7.7 Permissible heat insulation and primary
walling material (minimum requirements) :
1. Insulation materials: Insulation materials
according to AGI working sheet Q 132:
12.07.21.70.09 (=insulation material code
number).
This means: Insulation material group 12, Type:
stone wool,
Form of delivery group 07, Shape: Tiles,
Heat conductivity Group 21, Supply form:
G.-Curve 2
Upper application limit temperature
Group 70 corresponds to 700°C
Rated pipe density Group 9 corresponds to
90 kg/m³
2. Primary walling:
Brick tiles according to DIN 105 Part 1 and
Part 3
Bricks according to DIN 106 Part 1, DIN
4163, DIN 18151 or DIN 18152
Wall building tiles according to DIN 4166,
DIN 18162 or DIN 18163
3. Alternative primary walling and insulating
materials:
These are approved by the German Institute for
Building Technology, Berlin (DIBt). They also
mostly meet the material requirements of heat
insulation and primary walling. Details on these
building materials can be obtained from your
specialist suppliers.
8. Installation of the fireplace insert:
Once the heat insulation has been carried out
according to the insulation instructions, the
fireplace insert can be placed on the prepared
surface. Align the fireplace insert with the adjusting
screws and connected to the chimney using the
connecting piece (smoke pipe).
The chimney connection must be carried out in
keeping with DIN 18160 Part 1 and Part 2 (see
Page 5, Paragraph 7.1).
8.1 Expansion joint:
An expansion joint must be provided between
insert and covering which is closed with sealing
cord or sealing band.
8.2 Covering:
The covering of the fireplace insert on the room
side
must consist of non-combustible
materials of fire protection Class
A1 (e.g. glazed bricks, plaster on
plaster substrates, metal or ceramic
oven tile). There must be no direction
connection between
covering and fireplace
insert.
Caution! The covering of
the chimney apron must
only rest on a separate support
frame which is normally mounted to the wall.
8.3 Convection air openings:
The free non-obstrutable cross section for the air
inlet and air outlet openings must be at least 600
cm
2
each.
Caution: After the installation of the entire chimney
neither the convection air inlet nor the outlet must
be obstructed by any components whatsoever. To
avoid heat congestion, convection air inlet and
outlet openings or grilles have to be always open
during heating operation.
No
closable grilles, fins,
louvers and the like may be installed in such
openings. Convection air cross sections between
heating insert and covering as well as rear
insulation: free minimum distance between
fireplace insert and lateral covering of non-
combustible material: 50mm.
Free minimum distance between fireplace insert
and rear insulation or placement wall of non-
combustible material: 100mm.
Note: The minimum distance stated above must be
maintained over the entire height of the fireplace
insert over the entire width in each case so that the
convection air is able to flow through freely.
8.4 Convection air space:
Since the fireplace insert does not have a
prefabricated convection air chamber device a
distance to both sides of 60 mm must be taken into
account between fireplace insert and heat
insulation layer. The heat insulation layer as
radiation protection equaliser and protection
against flying fibres must be covered with a tight
sheet metal jacket of galvanized sheet metal.
The convection air openings must at least meet
the cross section mentioned above.
