2.4. Chimney duct
The stove must be appropriately selected to match the cross section of the combustion gas duct (ue pipe)
and the height of the ue.
The cross-sectional area of the ue and of the combustion gas duct is calculated in accordance with the follow-
ing formula:
where:
F – cross-sectional area of the ue and of the combustion gas duct [m2];
Q – rated thermal input [kW];
h – the height of the chimney [m].
In accordance with the applicable provisions of law, the ue may not be smaller than 14x14cm or its diameter
must be 15cm. Stoves with a higher thermal input require a ue with a larger cross section. The cross section
also depends on the height of the chimney.
The stove should be connected to the combustion gas duct or the vertical duct in
accordance with the applicable national standards.
The chimney draught should be as follows:
- minimum draught – 6 ± 2 Pa;
- MEDIUM, RECOMMENDED DRAUGHT – 12 ± 2 Pa;
- maximum draught – 15 ± 2 Pa.
NOTE:
To ensure the correct functioning of the stove, there must be a correct chimney
draught in the connector of the ue pipe:
▪ the stove will not function properly if the chimney draught is not sucient, resulting in excessive soot
deposits on the glass and in combustion gas ducts and reducing the total thermal power of the stove (due
to which combustion gases may escape to the room);
▪ if the draught is too strong, the burning process may be too intense, causing high consumption of fuel and
resulting in permanent damage of the stove.
The chimney should be regularly inspected by a chimney sweep company.
2.5. Connection to the chimney duct:
▪ before installing the stove, the chimney ducts and its technical parameters and condition must be inspect-
ed and approved by a chimney expert;
▪ the stove may be only installed after the ue pipe has been inspected and approved by a chimney expert.
The chimney duct must satisfy the applicable national or European standards.
The stove must be mounted and connected to the chimney in accordance with the supplied Operation and In-
stallation Manual (together with the deector plates - if they are to be used, and the insulation of the ue pipe).
The manufacturer does not recommend the assembly and installation of the appliance by the user on his or
her own. To make sure that the stove is installed and put to use in a correct and safe manner and to satisfy the
guarantee conditions, the user should have the appliance installed and put to use by a qualied installer or an
installation company. The installer is required to conrm in the guarantee card (signature and stamp) that the
stove has been installed in accordance with good building practices and the applicable legal provisions. If the
above-mentioned activities are not performed, it will invalidate the guarantee.
