2.3 Guidance for the use of bio fuel blends up to 30% where gas oil use is permitted by the appliance
Manufacturer
Background
With increasing focus on renewable and sustainable energy re-
quirements, Bio fuel usage is set to increase. Riello is committed
to promoting energy conservation and the use of renewable en-
ergy from sustainable resources including liquid bio fuels, howev-
er there are some technical aspects that must be considered at
the planning stage of using such fuels to reduce the potential for
equipment failure or the risks of fuel leakage.
Liquid Bio fuel is a generic description used for oil that can come
from numerous feed stocks including recycled cooking oils.
These types of oils have to be considered and treated differently
from standard mineral or fossil fuels, as they are generally more
acidic, hydroscopic and less stable.
Due to this, a holistic approach is needed from the specification
of the liquid Bio fuel, the storage of the fuel, its oil supply line and
ancillary equipment, and very importantly the oil filtration and the
burner itself. The specification for FAME (Fatty Acids Methyl Es-
ter) liquid Bio fuel is critical to reliable equipment operation.
It is a minimum requirement that the fuel blend (up to 30% Bio) is
obtained with gas oil in accordance with the relevant EN stand-
ards, regional regulations and FAME in accordance with BS EN
14214. It is also important that the fuel blends meet the require-
ments related to operational environment conditions within the
relevant EN standards.
When choosing your Riello oil products where you know Bio fuels
will be in use, please make sure that a Bio compatible burner and/
or components have been supplied. If an existing burner is to be
used with a liquid Bio fuel then a kit may be required to make it
compatible and the guidance notes enclosed concerning oil stor-
age and filtration must be adhered to. The end user is responsible
for the thorough verification of the potential risks associated with
the introduction of a bio fuel blend and the suitability of the appli-
ances and installation applicable.
Irrespective of any warranty given by Riello in relation to normal
use and manufacturing defects, when fuels not meeting the rele-
vant standards are used, or where fuel storage issues have not
been addressed correctly, or the equipment used is not compat-
ible, if failures occur which are directly or indirectly attributed to
such issues and/or to the non-observance of this guidance, then
no warranty or liability is implied or accepted by Riello.

Information and general instructions

To ensure consistency, the supplier of the fuel must be able to
demonstrate compliance with a recognised Quality Control and
management system to ensure high standards are maintained
within the storage, blending and delivery processes.
The installation oil storage tank and its ancillaries must also be
prepared BEFORE liquid Bio fuel is introduced.
Checks and preparation should include:
 For new installations, make sure that all materials and seals
in the oil storage and supply line to the burner are compati-
ble with Bio fuels. For all installations, there must be a good
quality bio compatible oil filter at the tank and then a second-
ary filter of 60 Microns protecting the burner from contamina-
tion.
 If an existing oil storage tank is to be used then in addition to
the materials checks as detailed above, it will be essential
that the tank is first inspected for condition and checked for
water or other contamination. Riello strongly recommends
that the tank is cleaned and oil filters replaced prior to Bio
fuel delivery. If this is not completed then due to the hydro-
scopic nature of Bio fuel, it will effectively clean the tank,

Although the information and recommendations (hereinafter "In-
formation") in this guidance is presented in good faith, believed to
be correct and has been carefully checked, Riello (and its subsid-
iaries) makes no representations or warranties as to the com-
pleteness or accuracy of the Information. Information is supplied
upon the condition that the persons receiving same will make
their own determination as to its suitability for their purposes prior
to use. In no event will Riello (and its subsidiaries) be responsible

or reliance upon Information.
Other than set forth herein, Riello (and its subsidiaries) makes no
additional warranties with respect to the bio compatible burner,
either express or implied, including that of merchantability or fit-
ness for a particular purpose or use.
In no event shall Riello (and its subsidiaries) be liable for any in-
direct, incidental, special or consequential damages including,
without limitation, loss of profits, damages for loss of business

usage, fuels may remain static within the tank for some con-
siderable time and so Riello recommends that the oil distrib-
utor is consulted regarding the use of additional Biocides
within the fuel to prevent microbial growth from occurring
within the tank. The Department of Transport suggest when
using fuels with a bio fuel content within "Stationary Equip-
ment" that the content of tanks is turned every six months or
in any event no less than every twelve months to help pre-
vent blockages to filters. Riello suggests that fuel suppliers
and or service companies are contacted for guidance on fuel
filtration. The extract detailed above referencing Section 4 -

are inspected and if required replaced at least every 4
months during burner use, before the burner start-up follow-
ing a long period of discontinue operation and even more
frequently where contamination has occurred. Particular
attention is needed when inspecting and checking for fuel
leakages from seals, gaskets and hoses.
