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.

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 Pressure switch for min. oil
pressure
The burner control unit has a connection for a pressure switch for min. oil
pressure. If the facility regulations do not require this switch, a jumper should
be fitted between terminals 12 and 13 of the terminal block to close the
circuit and enable the burner to be started.
4.5 Pressure switch for max. oil
pressure
The burner control unit has a connection for a pressure switch for max. oil
pressure. If the facility regulations do not require this switch, a jumper should
be fitted between terminals 2 and 3 of terminal block X5-02 in the automatic
control unit to close the circuit and enable the burner to be started.

!Be sure to fill the
burner oil system
before starting it for
the first time.
!The oil filter must
be installed befo-
re the burner’s oil
pump.
4.7 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
!If any electrical connection is used other than that recommended by Bentone, there may be a danger of
damage to property and personal injury.
4.6 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.

!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 designed so that it can be reconnected with the
burner tube mounted.
4.8 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
4.9 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.

4.10 Adjusting the air setting
Operate the burner as described in the “Manual output” chapter of the LMV
section
Step 1:
1. Set the output to low load.
2. Remove the guard (D) from the hydraulic adjuster.
3. Loosen the screw (A), turn the damper to the desired position, and
retighten the screw (A).
Step 2:
4. Set the output to high load.
5. Use a hex key to screw the socket (B) in to decrease or out to increase
6. The damper position can be read on the damper scale (C).
7. Check/adjust combustion.*
8. Reset the burner to automatic operation.

5. Setting the burner
5.1 Setting the combustion assembly
It may sometimes be necessary to adjust the combustion
assembly, i.e. the position of the brake plate in the burner tube.
5.1.1 Setting the combustion assembly
The burner is equipped with a lever that changes the position
of the brake plate in the combustion head. This is used to set
the correct pressure drop across the combustion assembly
and thereby obtain good combustion without ripples. Make the
adjustment by turning screw X
The best position is, among other things, dependent on the input
power and overpressure in the boiler
A general rule of thumb is that the smaller the capacity, the smaller the gap
should be between the brake plate and the combustion assembly.
The position of the brake plate also has an impact on the quantity of air
supplied for combustion.
This means that once the brake plate has been adjusted, the combustion
should be checked and, if necessary, the setting of the air damper adjusted
to obtain good combustion.
A left turn opens the brake plate, providing a lower pressure drop and more
air to the combustion process.
A right turn closes the brake plate, providing a higher pressure drop and less
air to the combustion process.

5.2 Pressure switch for min. oil
pressure
The burner control unit has a connection for a pressure switch for min. oil
pressure. If the facility regulations do not require this switch, a jumper should
be fitted between terminals 12 and 13 of the terminal block to close the
circuit and enable the burner to be started.
5.3 Pressure switch for max. oil
pressure
The burner control unit has a connection for a pressure switch for max. oil
pressure. If the facility regulations do not require this switch, a jumper should
be fitted between terminals 2 and 3 of terminal block X5-02 in the automatic
control unit to close the circuit and enable the burner to be started.

5.4 Setting the air pressure switch
The air pressure switch should block the burner if the air quantity supplied
for combustion is insufficient. The air pressure switch must be set so that,
if there is a defective air supply at the burner’s max. or min. capacity, it
reacts before the monitored pressure falls so much that it results in poor
combustion.
Setting for air pressure switch
1. Remove the protective cover, screw (Y).
2. Start the burner.
3. Carefully turn the scale on the air pressure switch clockwise until the air
pressure switch stops the burner. Is the tolerance on the scale for
the min. air pressure switch approx. ±15%?
4. Try to find the pressure at which the burner stops for both the
minimum and maximum input power by turning the scale. Make a note
of the values and then set the air pressure switch on the basis of the
highest pressure noted at which the burner stopped.
5. The air pressure switch should be set to a pressure approx. 10–15%
lower than the highest noted pressure at which the burner stopped.
6. After setting the air pressure switch, perform repeated starts and run
through the burner’s set output range several times. This is to ensure
the reliable function of the burner. If breakdowns or interruptions occur,
the air pressure switch is probably set to a too narrow position.
7. Fit the protective cover, screw (Y).
!Be careful when adjusting the air pressure switch;
it contains a live component.
