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
of the burner.
If the burner is replacing an existing
is replaced or cleaned. The installa-
tion must only be undertaken by
experienced personnel. Care should
be taken by the installer to ensure
pipes are trapped or damaged during
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 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
average water temperature and CO2
or O2concentration.
To adjust the combustion device, start
by increasing the air volume and 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 disap-
pear again. Then the volume of air
is reduced until soot occurs and in-
creased 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.
Awhistling sound may be heard which
can be eliminated or reduced as
follows: Increase the nozzle assembly

and consequently the air volume will
then be reduced.
Condensation in chimney

Oil supply
The oil line should be dimensioned

the oil from reaching the burner. If the
installation consists of several burners
each one should have its own suc-
tion 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

the risk of condensation in the
chimney. The risk increases if the area
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
them up during standstill)
Increase the oil quantity

moving turbulators, if any, in the boiler.
Instructions for use
The end user of the burner should be
instructed about the operation and
safety features of the burner.
He should also be made aware of
the importance of the area around
combustible material.
