Chimney and ventilation ducts are installed as self-supporting structures, separately from the other elements of a building. The ducts should be made according to the specific technical documentation developed for the building and to the relevant Polish standards. When the construction of the chimney is completed it should be subject to a final acceptance procedure as required by the Polish standard.
The assembly of a three-layer chimney is very simple. It should be mounted precisely and according to the guidelines.
Precise assembly is a prerequisite for long-lasting and reliable performance of the chimney. Proper preservation makes the chimney work properly for more than 30 years.
