Installer/Servicer notes for the use of light oil with bio blends up to 10%

 When installing the burner, make sure the fuel to be used is
light oil. In the case of light oil with a bio blend up to 10%,
the latter must comply with the manufacturer's specifications
(refer to "Technical data" and "Instructions for using biofuel
blends up to 10%").
 If a bio blend is in use the installer must seek information
from the end user that their fuel supplier can evidence that
the blends of fuel conform to the relevant standards.
 Check that the materials used in the construction of the oil
tank and ancillary equipment are suitable for biofuels, If not
these must be upgraded or replaced with bio-compatible
parts.
 Particular attention should be given to the oil storage tank
and supply to the burner. The manufacturer recommends
that existing oil storage tanks are cleaned, inspected and
any traces of water are removed BEFORE biofuel is intro-
duced (contact the tank manufacturer or oil supplier for fur-
ther advice). If these recommendations are not respected

Operating position

The burner is designed to operate only in the po-
sitions 1, 2, 3 and 4.
Installation 1 is preferable, as it is the only one that
WARNING
allows the maintenance operations as described
in this manual.
The installations 2, 3 and 4 permit operation but
make maintenance and inspection of the combus-
tion head more difficult.

this will increase the risk of contamination and possible
equipment failure.
 In line oil filters should be replaced making sure that they
are bio-compatible. The manufacturer recommends a good
quality bio-compatible oil filter at the tank and a secondary
60 micron filter be used to protect the burner pump and noz-
zle from contamination.
 The burner hydraulic components and flexible oil lines must
be suitable for biofuel use (check with the manufacturer if in
doubt).
 The burner must be commissioned and combustion param-
eters set to appliance manufacturer's recommendations.
 Regularly check visually for any signs of oil leakage from
seals, gaskets and hoses.
 It is strongly recommended that with biofuel use, oil filters
are inspected and replaced every 4 months; more regularly
where contamination is experienced.
Any other positioning could compromise the cor-
rect operation of the appliance.
The installation 5 is prohibited for safety reasons.
