Ao Smith 100110774 Intellivent Gas Control Thermostat

Product Description

The AO SMITH 100110774 is a White Rodgers Intellivent gas control thermostat designed for natural gas water heater applications. It integrates the thermostat, gas valve, and ignition control into a single unit, managing pilot ignition and main burner gas flow. The 1.25 inch shank fits standard water heater connections. A built-in 100% gas shutoff activates automatically if the pilot flame fails, eliminating the risk of unburned gas accumulation. Licensed plumbers and HVAC technicians install this control as a direct service replacement on residential storage water heaters.

This gas control is rated for natural gas (NG) heating applications. It is typically installed on residential natural gas water heaters where the existing Intellivent-style control has failed or requires replacement. The 1.25 inch shank length is a standard dimension used across a broad range of AO SMITH water heater models. The integrated design reduces the number of field-replaceable components and simplifies the service call.
