<p>The hearth (1) has a combustion chamber (4) comprising an opened door, and a chimney connection (6) supplying heating gas from the combustion chamber through the chimney connection to a chimney. A heating gas chamber (5) is arranged along flow direction of the heating gas between a filter element i.e. upper rear plate (4e), at an upper rearward region of the combustion chamber and the chimney connection. The filter element passes a part of the heating gas. A catalytic element effective to the heating gas is arranged in the heating gas chamber in a flow path of the heating gas.</p> |
