The flooring under the fire-place
Flooring made of combustible materials like carpet, parquet floor or cork shall be protected by a
shield of non-combustible material (e.g. ceramics-, stone-, glass-floor or metal) placed under the
fire-place reaching 50 cm in front of the furnace chamber and 30 cm besides.
Joint of the chimney
WARNING:
Before connecting the fireplace to the chimney, seek advice from the competent chimney sweeper!
The connecting elements should be attached to the equipment and to each other in a properly
sealed and stable manner. They may not hang into the unobstructed cross-section of the chimney.
The interconnecting piece between the chimney and the fireplace should be of the same cross-
section size as the pipe stub of the fireplace. Horizontal connecting pieces should ascend to the
chimney in 10°. Pipes that are not heat-protected or not led vertically may not be longer than 1 m.
There should be a minimum distance of 40 cm kept between the connection pieces of the fireplace
and combustible materials in the building. Provided that the interconnecting pieces have a non-
combustible coating of minimum 2 cm, the distance from combustible materials may be at least 10
cm. If the interconnecting pieces are led through equipment or furnishing made from combustible
materials, they have to be covered with a protecting tube made from any non-combustible material
in a distance of at least 20 cm, or they have to be coated with any non-combustible material with
low heat conductance in a minimum range of 20 cm.
Smaller distances to combustible materials are permissible if it is ensured that at the rated
performance of the fireplace the temperature cannot rise over 85°C at the combustible equipment
and furnishings.
WARNING:
The connection of the fireplace to the chimney is not permissible if the effective height of the
chimney is less than 4 m, or 5 m with multiple loading (see the details of chimney calculations on
page 29).
To the chimney that the fireplace uses, a maximum of two other fireplaces, ovens may be
connected.

The fire-place can usually be
jointed
to the chimney with an arch.
When the chimney draught is weak
the
fire–place must be jointed to the
chimney through a vertical smoke tube.
