Ao Smith 100110927 Natural Gas Pilot Burner PB-5P

Product Description

The AO SMITH 100110927 is a natural gas pilot burner replacement part designed for use with the PB-5P pilot burner assembly. It includes a 20-inch wire lead for connection to the ignition control circuit. Pilot burners serve as the standing or intermittent ignition source in gas-fired water heaters and heating appliances, maintaining a flame that ignites the main burner on demand. This part is intended for installation by licensed plumbers, gas fitters, or HVAC technicians performing burner assembly service or component-level replacement.

This pilot burner is suited for residential gas appliance applications where the original PB-5P pilot assembly requires component replacement. It is a direct OEM-style replacement part for restoring proper ignition function in natural gas systems. Technicians replacing a failed pilot burner due to clogging, orifice wear, or thermocouple seat damage will find this part appropriate for that service scenario.

Key Features

• Natural gas fuel type — not compatible with propane or LP systems without conversion
• 20-inch wire lead pre-attached for direct connection to ignition control
• OEM replacement part designed for PB-5P pilot burner applications
• Component-level replacement reduces cost versus full pilot assembly swap

Compatibility

Designed as an OEM-style replacement pilot burner for natural gas appliances using the PB-5P pilot burner assembly.

Installation Notes

Installation should be performed by a licensed plumber, gas fitter, or qualified HVAC technician in accordance with local codes and the appliance manufacturer's service instructions. Shut off the gas supply and allow all components to cool completely before beginning work. Verify fuel type compatibility before installation — this part is rated for natural gas only. After installation, test for gas leaks at all connections using an approved leak-detection solution before restoring gas service and cycling the appliance.
