Ao Smith 100109298 Fv Pilot Assembly Propane

Product Description

The AO SMITH 100109298 is a flammable vapor (FV) pilot assembly designed for propane (LP) water heaters and heating appliances. The pilot assembly provides the ignition source for the main burner, generating a standing flame that holds open the gas valve thermocouple circuit during normal operation. This assembly is rated for propane fuel and is engineered for use in systems with a 200 degrees F temperature rating. Licensed plumbers and gas service technicians handle installation and replacement of this component during routine maintenance or burner system service.

This FV pilot assembly is suited for residential and light commercial propane-fueled heating applications. It is designed for use in water heaters and heating equipment that incorporate flammable vapor ignition resistance (FVIR) technology. The assembly is installed in systems requiring a reliable pilot ignition source and thermocouple interface. Technicians typically encounter this component during burner tray service, thermocouple replacement calls, or full pilot assembly failures in propane-fired equipment.

Installation Notes

Installation should be performed by a licensed plumber or qualified gas service technician in accordance with local codes and the appliance manufacturer's service instructions. Shut off the gas supply and allow the appliance to cool completely before disassembling the burner compartment. Verify the replacement assembly is configured for propane service before installation, as LP and natural gas pilot assemblies are not interchangeable. Confirm all gas connections are leak-free using an approved leak detection solution before returning the appliance to service.
