Connection Of The Stove To The Chimney - Bronpi SYDNEY Instrucciones De Instalación, Uso Y Mantenimiento

D34
A big section of the chimney (for example, diameter of the pipe superior
to the one recommended) may results in a volume too large to be heated
and, therefore, it can cause difficulties for the proper operation of the
equipment. In order to avoid this problem, it is necessary to enclose
the chimney in its entire length. However, a small section (for example,
diameter of the pipe inferior to the one recommended) may cause a
reduction of the draft.
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.
4.1.

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.

(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
INSTALLATION, OPERATING AND SERVICING INSTRUCTIONS
(1) Stainless steel AISI 316 chimney with double insulated
chamber and material resistant up to 400°C. Efficiency
100% optimum.
(2) Traditional clay chimney with square section and
holes. Efficiency 80% optimum.
(3) Chimney with refractory material and double
insulated chamber and exterior coating made of
lightweight concrete. Efficiency 100% optimum.
(4) Avoid chimneys with rectangular interior section
different to the one of the drawing. Efficiency 40% poor.
Not recommended
D35
D38
(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.
