flue is prohibited.
Running other air ducts and installation pipes inside the exhaust pipes, even if oversized, is forbidden.
One or more airtight reading points are recommended on the flue to check emissions after installation and measure draught.
Supporting the weight of the flue with the appliance union is strictly forbidden. Use specific stands or independent supports for this
purpose.
To install other combustion devices in the same room where the appliance is installed, refer to UNI 10683 and UNI 7129 installation
regulations.
The minimum fireplace height must be over 3,0 m.
Installation of external fireplaces must be performed using insulated double-walled pipes, to prevent the formation of condensate; it must

INSTALLATION ROOM VENTILATION
According to reference regulation UNI10683, 4 Pa depression must be verified between the installation room interior and exterior.
Prepare adequate ventilation openings in the room where the product is installed to permit at least 50 m3/h clean comburent air flow
not taken from polluted rooms. The ventilation openings, if fitted with insect-proof mesh, must be easily removable and undergo periodic
cleaning to ensure clear air flow passage.
As per the fuel product exhaust system, air vents are also extremely important and must be given the
appropriate consideration and respect.
The installer is directly liable for all electrical system parts, generation hook-up to the system, ventilation and
the fume exhaust system and MUST, at the end of installation work, issue a declaration of conformity as per
Ministerial Decree 37/08.
On the other hand, the purchaser MUST assign all work to a qualified professional technician.
The device must be installed and used in accordance with all local and national laws and EC Regulations.
WARNING
It is not allowed to install coaxial systems for
the smoke output.
WARNING
The external air intakes must be made so that they cannot get accidentally covered and if they have an insect
protection mesh they must be cleaned periodically to prevent clogging with dust and dirt, especially in periods with intense
pollen concentrations.
