Flame signal
When operating at high power or low air excess and HVO/XTL is used as fuel,
the ame signal may deteriorate (blue ame), the signal lamp in the reset
button ashes green.
By lowering the air velocity or changing the ame detector to QRC1 A1, the
ame signal can be improved.

4. Installation
4.1 General instructions
Oil burners must be installed in accordance with local regulations. The installer
must therefore be knowledgeable of the regulations pertaining to oil and
combustion.
Only oil suitable for the burner must be used and then in combination with a
suitable oil lter installed before the burner’s oil pump.
If the burner is replacing an existing burner, ensure that the oil lter is
replaced or cleaned. Installation may only be performed by qualied
personnel.
Care should be taken by the installer to ensure that electrical cables and oil
lines are not pinched or otherwise damaged during installation or servicing.
4.2 Inspection and maintenance
The system must be maintained at the interval specied in the service
schedule. If the burner is in a dirty environment, service should be done at
more frequent intervals.
4.3 Start-up
In order to obtain the correct setting, a ue gas analysis and temperature
measurement must be carried out. Otherwise, there is a risk of soot build up,
poor eciency or condensation in the chimney. The system must be ne-tuned
at start-up. The temperature in the chimney at a depth of 0.5 m must be at
least 60 °C to prevent condensation.
4.4 Delivery inspection
Make sure everything is delivered and the goods have not been damaged
during transit. If something is wrong with a delivery, report it to the supplier.
Transport damage must be reported to the shipping company.
4.5 Preparing for installation
Check that the burner’s dimensions and capacity range are suitable for the
relevant boiler. The power data on the rating plate refers to the burner’s
minimum and maximum power.

4.6 Oil distribution
In order to achieve good reliability, it is important that the oil distribution
system is designed correctly.
Take the following into account:
• Selection of pipe diameter, pipe length and height difference; see
Pump instruction.
• Pipelines are to be laid with the fewest possible number of glands.
• The pipes are to be laid so that the oil supply hoses are not subjected
to tensile stresses or become excessively bent when the burner is
swung out or removed for servicing.
• The oil lter should be installed so that the lter cartridge can easily
be replaced or cleaned.
• Parts in contact with oil must be selected in materials that are capable
of withstanding the medium’s physical properties.
• When installing oil hoses, check that the inlet and return hoses are
tted to the appropriate connection on the oil pump. The hoses must
be located so that they do not bend or become subject to tensile load.
• Bleed the oil system. The oil pump/oil preheater may be damaged if
run dry. The vacuum in the suction line should not fall below 0.3 bar
during start-up.
4.7 Electrical connection
• Before work on the electrical connection, the current must be
disconnected so that the installation is isolated.
• Electrical connection must be done in accordance with the applicable
regulations.
• Burners must be connected to an all-pole switch.
• Connection must conform to the wiring diagram.
• Use appropriately sized fuses.

5. Mounting of burner on boiler
1. Remove fan housing from  xing  ange.
2. Remove the brake plate from the oil line.
3. Install the selected nozzles, (see Technical data).
4. Install the brake plate on the oil line.
5. Remove the  ame tube from the  ange.
6. Install the  ange with gasket on the boiler.
7. Install  ame tube, be sure to install the drainage hole
downwards (not available on all  ame tubes) so that any oil
spills can drain out.
8. Insulate between  ame tube and boiler door for reduced heat
radiation.
9. Install the fan housing on the  ange and lock with nuts.
10. Connect oil lines to the pump, (see chapter Service).
11. Connect the burner electrically, (see chapter Service).
5.1 Check oil line seals
When the burner has been installed and put into operation, the
tightness of the various coupling elements should be checked, in case
of leakage - retighten the coupling elements.

5.2 Example of Basic settings
Basic settings should only be seen as setting values to get burner to start
and establish ame. Once the burner has started and established ame, it is
necessary to adjust the settings so that they are adapted to the installation and
the fuel used.
