DO NOT PUT OUT THE FIRE WITH WATER.
5.2 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.
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:
(1) Stainless steel AISI 316 chimney with double insulated chamber and material resistant up to 400°C. Efficiency 100% optimum (
see
drawing D8
).
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 D9).
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.
