Lennox 54M90 Orifice
The Lennox 54M90 LP Orifice is a critical metering component designed for precise gas-to-propane conversion in compatible Lennox heating units. Engineered for durability and high-tolerance performance, this 0.034-inch orifice ensures steady pressure regulation and fuel flow, preventing common combustion issues such as soot buildup or irregular flame patterns. For contractors performing a Lennox furnace LP conversion, using OEM-spec orifices is essential to maintain the integrity of the heat exchanger and ensure the unit operates within its specified BTU parameters. This part is a direct replacement for Lennox 54M90 gas orifices, facilitating a seamless transition to liquid propane while meeting strict HVAC safety and efficiency standards. Its brass construction provides excellent heat resistance, ensuring long-term reliability in high-temperature environments. Verify your specific manifold pressure requirements against the manufacturer’s data sheet to confirm this furnace gas orifice replacement diameter matches your installation needs.
Key Benefits:- Precision-machined 0.034-inch diameter for accurate propane fuel delivery.
- Ensures optimal fuel-to-air ratios to prevent carbon monoxide hazards.
- Constructed from high-grade brass to resist corrosion and thermal cycling.
- Facilitates direct OEM compatibility for Lennox gas valve conversions.
- Helps maintain consistent burner ignition and flame stability.
Is the Lennox 54M90 compatible with all Lennox residential furnaces?
No, compatibility depends on the specific model and the required BTU output. Always check the furnace rating plate and the LP conversion kit instructions to ensure the 0.034-inch sizing is correct for your altitude and manifold pressure.
Can I use this orifice for natural gas applications?
No, this orifice is specifically sized for LP gas conversion. Using a propane-sized orifice with natural gas will lead to under-firing and significant heating performance issues.
Does this part include the manifold or conversion springs?
This is a standalone furnace orifice. When converting a unit, you may also require a 36H/36G regulator spring kit and a new pressure switch, depending on the furnace series.
