Information and general warnings
Guarantee and responsibilit The manufacturer guarantees its new products from the installation date, in accordance with the regulations in force and/or the sales contract. At the moment of the first start-up, check that the burner is integral and complete. In particular, the rights to the guarantee and the responsibility will no longer be valid, in the event of damage to things or injury to people, if such damage/injury was due to any of the following
causes: incorrect installation, start-up, use and maintenance of the burner; improper, incorrect or unreasonable use of the burner; intervention of unqualified personnel; carrying out of unauthorised modifications on the equipment; use of the burner with safety devices that are faulty, incorrectly applied and/or not working; installation of untested supplementary components on the burner; powering of the burner with unsuitable fuels; faults in the fuel supply system; continuation of use of the burner when a fault has occured repairs and/or overhauls incorrectly carried out; modification of the combustion chamber with inserts that prevent the regular development of the structurally established flame; insufficient and inappropriate surveillance and care of those burner components most likely to be subject to wear and tear; the use of non-original components, including spare parts, kits, accessories and optional; force majeure The manufacturer furthermore declines any and every responsibility for the failure to observe the contents of this manual. Riello warranty is subject to correct burner, appliance and application matching, and set up in line with Riello’s instructions and guidelines. All components within the hydraulic circuit suitable for
bio fuel use and supplied by Riello will be identified as Bio compatible. No warranty is given in relation to the use of components.
which are not so identified with bio fuel blends. If in any doubt please contact Riello for further advice. If any Riello burners are used with fuel with a bio content >10% then the components within the hydraulic circuit maybe affected
and are not covered under warranty. The hydraulic circuit consists of;
– Hydraulic ram (where applicable)
– Valve block
– Flexible oil lines (considered as a consumable component)
1. Irrespective of any warranty given by Riello in relation to normal use and manufacturing defects, when fuels not
meeting the relevant standards are used, or where fuel storage issues have not been addressed correctly, or the equipment used is not compatible, 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.
2. Riello have carefully chosen the specification of the bio compatible 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.
3. Riello warranty does not cover defects arising from incorrect commissioning or servicing by non Riello employed service engineers, and any issues impacting the burner arising from external site related issues. Guidance for the use of bio fuel blends up to 10%
Background With increasing focus on renewable and sustainable energy requirements, Bio fuel usage is set to increase. Riello is committed to promoting energy conservation and the use of renewable energy from sustainable resources including liquid bio fuels, however 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 Ester) liquid Bio fuel is critical to reliable equipment operation.
It is a minimum requirement that the fuel blend (up to 10% Bio) is obtained with gasoil in accordance with the relevant EN standards, regional regulations and FAME in accordance with EN 14214. It is also important that the fuel blends meet the requirements 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 storage 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 appliances and installation applicable.
Irrespective of any warranty given by Riello in relation to normal
use and manufacturing defects, when fuels not meeting the relevant standards are used, or where fuel storage issues have not been addressed correctly, or the equipment used is not compatible, 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.
Failure to observe the information given in this
manual, operating negligence, incorrect installation and carrying out of non authorised modifications will result in the annulment by the manufacturer of the guarantee that it supplies with the burner. 20033283 6 GB Information and general warnings 2.3.1 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 compatible with Bio fuels. For all installations, there must be a good quality bio compatible oil filter at the tank and then a secondary filter of 100 Microns protecting the burner from contamination.
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 hydroscopic nature of Bio fuel, it will effectively clean the
tank, absorb water present which in turn will result in equipment failure that is not covered by the manufacturer’s warranty.
Depending on the capacity of the oil storage tank and oil usage, fuels may remain static within the tank for some considerable time and so Riello recommends that the oil distributor is consulted regarding the use of additional Biocides within the fuel to prevent microbial growth from occurring within the tank. Riello suggests that fuel suppliers and or service companies are contacted for guidance on fuel filtration. Special attention should be applied to duel fuel applications where oil may be stored for long periods of time The burner must be set according to the appliance application and commissioned checking that all combustion parameters are as recommended in the appliance technical manual.
Riello recommends that the in line and burner oil pump filters are inspected and if required replaced at least every 4
months during burner use, before the burner start-up following 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. 2.3.2 Product Disclaimer Statement

7 GB 20033283 Safety and prevention 3.1 Introduction The burners have been designed and built in compliance with
current regulations and directives, applying the known technical rules of safety and envisaging all the potential danger situations. It is necessary, however, to bear in mind that the imprudent and clumsy use of the equipment may lead to situations of death risk for the user or third parties, as well as the damaging of the burner or other items. Inattention, thoughtlessness and excessive confidence often cause accidents; the same applies to tiredness and sleepiness.
It is a good idea to remember the following: The burner must only be used as expressly described. Any other
use should be considered improper and therefore dangerous. In particular: it can be applied to boilers operating with water, steam, diathermic oil, and to other uses expressly named by the manufacturer; the type and pressure of the fuel, the voltage and frequency of the electrical power supply, the minimum and maximum deliveries for
which the burner has been regulated, the pressurisation of the combustion chamber, the dimensions of the combustion chamber and the room temperature must all be within the values indicated in the instruction manual.
Modification of the burner to alter its performance and destinations is not allowed.
The burner must be used in exemplary technical safety conditions. Any disturbances that could compromise safety must be quickly eliminated. Opening or tampering with the burner components is not allowed, apart from the parts requiring maintenance. Only those parts detailed as available as spare parts by the Manufacturer can be replaced Safety warnings The dimension of the boiler’s combustion chamber must respond to specific values, in order to guarantee a combustion with the lowest polluting emissions rate. The Technical Service Personnel will be glad to give you all the imformation for a correct matching of this burner to the boiler. This burner must only be used for the application it was designed for The manufacturer accepts no liability within or without the contract for any damage caused to people, animals and property due to installation, adjustment and maintenance errors or to improper use.
