In this article it has been described, how a fireplace is installed in an old house that has no fireplace previously. At this case the fireplace to be installed is from Uunisepät, but the same process is with any fireplaces.

When the fireplace is ordered straight from the manufacturer, they will supply all materials needed for the fireplace installation. In this case the order consisted of three pallets of goods.

The chimney for the fireplace was built using Leca blocks. Both the inner barrel and the insulation around it are delivered in various lengths, which make the installation easy.

The background of the fireplace was built from the fireproof material in order to protect the initial wall structures of the house. Typical for the houses from 1970’s, this house was built to a concrete slab. Therefore the weight of the fireplace and the chimney were placed directly on top of the slab. This operation required the dismantling of the floor structures. It was carried out a detailed sizing and using a mechanical knife cut. With the help of building blocks the fireplace was then lifted to the same height with the room floor.

On the top of the building blocks the fireplace’s bottom plate was installed. This installation step have to be made extra cautiously: if the base plate position deviates from the horizontal position, the error multiplies easily when the fireplace rises. The same careful attitude must be obtained when starting the tile laying; the error is easy to see in the end result.

The walls of the old houses are never straight, and the move a bit followed by the heat and moisture, so there should be some space left between the firewall and the fireplace. This too gives the possibility to place the installation totally horizontal position.

One of the roof bar of the house was in chimney’s way so it needed to be cut. Luckily it was not one of the load-bearing structures, but not any risks where taken during the installation: the ends of the cut bar were re-attached.

After the fireplace structure was set, the fireplace was decorated with the chosen tiles and seamed. Installers cleaned up after seaming, so that there would be no need for the owners of the house to clean. When this couple in the evening looked at the living room, they felt that the fireplace had been there forever!
