Rheem-Ruud 60-101921-81 Gas Valve

The Rheem-Ruud 60-101921-81 is a high-performance 2-stage natural gas valve designed for high-efficiency HVAC systems utilizing Hot Surface Ignition (HSI) or Direct Spark Ignition (DSI). Engineering for slow opening operation, this ProTech 36G series valve ensures a smooth and quiet ignition sequence, minimizing the mechanical stress often associated with fast-acting alternatives. As an OEM replacement for models 60-101921-01 and 60-23490-12, it maintains a 140,000 BTU/HR capacity and features 1/2" NPT inlet and outlet ports. For field technicians, the inclusion of built-in pressure taps and 1/4" quick-connect terminals facilitates rapid manifold pressure adjustments and straightforward wiring. This redundant valve provides precise fuel regulation in both low-fire and high-fire stages, ensuring compatibility with Rheem/Ruud furnace models including the UGLQ, RGRK, and RGRL series. Its robust construction protects against inlet debris with integrated screening, making it a reliable choice for critical heating repairs.

Key Benefits

• OEM Precision: Direct replacement for obsolete part numbers 60-101921-01 and 60-23490-12, ensuring a perfect physical and electrical fit.
• Optimized Ignition: The slow opening gas valve design reduces acoustic noise and prevents flame rollout during initial startup.
• Two-Stage Efficiency: Specifically engineered for 2-stage natural gas furnace units to provide tiered heating and improved fuel economy.
• Service Friendly: Equipped with dual pressure taps for easy verification of high and low fire manifold settings.
• Debris Protection: Features internal inlet and outlet screens to prevent contaminants from fouling the internal valve seat.

Common Questions

While this unit is a natural gas valve, it can be converted with the appropriate 60-21193-06 LP spring kit. Always verify furnace nameplate requirements and adjust manifold pressure according to the manufacturer's manifold specifications.

Ensure the 24V signal is reaching the 60-101921-81 solenoid. If the valve fails to open despite receiving power, check for blockages or use the pressure taps to verify if gas is being delivered to the manifold. Resistance checks on the coils can also identify electrical failure within the redundant solenoids.

No, this is a 36G sequence valve designed for HSI/DSI intermittent ignition systems. It does not have a pilot output and cannot be used in systems requiring a continuous standing pilot.
