INSTALLATION INSTRUCTIONS
3.1. REQUIREMENTS RELATING TO THE USE OF EXISTING CHIMNEYS
The adapter material for the connection with the chimney must be made of at least
2 mm thick sheet steel and must be insulated with a heat-resistant material 3 cm in
thickness. Connect the pipes to the existing chimney using a sliding sleeve in the
ceiling (niche pipe). Check all connections for air-tightness. If the smoke outlet leads
through parts containing flammable material, such as walls, the adapter must be
encased in at least 20 cm of a mineral substance (such as aerated concrete).
Protection of the basic surface (surface)
When fitting a built-in fire on a surface containing flammable material, the surface must
be fitted with a covering layer of a non-flammable material such as concrete with a
thickness of 6 cm. The concrete plate must be of sufficient dimensions to act as a
bearing surface. The concrete plate must then be covered with at least 3 cm of heat
insulation.
Protection of the floor, in front of the built-in fire/fireplace
The floor, in front of the built-in fire/fireplace must be made of non-flammable material.
The minimum dimensions of these non-flammable surfaces must be as follows.
At the front, the dimensions are determined by the height of the heating area
measured from the bottom plate (h) plus 30 cm (h+30 cm), however no less than
50 cm.
At the sides, the dimensions are determined by the height of the heating area
measured from the bottom plate (h) plus 20 cm (h+20 cm), however no less than
30 cm.
Construction parts containing flammable substances or material and fitted
furniture within the radiation area of the fitted fireplace
Any flammable materials should be kept outside an imaginary circle with an 150 cm
radius centred on the built-in fire.
Ceiling above the built-in fire/fireplace
If the hollow space above the fire reaches as high as the ceiling, it must be protected if
it contains any flammable material and/or if it is a bearing structure. Such protection
should be in the form of a 10-cm thick heat-insulating layer.
Construction parts containing flammable substances or material and fitted
furniture outside the radiation area of the fitted fireplace
There must be a distance of at least 5 cm between the outside surfaces of the fireplace
into which the hearth is built and the construction parts of inflammable building material
and inflammable components, such as integrated furniture.
