Kalfire W Series, Installation And User Manual, Page: 12 / 68

Combustible materials must be shielded by insulation material
with a minimum thickness of 10 cm. The distance from the back of
the fireplace to the combustible material must be a minimum of
30 cm.
* The floor the Kalfire W tunnel is placed on must be made
of non-combustible materials. The (combustible) floor in
front of the door opening must be protected to a distance
of at least 50 cm in front of the appliance (side/sides with a
glass door).
2.4.6 Prescribed materials
Insulation
Use mats, plates or strips made from silicate insulation materials
(stone, clinkers, ceramic fibres); construction class A1 according
to DIN 4102 Part 1, with an upper limit temperature of at least
700°C, tested according to DIN 52271 and a nominal density of
80 kg/m.
These materials need to have a corresponding insulation material
registration number, according to AGI-Q 132. This number may
not include the combination “99”.
For as far as this insulation layer is not kept away from walls,
claddings or adjoining plates, attachments must be mounted at a
mutual distance of max. 33 cm.
Other insulation materials, consisting of, for example, covering
concrete or mineral base materials, must have a General
Urban Development Permit of the German Institute of Building
Technology (DIBt). For further details, see DIN 18895 resp. EN
13229/DIN 18160.
Replacement insulation materials have various heat index values,
depending on the thickness of the insulation material. The
required thickness of the insulation material can be calculated
from the graph delivered by the manufacturer.
Some heat insulation materials can be used for preconstruction
and heat insulation, in order to considerably reduce the built-in
depth. Cover heat insulating materials made from stone and
clinker fibre, so they are not subject to wear, otherwise loose
particles may be blown by the airflow into the mounting area.
Other heat insulation plates may be supplied wear proof from the
factory.
Floors
The floor, on which the fireplace is placed, must have sufficient
load bearing capacity (for the weight of the appliance, see table 5).
Combustible materials must be shielded by insulation material
with a minimum thickness of 10 cm.
* The floor the Kalfire W90/47C is placed on must be made
of non-combustible materials. The (combustible) floor in
front of the door opening must be protected to a distance
of at least 50 cm in front of the appliance (side/sides with a
glass door).
2.4.4 Installation of the Kalfire W90/47S and W90/47S
in combination with combustible materials
(e.g. a wooden wall)
When installing the Kalfire W90/47S or W90/47S pay attention to
the distance to combustible building materials:

Combustible materials must be shielded by insulation material with
a minimum thickness of 10 cm. The distance from the back of the
fireplace to the combustible material must be a minimum of 10 cm.
* The floor the 3-sided fireplace is placed on must be made
of non-combustible materials. The (combustible) floor in
front of the door opening must be protected to a distance
of at least 50 cm in front of the appliance (side/sides with a
glass door).
2.4.5 Installation of the Kalfire W80/52T and W105/47T
in combination with combustible materials
(e.g. a wooden wall)
When installing the Kalfire W80/52T and W105/47T pay attention
to the distance to combustible building materials:
