This concentric vent kit is suited for residential and light commercial water heater applications where a single wall penetration is required for both combustion air supply and flue gas exhaust. The 48-inch length accommodates standard venting runs in typical utility room or mechanical closet installations. It is intended for use as an accessory with compatible AO SMITH water heater models that support concentric venting configurations.
Designed as an OEM-style accessory replacement for AO SMITH water heater models that support concentric vent configurations. No specific compatible model numbers were provided in available product data.
Installation should be performed by a licensed plumber or HVAC technician familiar with local mechanical codes and manufacturer venting requirements. Always shut off the water heater and allow it to cool before disconnecting any existing vent components. Ensure all joints and connections are properly sealed per the manufacturer instructions and applicable local codes.
