<p>The method involves placing a cylindrical part i.e. connection nut, inside a tubular space by introducing the cylindrical part by an end until an interior of the cylindrical part. A tubular element i.e. tube, is allowed to present a production unit i.e. foot-warmer, for production of hot gas and a side opening (114) near the cylindrical part. The hot gas production unit is guided in the tubular element, where the production unit leaves the tubular element radially by the side opening in a direction of the cylindrical part. An independent claim is also included for a heating device.</p> |
