- 31 - ABSTRACT OF THE DISCLOSURE The invention describes a heating device for gaseous fuels, in parti- cular liquefied gas, comprising an outer shell (2) of a U-shaped or C-shaped cross-section, the longitudinal axis of which is oriented perpendicularly to a sup- porting surface of a floor plate (4) and resting with one of its faces (17) against the latter. Furthermore, it has an inner shell (3) having a further U-shaped or C- shaped cross-section. The outer shell (2) is arranged from the inner shell (3) at a distance forming an intermediate space (28) in a direction perpendicular to a base (20) or respectively a shank (21) of the inner shell (3). The outer and the inner shell (2,3) are connected to each other by means of a connection device, in parti- cular a weld or are fused with one another, at least in the region of their longitudinal front edges of the shanks (21, 40). The inner shell (3) comprises a combustion chamber (9), which can be closed in a front region opposite the base (20) of the inner shell (3) by a door arrangement (6). The combustion chamber (9) is bordered by a covering plate (5) located on the opposite side of the floor plate (4). A gas burner assembly (13) is arranged on a burner base plate (12) secured to the inner shell (3). In the shanks (21) of the inner shell (3), in particu- lar between the longitudinal front edges (25) and a separating profile (55), admission openings (27) are arranged between the combustion chamber (9) and the intermediate space (28) surrounded by the inner and outer shell (3, 2). This space forms a flue gas passage between the admission openings (27) and the flue outlet (44), which, in the region of the covering sheet metal (36) is connected - 32 - with a flue outlet (44) by means of a smoke pipe connection piece (45). Up- stream of the outer shell (2) in the region of the two shanks (40), sheetings (19) are arranged which form a convection channel (63).
