A device for safely re-directing carbon monoxide exhaust from generators includes a base, a holding mechanism, at least one support, and an exhaust tube. The base is configured to be positioned on a grounding surface. The holding mechanism is suspended at an elevated height from the base. The at least one support is connected between the base and the holding mechanism. The at least one support is configured to support the holding mechanism at the elevated height in a vertical orientation. The exhaust tube is configured to be connected to an exhaust outlet of the generator on a first end. The exhaust tube is configured to extend from the exhaust outlet of the generator vertically through the holding mechanism to a safe exhaust height above the exhaust outlet of the generator.

In a preferred embodiment, there is provided a water heater venting assembly for directing a combustion air and a flue gas between an outdoor atmosphere and a water heater, and which includes a generally hollow housing defining a combustion air aperture, a flue gas exhaust conduit disposed in the housing, and an adjustable inlet duct coupling assembly having a retention member for placement in the housing proximal to the aperture, a gasket for placement around an outer periphery of the aperture and a combustion air supply member. The retention member is for retaining the supply member in fluid sealing engagement with the gasket to effect fluid communication between the aperture and the supply member, and is sized to permit slidable movement of the supply member relative to the gasket.

A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

The modular tubular exhaust system includes a first tubular body, a second tubular body and at least one third tubular body connecting to form, a fully assembled configuration, a vertically arranged exhaust pipe. The first, the second, and the third tubular bodies each have a tubular body first end and a tubular body second end where the first ends and second ends are configured to mate with each other to form the vertically arranged exhaust pipe. The system further includes tabs that extend radially outward on opposing sides of the tubular bodies to allow a plurality of fasteners to attach tubular bodies together when arranged in the vertical configuration. The assembled configuration may vary within the spirit and scope of the disclosure, for example, in some embodiments, the system may only have a first and a second tubular section or a first, second, and a plurality of third tubular sections.

A conduit locking system includes a first cylindrical conduit having a male and female portion. The female portion includes an engagement protrusion that is radially disposed on an outer surface, and an inner surface that is configured to engage an outer surface of a male portion of a second cylindrical conduit to define a continuous fluid passageway. The conduit locking system comprises an annular band having a tensioner and is configured to engage the male portion of the second cylindrical conduit. The annular band may also comprise a plurality of fingers disposed radially about the annular band. The plurality of fingers may be configured to engage the engagement protrusion of the female portion of the first cylindrical conduit. The conduit locking system is manipulatable between an unclamped position to a clamped position.

A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

An adapter and adapter system for connecting a female end of a first chimney portion to a male end of a second chimney portion. The adapter includes a first radial adapter portion with a first inner surface and a first outer surface extending along a first axis and wherein the first inner surface and the first outer surface are substantially coaxial. The adapter further includes a first locking interface protruding outward from the first outer surface and configured to engage with a first locking interface of the first chimney portion and a second locking interface protruding inward from the first inner surface and configured to engage with a second interlocking interface of the second chimney. The first outer surface of the adapter is configured to be received within the female end of the first chimney portion and the inner surface is configured to receive the male end of the second chimney.

A device for safely re-directing carbon monoxide exhaust from generators includes a base, a holding mechanism, at least one support, and an exhaust tube. The base is configured to be positioned on a grounding surface. The holding mechanism is suspended at an elevated height from the base. The at least one support is connected between the base and the holding mechanism. The at least one support is configured to support the holding mechanism at the elevated height in a vertical orientation. The exhaust tube is configured to be connected to an exhaust outlet of the generator on a first end. The exhaust tube is configured to extend from the exhaust outlet of the generator vertically through the holding mechanism to a safe exhaust height above the exhaust outlet of the generator.

A piping connection unit of a combustion apparatus supplying and discharging air through a duct includes an apparatus-side connecting part, a connecting part and a spacer. The apparatus-side connecting part is to be connected to an air supply part or an exhaust part of the combustion apparatus. The connecting part has a diameter larger than a diameter of the apparatus-side connecting part, and communicates with the apparatus-side connecting part to be connected to a duct to be inserted from an opening part. The spacer is detachably disposed in the connecting part. The spacer is disposed between an inner wall of the connecting part and the duct to be inserted when the duct has a pipe diameter smaller than an inner diameter of the connecting part. The spacer is removed from the connecting part when the duct has a pipe diameter equivalent to the inner diameter of the connecting part.
