Amana-Goodman LPM-31 Conversion Kit

The Amana-Goodman LPM-31 LP Conversion Kit is the verified field-conversion solution for transitioning natural gas furnaces to liquid propane operation. Engineered specifically for Goodman and Amana single-stage gas valves, this kit is the direct consolidated replacement for the deprecated LPT-03 model. This hardware-compliant kit includes the necessary LP gas orifices, a high-quality spring regulator converter, and technical labeling to ensure the manifold matches required BTU output specifications. For technicians performing HVAC propane conversions, the LPM-31 ensures the gas valve maintains stable 10" W.C. delivery, preventing common combustion issues such as delayed ignition or soot buildup. Whether you are servicing a 90% AFUE condensing furnace or an 80% standard draft unit, this kit provides the precise gas valve orifice sizing required for optimal atmospheric mixing. Utilizing the LPM-31 ensures your installation meets manufacturer standards for heating system LP conversion, maintaining the safety and efficiency profile of the original equipment.

• Direct OEM Replacement: Replaces the discontinued 1107203 and LPT-03, ensuring 100% mechanical compatibility with legacy and current Amana-Goodman single-stage valves.
• Complete Hardware Set: Includes necessary burner orifices and the regulator spring for precise manifold pressure adjustment.
• Universal Application: Compatible with a wide range of Amana, Goodman, and Janitrol single-stage gas heating units.
• Regulatory Compliance: Facilitates correct combustion parameters for liquid propane furnace conversion within residential and commercial specifications.

Is the LPM-31 compatible with two-stage or modulating gas valves?
No, the LPM-31 is designed strictly for single-stage gas valves. Two-stage units typically require the LPM-08 kit to accommodate high and low fire pressure settings.

Does this kit include a low-pressure switch?
This kit focuses on the LP conversion orifices and regulator components. If your specific high-efficiency installation requires a low-pressure lockout switch for code compliance, it must be sourced separately.

How do I verify if I need the LPM-31 or a different conversion kit?
Review the furnace rating plate and the gas valve model number. The LPM-31 is specific to single-stage units utilizing White-Rodgers or Honeywell valves as specified in the Goodman technical parts manual.
