2.5 Setting of brake disc and air flow
Once the different output modes have been selected prior to commissioning,
basic settings for the burner can be made as shown in the air damper and
brake disc diagrams. See under Default settings. Note that it is simply a
matter of a default setting that should be adjusted retrospectively once the
burner has started. You should then conduct a flue gas analysis and soot
quantity measurement.
2.6 Burner installation
2.6.1 Hole pattern
Make sure the hole pattern on the boiler is designed for burner flange.
Combustion device d1d2d3
B 70-3 (205) 225 M14 (310) 324-390
d1* If the burner tube is installed from inside the boiler.
d3* The hole pattern can be moved down if the burner tube is installed from
the front and the tabs in the flange are removed.
2.7 Recommended nozzle and
pressure
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.
Nozzle: 45° Solid/semisolid
60° Solid/semisolid
80° Solid/semisolid
Pump pressure: 14 bar (12-16 bar) depending on pump model

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
Refer to servicing schedule
3.1.4 Before commissioning
The 3-stage thermostat must be installed before operation. Contact Bentone
for more information about the appropriate product.
3.1.5 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
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.
• 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.
4.4.1 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
6 mm²/s.
1. Oil filter
!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.

4.6 Mount the burner on the boiler
1. Separate the burner body and the flange.
2. Pull out the burner on the guides.
3. Remove the brake disc from the oil pipe.
4. Install the selected nozzle, (see Technical data).
5. Install the brake disc on the oil pipe.
6. Remove the burner pipe from the flange.
7. Install the flange with gasket on the boiler.
8. 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.
9. Insulate between the burner and boiler door to reduce radiated heat.
10. Install the burner body on the flange.
11. Lock the burner body using with the nut/nuts.
12. Connect the oil pipes to the pump, refer to the chapter - servicing of
burners.
13. 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.
!If the burner tube must be installed from the inside
of the boiler, this means that the boiler must be
opened or have a spectacle flange that is desig-
ned so that it can be reconnected with the burner
tube mounted.

Effects and nozzle selection from the example above. The values are
available in the tables for setting values of inserts or air dampers.
Insert Step 1/2 = 17
Step 3 = 37
Low load air damper =22°
MV2 open =35°
Air damper step 2 =52°
MV3 open =60°
Air damper step 3 =75°
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.

4.11 Insert control movable brake disc
Insert control is used to achieve a pressure drop over the brake disc as
favourable as possible in the various power stages.
3- nozzles
The insert control sets the brake disc mode between Step 2 and Step 3
using a hydraulic piston. There are two adjustments to be made on the insert
a low load adjustment and a high load adjustment.
Low load
The low load adjustment takes place by changing the guide
rail’s mounting to the hydraulic piston. This takes place using
a locking screw located through an oval hole. In the default
setting, the value that is read in the table, is used for the setting
values for the chosen power for step 2. During operation, the
insert is adjusted in order to achieve the best function.
Undo the locking screw (C).
Set the desired position on the scale (A) by pushing the disc in
the desired position.
Tighten the screw (C).
High load
The high load setting takes place by adjusting the hydraulic
piston’s length of stroke using set screw (D). Loosening the set
screw increases the length of stroke while tightening it reduces
the length of stroke
Set the desired position on the scale (A) using the set screw (D)
(left turn reduces pressure loss, the brake disc is moved outward).
If pulsation occurs, the changed pressure drop over the brake disc may
result in the pulsation stopping
4.12 Air setting
When the burner’s power stage has been selected, check the setting values
for air dampers in table. Read the damper angle for each of the power
stages. This must then be used when the settings are made in the burner’s
control system.
Check the air settings by conducting a flue gas analysis.
