Lennox 56L56 Orifice

Lennox 56L56 Orifice

The Lennox 56L56 LP Orifice is a high-precision tapered orifice engineered for liquid propane (LP) conversion and gas flow regulation in residential heating systems. Also designated under the part number 56L5601, this authentic OEM Lennox replacement part is critical for technicians performing a natural gas to LP conversion on compatible furnace and unit heater models. It ensures the correct stoichiometric ratio by meting fuel into the burner assembly at the specific pressure required for propane combustion.

Constructed for durability and exact fitment, the 56L56 is frequently utilized in Lennox TUA series furnaces, including the TUA045, TUA060, and TUA075 models. As a veteran-grade HVAC replacement part, it provides the consistent manifold pressure and flame stability necessary to maintain equipment efficiency and prevent soot buildup or irregular ignition. Whether you are replacing a clogged nozzle or completing a full system changeover, using this specific gas burner orifice ensures compliance with manufacturer specifications and maintains the operational integrity of the heating unit.

Key Benefits for Contactors
  • Precise Fuel Metering: Tapered design allows for exact gas manifold pressure regulation.
  • Universal Compatibility: Fully interchangeable with Lennox part number 56L5601.
  • OEM Standards: Genuine component ensures proper threading and seating within the burner manifold.
  • System Versatility: Suitable for a wide range of Lennox residential furnaces and unit heaters.
Common Questions & Technical Support

Is the 56L56 compatible with my specific furnace model?
This orifice is a standard component for many Lennox TUA and relative unit heater series. Always verify the BTU rating and orifice drill size against your unit’s rating plate before installation.

What is the difference between 56L56 and 56L5601?
Technically, there is no difference. Both part numbers refer to the same physical LP orifice and are used interchangeably in Lennox parts catalogues.

Can this orifice be used for high-altitude adjustments?
While this is a standard LP orifice, high-altitude applications may require different sizing based on derating requirements. Consult the manufacturer's altitude adjustment tables for specific manifold pressure settings.
