Convection air duct with convection cladding
All convection air ducts must be made of dimensionally stable, non-flammable construction materials.
The warm air pipes must be fixed firmly to the warm air-/(supply) collar of the convection cladding and
the grilles (optimally with collar plate).

• The cross-section for the air outlet (14) and the air inlet
(13) must each be at least 700 cm².
• Above at least 200 cm², air inlet and air outlet must not
be lockable.
• There must be no flammable construction materials,
e.g. wooden ceiling, and no furniture within a range of
30 cm next to and 50 cm above the air outlets (14).

Closed fireplace system (hypocaust)
The convection air circulates within the closed cladding. The heat is emitted via radiation above the
cladding.

Protecting the installation base
Installation bases (8) with flammable construction materials
with a concrete slab (7) at least 6 cm thick (dimension E),
which must be reinforced above installation bases without
adequate lateral distribution, and above that by a thermal
insulation layer (9) at least 5 cm (dimension D).
Bearing concrete- or reinforced concrete floors (8) must be
protected by a thermal insulation layer at least 5 cm thick
(9).
