Chimney - BOREAL E4000 Serie 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.

INTERVENTION IN CASE OF EMERGENCY
If there is fire in the stove or the flue:
a. Close the loading door.
b. Close primary and secondary air intakes.
c. Put the fire out by using carbon dioxide extinguishers (CO2 powder).
d. Request for the immediate intervention of the fire-fighters.
DO NOT PUT THE FIRE OFF WITH WATER.
WARNING:
The manufacturer declines any responsibility for the malfunction of an installation not subject to the requirements of these instructions or the use of
additional products not appropriate.

4. 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 combustion chamber in order to keep the fire.
Therefore, it is essential that it is made perfectly and that it is subjected to maintenance operations in order to keep it in good condition (many of the
claims due to malfunctioning reasons refer exclusively to a bad draft). The chimney can be made of masonry or metallic pipe compound.
It is necessary to comply with the following requirements for the proper operation of the stove:
• The interior section must be perfectly 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.
• Do not use horizontal sections.
• If it has been used previously, it must be clean.
• Respect the technical data of the instructions manual.
** For the fitter
The optimum draft for the stoves vary between 12+/-2 Pa (1.0–1.4 mm water column). We recommend checking the technical information of the
product.
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, while a higher value leads to a too rapid combustion with the heat dispersion
through the flue.
Materials that are prohibited for the chimney and, therefore, damage the proper functioning of the equipment are: fibre cement, galvanized steel (at least
in the first few meters) and rough and porous interior surfaces
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.
TThe minimum diameter must be 4 dm2 (for example, 20 x 20 cm) for stoves with a diameter below 200 mm or 6.25 dm2 (for example, 25
x 25 cm) for equipments with a diameter higher than 200 mm.
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.
