2 System Requirements

2.1 External combustion air supply

Every combustion process requires oxygen. This oxygen is extracted from the environment of the heating appli-
ance.
The exterior shell of modern buildings is very dense. As a result, insufficient fresh combustion air flows in, mak-
ing an external supply of combustion air essential. This is also important if ventilation systems are used in the
house.
NOTE!: The combustion air connection is marked on the back
of the appliance with a supply air symbol.
Some appliance types may also be connected via the floor.
To connect the appliance, a pipe or hose with a minimum diameter of 60mm must be used. If the pipe length is
more than 2m, the diameter should be at least 100mm. The maximum length of the pipe should not exceed 5m
and should have a maximum of three elbows.
If there is a direct connection to the outside wall, care must be taken to prevent condensation and to ensure that
the inlet is protected against the wind.
A lack of combustion air impairs combustion, and results in increased soot formation and ash accumulation.

2.2 Connecting to the chimney

The information contained in this manual is of a general nature.
National and European standards, local and building regulations,
and fire safety provisions must also be observed and complied
with.
The stove must be connected to a flue approved by the chimney
sweep. Care must be taken to prevent condensation from entering
the stove.
NOTE!: The flue connection is marked with an exhaust gas
symbol on the back of the appliance
The flue pipe must be connected in line with the technical data sheet. If you have any questions, please contact
your dealer.
The chimney must be laid out according to the technical data of the stove (see section: Technical Data).

The horizontal length of the flue gas pipe should not exceed 2.5 m.

A maximum number of 3 x 90° elbows should not be exceeded. Each elbow should be provided with a

cleaning aperture.
The chimney must be resistant to condensation.

The chimney must provide at least 3-12 Pa draught to ensure the flue gases are sufficiently extracted,

even in the event of a power failure.
