Abstract (en)

[origin: EP0643273A1] The invention starts out from a combustion gas-producing installation, especially a hot water heating installation, having a suction fan (12) for the combustion gases and having one or more downstream heat exchangers (11, 14). In order to improve the safety of these installations and avoid the possibility of combustion gases causing damage, according to the invention the combustion chamber is assigned a vacuum gauge and, in addition, the suction fan (12) is arranged after the last heat exchanger (11, 14), seen in the flow direction of the combustion gases. <IMAGE>
