If oil of a different grade
is used, especially if the oil contains contaminants such as particles, press
residue, metal swarf etc., or has chemical aggression, the pump may be
expected to have a signicantly shorter service life.
The pump is considered to be a wearing part and is not covered by the
warranty.
Pressure at the pump inlet must be -0.30 to max 2.0 bar. If there is a noise
from the pump, the oil is not pumpable at the current temperature or ow.
A transport oil pump combined with preheater is then needed to supply the
burner’s pump with oil for trouble-free operation.
The oil distribution system must be designed with the required equipment
such as lters, transport oil pump, preheater and reduction valve to provide
trouble -free operation. Max lter size is 120 µm and the oil may need to be
ltered in several steps.
In the case of a standstill in which the oil can be expected to change structure,
for example aging or phase transitions due to temperature and storage, the
burner must be ushed with fuel oil after the standstill. This procedure ensures
a good start after standstill.

3.3 Function
1 Switch on operating switch and twin thermostat
A spark is formed. The air damper motor opens the damper to low load
position. The burner motor starts, the prepurge goes on till the prepurge
period expires and the solenoid valve 1 opens (2).
2. Solenoid valve 1 opens
Oil mist is formed and ignited. The photocell indicates a ame. The ignition
spark goes out after ame indication (see Technical data oil burner control).
3.

b
The safety time expires
If no ame is established before this time limit the control cuts out.
If for some reasons the ame disappears after this time limit, the burner will
make an attempt to re-start.
4 High/Low thermostat ON
The burner is in operating position and can now change between full load
and low load.
4-5 Operating position
If the burner operation is interrupted by means of the main switch or the
thermostat, a new start takes place when the conditions in accordance with
point 1 are fullled.
The oil burner control cuts out
A red lamp in the control is lit. Press the reset button and the burner re-
starts.

3.4 Colour codes
When the burner starts, three signal lights in the reset switch indicate the
normal sequence, as well as provide indication if something abnormal is
happening in accordance with the following table:
Preheater in operation Solid yellow
Ignition switched on Flashing yellow
Normal operation Solid green
Operation, poor ame signal Flashing green
Undervoltage Flashing yellow-red

False light Flashing red-green
Communication mode Fluttering red
3.5 Fault codes
When the red light for a blocked relay box comes on, you can get information
about what has caused the problem by pressing and holding the reset button
for 3 seconds.
The number of ashes below is repeated with a pause in between.
2 ashes No ame signal when safety time expires
4 ashes False light during start
7 ashes 3 x Losses of ame during operation
8 ashes Time-out for preheater *
10 ashes Incorrect wiring, internal fault or simultaneous occurrence of
two faults
* In order for this fault code to occur, the preheater shall not reach its
cut-off temperature within 10 mins. from switch on.
To return to normal operation: Press the reset button for 1 second.
If the reset button is instead kept pressed a second time for at least 3 seconds,
you can, via an interface, obtain the corresponding information on a computer
or ue gas analyser.
To return to normal operation: Press the reset button for 1 second.

4. Installation
4.1 General instructions
Oil burners must be installed in accordance with local regulations. The installer
must therefore be knowledgeable of the regulations pertaining to oil and
combustion.
Only oil suitable for the burner must be used and then in combination with a
suitable oil lter installed before the burner’s oil pump.
If the burner is replacing an existing burner, ensure that the oil lter is
replaced or cleaned. Installation may only be performed by qualied
personnel.
Care should be taken by the installer to ensure that electrical cables and oil
lines are not pinched or otherwise damaged during installation or servicing.
4.2 Inspection and maintenance
The system must be maintained at the interval specied in the service
schedule. If the burner is in a dirty environment, service should be done at
more frequent intervals.
4.3 Start-up
In order to obtain the correct setting, a ue gas analysis and temperature
measurement must be carried out. Otherwise, there is a risk of soot build up,
poor eciency or condensation in the chimney. The system must be ne-tuned
at start-up. The temperature in the chimney at a depth of 0.5 m must be at
least 60 °C to prevent condensation.
4.4 Preparing for installation
Check that the burner’s dimensions and capacity range are suitable for the
relevant boiler. The power data on the rating plate refers to the burner’s
minimum and maximum power.
4.5 Oil distribution
In order to achieve good reliability, it is important that the oil distribution
system is designed correctly.
Take the following into account:
• Selection of pipe diameter, pipe length and height difference; see
Pump instruction.
• Pipelines are to be laid with the fewest possible number of glands.
• The pipes are to be laid so that the oil supply hoses are not subjected
to tensile stresses or become excessively bent when the burner is
swung out or removed for servicing.
• The oil lter should be installed so that the lter cartridge can easily
be replaced or cleaned.
• Parts in contact with oil must be selected in materials that are capable
of withstanding the medium’s physical properties.
• When installing oil hoses, check that the inlet and return hoses are
tted to the appropriate connection on the oil pump. The hoses must
be located so that they do not bend or become subject to tensile load.
• Bleed the oil system. The oil pump/oil preheater may be damaged if
run dry. The vacuum in the suction line should not fall below 0.3 bar
during start-up.

4.6 Electrical connection
• Before work on the electrical connection, the current must be
disconnected so that the installation is isolated.
• Electrical connection must be done in accordance with the applicable
regulations.
• Burners must be connected to an all-pole switch.
• Connection must conform to the wiring diagram.
• Use appropriately sized fuses.
