Acceptance inspection
Ensure that everything is delivered and that there is no transport damage.
If there is anything wrong with the delivery, please report it to the supplier.
Any transport damage should be reported to the forwarding company.
Preparations for installation
Ensure that the size and capacity range of the burner are suitable for the
boiler. Power data on the data plate refer to the minimum and maximum
power of the burner.
Distribution of oil
To ensure satisfactory operation it is essential that the oil distribution
system is correct. Observe the following:
- See Pump instructions for choice of tube diameter, tube length and
height difference.
- Fix the tubes so that the oil hoses are not subjected to tensile stress
or sharp bending when swinging out the burner or removing it for
service.
Electrical connections
The main power switch must be turned off before beginning the electrical
installation. If the boiler has a 7-pole contact device type Eurostecker it will
device. The operating thermostat and maximum thermostat, and also
are to be strapped.
If another electrical connection is used than the one recommended by
Bentone, there might be a risk of material damage or personal injury.
Choice of nozzle
See under Technical Data: Recommended nozzle and table of nozzles.
Setting of the shrouded disc and air fl ow
The burner is pre-set on delivery in relation to the nozzle provided. If the
size of the nozzle is changed the burner can be initially set according
to “Basic settings”. Note that it is only a question of a basic setting that
should be trimmed when the burner is started. This should include a

Suction plate
In the case of higher power, as well as with boilers featuring overpressure
in the combustion chamber, it is possible to achieve higher fan pressure
by altering the position of the suction plate, see illustration. The plate is
located beneath the outer half of the fan housing, see illustration, Clea-
ning the fan wheel.
Position 1 is normally used for nozzles up to 0.60 gph and position 4 for
larger nozzles. Position 2 and 3 are intermediate positions. Position 5
and higher does not give more pressure and they are not used.
Check that the plate is placed in the correct position. Otherwise the air-
cannot be adjusted to the correct value.
Cleaning the fan wheel
Unscrew the four fastening screws. Remove the half of the fan housing.
Check the position of the suction plate (position 1 up to and including
0.60 gph nozzle). Remove the suction plate. Inspect and clean the fan if
forward.

tings. For the individual boiler installation, adjustments can then always
be made to optimise economy, operational reliability and environmental
effects.
gas analysis and a soot meter.
The principle of the adjustment is:
- reduce the air, either with the air regulation or the nozzle assembly,
- increase the air to give a safety margin of 0,5-1% CO2before soot is
created. To throttle more with the shrouded disc (smaller reading on
better combustion, but if one goes too far there will be starting problems.
Throttling less with the shrouded disc gives a longer and more yellowish
The pressure in front of the shrouded disc can be utilised as an aid in
the adjusment. Recommended pressure, see under Basic settings. Re-

The automatic air damper is provided with a small spring at the right shaft
journal. Check that the air damper moves easily.

BFP 41L3 operating principle
When the pump is started, oil is drawn from the suction port (S) th-
The oil then moves to the pressure side of the gearwheel and is thus
pressurised. The pressure is controlled and maintained at a constant
pre-set level by diaphragm (D) of the control valve (P1)
The control valve (P1) distributes the oil supplied by gear-set (C) bet-
ween the nozzle connection (E) and the return port of the pump (R).
The amount of oil consumed is determined by the pressure set on the
control valve (P1) and by the size of the oil nozzle in the nozzle line.
The control valve (P1) operates as follows:
- When the oil attains opening pressure, the port to the return side opens.
- The diaphragm and the spring keep a constant pump pressure at the
set value.
- If the pump becomes overloaded, i.e. if an attempt is made to take out
more oil than the gear-set can deliver in the prevailing circumstances,
the oil pressure will fall below the set value causing the valve to close,
by diaphragm (D), to the return port (R) and return to the starting posi-
tion.
This can be remedied by:
- Lowering the pump pressure.
- Reducing the amount of oil delivered, i.e. changing to a smaller nozzle.
- Changing to a pump with higher capacity.

The suction line tables consist of theoretically calculated values where
the pipe dimensions and oil velocity have been matched so that turbulent
pressure losses and noise in the piping. A piping system consists normally
of drawn copper pipes and four bends, a non-return valve, a shut-off valve
The sum of these individual resistances is negligible. The tables do not
include any lengths exceeding 100 m because experience shows that
longer lengths are not needed.
The tables apply to standard fuel oil of normal commercial quality ac-
cording to current standards. On commissioning with an empty tube
system the oil pump should not be run without oil for more than 5 mi-
nutes. The tables state the total length in metres of the suction line at a
nozzle capacity of 2.5 kg/h. Maximum allowed pressure at the suction
and return port is 2.0 bar.

OIL BURNERS MAINTENANCE
INSTRUCTIONS
General information
Keep the boiler room clean. Ensure that the boiler
room has permanent fresh air intake. Switch off before
dismantling the oil burner.
At hinged mounting, make sure that an automatic safety
switch is fitted, so that the burner cannot start when
theswing door is open.
Don´t use the oil fired boiler to burn paper or
rubbish,unless the boiler is especially fitted with a hinged
door tomake this possible.
Don´t fill tank while burner is working.
Starting precautions
Make sure that the oil tank is not empty
Make sure that the valves on oil and water supply pipes
areopen.
Make sure that the boiler flue damper is open.
Make sure that the boiler thermostat is set at the correct
temperature.
Switch on the current. Most relay systems have a
delayed action so that the burner will not start for
perhaps 20 seconds.
With heavy oil the delay will be longer as the burner
will notstart until the oil in the preheater reaches the
requiredtemperature.
If the burner will not start
Press the reset button on the relay. Check that the
thermostats are correctly adjusted.
Don´t forget the room thermostat, check that any
fusesare intact and main switch is on.
If the burner starts but does not ignite
Make an attempt to start the burner.
Never make close repeated start attempts.
Don´t restart the burner until the boiler is free from oil
gases.
If the burner still does not ignite send for the service
engineer.
When switching off during summer
Always use the main switch to cut out the burner even
when adjusting the burner or cutting off the heating for
ashort time. For longer periods of shut down, close all
valves and the oil supply stop-cock.
Clean the filter and nozzle by washing in petrol or
paraffin.
Make sure the filter medium is not damaged or defective.
Protect electrical gear from damp.
Warning
Never stand too near or put your face to the inspection
or fire door, when the burner is about to start.
Never use a naked flame to ignite oil if the electrical
ignition fails.
Always wait for about 10 minutes for the unburnt gases
to disperse before restarting the oil burner if it has failed
to ignite previously.
