Description of the system
Chimney system CIKO® 3V UNIVERSAL is designated for all kinds of fiuels and for all kinds of appliances with natural exhaust of flue gases. Systém consists of refractory flue liner, heat insulation and ceramic breeze block of external cladding.
Internal refractory flue liners together with refractory material that is part of the system create a solid chimney vent resisting high temperatures and changes in moisture. Internal diameters of liners are supplied in four sizes – 140mm, 160mm, 180mm and 200mm.
Foundation of chimney: chimney is founded on supporting base by setting chimney footing evenly with the level of future floor.
Condensation drain and air grate is set in chimney footing and then the chimney body can be walled.
Outlet of condensate as well as air distribution to all ventilation air holes is solved inside the foundation footing. It is necessary to lay foundation footing carefully horizontally on level surface.
Heat insulation, placed between internal refractory piece and external supporting chimney cladding has two essential functions. Primary function is to insulate internal refractory piece from external impacts and ensure the fastest possible reaction to heating-up and natural constant draught of the chimney, the secondary function is dilatation of internal piece, which, depending on temperature of flue gases shows changes in volume. Contrary from chimney cladding that retains constant volume. Actual insulation is made from two semicircular segments that are provided with lock-joint and fit closely into one another.
Chimney cladding is made from ceramic breeze blocks that are walled with supplied mortar. Breeze blocks are laid in pairs in every layer and they are turned by 90° in individual layers. Special connecting breeze blocks are used with multi-vent chimneys in every second layer. They will secure the bond of chimney wall cladding and enable to make any number of vents in any combination of diameters of internal liners.
The exhaust of chimney is important for reliable function of the chimney. This is a characteristic feature of Ciko chimneys.
Walling of the chimney body
First it is necessary to install refractory chimney flue liner. All chimney liners are installed in a way that internal groove leads down. After that, we can install heat insulation that, thanks to lock-joint in individual segments, holds exactly the desired shape and no thermal bridges are created. In the end, we will mason in ceramic breeze blocks. During laying of breeze blocks, we must make sure that mortar is evenly spread on the whole edge surface of the breeze block and that it does not fall over and clog air holes of breeze blocks. In order to ensure the correct function of chimney ventilation, all air holes (holes between insulation and chimney casing) must be clear all throughout the chimney body.
