If it not possible to include the external air vent in the same room where the stove is installed, the hole can
be made in an adjacent room as long as it is permanently connected by means of a transit hole (15 cm
minimum diameter).
The UNI 10683 Standard FORBIDS the withdrawal of combustion air from garages, combustible
material warehouses, or from businesses with a fire hazard.
Do not connect the external air vent to the stove through piping
extraction devices inside the room, the air vents must guarantee a sufficient amount of air for
properly operating all the devices.
Only sealed equipment (e.g. C-type gas devices, as defined by the UNI 7129 C standard) or
equipment that does not depressurise the room compared to the outside environment can be housed
- whether existing or newly installed - in the room where the stove is installed.
Extractor fans can cause operating problems to the stove when they are installed in the same room or space
as the device.

Flue and connection to the latter - Stack
The flue is an essential component for the stove's efficient operation
sectional area as that indicated in the stove's technical features (80 mm). Each stove must be equipped with
its own flue, without other adjoining elements (boilers, chimneys, stoves etc.). The flue dimensions are closely
related to its height, which must be measured from the stove flue gas outlet to the base of the stack. In order
to guarantee draught, the stack flue outlet surface must be twice as big as the flue cross-section.
The discharge pipe for combustion products, generated by the forced draught device, must comply with the
following requirements:
- It must seal off the combustion products, besides being waterproof and suitably isolated and insulated in
relation to the conditions of use (refer to UNI 9615);
- It must be made of suitable materials capable of withstanding normal mechanical stress, heat, and the
effects of combustion products and condensate, if any;
- It must go upwards after the vertical section, for the entire remaining part, with 5% minimum gradient; The
sub-horizontal section must not have a length greater than ¼ of the actual height of the flue or chimney,
and must not be longer than 2,000 mm;
- It must preferably have a round internal cross-section: square or rectangular cross-sections must have
rounded corners with radius not inferior to 20 mm;
- It must have a constant, free and independent internal section;
