Adjustable Water Heater Venting Assembly for Duct Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water heater venting assemblies require custom modifications due to varying dimensions and locations of inlet and outlet ducts, leading to increased installation time and costs, and lack a straightforward method for monitoring flue gas without disassembly.
Innovation Solution
A water heater venting assembly with an adjustable duct coupling system, including a hollow housing, a flue gas exhaust conduit, and a resiliently deformable gasket, allowing for fluid communication between the flue gas outlet and combustion air inlet ducts at varying distances, and enabling slidable movement for alignment and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom fabrications and modifications are made for each different water heater, then the venting assembly can accommodate varying duct dimensions and locations, but installation time and costs increase
Solution Approach 1:
The venting assembly incorporates an adjustable coupling mechanism with movable components that can be positioned at different locations and angles to match varying duct configurations on different water heaters, eliminating the need for custom fabrications and reducing installation time
Solution Approach 2:
The venting assembly is designed as a universal fit system that can accommodate multiple water heater models and duct configurations through standardized interfaces and adjustable positioning features, allowing a single assembly design to serve multiple applications without modification
2Adaptability or versatility
If custom fabrications and modifications are made for each different water heater, then the venting assembly can accommodate varying duct dimensions and locations, but installation costs increase
Solution Approach 1:
The adjustable coupling mechanism allows installers to configure the venting assembly to match different duct arrangements without requiring custom-made parts, reducing material waste and labor costs associated with custom fabrication
Solution Approach 2:
By designing a universal venting assembly that works with multiple water heater models and duct configurations, the need for expensive custom fabrications is eliminated, reducing overall installation costs while maintaining adaptability
3Difficulty of detecting and measuring
If the venting assembly is disassembled for flue gas monitoring, then monitoring can be performed, but installation time and complexity increase
Solution Approach 1:
The design allows monitoring equipment to be nested within or integrated into the venting assembly structure, enabling flue gas monitoring without requiring disassembly of the venting components

AI summary
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.
