ABSTRACT OF THE DISCLOSURE The invention relates to a device for evacuating into the ambient air combustion products from a condensation boiler, in which at least one downstream section of the conduit for evacuating the combustion products is coaxial to the conduit for admission of the combustion air necessary for the burner. The device comprises means for returning to the outside a fraction of the air collected in said admis- sion conduit, the downstream section of the conduit for evacuating the combustion products, the coaxial section of the admission conduit and the means for returning to the outside a fraction of the collected and define a first heat exchanger and the device further comprises means for diluting the combustion products with said fraction of collec- ted air, said dilution means being located in the vicinity of the opening for suction of the combustion air and for rejection of the combustion products into the ambient air. The invention is more particularly appli- cable to boilers with vents.
