WARRANTY
Certicate of warranty
Ravelli thanks you for the trust granted with the purchase of one of its products and invites the purchaser to:
• read the installation, use and maintenance instructions for the product;
• read the warranty conditions contained below.
Warranty conditions
The warranty for the Customer is acknowledged by the Dealer under the terms of law.
The Dealer acknowledges the warranty only if the product has not been tampered with and only if it has been installed in accordance with
the Manufacturer’s instructions.
The limited warranty covers manufacturing material defects, as long as the product has not broken sue to an incorrect use, negligence,
incorrect connection, tampering, installation errors.
The warranty becomes null and void even if only one requirement in this manual is not complied with.
The following are not covered by warranty:
• the combustion chamber refractory stones;
• the door glass;
• the gaskets;
• the paint job;
• the stainless steel or cast iron combustion grille;
• the resistance;
• the Majolica cladding;
• the aesthetic parts;
• any damages caused by unsuitable installation and/or use of the product and/or shortcomings on the part of the customer.
The use of poor quality pellet or any other unauthorised fuel may damage the product’s components, cause its warranty to be voided and
as a result eliminate the connected manufacturer liability.
It is therefore recommended to use good quality pellet that fulfils the requirements listed in the dedicated chapter.
All damages caused by transportation are not recognised, for this reason it is recommended to carefully check goods upon receipt,
immediately warning the reseller of any damage.
Registration of warranty
To activate the warranty, it is necessary to register the product on the Guarantee Portal on the website
www.ravelligroup.it, by entering your data and the purchase receipt.

SAFETY MEASURES
General safety warnings
📌Read this instructions manual carefully before stove installation
and use. Failure to observe the instructions set forth herein
can void the warranty and/or cause damage to property and/
or people.
⚠ Stove installation, system verification, operation verification
and initial calibration must be carried out exclusively by qualified
and authorised staff.
⚠ The stove needs to be connected to a single chimney that
guarantees the draught declared by the Manufacturer and
observes the installation regulations that apply to the installation
site.
⚠ The room where the stove is installed must have an air intake.
⚠ The stove must not be used as an incinerator or differently
from its purpose

⚠ Do not use any fuel other than fire pellet. It is strictly forbidden
to use liquid fuels.
⚠ It is prohibited to use the stove with the door or ash drawer
open or the glass broken.
⚠ Do not touch the hot surfaces of the stove without suitable
protective equipment, to avoid getting burned. When it is
running, the outer surfaces reach hot temperatures to the
touch.
⚠ It is forbidden to make unauthorised changes to the stove.
⚠ Before using the stove it is necessary to know the position and
function of the controls.
⚠ If the chimney catches fire you must call the fire brigade.
⚠ Only use original spare parts. Any tampering and/or
replacements that have not been authorised by Ravelli can
pose a danger to the user’s safety.
⚠ In the event of particularly adverse weather conditions, the
safety systems could intervene and switch off the stove. In any
case, doe not disable the safety systems.
Residual risks
The stove was designed so as to guarantee the user’s essential
safety requirements.
Safety was integrated into the stove’s design and construction as
much as possible.
For every residual risk there is a description of the risk and the zone
or part that is applies to (unless the risk applies to the entire stove
overall). Procedure-related information is also provided on how to
avoid the risk and on the correct use of the personal protective
equipment required by and made compulsory by the Manufacturer.

Characteristics of the fuel
Wood pellet is a fuel made of pressed wood sawdust, often recovered from processing scraps of carpentries. The material used
cannot contain any extraneous substance such as, for example, glue, lacquer or synthetic substances.
The sawdust, once it has been dried and cleaned from impurities, is pressed using a die with holes: as a result of high pressure, the
sawdust heats up by activating the natural wood binders; this way the pellet maintains its shape even without adding articial
substances.
Wood pellet density varies based on the type of wood and can exceed that of natural wood by 1.5 - 2 times.
The cylinders have a diameter of 6 mm and a variable length between 10 and 40 mm.
Their density is equal to approximately 650 kg/m3. Due to their low water content (< 10%) they have a high energy content.
The UNI EN ISO 17225-2:2014 standard (that replaces the EN PLUS standard) denes pellet quality by specifying three classes: A1,
A2 and B. Maintain fuels and other ammables at a suitable distance.
Ravelli recommends using wood pellet classied A1 and A2 according to the EN ISO 17225-2:2014 standard, or certied DIN PLUS
(more restrictive than the A1 class) or ONORM M 7135. Pellet may be light or dark coloured, it is normally bagged into bags that show
the name of the producer, the main characteristics and classication according to standards.
📌Pellets must be transported and stored in a dry area. Upon contact with humidity they swell and become unusable
📌It is therefore necessary to protect them from humidity, both during transport and during storage.
Non-permitted fuels
We recommend not using the following materials as fuel:
• wood
• treated wood (painted, lacquered, glued wood etc.);
• sawdust or chips
• liquid fuel
• coal or other fossil fuels
• plastic and derivatives
• treated paper and cardboard
• waste
• fuels that release toxic or polluting substances
Using these fuels, on top of being forbidden due to the emission of polluting and harmful substances, causes the stove to deteriorate
more rapidly and debris to accumulate in the stove and in the smoke evacuation system, thereby reducing performance and safety.
📌The gases produced by these fuels are dangerous for the environment and for your health!
📌Using fuel that is not compliant with the above will void the warranty.
