Because of different boiler types existing on the market,
with varying combustion chamber designs, it is not

3. GENERAL
INSTRUCTIONS
General rules
This is a burner designed for FAME (RME) fuel. The fuel must meet the
requirements of standard EN 14214 for FAME. The equipment on the burner
is, however, of such a quality that it is possible to use EO1 type oil without
modification, although with appropriate adjustments to the combustion
values after each change of fuel type.
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 must be used and then in combination with a
suitable oil filter designed for FAME (RME) and installed before the burner’s
oil pump.
If the burner is replacing an existing burner, ensure that the oil filter is
changed to a filter designed for FAME (RME). Installation may only be
performed by qualified 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.
Burners which are fuelled by FAME (RME) are and must be equipped with
parts designed for this fuel. This applies in particular to oil-related parts such
as the pump, solenoid valve, oil filter and hoses. It is very important when
carrying out a service to replace old parts with new parts of the same quality.
Installation instructions
General installation instructions accompany the burner and should be left in
a prominent place adjacent to the burner.
Adjustment of burner
The burner is from the factory preset to an average value that must then be
adjusted to the boiler in question.
All burner adjustments must be made in accordance with boiler
manufacturers instructions.These must include the checking of flue gas
temperatures, average water temperature and CO2 or O2 concentration.
To adjust the combustion device, start by increasing the air volume and the
nozzle assembly somewhat. When the burner starts it is burning with excess
air and smoke number 0. Reduce the nozzle assembly adjustment until soot
occurs, and then increase the adjustment to make the soot disappear again.
Then the volume of air is reduced until soot occurs and increased again to
reach a combustion free of soot.
By this procedure an optimum adjustment is obtained. If larger nozzles are
used the preadjustment of both the air volume and the nozzle assembly
must be increased.

8
Bentone B30A RME, B40A RME
A whistling sound may be heard which can be eliminated or reduced as
follows: Increase the nozzle assembly adjustment somewhat. The CO2-
content will then be reduced and the air volume has then consequently to be
reduced.
Condensation in chimney
A modern burner works with less excess air and often also with smaller
nozzles than older models. This increases the efficiency but also the risk of
condensation in the chimney. The risk increases if the area of the chimney
flue is too large. The temperature of the flue gases should exceed 60°C
measured 0,5 metres from the chimney top.
• Measures to raise the temperature:
• Insulate the chimney in cold attics
• Install a tube in the chimney
• Install a draught regulator (dilutes the flue gases during operation and
dries them up during standstill)
• Increase the oil quantity
• Raise the flue gas temperature by removing turbulators, if any, in the
boiler.
Pump adjustment
See separate description.
Maintenance
The boiler/burner should be examined regularly for any signs of malfunction
or oil leakage. Any boiler/burner that uses FAME (RME) as fuel must be
serviced at least twice a year.
Oil supply
The oil line should be dimensioned in accordance with the pump
manufacturer´s instruction. A filter designed for FAME (RME) that prevents
any particles in the oil from reaching the burner is mounted in the burner’s
suction pipe. If the installation consists of several burners each one should
have its own suction line from the tank or a circulation system should be
used.
The temperature in the oil line should be kept as constant as possible. Avoid
exposing the line to excessive cold which may cause blockages.
The oil pipe and electric cable should be fitted so that the burner can be
placed on the floor for inspection of the combustion device.
Oil hoses must be of a quality designed for FAME (RME).

The table applies to oil EO1 with a viscosity of 4,4 mm2/s (cSt) with density 830 kg/m3.
Burner with preheater
Consider that on preheating the oil quantity is reduced by 5-20% depending on
- Rise in temperature at the nozzle
- Design of nozzle
- Capacity (high capacity - small difference)
- Expect the output from the burner to reduce by 10–20% when fuelled by FAME (RME) due to the lower energy
content of the oil.

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.
