Installer/Servicer notes for the use of Gas oil with Bio blends up to 30% where gas oil use is permitted by
the appliance Manufacturer
During the burner installation, check that the gasoil and bio
fuel blends are in accordance with Riello specifications
(please refer to the chapters "Technical Data" and "Guid-
ance for the use of bio fuel blends up to 30%" within the
burner technical manual).
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 bio fuels, 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. Riello recommends that existing oil
storage tanks are cleaned, inspected and any traces of
water are removed BEFORE bio fuel is introduced (Contact
the tank manufacturer or oil supplier for further advice). If
these recommendations are not respected 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. Riello recommends a good quality bio com-
patible oil filter at the tank and a secondary 60 micron filter
are used to protect the burner pump and nozzle from con-
tamination.
The burner hydraulic components and flexible oil lines must
be suitable for bio fuel use (check with Riello if in doubt).
Riello have carefully chosen the specification of the bio com-
patible components including the flexible oil lines to protect
the pump, safety value and nozzle. The Riello warranty is
dependent upon the use of Riello genuine components
including the oil lines, being used. The burner must be com-
missioned and combustion parameters 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 Bio fuel use, oil filters
are inspected and replaced every 4 months. More regularly
where contamination is experienced.
During extended periods of non operation and/or where
burners are using oil as a standby fuel, it is strongly recom-
mended that the burner is put into operation for shorts peri-
ods at least every three months.
