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
of the burner.
If the burner is replacing an existing
replaced or cleaned. The installation
must only be undertaken by experienced
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
accompany the burner and should be
left in a prominent place adjacent to
the 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
inaccordancewithboilermanufacturers
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 nozzle assembly somewhat.
When the burner starts it is burning
with excess air and smoke number 0.
Reduce the nozzle assembly adjust-
ment 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-content 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.
the risk of condensation in the chim-
ney. 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.
Pump adjustment
See separate description.
Air adjustment
See page "Air adjustment with
damper motor".
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 manu-
facturer´s instruction. In the suction
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 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 oil pipe and electric cable should
the combustion device.
Loosen the locking screw B and adjust
the nozzle assembly to the desired
position. Lock the screw B again.
