摘要

The main housing (5) for the main heating group (1) contains an electric motor (2) for a blower (3) for combustion air and equipment (4) for feeding fuel and is moulded with an internal envelope (7) and the heat channel (6). There is a side part (8) which houses electrical control equipment including a resistance (10) and lighting coil (11), all enclosed by a cover (12). A pipe (15) for combustion air and another (16) for combustion products are integrally moulded in the housing together with support pieces (17), (18). The combustion tube (19) is of special steel. At each end of the assembly are entry and exit caps (22), (23). Thermal insulation can be applied as necessary. There is an exterior heat transmitting envelope (6) integrally mouled with the interior envelope.
