Страница: 7 / 14

BASIC SETTINGS
Pump pressure: 10 bar.
The fan pressure is measured in the test
nipple (se under Description
Components pos. 4) with a U-tube or a
suitable pressure gauge.
AIR ADJUSTMENT
On all burners the air adjustment can
be made with or without the cover
fitted. Final fine adjustment must be
made with the cover on.
MAINTENANCE
The boiler/burner should be examined
regularly for any signs of malfunction or
oil leakage.
FASTENING OF THE BURNER TO
THE BOILER (FLANGE)
GENERAL INSTRUCTIONS
This increases the efficiency but also
the risk of condensation in the chimney.
The risk increases if the area of the chimney
flue is too large. The temperature of the
flue gases should exceed 60°C measu-
red 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 remo-
ving 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 the boiler/
burner being kept free of combustible
material.

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 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. 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 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 follows:
Increase the nozzle assembly adjust-
ment somewhat. The CO
2
-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.
