General
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 lue 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.
A whistling sound may be heard which can be
eliminated or reduced as follows: Increase the nozzle
assembly adjustment somewhat. The CO2-content and
consequently the air volume will then 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 eficiency but also the risk of condensation
in the chimney. The risk increases if the area of the
chimney lue is too large. The temperature of the lue
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 lue gases
during operation and dries them up during
standstill)
• Increase the oil quantity
• Raise the lue 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.
Firing with EO1 should be conducted the last few hours
at the end of the iring season.
Installation instructions
General installation instructions ac company the burner
and should be left in a prominent place adjacent to the
burner.
Oil supply
The oil line should be dimensioned in accordance with
the pump manufacturer´s instruction. A ilter 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 itted so that
the burner can be placed on the loor for inspection of
the combustion device.
Oil hoses must be of a quality designed for FAME (RME).
