4. CHIMNEY

Special attention should be drawn to the chimney quality which has to be manufactured
according to standards. The maintenance of the chimney has to be regular. The stove is
connected to the chimney through the fitting via appropriate smoke pipes, in order to
provide the adequate tightness and the flow of smoke from the stove to the chimney. The
smoke pipe must not be positioned too deep in the chimney in order not to disturb the
draft in the chimney.
Airflow
To ensure adequate stove operation, the draft in the stove chimney flue should be
12±2 Pa. The lower value does not allow the proper combustion, and as the consequence
there is the deposit of carbon and excess quantity of smoke which goes out through the
grilles or the door. If the value of the airflow is too high, the combustion shall be too fast,
and as the result the heat goes out through the chimney. In case of draft greater than 15
Pa, the chimney flue must be fitted with a damper.
4.1 General characteristics
To facilitate the draught in the flue, the chimney must be rising at least one metre
above the ridge of the roof. The chimney must not be covered by surrounding objects
(Picture 4).
The dimensions of the chimney may vary on the basis of the model of flue. However, to
guarantee good disposal of the fumes, the section of the air passage at its exit must
always be twice the size of the section of the smoke pipe, and furthermore the cap of the
chimney must never obstruct the draught.
The chimney guarantees the conveyance of the fumes outwards even when there are
strong horizontal winds and stops them from being blown back down the chimney.
Bad maintenance of the chimney stops the smoke passage due to breakage or
separation of cement mortar, brick or other material used for chimney construction, as well
as due to product deposits combustion and intrusion of foreign objects.
Chimney must have sufficient heat insulation; otherwise it can lead to condensation.
The internal parts of the whole flue should have a smooth surface, and the material
used should be chemically and thermally resistant to products of combustion.
In case of any problems connected with chimney, you should consult professionals and
chimney sweepers.
