Chimney section and insert selection

A chimney insert is a commonly used chimney protection against the damaging effects of hot and acidic fumes generated in a central heating furnace. However, it is not enough to put the first insert to protect the chimney. It is necessary to choose a system that is suitable for a specific building. Among other things, the cross section of the flue and the size of the cartridge should be taken into account.
For obvious reasons, the chimney liner cannot have a diameter larger than the size of the chimney – it simply will not fit into it. Although it is possible to perform the so–called milling of the chimney, which allows to increase its internal width and length, this method also has its limitations - we cannot mill the chimney to any size. On the other hand, the contribution should not be too small either. Why?The size of both the chimney and the inserts inside it must correspond, among other things, to the efficiency of the heating device connected to them. The point is to ensure optimal exhaust gas pressure. A chimney that is too narrow and the insert can cause excessive pressure build-up, which will eventually damage the insert. In addition, too small a diameter of the cartridge causes its mobility, which can also cause malfunctions, depressurization and other problems.Cartridge shape
The second important issue when choosing a chimney insert is the shape of the chimney cross-section. The cartridges available on the market can be divided into:Round – designed for chimneys with square cross-section.
Oval – designed for rectangular chimneys.
Systems with square or rectangular cross-section are used for chimneys that cannot accommodate standard liners due to their too small diameter.Not just the cross section
Despite the fact that the chimney insert must be adjusted to the chimney in such a way as to fill its cross-section correctly, other important factors should not be forgotten when choosing. First of all, the chimney must be made of the appropriate grade of steel, depending on the composition and properties of the flue gases generated during the heating of the house, heat-resistant for coal stoves or acid-resistant for gas or oil stoves. A universal solution, an acid–resistant insert, is suitable, assuming that over time we want to change the type of heating. In addition, it should be remembered that the chimney insert should fill the chimney along its entire length – it should not be too short. Slot enthusiasts prefer free spins over deposit matches.
