CHIMNEY OR CHIMNEY FLUE

· The chimney or chimney flue must respect the following requirements:

- It must seal in the exhaust fumes, be water-tight and suitably insulated and isolated in accordance with the conditions of use (UNI

9615);

- It must be made in materials that can resist normal mechanical tress, heat and the action of the products of the combustion and

possible condensation;

Must be prevalently vertical with deviations of not more than 45° from the axis;

It must be adequately distanced from combustible or inflammable materials with a cavity or else suitable insulation

The internal section must preferably be circular; squared or rectangular sections must have rounded corners with a radius not less
than 20 mm;

It must have a constant internal section that is free and independent;

Rectangular sections must have a maximum ratio between sides of 1:5;

The indications given by the manufacturer on the section and construction characteristics of the chimney/flue must be followed. For
particular sections, section or routing variations, check the working efficiency of the exhaust fumes system using the fluidodynamic
calculation (UNI 9615).

It is recommended that the smoke duct be fitted with a chamber for the collection of solid material and any condensation, located under
the opening of the smoke duct so that it can easily be opened and inspected through the airtight inspection door.

In case of a fire in the chimney flue, use suitable systems to suffocate the flames (e.g. use a powder or carbon dioxide extinguisher)
and request an intervention of the Fire Brigade.

CONNECTION OF THE APPLIANCE TO THE CHIMNEY FLUE AND EVACUATION OF COMBUSTION PRODUCTS (see legislation UNI
10683)

· The connection between the appliance being used and the chimney flue must receive exhaust fumes from one heat source only.
· An appliance can consist of a fireplace and cooking oven with a single exhaust point to the chimney for which the manufacturer must

provide the construction characteristics of the connections to the smoke ducts.

· It is forbidden to convey exhaust from hoods above cooking appliances in the same smoke duct.
· The discharge towards closed spaces is forbidden, even if they have an open ceiling.
· The direct discharge of exhaust products must be envisaged on the roof and the chimney flue must have the previously mentioned

features.

CHIMNEY COWL

· The chimney cowl must have the following features:

It must have an internal section equal to that of the chimney flue;

The useful outlet section must not be less than twice that of the chimney flue;

It must be built so that it prevents the entry into the chimney of rain, snow and foreign bodies and in such a way that even in the case
of winds blowing from all sides or angles the discharge of the combustion products is ensured;

It must be positioned so that it guarantees an adequate dispersion and dilution of the combustion products and in any case, outside
the backflow zone where the formation of counter pressure can occur. This zone has different size and formation depending on the
inclination angle of the roof and therefore it is essential that the minimum heights indicated in the designs (fig.6) are respected.
