Combustion air supply from outside the room
The combustion air that comes from outside is
connected directly to the fireplace.
The air supply from the room enters the fireplace
from underneath the surround. The Ø360 mm
connection openings at the bottom of the sides/rear
wall must be opened so that the air in the room can
flow into the convection mantle. No flexible
connectors are connected at the bottom.
The heated convection air in the room returns to the
room via the flexible connectors which are connected
at the top. The combustion air supply is completely
separated from the convection air.

Combustion air supply from inside the room
Combustion air taken from the room is best
compensated by an air inlet in the vicinity of the
fireplace. This inlet should be at least 360 cm². The
throughput coefficient must be taken into account if a
grate is used.
E.g. If the coeff. is 0.6, then the grate should be at least
600 cm².
Connecting the combustion air to the fireplace can be
effected using two Ø150 mm flexible connectors.
If the air supply cannot be taken from close to fireplace,
the air supply must be drawn via ventilation grates
installed elsewhere (e.g. through an upper window or the
wall facade).
Ensure that a closable air vent is used, so that cold air
does not flow into the room when the fireplace is not in
use.
The air supply from the room to the convection mantle is
connected underneath via flexible connectors. The
heated convection air in the room returns to the room
via the flexible connectors which are connected at the
top.
The supply of room air also takes care of the ventilation
of the installation space.
