The AO SMITH 100110791 is a vent pipe assembly kit designed for use in water heater venting systems. It provides the necessary piping components to route combustion exhaust safely from the appliance to the exterior of the structure. This kit is intended for installation by licensed plumbers or HVAC technicians working on residential or light commercial water heating equipment. The assembly consolidates required vent pipe components into a single kit, reducing the need to source individual parts and helping ensure a proper, code-compliant installation.
This vent pipe assembly kit is suited for water heater applications where the existing vent pipe requires replacement or repair. It is commonly installed during water heater service calls, full unit replacements, or system upgrades where the venting configuration must be restored to manufacturer specification. Installers should verify that the kit is appropriate for the specific flue size and venting type of the unit being serviced before installation.
Designed as an OEM-style replacement vent pipe assembly kit for AO SMITH water heater systems. Verify flue size, vent type, and model compatibility before installation.
Installation should be performed by a licensed plumber or HVAC technician familiar with local mechanical and fuel gas codes, including applicable IFGC requirements. Shut off gas supply and allow the appliance to cool completely before beginning any vent work. Ensure all vent connections are fully seated and secured per manufacturer guidelines and local code. Do not operate the appliance until the venting system has been fully inspected and confirmed to be free of leaks or obstructions.
