White-Rodgers G01A-512 Generator

The White-Rodgers G01A-512 is a professional-grade 750 millivolt power generator designed for high-performance self-generation control systems. As a veteran-preferred thermopile replacement, this unit provides the necessary DC voltage to operate millivolt gas valves and relays without an external power source. It features 36-inch fiberglass leads terminating in standard F spade terminals, ensuring a secure electrical connection even in high-heat environments. This PG9 series generator is specifically engineered for compatibility with E31-12 pilot burners and other similar screw-in type pilot assemblies. The inclusion of a PG9 adapter and universal mounting clip allows for versatile field installation and reliable pilot generator service. Built with a high-temperature stainless steel cover, it ensures maximum flame stability and long-term durability for demanding HVAC gas heat controls.

• Universal Compatibility: Includes a PG9 adapter and clip for seamless replacement of common screw-in millivolt generators.
• High-Heat Resilience: Features 36-inch leads with fiberglass insulation to prevent wire degradation near the combustion chamber.
• Reliable Output: Consistently delivers 750mV to ensure millivolt-actuated gas valves open and close reliably.
• Easy Installation: Designed with F spade terminals for quick "plug-and-play" connection to the gas control block.

Is the White-Rodgers G01A-512 compatible with my fireplace?
If your system utilizes a 750 millivolt self-powering gas valve and a screw-in style thermopile, this unit is a direct replacement, especially for E31-12 series burners.

What is the difference between a thermocouple and this 750mV generator?
While a thermocouple typically generates 25-30mV to hold a safety magnet, the G01A-512 is a thermopile generator producing 750mV, which is powerful enough to operate the entire gas valve circuit.

Do I need to replace the adapter sleeve when installing this?
This model includes the required PG9 adapter, so you can replace both the generator and the mounting hardware simultaneously for a clean fit.
