Chimney - Bio Bronpi Berta Instrucciones De Instalación, Uso Y Mantenimiento

WARNING!! It is noted that both the stove and the glass get very hot and should not be touched.
In case of fire in the stove or smoke duct:
a. Close the loading door.
b. Put the fire out by using carbon dioxide extinguishers (CO2 powder).
c. Request for the immediate intervention of the fire-fighters.
DO NOT PUT OUT THE FIRE WITH WATER.

CHIMNEY

The chimney is essential for the proper functioning of the stove and primarily has two functions:
• Evacuate the smoke and the gas safely out of the house.
• Provide sufficient draught to the stove in order to keep the fire.
The draught also affects the intensity of the combustion and the heating performance of your equipment. A good draught of the fireplace
needs a reduced regulation of the air for the combustion, while a lack of draught needs a good regulation of the air for the combustion.
Therefore, it is essential that it is made perfectly and that it is subjected to maintenance operations in order to keep it in good conditions.
(Many of the claims due to malfunctioning reasons refer exclusively to a bad draught).
It is necessary to comply with the following requirements for the proper operation of the stove:
• The interior section must be preferably circular.
• It must be thermally insulated along its entire length in order to prevent condensation (the smoke is
liquefied by heat shock) and even more if the installation is outside the house.
• If we use metallic pipe for the installation outside the house, it is compulsory to use thermal insulated
pipe. It consist of two concentric pipes and, between them, there is a thermal insulator. Moreover, we will
avoid condensation problems.
• It should not have bottlenecks (enlargements or reductions) and it must be vertical with deviations not
higher that 45º.
• If it has been used previously, it must be clean.
• Respect the technical data of the instructions manual.
The optimum draught varies between 10 and 14 (Pascal). The measuring must be always made with the equipment hot (nominal heating
power). A lower value causes a bad combustion causing carbonic deposits and excessive smoke generation, having leaks and, even worse,
an increase of the temperature that could damage the structural components of the stove. When pressure exceeds 15 Pa it will be necessary
reduce it by installing an additional draugth regulator.

To check if the combustion is correct, control if the smoke out the chimney
is transparent. If the smoke is white it means that the equipment is not
properly regulated or the pellet is being used has a too high humidity.
Otherwise,if the smoke is grey or black it means that the combustion is not
completed (it is necessary a bigger amount of secondary air).
The connection of the stove 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.
Materials that are prohibited for the chimney and, therefore, damage
the proper functioning of the equipment are: fibber cement, galvanized
steel and rough and porous interior surfaces. An example of solution is
described below:
Stainless steel AISI 316 chimney with double insulated chamber and
material resistant up to 400°C. Efficiency 100% optimum (see drawing
D5).
All stoves that send smoke to the exterior should have their own chimney.
Never use the same chimney for several equipments at the same time
(see drawing D6).
It is not recommended the fit in horizontals sections. The horizontal section
will not be longer than 3 meters.
