2.5.1 Hole patten
Make sure the hole pattern on the boiler is designed for burner ange.
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
specic 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
2.6 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 dening 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 signicantly 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.
