Rheem Natural Gas Pilot Assembly.

Rheem AP14317P OEM Pilot Assembly – Ignition Component for Natural Gas Water Heaters

The Rheem AP14317P is a factory-specified pilot assembly designed for use in natural gas-fired residential and light commercial water heaters. This component includes the pilot burner, pilot tubing, thermocouple, and integral mounting bracket where applicable, configured for specific Rheem models using standing pilot ignition systems.

Application & Function

As part of the ignition system, the pilot assembly provides a stable flame to ignite the main burner gas supply during normal operation. The thermocouple generates a millivolt signal to the gas control valve, allowing the system to operate safely by confirming flame presence before main burner activation. Designed for compatibility with designated Rheem models, the AP14317P restores OEM performance in systems requiring pilot system replacement due to flame instability, worn thermocouple signals, or mechanical damage.

Installation Notes

This assembly is intended for field service replacement and must be installed in accordance with local code and manufacturer specifications. Ensure proper pilot flame positioning, verify orifice cleanliness, and conduct leak testing after installation. Use only with units originally equipped with standing pilot ignition systems; not compatible with DSI or hot surface ignition designs.

For safety and functional reliability, installation should be performed by a qualified technician or licensed plumbing/HVAC professional. Improper installation may result in ignition failure, gas leakage, or unsafe operating conditions.

Use Case for Professionals

Ideal for service contractors performing routine water heater maintenance or repair. The AP14317P enables quick replacement of worn or non-functioning pilot assemblies and maintains OEM ignition safety and system response characteristics. Suitable for scheduled preventative maintenance or troubleshooting pilot-dependent ignition faults in field-deployed Rheem equipment.
