The air vent must be installed in such a way that
it can not be blocked.

7.4 ELECTRICAL CONNECTION
The plug of the stove’s power cable must
only be connected after the installation
and assembly has been completed
of the appliance, and must remain
accessible after installation.
To make the electrical connection, proceed as
described below:
• First connect the power cable to the plug on
the back of the stove and then to a wall socket.
• Supply power to the stove by turning the switch
to position (I).
When the stove is not in use, it is advisable to
disconnect the power cable.
Take care that the power cord (and any other
cables outside the equipment) do not come into
contact with hot surfaces.
Ensure that the electrical system is grounded.
For direct connection to the mains, it is necessary
to provide a device that ensures disconnection
from the mains, with a contact opening distance
that allows complete disconnection under
the conditions of overvoltage category III, in
accordance with installation rules.
If the power supply cable is damaged, it must
be replaced by the manufacturer or its technical
assistance service or in any case by a person with
similar qualifications, so as to prevent any risk.
It is recommended that authorized personnel pay
special attention to the electrical connections
after any work on the product.
7.5 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.
