1)
Mounting wall: When the mounting wall is comprised of combustible materials, then these must be
protected by means of the fire protection measures specified above.
2)
Brick lining: When the components are made of mineral, non-combustible building materials (e.g. aerated
concrete) located in front of walls to be protected, then these must at least have a thickness of 10 cm.
Mounting walls are considered as brick lining when they are at least 10 cm thick and are not made of
combustible materials.
3)
Reference insulation material: In regard to the specification of the insulation layer thicknesses and the
insulation layer construction within these guidelines, the thickness of the stone or slag fibre in accordance
with DIN EN 14303 with a heat conductivity of 0.04 W/mK is generally viewed as a reference size. When
using substitute insulation material, a conversion must be calculated in accordance with this reference size to
the required layer thickness. Please refer to the respective officially recognised suitability certificates for the
corresponding calculation procedures, tables or diagrams.
4)
Flue pipe/connection piece: When the chimney flue is routed through a combustible wall, then this must be
insulated sufficiently, ensuring that no temperatures can occur that exceed a value of 85 °C.
5)
Ceramic storage mass
6)
Heating chamber ceiling: The heating chamber ceiling CAN, BUT DOES NOT HAVE TO BE insulated. However,
when the covering is attached upwards to the ceiling, then insulation is required. The heat insulation can
either be performed with the reference insulation material or a substitute insulation material. In the event of
a non-insulated heating chamber ceiling, the distance between the upper edge of the firebox and the heating
chamber ceiling must be at least 10 cm.
7)
Covering
8)
BIS bricks: For the insulation of the KMS to the floor in order to prevent heat conduction into the floor.
9)
Base for the KMS pulley system: This must be stable and may not be comprised of absorbent materials (no
Isoboard!)
10)
Insulation of the floor: In the event that the installation surface is stable, however made of combustible
components, then floor insulation must be created. This can be performed with the use of a reference or
substitute insulation material. In the event of the use of Ortner Isoboard, this corresponds to a layer
thickness of 6 cm.
11)
Stable base for load distribution: When the installation surface has insufficient stability, then this must be
compensated with a reinforced concrete slab. Then the concrete slab must be insulated with a reference or
substitute insulation material (e.g. 6 cm Ortner Isoboard).
12)
Substitute insulation material: (e.g. made of vermiculite, calcium silicate, expanded clay or other mineral
building materials). Can be used as a substitute for the brick reference insulation material. This must
have a general planning approval of the
Deutsches Institut für Bautechnik
(DIBt) (German Centre of
Competence for Construction) as a usability certificate (applies to Germany). Please refer to the general
planning approval for the layer thickness of the substitute insulation material.
13)
Back ventilation: If required
