Product Description

The AO SMITH 100262938 is a 1-inch combination automatic valve (CAV) natural gas service kit designed for residential and light-commercial hot water heating applications. This kit provides the gas valve components needed to restore proper gas flow control in a water heater, making it a direct service replacement for qualified technicians. The valve is rated for natural gas service and sized at 1 inch to match standard inlet and outlet port configurations found in typical storage-tank water heaters. Licensed plumbers and HVAC technicians are the primary installers for this type of component.

This service kit is intended for hot water heater heating applications where the existing gas valve has failed or is operating outside acceptable parameters. It is suited for installations using natural gas supply and is designed to return the appliance to OEM performance standards. The N3 designation indicates a specific valve series configuration within the AO SMITH product line. Installers should confirm the inlet size and gas type match the unit being serviced before ordering.

Installation Notes

Gas valve replacement must be performed by a licensed plumber or gas technician in accordance with local codes and the applicable International Fuel Gas Code (IFGC). Shut off the gas supply at the upstream shutoff valve and allow the system to depressurize fully before beginning any disassembly. Verify that the replacement valve matches the inlet size, gas type, and BTU rating of the original before installation. Do not restore gas service until all connections have been leak-tested with an approved detection solution.
