Thermal Radiation Field; Load-Bearing Components Made Of Concrete And Reinforced Concrete; Special Safety Measures For Protecting Adjacent Combustible Construction Components From Fire (When Retrofitting The Cassette Into A Fireplace) - Spartherm XS 500 Installation And Operating Instructions Manual

No combustible construction components, furniture, curtains or decoration
may be placed within a distance of 800 mm (see Fig. 3) 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
fireplace.
2.10 Load-bearing components made of 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
