Lennox 11K49 Conversion Kit

Lennox 11K49 Conversion Kit

The Lennox 11K49 is a critical LP gas conversion kit designed for field technicians performing fuel conversions on Lennox high-efficiency heating systems. This OEM Lennox replacement part provides the necessary hardware to safely transition an appliance from natural gas to liquid propane, ensuring the manifold pressure and burner orifices are correctly calibrated for LP combustion characteristics. Using this Lennox furnace conversion kit maintains the integrity of the heat exchanger and burner assembly by providing the precise LP gas manifold pressure required for high-altitude or standard residential applications. As an authentic Lennox HVAC component, the 11K49 eliminates the risks associated with universal kits, such as improper thread seating or mismatched orifice sizing (DMS). For contractors, this kit simplifies the setup of G32, G40, G41, and other compatible furnace series, ensuring clean combustion and preventing soot buildup or carbon monoxide issues often found with incorrect gas delivery setups.

Key Benefits:

  • Precision Orifice Machining: Ensures exact BTU output and flame stability when switching to liquid propane (LP) gas.
  • System Integrity: Meets original manufacturer specifications for Lennox 11K49 gas valve spring conversion and manifold adjustments.
  • Streamlined Installation: Includes the necessary regulator springs and burner orifices to reduce field labor time during LP gas conversion.
  • Operational Safety: Prevents over-firing and thermal stress on the heat exchanger by maintaining correct gas flow rates.

Common Questions:

What is included in the Lennox 11K49 kit?
The kit typically includes the specific gas valve conversion spring, burner orifices designed for LP density, and the required identification labels to signify the unit has been field-converted.

Can I use this kit for high-altitude LP installations?
The 11K49 is designed for standard LP conversion. For high-altitude applications, technicians must verify the specific derate requirements and may need additional orifice adjustments based on the local elevation and Lennox technical manuals.

Is this kit compatible with all Lennox furnaces?
While it covers a wide range of G-series and modern units, always verify the Lennox 11K49 part number against the specific model and serial number of the air handler or furnace to ensure compatibility with the installed gas valve.
