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
of the burner.
If the burner is replacing an existing
replaced or cleaned. The installation
must only be undertaken by expe-
rienced personnel. Care should be
taken by the installer to ensure that no

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 manufactur-
ers instructions.These must include
average water temperature and CO2
or O2concentration.
To adjust the combustion device,
start by increasing the air volume
and the nozzle assembly somewhat.
with excess air and smoke number
0. Reduce the nozzle assembly ad-
justment 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.
Awhistling sound may be heard which
can be eliminated or reduced as fol-
lows: Increase the nozzle assembly
adjustment somewhat. The CO2-con-
tent and consequently the air volume
will then be reduced.
GENERAL INSTRUCTIONS
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.
The risk increases if the area of the
-
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
removing turbulators, if any, in the
boiler.

malfunction or oil leakage.
Oil supply
The oil line should be dimensioned
in accordance with the pump manu-
facturer´s instruction. In the suction

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
The oil pipe and electric cable should

Adjustment of nozzle assembly
Loosen the locking screw B and adjust
the nozzle assembly to the desired
position. Lock the screw B again.
Air adjustment 0-10
Loosen the stop screw B and turn the
knob along the scale to the desired
position and tighten the screw. Check
gas analysis.
