Every appliance must have a vertical ue pipe operating by natural
draught to discharge the combustion gases outdoors.
The ue must:
- comply with regulations in force in the place of installation of the
appliance;
- be tight to the products of combustion, waterproof, suitably insulated,
made with materials resistant to the corrosion of the gases and to
stress;
- be connected to just one stove, rebox or extraction hood (Fig. 2);
- be properly sized, with constant free internal section, equal to or
greater than the diameter of the ue pipe of the stove and at least 3.5
m in length (Fig. 2);
- be mainly in a vertical position with a deection from the axis of no
more than 45° (Fig. 2);
- be at a suitable distance from combustible or ammable materials,
ensured by an air gap or suitable insulating material (Fig. 3);
- be of uniform internal section, preferably round. Square or rectangular
sections must have rounded corners with a radius of at least 20 mm
and a maximum ratio between the sides of 1.5 (Fig. 4);
- the walls must be smooth if possible and without narrowing; bends
must be regular and without discontinuity (Fig. 6).
d It is forbidden to make xed or mobile apertures on the ue
pipe to connect appliances other than the one to which it is
already connected.
d It is forbidden to pass other air ducts or service pipes inside
the ue pipe, however large it is.
a If the ue pipe is an incorrect size or installed other than in
compliance with the above instructions, Gruppo Piazzetta
S.p.A. cannot be held liable for malfunctioning of the product,
damage to property or injury to persons or animals.

easily inspected by means of an airtight door. (Fig. 1)
