Clearline AKW (125mm and 150mm) and AKC (175mm and 200mm) are a stainless steel insulated chimney designed to be used with solid fuel, biomass, oil or gas and with both condensing and non-condensing boilers. It is suitable for a wide variety of different applications and is available in a polished stainless or black finish. It has a fully welded inner and outer with rockwool and ceramic fibre insulation. It is designed to withstand continuous high temperature use, can deal with condensation and is extremely resistant to corrosion.
Let us do the work: use our Flue Design Service
Safety has always been at the forefront of Clearline design. By utilising a push fit jointing system Clearline does away with the hot spots found with twist lock flue systems and its unique addition of a ceramic wool section at every joint means that it is easy to assemble and yet maintains its thermal integrity throughout its length.
Clearline AKW and AKC have been tested to have a working temperature of 600 degrees, which is 150 degrees more than most systems on the market. The 125mm and 150mm Clearline AKW can be installed within 50mm of combustible material while the 175mm and 200mm AKC have a 60mm distance to combustibles.
Clearline AKW and AKC are HETAS Approved and CE marked EN1856-1 T600
