Lennox 21Z23 Kit
When you are handling a conversion on a multi-stage Lennox unit, the Lennox 21Z23 conversion kit is the standard for transitioning from natural gas to LP (liquid propane). This 2-stage gas conversion kit is engineered specifically for compatibility with Lennox furnace models in the LG/LD 024-074S/H/U, KG 024-090, and ZG 036-074 series. As a veteran tech knows, managing manifold pressure on a two-stage gas valve requires precision; this kit includes the necessary LP orifices and high/low fire springs to ensure the regulator maintains the correct 10.5" w.c. to 11.0" w.c. output for propane. By utilizing OEM Lennox 21Z23 components, you preserve the combustion efficiency of the Honeywell or White Rodgers 2-stage valves. The package includes 7 orifices, a dual-spring kit for the regulator, and the critical J/P19 jumper harness required for proper two-stage HVAC conversion. This is a field-installed solution designed for heavy-duty commercial and residential applications where natural gas is unavailable.
Key Benefits for Technicians:- Precise Fuel Transition: Includes specific burner orifices sized for the higher BTU density of liquid propane.
- Complete Stage Control: Provides both high-fire and low-fire regulator springs for accurate two-stage modulation.
- Hardware Included: Comes with the J/P19 jumper harness and detailed conversion plates for system labeling.
- OEM Standards: Manufactured as an authentic Lennox 614839-06 assembly to meet factory specifications and safety ratings.
- What furnaces are compatible with the 21Z23 kit? This kit is used exclusively for 2-stage medium and high-capacity units (identified by H, U, Q, or X in the model string), specifically LG/LD, KG, and ZG series.
- Does this include the jumper harness? Yes, the Lennox 21Z23 includes the J/P19 harness which is required for the burner box configuration on these specific models.
- Can I use this for single-stage conversion? No, this is a two-stage LP conversion kit. Using it on a single-stage valve will lead to incorrect manifold pressure and potential lockouts.
