    • A venting system for a direct vent fireplace or other direct vent appliance to direct combustion gases to an exterior area. The direct venting vent pipe facilitates unrestricted lengths of pipe installations. The vent pipe has a double wall construction forming an interior axial passageway and a coaxial outer passageway. The double walls are spaced apart by an insert to maintain coaxial spacing. Sections of the vent pipe are lockingly connected to prevent separation and ensure sealing connection between the pipe sections. Elastic seal members are utilized between the matingly connected sections and a mechanical lock assembly prevents separation.
    • 用于直接通风壁炉或其他直接通风设备的排气系统将燃烧气体引导到外部区域。 直通排气管促进管道安装的不受限制的长度。 排气管具有形成内部轴向通道和同轴外部通道的双壁结构。 双壁通过插入件间隔开以保持同轴间隔。 排气管的部分被锁定连接,以防止分离,并确保管段之间的密封连接。 弹性密封构件在配合连接的部分之间被利用,并且机械锁定组件防止分离。

    • A fireplace venting assembly configured to vent a heating source combustion chamber. The venting assembly includes first, second and third panels. The first panel includes a first opening formed therein. The second panel includes a second opening formed therein and is spaced apart from the first panel to define a first venting chamber that is in fluid communication with the combustion chamber. The third panel includes a vent pipe opening formed therein and is spaced apart from the second panel to define a second venting chamber that is in fluid communication with the first venting chamber. The venting assembly also includes a device that is configured to provide a vacuum force at the vent pipe opening to draw air from the combustion chamber through the first and second venting chambers and out the vent pipe opening.
    • 构造成排出加热源燃烧室的壁炉排气组件。 排气组件包括第一,第二和第三面板。 第一面板包括形成在其中的第一开口。 第二面板包括形成在其中的第二开口并且与第一面板间隔开以限定与燃烧室流体连通的第一排气室。 第三面板包括形成在其中并与第二面板间隔开的排气管开口,以限定与第一排气室流体连通的第二排气室。 排气组件还包括被配置成在排气管开口处提供真空力的装置,以从燃烧室抽出空气通过第一和第二排气室并排出排气管开口。
