    • An exhaust vent adapter is provided for use in a heating system having a plurality of heating units, which allows all heating units to discharge combustion gases through a single exhaust opening. The adapter comprises a body with a plurality of discrete chambers formed therein, each chamber communicating with a separate heating unit. The body of the adapter has a single exhaust opening formed therein, through which each chamber is independently connected to a separate exhaust vent pipe. The vent pipes leading from plurality of the chambers are concentrically arranged, and may be extended through a single opening in either the wall or ceiling of a building in which the heating units are installed. In a preferred embodiment, the body of the adapter has a single divider secured therein, which defines two chambers and segregates the combustion gases from a pair of heating units.
    • 提供排气适配器用于具有多个加热单元的加热系统,其允许所有加热单元通过单个排气口排放燃烧气体。 适配器包括其中形成有多个分立室的主体,每个室与单独的加热单元连通。 适配器的主体具有形成在其中的单个排气口,每个室独立地连接到单独的排气管。 从多个室引出的排气管同心地布置,并且可以延伸穿过其中安装加热单元的建筑物的墙壁或天花板中的单个开口。 在优选实施例中,适配器的主体具有固定在其中的单个分隔件,其限定两个室并且将一些加热单元的燃烧气体隔离开。

    • A collective air intake and exhaust chimney suitable for outdoor installation which avoids clogging by snow or frost, which comprises an inner flue (8), a heat insulating layer (12), an outer flue (13), an intake passage (10) between the outer flue and the heat insulating layer, and an exhaust passage inside the inner flue. The device has a double flue branch (3) suitable for connection, e.g., to each floor of a building, which is preferably similar in size and structure to the double flue (8, 12, 13) of the intake and exhaust chimney, and is adapted to be slidably fitted to the intake and exhaust pipe of a forced draft direct vent type heater, and is supported by a supporting member.
    • 一种适合室外安装的集体进气和排气烟囱,其避免雪或霜冻堵塞,其包括内部烟道(8),隔热层(12),外部烟道(13),进气通道(10) 外烟道和绝热层,以及内烟道内的排气通道。 该装置具有适于连接的双烟道分支(3),例如建筑物的每个楼层,其大小和结构优选与进气和排气烟囱的双烟道(8,12,13)相似,以及 适于可滑动地装配到强制通风式加热器的进排气管,并由支撑构件支撑。

    • The adjustable pipe fitting of the invention has double walls in accordance with Type B standards established by the American National Standards Institute and Underwriters Laboratories. In the preferred embodiment, the invention comprises a main conduit having three sections which are rotatably coupled together. A branch conduit is securely connected to the main conduit so that fluid communication exists between the branch and main conduits. The branch conduit also comprises three sections which are rotatably coupled together. The main conduit sections and the branch sections are coupled together at oblique angles relative to their respective longitudinal axes to provide a means for adjusting the fitting to accommodate connector pipes having various angles and orientations.
    • 根据美国国家标准协会和美国保险商实验室制定的B类标准,本发明的可调式管接头具有双层壁。 在优选实施例中,本发明包括具有可旋转地联接在一起的三个部分的主导管。 分支管道牢固地连接到主管道,使得在分支和主管道之间存在流体连通。 分支导管还包括可旋转地联接在一起的三个部分。 主导管部分和分支部分以相对于它们各自的纵向轴线的倾斜角度联接在一起,以提供用于调节配件以容纳具有各种角度和取向的连接管道的装置。
