Ducting
⚠
Comply with the standards and laws in force in the region where the product is installed.
📌
This function must be activated by a qualified technician.
To heat another room in the house break the pre-cut and connect an 80 mm diameter pipe to the outlet of the duct of the stove. The size of
the duct (length and shape) must take into consideration the residual head of the fan of the ducting shown here.
📌
Use pipe and gaskets capable of withstanding high temperatures (which can even reach 200°C): it is recommended to use
metal pipes and silicone gaskets.

📌
The ducting pipe can reach very high temperatures: it must therefore be appropriately insulated with adequate materials, at
the points which can come into contact with flammable surfaces or are sensitive to high temperatures in addition to protecting
people and pets from possible burns.
📌
If using a rigid pipe for ducting, use a 45° pipe.
When crossing through walls built with flammable materials, these materials must be protected by using insulating materials or taking
appropriate measures.
It is recommended to insulate the entire length of the ducting pipe to avoid heat dispersion.
⚠
It is compulsory to connect the stove to the duct of the house before lighting. Make sure that it is not possible to touch the fan
blades, installing the necessary safety measures (e.g.: duct grille or pipe longer than 620 mm).
The duct withdraws much air from the room where the stove is installed, releasing it in another room to be heated. This is why it is
recommended to guarantee air circulation between the room where the stove is installed and the environment heated by the duct. This
allows for ideal heating of the rooms keeping outdoor cold air from coming back in and preventing heat loss.
See the specific chapter to learn the ducting settings.
Connection of external probe or thermostat
To manage the ducting in automatic mode, connect a temperature probe (optional) or external thermostat (optional) to the “REAR” connector.
📌
Connect an open/closed external thermostat, therefore potential-free.
Testing and commissioning
Stove start-up must be preceded by testing, which includes an operational check of the following elements:
•
connection to the smoke evacuation system;
•
electrical connections;
•
operation of any connected external probes;
•
checking that all materials used to build the smoke duct, chimney and chimney pot are regulation and suitable for use.
The testing is positive only when all operational phases have been completed without any anomaly being detected.
