A power vent system is provided for exhausting hot combustion gas by-products. The system includes a plenum or mixing chamber, a conduit system and an air aspirating discharge assembly. Negative pressure is developed in the plenum by a blower therein; ambient air is drawn into the plenum from the atmosphere and mixed with the hot flue gases. The resulting cooled mixture is exhausted through the conduit system under pressure and, at the discharge assembly, additional ambient air is mixed with the mixture by a discharge assembly venturi effect which also accelerates the gases away from the discharge assembly.
