CHIMNEY

The chimney is of basic importance in the proper functioning of the oven and primarily has two functions:
- Evacuate the smoke and the gas safely out of the house.
- Provide sufficient draught to the oven 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 conditions.
(Many of the claims due to malfunctioning reasons refer exclusively to a bad draught).
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 oven:
• 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 draught for the ovens varies 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 oven, 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. Drawing D11 shows some examples of solution.
