A fireplace system having one or more elements that operate to reduce the energy of acoustic signals propagating through the fireplace system before they are broadcast from a firebox of the fireplace system into a room within which the fireplace system is located. In some examples, a powered exhaust evacuation system is coupled to the fireplace system and an acoustic attenuation element of the fireplace system operates to reduce the acoustic signal of the powered exhaust evacuation system as it propagates through the acoustic attenuation element.

The present invention relates to a reverse flow prevention apparatus for common exhaust flue and a combustion apparatus having same. The reverse flow prevention apparatus for common exhaust flue, which is configured to collect exhaust gas of a plurality of combustion apparatuses, discharge the collected exhaust gas through a common exhaust flue, and prevent a reverse flow of the exhaust gas from the common exhaust pipe to each of the combustion apparatuses, includes a flange coupled to an exhaust port of each of the combustion apparatuses, an opening and closing apparatus hinge-coupled to an upper part of the flange to be opened and closed by a pressure difference between a lower portion and an upper portion thereof, and a body coupled to the upper part of the flange so as to accommodate the opening and closing apparatus. In accordance with the present invention, the reverse flow prevention apparatus, which may be directly installed at the exhaust port of the combustion apparatus, is coupled to the common exhaust flue upon installation thereof so that a separate certification may not be required to reduce time and costs for a certification.

The invention provides a device for removing heat from a building, the device having: a first tubular member defining a first cavity; a second tubular member defining a second cavity, whereby said second tubular member resides within the first cavity and is coaxial to the first tubular member; and a double conic body coaxially residing in the first cavity and coaxially positioned with the second tubular member.

Also provided is a method for removing heat from a building, the method having the steps of: directing heat-containing exhaust emanating from a flue, defining a first diameter, to a passageway received by the flue, whereby the passageway defines a longitudinal axis and a periphery circumscribing the axis; forming the directed exhaust into a slipstream, wherein the slipstream generally travels along the longitudinal axis; and routing precipitation entering the passageway to the periphery.
