GENERAL INSTRUCTIONS
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 regula-
tions relating to oil and combustion.
Only oil suitable for the burner should
be used and then in combination with
a suitable oil fi lter before the oil pump
of the burner.
If the burner is replacing an existing
burner make sure that the oil fi lter is
replaced or cleaned. The installation
must only be undertaken by expe-
rienced 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.
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 the boiler
manufacturer´s instructions.These
must include the checking of fl ue gas
temperatures, average water tem-
perature 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 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 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 follows: Increase the nozzle as-
sembly adjustment somewhat. The
CO
2
-content and consequently the air
volume will then be reduced.
Oil supply
The oil line should be dimensioned
in accordance with the pump
manufacturer´s instruction. In the
suction line to the burner a fi lter 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 circula-
tion 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 paraffi n
deposits.
The oil pipe and electric cable should
be fi tted so that the burner can be
placed on the fl oor for inspection of
the combustion device.
Condensation in chimney
A modern burner works with less ex-
cess air and often also with smaller
nozzles than older models. This
increases the effi ciency but also the
risk of condensation in the chimney.
The risk increases if the area of the
chimney fl ue is too large. The tempera-
ture of the fl ue 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
fl ue gases during operation and dries
them up during standstill)
Increase the oil quantity
Raise the fl ue gas temperature by re-
moving 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.
