!The burner pump is factory set at 24 bar and

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.

at the temperatur
point.
!Altered structure of the oil can give rise to altered viscosity, pumpabilty and ignita-
bility. This can cause the pump, valves and nozzles to get blocked
1.7 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.

2. INSTALLATION
2.1 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.
2.2 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.
2.3 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.
2.3.1 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

!Be sure to fill the burner
oil system before starting
it for the first time.

2.3.2 Proposed pipe routing for oil distribution systems with transport
pump, basket filter and seal filter
2.4 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.

2.5 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.
2.6 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.
2.7 Burner installation
2.7.1 Hole pattern
Make sure the hole pattern on the boiler is designed for burner flange.
