In order for the stove to operate efficiently, it is necessary to supply the position in which the
stove is placed with enough airflow required for combustion. Since stoves get the airflow from the
room in which they are placed, it is highly important that these feature enough air. In cases of
sealed windows and doors (as in houses designed for saving energy) there could be a lack of fresh
airflow, which can have a negative effect on your comfort, as well as safety. Therefore it is
necessary to provide an additional air supply via an outside air suction device and place it near the
stove. Kitchen hoods with air extraction (suction) installed in the same or adjacent room to the
some causes a drop in pressure, causing the combustion gases to flow out (thick smoke, smell).
Therefore it is necessary to secure a larger fresh airflow.
3 CHIMNEY
The basic requirements for its proper functioning are:
a) circular-shaped inner cross seection is reccommended,
b) thermal isolation and impermeability are required so the materials used are to be
temperature resistant,
c) there are not to be any narrowings, it has to be laid vertically,
d) if previously used, it has to be cleaned,
e) it has to meed all the technical requirements brought in the Instructions for Installation.
If the chimney is square or rectangle-shaped, its inner edges are to be curved. Too small an
inner cross section diminishes the smoke suction capacity. Minimal hight of 4m is reccommended.
Use of asbest-cement, galvanized steel, rough or porous inner surfaces are not allowed since
they reduce its normal operation.

The chimney top is to be placed above
the house roof or at least 10° from the
top as shown in the illustration.
