SPARE PARTS
In the event of a malfunction, consult the retailer who shall forward the call to the Technical Assistance Department.
Only use original spare parts. The retailer or service centre can provide all necessary information regarding spare parts. We do not
recommend waiting for the parts to get worn out before having them replaced. It is crucial to perform regular maintenance checks.

All parts must be replaced with original spare parts.
Information for management of waste electrical and electronic equipment containing batteries and
accumulators
This symbol appears on the product, on the batteries, on the accumulators or on their packaging or on their documentation; it indicates
that the product and the batteries or the accumulators included must not be collected, recycled or disposed of with household waste at
the end of their service life.
Improper management of waste electrical and electronic equipment, batteries or accumulators can cause the hazardous substances
contained within to leak out. In order to avoid harming the environment or health, the user is required to separate this equipment, and/
or the batteries or accumulators included, from other types of waste and deliver them to the local collection centre. The distributor can
be asked to collect the waste electrical and electronic equipment under the conditions and according to the procedures laid down by
Legislative Decree 49/2014.
Separate collection and correct treatment of waste electrical and electronic equipment, batteries and accumulators contribute to
conserving natural resources, respect for the environment and ensure the protection of health.
For more information on collection centres for waste electrical and electronic equipment, batteries and accumulators, contact the
competent public Authorities for issue of the authorisations.
WHY SEALED
Products built with a perfectly sealed structure do not consume the room’s oxygen but draw all the air from the outer environment (if
suitably ducted) and may therefore be installed in all houses that require a high degree of insulation such as “passive” or “high energy
eciency”houses. Thanks to this technology there is no risk of smoke emissions in the room, hence no air inlets and relevant ventilation
grilles are required in the installation premises.
Consequently, there will be no more draughts of cold air in the room, which would otherwise make it less comfortable and reduce the
overall eciency of the system.The sealed stove may even be installed in the presence of forced ventilation or in premises that might have
negative pressure with respect to the outside.

2014/53/EU (RED – Radio Equipment directive)
2011/65/EU (ROhS)
Having specied the above, we highlight and report that:
•This manual and technical data sheet, also available on our website, bear all of the specic indications and necessary and
essential information to choose the product, to install it correctly and to properly size the smoke expulsion system;
•the Products must be installed, controlled and serviced by qualied personnel, according to the instructions in this manual
and in compliance with local laws and installation and maintenance standards in force in individual countries, so as to provide an
ecient heating system, properly sized according to the needs of the home;
•if the Products are thermally stressed, constantly operating for several hours at high power (e.g. 3, 4 hours a day at outputs P4
or P5), we recommend more frequent cleaning and reducing the interval between routine maintenance operations according to the
operating condition of the product. We furthermore point out that these operating conditions increase the risk of premature wear of
the product, especially those parts exposed to the direct heat of the re (e.g. combustion chamber), the original condition of which
can undergo modications and deterioration which, among other things, could generate noise during operation of the unit due to
mechanical expansion.
The manufacturer will not be held liable if the above information is ignored.
We therefore recommend, in addition to complying with the cleaning, routine and extraordinary maintenance instructions provided, to
make meticulous use of the unit using the intended Timer and modulation programs, to correctly manage the internal temperature of
the structure.
