When installing the double-walled stainless steel fireplace, you can mount the stainless steel chimney either on a socket / base on the floor (floor installation) or on the wall (wall installation) with a base support. Various base supports are available with different contact surfaces and wall spacings. For the wall installation, the base socket of the stainless steel chimney with condensate drain is screwed onto the base support. For the floor installation, the floor plate is attached directly to the foundation / ground. From the structural conditions, such as the connecting height of the connecting cable and the height of the chimney base, it is determined where the 90º tee is fastened.
