Ao Smith 100266133 Concentric Pipe Vent Kit 10 Inches

Product Description

The AO SMITH 100266133 is a straight concentric pipe vent kit designed for water heater venting applications. Concentric vent systems route combustion air intake and exhaust flue gases through a single termination point using a pipe-within-a-pipe configuration, simplifying roof or sidewall penetrations. This kit measures 10 inches in length and is suited for direct-vent and power-vent water heater installations. Licensed plumbers and HVAC technicians typically handle this type of venting work to ensure code-compliant termination and safe combustion air supply.

This vent kit is intended for use with direct-vent water heater systems that require concentric piping to separate intake and exhaust streams within a shared assembly. The straight configuration makes it appropriate for vertical or horizontal vent runs where a linear section is needed. It fits into residential and light commercial water heater installations where the venting system requires a properly sized straight extension segment.

Key Features

• Straight concentric pipe design routes intake and exhaust through a single assembly
• 10-inch length suitable for short straight vent run sections
• Designed for direct-vent water heater venting configurations
• Simplifies wall or roof penetrations by consolidating intake and flue into one opening

Compatibility

Designed as an OEM-style replacement vent kit for AO SMITH direct-vent water heaters requiring concentric pipe venting components.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with local mechanical codes and the appliance manufacturer's venting instructions. Always shut off the water heater and allow it to cool before disconnecting or modifying any vent components. Verify that all joints and connections are properly sealed to prevent flue gas leakage. Follow applicable codes such as the International Fuel Gas Code (IFGC) for vent termination clearances and configuration requirements.
