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.

3. General instructions
3.1 General rules
The installation of an oil burner should be carried out in accordance with
local regulations. The installer of the burner must therefore be aware of all
regulations relating to oil and combustion.
Only oil suitable for the burner should be used and then in combination with
a suitable oil filter before the oil pump of the burner.
If the burner is replacing an existing burner make sure that the oil filter
is replaced or cleaned. The installation must only be undertaken by
experienced personnel. Care should be taken by the installer to ensure
that no electrical cables or fuel/gas pipes are trapped or damaged during
installation or service/maintenance.
3.1.1 Installation and maintenance instructions
The maintenance instructions supplied with the burner must be kept at an
easily accessible location in the boiler room.
3.1.2 Instructions
The user must be receive detailed instructions concerning the functionality
of the oil burner and entire system. It is the responsibility of the supplier to
provide the user with instructions.
3.1.3 Inspection and maintenance
The boiler/burner should be examined regularly for any signs of malfunction
or oil leakage. (See service schedule)
3.1.4 Start up
In order to obtain the correct setting, a flue gas analysis and temperature
measurement must be carried out. Otherwise, there is a risk of soot build
up, poor efficiency or condensation precipitation in the chimney. The system
must be fine-tuned at start-up. The temperature in the chimney must be at
least 60 °C at 0.5 m down in the chimney to prevent condensation.

4.2 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.
4.3 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.
4.4 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 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 fit-
ted 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.
-Bleed the oil system. The oil pump/oil preheater may be damaged if
run dry. The vacuum should not fall below 0.3 bar in the suction line
during start-up.
!Be sure to fill the
burner oil system
before starting it for
the first time.
!If any electrical connection is used other than that recommended by Bentone, there may be a danger of
damage to property and personal injury.
4.5 Electrical connection
• Before work on the electrical connection, the current should be disconnected so that the installation
is isolated.
• Electrical connection must be done in accordance with the applicable regulations.
• Burners should be connected to an isolator switch.
• The connection should be made in accordance with the wiring diagram.
• Fuse rating is as required
!The oil filter must
be installed befo-
re the burner’s oil
pump.

4.6 Mount the burner on the boiler
1. Separate the burner body and the flange.
2. Remove the brake disc from the oil pipe.
3. Install the selected nozzle. (See Technical data)
4. Install the brake disc on the oil pipe
5. Remove the burner pipe from the flange.
6. Install the flange with gasket on the boiler.
7. Install the burner pipe on the flange. Make sure that the holes in the
front edge of the burner pipe are pointing down (not on all burner
pipes). This allows any drops of oil to run out.
8. Insulate between the burner and boiler door to reduce radiated
heat.
9. Install the burner body on the flange.
10. Lock the burner body using with the nut/nuts.
11. Connect the oil pipes to the pump, refer to the chapter - servicing
of burners
12. Connect the burner electrically, refer to the chapter - servicing of
burners
4.7 Check oil line seals
Once the burner has been installed and commissioned, the seals of the
various coupling elements should be checked (A).
When a leak is detected, it is usually sufficient to tighten the coupling
element that is leaking.

4.8 Air adjustment with damper motor
4.8.1 Air setting
The damper motor turns the damper between 3 preset positions: fully
closed, low capacity and high capa-city. These positions are controlled in
the motor by cams which are set by means of the coloured disks. In addition
there is a black disk controlling the connection of solenoid valve 2.
If the air volume needs changing: Remove the cover from the damper motor
and change the position of the cams by turning them by hand. See fig
Low capacity:
Adjust the operating switch to high capacity (II).
-Reduce the air volume:
Turn orange cam towards 0°.
-Increase the air volume:
Turn orange cam towards 90°.
Adjust the operating switch back to low capacity and check.
Full capacity:
Adjust the operating switch to low capacity (I).
-Reduce the air volume:
Turn red cam towards 0°.
-Increase the air volume:
Turn red cam towards 90°
If the red cam is moved, the black one must also be moved.
Reset the control switch to High Load and make sure the correct air quantity
is reached.
Releasing button:
By pressing the button and
snapping it down, the motor will be
released and the damper can easily
be turned. This function facilitates an
exchange of damper motor.
!The blue cam is

5. Burner installation
Burner output 150 kW
Estimated nozzle output 150 kW/11,86 kWh/kg*= 12,6 kg/h
Nozzle selection in accordance with the table. (See technical data) Nozzle
selection is based on the selected pump pressure and the desired effect.
According to the nozzle table, this provides the following nozzle.
Selected pump
pressure
9,0 bar
Nozzle 3,50 gph 3.50 gph distributed to two nozzles,
e.g. 2.0 gph at stage-1 and 1.5 gph at
stage-2
Basic settings should only be seen as setting values to get burner to start
and establish a flame. Once the burner has started and established a flame,
it will be necessary to adjust the settings so that they are adapted to the
installation in question and the fuel used at the time.
Basic settings
The setting value for 150 kW according to default settings tables. Refer to
6.2 for the correct settings procedure. Nozzle assembly adjustment, brake
plate B30. Air setting 6.3.
5.1 Examples of basic setting B 30
Nozzle B30-2
Burner output 150 kW
150 / 11,86 = 12,6 kg/h
According to the nozzle table, this provides the following nozzle.
Step 1 2,00 Gph = 79kW
Step 2 1,50 Gph = 63kW
Basic setting B30-2
The values are available in the tables for setting values of inserts or air
dampers.
Insert 150kW = 2
Low load air damper, orange =40°
MV2 Open, black =50°
Air damper step 2, red =80°
These are the default settings and controlling the combustion will take place
during operation.
Selection of power and connection between the different power stages must
be selected and adjusted so that the system achieves good functionality

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. A flue gas analysis and
soot quantity measurement must be carried out when fine-tuning the burner.
