The Carrier EF39ZW023 LP Conversion Kit is a field-installed requirement for transitioning specific Carrier, Bryant, and Payne gas furnaces from natural gas to liquid propane. This furnace LP conversion kit includes precision-engineered main burner orifices and a Honeywell or White-Rodgers gas valve spring specifically calibrated for higher manifold pressures. As a technician, you know the importance of a gas furnace manifold pressure adjustment; this kit ensures the equipment maintains its AFUE rating and combustion stability after the fuel change. Designed for condensing and non-condensing gas furnaces, the components are machined to strict tolerances to prevent carbon monoxide issues and sooting caused by incorrect fuel-to-air ratios. Using an OEM Carrier conversion kit ensures the furnace operates within its BTU input rating while maintaining the integrity of the heat exchanger. This is a critical HVAC service part for residential installations where natural gas utility lines are unavailable.

Item is Non Cancelable / Non Returnable

• Ensures accurate LP gas manifold pressure for safe furnace operation.
• Includes factory-spec burner orifices to prevent over-firing or under-firing.
• Compatible with a wide range of Carrier 58-series and Bryant 900-series gas furnaces.
• Maintains OEM structural integrity and combustion safety parameters.
• Simplifies the gas valve conversion process during initial installation or retrofitting.

Is a manometer required for this installation?
Yes, a calibrated U-tube or digital manometer is essential to set the manifold pressure to the specific 10-inch or 11-inch W.C. requirements listed in the kit's rating plate update.

Does this kit work with all gas valves?
The Carrier EF39ZW023 is specifically engineered for use with the gas valves found in Carrier-family products. Always verify the valve brand and model number before installation.

Why is it necessary to change the burner orifices?
Liquid propane has a higher BTU density than natural gas. Using natural gas orifices with LP will lead to an extremely dangerous over-fired condition and potential heat exchanger failure.
