Carrier EF33CZ256 Gas Valve
The Carrier EF33CZ256 Gas Valve is a reliable 2-stage gas control designed specifically for liquid propane (LP) applications in high-efficiency heating systems. Operating on a standard 24V furnace control circuit, this valve features a low-fire setting of 4.8" WC and a high-fire manifold pressure of 10.5" WC, ensuring precise fuel-to-air ratios for optimal combustion. As a direct replacement for the EF33CZ256A, this OEM component is commonly found in older Carrier and Bryant Infinity furnaces, where maintaining exact pressure regulation is critical for sequence of operation and burner stability. For technicians performing a Carrier gas valve replacement, the 36E94-302 architecture provides the necessary reliability for demanding residential environments. When diagnosing furnace gas valve troubleshooting issues, ensure your manometer is calibrated to these specific LP gas valve pressure settings to prevent nuisance lockouts or poor thermal transfer.
Key Benefits for Contractors
- Precise LP Pressure Regulation: Optimized for 4.8" WC Low and 10.5" WC High settings to accommodate 2-stage heating cycles.
- OEM Compatibility: Serving as the factory-spec Carrier EF33CZ256 replacement, it ensures seamless physical fitment and electrical connector alignment.
- High-Efficiency Performance: Engineered for Carrier furnace parts, supporting the technical requirements of Infinity-series equipment.
- Robust 24V Solenoid: Designed for high duty cycles and reliable ignition sequencing under varied residential loads.
Common Questions
Can the EF33CZ256 be used for natural gas?
No, this specific model is calibrated and orifice-matched for liquid propane (LP) systems only. Using this valve with natural gas without a conversion kit (if applicable) is unsafe and will result in incorrect manifold pressure.
Is the EF33CZ256 identical to the EF33CZ256A?
Yes, these two part numbers are technically identical and can be used interchangeably in the field without modification.
What are the manifold pressure settings for this valve?
The factory-specified outlet pressure is 4.8 inches water column for low-stage operation and 10.5 inches water column for high-stage operation.
Item is Non Cancelable / Non Returnable
