White-Rodgers 36C84-945 Gas Valve

The White-Rodgers 36C84-945 Gas Valve is a redundant pilot gas valve engineered for precision fuel control in intermittent ignition systems. Built with a 3/4" x 3/4" NPT inlet and outlet configuration, this 24V gas valve features a fast-opening characteristic that ensures rapid ignition response for demanding HVACR heating applications. Rated for up to 280,000 BTU, the unit incorporates an integral gas pressure switch and specialized electrical terminals—including three 1/4" spade terminals and one 5/16" diameter pin terminal—to facilitate seamless integration with Cycle-Pilot and mercury flame sensor setups.

This technician-grade 36C84-945 serves as the direct 36-series replacement for the 36C84-445 and Slant/Fin 410-949-000 models. Out of the box, it is configured for natural gas but includes a dedicated LP conversion kit, providing field flexibility for liquid propane installations. The assembly comes complete with reducer bushings and a 24" lead with barrel and 1/4" connectors, allowing for efficient retrofitting without additional sourcing of mounting hardware or wiring harnesses.

• High-Capacity Performance: Optimized for systems up to 280,000 BTU, supporting a wide range of commercial and residential furnaces.
• Broad Compatibility: Replaces White-Rodgers 36C84-445 and various Slant/Fin part numbers with a modern ON-OFF switch interface.
• Field Versatility: Includes an LP kit and reducer bushings to adapt to different fuel types and pipe sizes (3/4" to 1/2") instantly.
• Redundant Safety: Dual-solenoid redundant pilot design ensures the main regulator remains closed unless the pilot is properly established.

Is the 36C84-945 a suitable replacement for standing pilot systems?
No, this model is specifically engineered for cycle pilot or intermittent ignition (IID) systems and is not compatible with standing pilot, HSI, or DSI configurations.

What are the primary differences between the 36C84-945 and the older 36C84-445?
The 36C84-945 is the current production version, replacing the older 400-series models. The primary physical update is the transition from a traditional control knob to a more durable integrated ON-OFF switch.

Does this valve support mercury flame sensor connections?
Yes, the valve body features the specific electrical connection points required for mercury flame sensor integration found in older Slant/Fin and Bryant equipment.
