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 combu-
stion.
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 experien-
ced personnel.
INSTALLATION INSTRUCTIONS
General installation instructions ac-
company the burner and should be
left in a prominent place adjacent to
the burner.
ADJUSTMENT OF BURNER
The burner is from the factory pre-set
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 CO
2
or
O
2
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 adjust-
ment 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 fol-
lows: Increase the nozzle assembly
adjustment somewhat. The CO
2
-con-
tent and consequently the air volume
will then be reduced.
CONDENSATION IN CHIMNEY
A modern burner works with less ex-
cess air and often also with smaller
nozzles than older models. This
increases the efficiency but also the
risk of condensation in the chimney.
GENERAL INSTRUCTIONS
MAINTENANCE
The boiler/burner should be examined
regularly for any signs of malfunction or
oil leakage
OIL SUPPLY
The oil line should be dimensioned in
accordance with the pump
manufacturer´s instruction. In the
suction line to the burner a filter should
be mounted to prevent any particles
in the oil from reaching the burner. 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 of paraf-
fin deposits.
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.

B Adjustment Stage 3.
The risk increases if the area of the
chimney flue is too large. The tempera-
ture 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.
