Ao Smith 100111100 Concentric Vent Kit Vertex

Product Description

The AO SMITH 100111100 is a concentric vent kit designed for use with Vertex Series residential water heaters. Concentric venting combines the supply air intake and exhaust flue into a single, coaxial assembly, simplifying the wall or roof penetration required during installation. This configuration reduces the number of penetrations needed and is well suited to high-efficiency condensing water heater applications. The kit is a direct accessory for the Vertex product line and is typically installed by licensed plumbers or water heater service technicians during new installation or system upgrade projects.

This vent kit is intended for residential applications where the AO SMITH Vertex Series water heater is installed indoors and requires a concentric venting path to the exterior. The concentric design draws combustion air in through the outer annulus while exhausting flue gases through the inner pipe, keeping both runs within a single penetration point. This layout is common in utility rooms, mechanical closets, and finished spaces where minimizing wall penetrations is a priority.

Key Features

• Concentric coaxial design combines intake and exhaust into one wall or roof penetration
• Engineered specifically as an accessory for the Vertex Series residential water heater line
• Supports high-efficiency venting requirements of condensing water heater installations

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician in accordance with local mechanical codes and the manufacturer's installation instructions. Shut off the gas supply and power to the water heater before beginning any venting work. Verify that the vent termination location meets clearance requirements per local code before cutting any penetrations. Do not mix components from other venting systems with this kit.
