Chimney - BOREAL AIRE Serie Instrucciones De Instalación, Uso Y Mantenimiento

It is necessary to keep a safe distance when they are installed in spaces where materials are susceptible of being flammables, either the constructions
materials or different materials that surround the stove.

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 of basic importance in the proper functioning of the stove and primarily has two functions:
• Evacuate the smoke and the gas safely out of the house.
• Provide sufficient draft to the stove in order to keep the fire.
The draft also affects the intensity of the combustion and the heating performance of your equipment. A good draft of the fireplace needs a reduced
regulation of the air for the combustion, while a lack of draft 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 draft).
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.
Never use the same chimney for several equipments at the same time
It is not recommended the fit in horizontals sections. The horizontal section will not be longer than 3 meters.
It must be installed a "T" with hermetic cover at the stove exit smoke that allows the regular inspection or the heavy dust
download.
There will not be more than 4 changes of direction, including the register "T" for the cleaning.

The optimum draft 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 draft regulator.
To check if combustion is correct, control if the smoke out the chimney is
transparent. If smoke is white means the equipment is not properly regulated or
the pellet is being used has a too high humidity. Otherwise, the smoke is grey or
black means 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: fibre cement, galvanized steel and rough and
porous interior surfaces. A 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.
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.
