The AO SMITH 100112163 is a PVC concentric termination kit designed for direct-vent water heater and boiler venting systems. Concentric venting routes combustion air intake and exhaust flue gas through a single penetration point, simplifying wall or roof terminations and reducing the number of exterior openings required. This kit is ULC listed, meeting Canadian safety certification standards for venting components. It is typically installed by licensed plumbers, HVAC technicians, or gas fitters working on residential or light commercial water heating equipment that uses PVC vent pipe.
This termination kit is suited for condensing water heaters and boilers that require a concentric vent termination at the exterior wall or roof. The concentric design keeps intake and exhaust in a single assembly, making it a practical solution for installations where space at the termination point is limited or where minimizing exterior penetrations is a priority. Installers working on ULC-compliant systems in Canada will find this kit meets the relevant certification requirements for the application.
Designed as an OEM-style replacement concentric vent termination kit for AO SMITH condensing water heaters and boilers equipped with PVC venting systems requiring ULC listed components.
Installation should be performed by a licensed plumber, HVAC technician, or gas fitter in accordance with local codes and the appliance manufacturer instructions. Shut off the water heater or boiler and allow the unit to cool completely before disconnecting any venting components. Follow all applicable venting clearance requirements for exterior terminations as specified by local authority having jurisdiction. Do not use this kit with non-PVC or non-concentric vent configurations it was not designed to serve.
