2.6 Setting of ignition electrodes and brake

Measurements according to EN 15036-1:2006
Alt.1 The noise level of the burner can be reduced by equipping the burner with
silencer. Installation must be done so it does not prevent air supply to the
burner.
Alt.2 The burner’s noise level can be reduced by connecting the burner’s air
intake to the air duct that opens into an appropriate location. Installation
must be done so it does not prevent air supply to the burner.

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.
!Ændringer i strukturen af olien kan give anledning til
ændringer i viskositet, pumpbarhed og antændelse. Dette kan

3.1 Safety system
The safety system (safety switch for hatches, doors, water level, pressure,
temperature and other safety devices) must be installed in the safety circuit in
accordance with current regulations for the system.
The cables of the safety system must be separated so that the outgoing signal
is not placed in the same cable as the incoming signal.§

3.3 Function LMO14/24
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.

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 Delivery inspection
Make sure everything is delivered and the goods have not been damaged
during transit. If something is wrong with a delivery, report it to the supplier.
Transport damage must be reported to the shipping company.
4.5 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.

4.6 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 a minimal number of glands.
• The pipes are to be laid so that the oil supply hoses are not subjected
to tensile stresses or are excessively bent when the burner is swung
out or removed for service.
• The ½ ” oil lter should be installed so that the lter cartridge can
easily be replaced or cleaned. Self-cleaning lters are recommended
for oils of a higher viscosity or oils that contain signicant impurities.
• Oil-affected parts shall 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 shall
be located so that they do not bend or become subject to tensile load.
To the suction line on the pump (see paragraph 7.2 pos. 3) should the
supplied oil hose with 90° bend be connected.
• Bleed the oil system. The oil pump/oil preheater may be damaged
if run dry. The vacuum should not fall below 0 bar in the suction line
during start-up.
4.7 Electrical connection
Before work on the electrical connection, the current must be disconnected so
that the installation is isolated.
If the boiler has a 7-pole and a 4-pole Euro plug connector, they will usually
connect directly to the burner. Otherwise, use the supplied connectors. The
5-pole connector supplies the burner preheater with a separate 3-phase
supply. See connection under Electrical equipment.
1. Switch off the main switch.
2. Connect the Euro plugs, (see Electrical equipment).
3. Make sure the burner operations switch (S1) is off.
4. Turn on the main switch.

5. Mounting
1. Remove fan housing from  xing  ange.
2. Remove the brake plate from the oil line.
3. Install the selected nozzles, (see Technical data).
4. Install the brake plate on the oil line.
5. Remove the  ame tube from the  ange.
6. Install the  ange with gasket on the boiler.
7. Install  ame tube, be sure to install the drainage hole downwards
(not available on all  ame tubes) so that any oil spills can drain out.
8. Insulate between  ame tube and boiler door for reduced heat
radiation.
9. Install the fan housing on the  ange and lock with nuts.
10. Connect oil lines to the pump.
11. Connect the burner electrically.
5.1 Check oil line seals
When the burner has been installed and put into operation, the tightness
of the various coupling elements should be checked, in case of leakage -
retighten the coupling elements.
!Because the burner tube must be installed from the inside the
boiler, it must be possible to open the boiler or have a hinged
 ange that is designed so that it can be reconnected with the
burner tube installed.
