[Effect of combustion devices on the quality of indoor air].
Combustion devices and the equipment conducting their effluent gases such as ducts and chimneys are factors which might have an unreasonable or even dangerous impact on the quality of air inside buildings. There is a danger of flue gases entering the indoor environment during the heating process (a) if the air-circulation associated with the operation of a combustion device is disturbed or even interrupted, (b) if the air stream - as far as flue gases are involved - flows under elevated pressure, and (c) if the combustion device and the flue gas conducting equipment are not leak-proof. These three cases and their influence on indoor air quality are extensively discussed. In the German Combustion Device Code from 1980 care is taken to minimize the pollutant concentrations in rooms with combustion devices by setting special requirements for the room in which the device is located, and by prescribing the standardization of the technical characteristics of chimneys and combustion devices.
