ABSTRACT:
An intermediate housing that is, preferably, developed as a cast part and combines several functions and objectives in itself. The intermediate housing not only houses a driving motor for a combustion air blower and a heating air fan, but the driving motor is also disposed by means of a circumferential support developed in the intermediate housing which, at the same time, serves as a stop during the mounting. By means of an elastic bearing of the driving motor, structure-born noise transmission can be avoided. On one side, a combustion air intake connection piece, a fuel supply pipe receiving opening and an exhaust gas outlet connection piece are integrally formed. For the mounting of the heater at a mounting arrangement, the intermediate housing also has passages for fastening screws that are accessible from the direction of the top side of the heater. A receiving space, that is tightly closable by means of a cap, is provided for containing the electrical supply devices, and an ignition device and a flame detector are also housed in the receiving space. In addition, casing parts of the heater can also be fastened to the intermediate housing. At the outer surface of the intermediate housing, axially extending cooling ribs are formed that have an interrupted axial course and are circumferentially staggered with respect to one another.
