The figure shows the installation situation using the Varia
1V-51-4S as an example and applies as an example for all
5. The sill beam must be located outside the area of direct radiant heat.
6 A ventilated distance of 1 cm must be guaranteed. For fastening, non-combustible holders must
be used, e.g., from metal. These must be arranged and carried out so that the fee flow of air is not
obstructed.
7. The gap between the inner edge of the combustion chamber and the sill beam has to be at least 165
cm.
5.2 CONCRETE AND REINFORCED CONCRETE
LOAD-BEARING COMPONENTS
Fireplace systems must be installed so that no load-bearing structural ele-
ments made of concrete or reinforced concrete are located within 30 cm
of the warm air exit points at the sides and up to a height of 50 cm above
the exit points.

5.3 WOODEN BEAMS

Wooden beams may not be installed within the radiation area of the fireplace insert.
Air has to circulate around with a minimum distance of 1 cm. Direct anchorage with
thermal bridges is not permitted.

5.4 INSULATING LAYERS

(See chapters 7 and 8)
Mineral wool is the insulating material normally referred to in testing insti-
tute data and current insulating material regulations. Other suitable insu-
lating materials may be used as an alternative. The materials used must be
approved by the DIBt (German Institute of Building Technology) and provided
with certificates or marking in confirmation thereof.

5.4.1 INSULATING MATERIAL THICKNESS

Details for the insulating material thickness can be found under chapter
„11. Technical details"on page 14.
The minimum insulation thicknesses there to combustible and protective
components are only valid for components with a thermal transmittance
value (U-value) > 0.4 W/m
measures must be made for fire protection (see DIN 18896:2013-12).
