General requirements RME
This is a burner designed for FAME, B-100 (RME) fuel. 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 cause oxidation damage to components in the oil
system. The fuel should be stored in a cool area to minimise these problems.
The RME cistern must be made of metal or dark coloured plastics approved
for the fuel.
The design of the equipment on the burner permits the use of EO1 type
oil without modification, although with appropriate adjustments to the
combustion after changing the fuel type.
Oil burners must be installed in accordance with local regulations. The
installer must therefore be knowledgeable of the regulations pertaining to oil
and combustion.
Installation should be carried out as a one-pipe system and used together
with the bleeder to vent the system, and an appropriate filter must also be
in place. Copper should be avoided in RME fuel systems since the fuel and
copper have an oxidising effect on each other.
Only oil suitable for the burner must be used and then in combination with
a suitable oil filter designed for FAME, B-100 (RME) and installed before the
burner’s oil pump.
The tank should be cleaned and the water should be checked regularly to
prevent problems related to corrosion and microorganisms. This should be
done once a year.
If the burner is replacing an existing burner, ensure that the oil filter is
changed to a filter designed for FAME, B-100 (RME). Installation may only be
performed by qualified personnel.
Care should be taken by the installer to ensure that no electrical cables or oil/
gas pipelines are crushed or damaged during installation or service.
Burners that run on FAME, B-100 (RME) fuel are and must be equipped with
parts designed for this fuel. This applies in particular to oil-related parts such
as the pump, solenoid valve, oil filter and hoses with fire-retardant sleeves. It
is very important when carrying out a service to replace old parts with new
parts of the same quality.
Maintenance
The boiler/burner must be checked regularly for faults or leakage. Any boiler/
burner that uses FAME (RME) fuel must be serviced at least twice a year. It is
very important that worn parts are replaced at the time of servicing with new
parts of the same quality.
Oil hoses must be of high-quality fluoride rubber or PTFE intended for FAME,
B-100 (RME).
The hoses must be fitted with fire-retardant sleeves in order to satisfy
requirements according to EN-ISO 6806.

Make sure the hole pattern on the boiler is designed for burner flange.
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
specific distribution pattern.
It should be noted that the scattering angle and distribution pattern changes
with pump pressure.

!Altered structure of the oil can give rise to altered viscosity, pumpabilty and
ignitability. This can cause the pump, valves and nozzles to get blocked.
2.7 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 defining 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 significantly 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 flow.
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 filters, transport oil pump, preheater and reduction valve to provide
trouble -free operation. Max filter size is 120 µm and the oil may need to be
filtered 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 flushed with fuel oil after the standstill. This
procedure ensures a good start after standstill.

3. Installation
3.1 Acceptance inspection
Make sure everything is delivered and the goods have not been damaged
during transit. If something is wrong with the delivery, report it to the supplier.
Transport damage must be reported to the shipping company.
3.2 Preparations for installation
Check that the burner's dimensions and capacity range are suitable for the
boiler in question. The power data on the type sign refers to the burner's
min. and max. power.
3.3 Distribution of oil
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 filter should be installed so that the filter cartridge can easily
be replaced or cleaned. Self-cleaning filters are recommended for oils
of a higher viscosity or oils that contain significant 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
fitted 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.
3.3.1 Proposed pipe routing for oil distribution
systems without transport pump
This type of connection should be used only when the oil has a viscosity less
than 30 mm²/s

3.4 Electrical connection
Before electrical installation begins, the main power switch must be turned off.
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.

3.5 Nozzle selection
See under Technical data: Recommended nozzle and Nozzle table.
If, after selecting the nozzle, burner type B45-2 MF has difficulty starting, this
may in some cases be due to the selection of nozzle made for the first stage.
Selecting a nozzle with a smaller effect in the first stage may solve the
problem.
3.6 Setting of brake plate and air flow
Prior to commissioning, the basic settings of the burner can be set in
accordance with the diagram. See under Basic settings. Note that it is simply
a matter of a basic setting that should be adjusted retrospectively once the
burner has started. You should then conduct a flue gas analysis and soot
quantity measurement.

3.7 Burner installation
1. Separate the burner body and the flange.
2. Remove the brake plate from the oil pipe.
3. Install the selected nozzle. (See Technical data)
4. Install the brake plate on the oil pipe
5. Remove the burner tube from the flange.
6. Install the flange with gasket on the boiler.
7. Install the burner tube on the flange. Make sure that the hole in the
front of the burner tube pipe is pointing down. This allows any drops of
oil to flow out.
8. Insulate between the burner and boiler door to reduce radiated heat.
9. Slide the burner body on the guides.
10. Lock the burner body using with the nut/nuts.
11. Connect the oil hoses to the pump, see paragraph 2.3.
12. Connect burner electrically, see paragraph 2.4.
3.8 Check oil line seals
Once the burner has been installed and commissioned, the seals of the
various coupling elements should be checked (A). These may, due to
temperature fluctuations or transportation, start to leak.
Temperature fluctuations arise from the process of heating oil used in these
burners.
When a leak is detected, it is usually sufficient to tighten the coupling
element that is leaking.
!Because the burner tube must be installed from the inside the
boiler, it must be possible to open the boiler or have a hinged
flange that is designed so that it can be reconnected with the
burner tube installed.

4.1 B45-2 MF 2-stage burner
When the installation calls for heat, the burner's preheater starts to heat the
oil. Once the oil reaches the set temperature, the burner receives the signal
to start. Hot oil is flushed throughout the burner's oil system.
After the end of the blow period, the min. load solenoid valve (Y1) receives
voltage and closes. The oil pressure builds up in the nozzle holder and the
cut valve (V1) for min. load opens. The oil is atomised in the nozzle (N1) and
ignited. A small amount of oil and the nozzle assembly compressed air flow
is channelled back to the return side of the pump through the leak oil line (L).
Solenoid valve (Y2) for maximum load opens when the installation calls for
maximum load. The pressure difference created over the cut valve (V2) for
maximum load makes this valve open. The oil is atomised in the nozzle and
ignited.
When the heat in the installation reaches break temperature, solenoid valve
(Y2) for maximum load closes to reduce to minimum load. The pressure
equalisation which then takes place over the max. load cut valve (V2) gets
this to close and the flame is reduced to min. load.
Once the installation has reached the desired temperature, a solenoid valve
(Y1) is rendered without power and then opened; cut valve (V1) is then
subsequently closed. This process extinguishes the burner flame. In the
same process, oil heating is also interrupted.
