The flue must be away from flammable or combustible materials through an appropriate insulation or an air chamber. Inside the pipes, it is
forbidden the use of air abduction channels. It is also prohibited to do mobile or fixed openings for connecting other different equipments.
The smoke duct must be staunchness set to the equipment and it can have a maximum inclination of 45° whereby excessive deposits of
condensation produced in the initial stages of ignition and / or excessive soot formation is avoided. Moreover, it avoids the slowing down of
the smoke when it comes out.
The lack of sealing of the connection may cause the malfunction of the equipment.
The internal diameter of the connection pipe should correspond to the external diameter of the chimney of the equipment.
In drawing D12 you can see the requirements for a correct installation.

NATURAL CONVECTION FOR INSERTS
When the inserts Neva and Damasco are installed in a facing or in an old chimney it is essential that the space between the top and the sides
of the equipment and the fireproof material of the hood (which blocks the base of the chimney) are constantly ventilated. For this reason, it
is necessary to keep an fresh air entry on the bottom of the facing and an exit on the top (hot air exit) on the hood. The aim is to improve the
operation because there is a natural convection circuit (see drawing D13).
The measures that need to be respected are:
•
The bottom side (cold air intake) should have a total minimal surface of 550 cm2.
•
The upper side (hot air outlet) should have a total minimal surface of 500 cm2.
It is important to clarify that this natural convection is completely independent from the primary air intake.
5.5
CHIMNEY COWL
The chimney draft also depends on the chimney
cowl. Therefore, in case of an artisanal chimney
cowl, it is indispensable that the exit section is
twice the inside section of the smoke duct. The
smoke exit will be assured even in presence or air
(see drawing D14).
The chimney cowl must comply with the following
requirements:
•
It must have the same interior section of the chimney.
•
It must have an usable exit section that is two times the one of the interior of the chimney.
•
It must be constructed so that the rain, snow or any other objet do not enter inside.
•
It must be easily accessible in order to do servicing and cleaning tasks.
