摘要： The invention relates to a direct vent gas fireplace adapted for attachment to a concentric flue pipe assembly having an exhaust pipe and fresh air pipe. A top wall, rear wall, bottom wall and side walls define a combustion chamber. A gas burner is disposed in the combustion chamber. A slanted flue attachment wall is attached to and extends between the top wall and rear wall. The slanted flue attachment wall is disposed at obtuse angles relative to the top wall and rear wall. A first pipe member is orthogonally attached to the flue attachment wall and is in fluid communication with the combustion chamber for conveying combustion products from the combustion chamber. A second pipe member having a diameter larger than the first pipe member is disposed concentrically around the first pipe member. The first and second pipe members define an annular space therebetween forming an air intake duct. A combustion air duct extends between and is in fluid communication with the air intake duct and the combustion chamber for supplying combustion air to the combustion chamber. The exhaust pipe and fresh air pipe are respectively attached to the first and second pipe members and can be selectively oriented to extend away from the fireplace in a substantially vertical or horizontal direction.
摘要翻译：本发明涉及一种适用于连接到具有排气管和新鲜空气管的同心烟道管组件的直接排气燃气壁炉。顶壁，后壁，底壁和侧壁限定燃烧室。气体燃烧器设置在燃烧室中。倾斜的烟道附着壁附接到顶壁和后壁之间并在其之间延伸。倾斜的烟道附着壁相对于顶壁和后壁以钝角设置。第一管构件正交地连接到烟道附着壁并且与燃烧室流体连通，用于从燃烧室输送燃烧产物。具有比第一管构件大的直径的第二管构件围绕第一管构件同心地设置。第一和第二管构件限定了形成进气管的环形空间。燃烧空气管道在进气管道和燃烧室之间延伸并且与燃烧室流体连通，用于向燃烧室供应燃烧空气。排气管和新鲜空气管分别附接到第一和第二管构件，并且可以选择性地定向成在基本垂直或水平方向上远离壁炉延伸。
