Connection Of The Stove To The Chimney; Coating And Installation Of The Insert - BOREAL E4000 Serie Instrucciones De Instalación, Uso Y Mantenimiento

The flue must be away from flammable or combustible materials through an appropriate insulation or an air chamber. In the case that they pass through
flammable materials compounds, they should be eliminated.
Inside, it is forbidden that there are pipes of installations or air abduction channels. It is also prohibited to do mobile or fixed openings for connecting
other different equipments.
If we use metallic pipes inside a masonry duct, it is essential that they are well insulated and with appropriate materials (insulating fibre coatings) in order
to avoid the deterioration of the masonry or the interior coating.
(1) In the case that there are chimneys placed side by side, one
of them must exceed to the other at least 50 cm in order to avoid
pressure movements among them

CONNECTION OF THE STOVE TO THE CHIMNEY

The connection to the stove for the smoke evacuation must be done with rigid aluminized steel pipes or stainless steel pipes.
It is forbidden the use of flexible metallic pipes or fibre cement pipes because they damage the safety of the connection because they are subject to
jerks and breaks, which causes smoke looses.
The chimney must be fixed hermetical to the smoke outlet of the stove. It should be rectilinear and with a material that supports high temperatures
(minimum 400ºC). 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. This service is assured by the
pipes complying with DIN 1298.

COATING AND INSTALLATION OF THE INSERT

When the insert is installed in a facing or an old chimney it is essential the space among the top and the sides of the equipment and the fireproof
material of the hood (which block the base of the chimney) will be 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) by the hood. The function will be improved due to there is a natural convection circuit. Every one
of these openings must be free and not blocked with a surface of 3 dm2 at least (for example, grille 30 x 10 cm.).
(1) The chimney can't have obstacles around 10 m towards
walls or trees. Otherwise, raise it at least 1 m above the obstacle.
The chimney must exceed the top of the roof at least 1 m.
