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 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.
4.5 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.
