Natural Convection For The Insert - BOREAL RADIOFRÉQUENCE Série Instructions D'installation, D'utilisation Et D'entretien

In the drawing are represented the basic requirements for the chimney installation of the stove:
EN
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 you can see the requirements for a correct installation.

NATURAL CONVECTION FOR THE INSERT

In the case of the Insert 7, when it is inserted into a pre-existing
coating or chimney, it is essential that the space included
between the upper part, the sides of the insert and the
non-combustible material of the hood (which closes the base
of the flue pipe), are constantly ventilated. For this reason,
it is necessary to allow an air intake through the lower part
of the coating (fresh air inlet) and an outlet in the upper part
(hot air outlet) through the hood. With this we will improve
the operation of the set since we are establishing a natural
convection circuit.
The measures that should be respected are:
• The lower part (cold air inlet) should have a minimum
total area of 550 cm
• The upper part (hot air outlet) should have a minimum
total area of 500 cm
It is important to clarify that this natural convection is totally
independent of the primary air intake.
