3.4 SPECIAL SAFETY MEASURES FOR PROTECT-
ING ADJACENT COMBUSTIBLE CONSTRUCTION
COMPONENTS FROM FIRE (WHEN RETROFITTING
THE CASSETTE INTO A FIREPLACE)
1. There must be a distance of at least 50 mm between built-in furniture
and the fireplace casing.
2. In the case of construction elements that only border small areas of the
cassette (wall, floor or ceiling coverings), it is recommended that you
maintain a distance of 10 mm.
3.5 WOODEN BEAMS
Wooden beams must not be fitted in the fireplace’s thermal radiation field.
Any wooden beams above a fireplace must be completely ventilated on all
sides by a minimum of 10 mm. Directly fixing them to thermal bridges is
not allowed.
3.6 HEAT INSULATION MATERIAL
Heat insulation materials are only required when the adjacent construction
components of the building / fireplace location etc. need to be protected
against “high” temperatures. This is the case for combustible and load-
bearing construction components. The insulation thicknesses listed are
based on the reference insulation material rock wool according to AGI-Q
132. Silicon-based insulation material can also be used with the relevant
building approvals. These materials enable a significant reduction in the
insulation thickness (e.g. Silka type: 250 KM)
3.2 THERMAL RADIATION FIELD
No combustible construction components, furniture, curtains or decoration
may be placed within a distance of 800 mm (see Fig. 4) of the firebox door
in the thermal radiation field. This distance can be reduced to 400 mm when
a ventilated radiation protection plate is installed between the fireplace and
the combustible elements. No combustible objects may be placed within a
distance of 500 mm above the fireplace.
3.3 LOAD-BEARING COMPONENTS MADE OF CON-
CRETE AND REINFORCED CONCRETE
The fireplace cassette is to be installed in such a way that no load-bearing
construction components made out of concrete or reinforced concrete are
located at the side of the outlet points for the hot air within a distance of
500 mm at the front and up to a height of 50 mm above the outlet points
for the convection air.
