Abstract
A fireplace has a manifold positioned between a combustion chamber and a flue. The manifold has a pair of inlets to supply dilution air to the flue, one extending from a front face of the fireplace, and the other from a rearward location. A baffle extends across the outlet of the manifold to prevent direct communication between the combustion chamber and flue. The inlet at the front face enables the flow of dilution air to be checked with the fireplace installed without having to accomodate the full flow of dilution air. The baffle prevents downdrafts from adversely affecting the combustion in the combustion chamber.
Claims55
A fireplace having a housing including a combustion chamber having a front face to be directed into a room, a base, a top spaced from said base, a pair of side walls extending between said top and said base at opposite edges thereof and a rear wall extending between said side walls and said top and base at a location spaced from said front face, an exhaust duct extending from said combustion chamber at a location adjacent to the intersection of said top and rear wall to allow egress of combustion products from said combustion chamber and terminating at a manifold positioned outside said combustion chamber and operable to connect said chamber to a flue, said manifold having an exhaust outlet to direct combustion products into said flue, a baffle extending across said exhaust outlet and spaced form both said outlet and said exhaust duct to prevent direct passage of combustion products from said exhaust duct to said flue, said manifold further including a pair of inlets to supply dilution air to said flue, one of said inlets being connected to an aperture provided in said front face to receive dilution air therefrom and the other of said inlets receiving balance air from a location remote from said front face.
A fireplace according to claim 12 wherein said inlet includes an inlet duct extending from a front edge of said top panel to said aperture. rear panel, said other inlet being located between a lower edge of said rear panel and said rear wall.
A fireplace according to claim 23 wherein said second portion of said inlet duct is secured to said first portion by relative sliding motion therebetween.
A fireplace having a housing including a combustion chamber with a front face to be directed into a room, an exhaust duct extending from said combustion chamber at a location remote from said front face to allow egress of combustion products from said combustion chamber and terminating at a manifold positioned outside said combustion chamber and operable to connect said chamber to a flue, said manifold having an exhaust outlet to direct combustion products into said flue, a baffle extending across said exhaust outlet and spaced from both said outlet and said exhaust duct to prevent direct passage of combustion products from said exhaust duct to said flue, said baffle including a pair of oppositely inclined surfaces converging toward an apex directed toward said flue, said manifold further including a pair of inlets to supply dilution air to said flue, one of said inlets being connected by an inlet duct extending along said housing to an aperture provided in said front face to receive dilution air therefrom and the other of inlets receiving balance air from a location remote from said front face.
A fireplace installation comprising a firebox having a front opening and a chimney spaced rearwardly of said opening and a fireplace insert located within said firebox and having a housing including a combustion chamber with a front face to be directed into a room and overlapping said front opening, an exhaust duct extending from said combustion chamber at a location remote from said front face to allow egress of combustion products from said combustion chamber and terminating at a manifold positioned outside said combustion chamber and operable to connect said chamber to a flue connection to said chimney, said manifold having an exhaust outlet to direct combustion products into said flue, a baffle extending across said exhaust outlet and spaced from both said outlet and said exhaust duct to prevent direct passage of combustion products from said exhaust duct to said flue, said manifold further including a pair of inlets to supply dilution air to said flue, one of said inlets being connected to an aperture provided in said front face to receive dilution air therefrom and the other of said inlets receiving balance air from a location remote from said front face and within said firebox.
