Planning and Instructions
Härmä Air’s ready-made chimneys are system chimneys conforming to the Ministry of Environment Decree and national regulations, CE marked according to the standards EN 1856-1 and EN1856-2. The products have been tested for Nordic circumstances and for inlets of high roof ceiling joist insulations, wall inlets and encased structure.
Mounted overlapping joints of the modules have been tested to be installed within construction insulation.
Layout images of the design
Layout images refer to situations where a chimney is led through the heat insulations of buildings. The images have been made to be indicative and to facilitate the design work.
You’ll find more specific information about the installation methods and safety distances of a chimney in the installation instructions. There are also essential details such as a sectional view of the chimney, general principal images of inlets and the installation protocol included in the installation instructions. Installation instructions should always be attached to the instruction library of a building.
