Fireplace system without air grille (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).

9.7
Expansion joints
There must be no direct connection between fireplace insert and cladding (11). Therefore all points of
contact between appliance and cladding must be separated with a sealing tape (glass fibre tape).
Therefore neither must the frame (23) rest on the appliance or be screwed, bolted or welded to it.
9.8
Cladding
The room-facing cladding (11) must be made of construction material class A1 non-flammable materi-
als. These are e.g. wall tiles, wall bricks, stove tiles, metal, plaster on lathing.
9.9
Fireplace aprons
The fireplace apron must not have any direct connection to the fireplace insert. It must be set up to be
self-supporting. The manufacturer offers various frames (23) for this purpose.

Ornamental beam
The ornamental beams (24) are permissible at a distance of
at least 1 cm in front of the cladding (11) and frame (23) of
the open fireplace insert if:
• the ornamental beam is not a component of the build-
ing.
• the clearance spaces to the cladding are so open that
no accumulation of heat can occur.
• the ornamental beam is not within the radiation area of
the open fireplace insert.
