Modine 5H0547510040 Orifice

The Modine 5H0547510040 Orifice is a precision-engineered Main LP Orifice specifically designed for high-performance liquid propane conversion and maintenance in industrial heating systems. As the direct replacement for 5H54751-40, this component is critical for regulating gas flow to ensure stoichiometric combustion and optimal thermal efficiency. Built to withstand the rigorous demands of HVACR environments, it maintains consistent manifold pressure and burner performance across a broad range of Modine unit heaters.

This LP gas orifice is compatible with several signature Modine series, including PV200, PV400, BV200, and BV400 models. It also serves as the correct specification for PAE, BAE, and DFG series units. For contractors performing field conversions or replacing fouled burner orifices, using this OEM replacement part ensures the heating system operates within the manufacturer's designated BTU input parameters, preventing over-firing or incomplete combustion in propane gas applications.

• Direct OEM Fit: Ensures seamless compatibility with Modine 5H54751-40 legacy parts.
• Precision Calibration: Engineered for accurate propane gas flow regulation in power-vented units.
• Enhanced Combustion: Optimizes burner efficiency to reduce carbon buildup and heat exchanger stress.
• Heavy-Duty Construction: Manufactured from high-grade materials to resist corrosion in commercial heating environments.

Which Modine models is the 5H0547510040 compatible with?
This Main LP Orifice is designed for Modine PV, BV, PAE, and BAE series, specifically covering sizes such as the PV200 and PV400. Always verify your BTU rating and manifold requirements before installation.

Can I use this orifice for a natural gas system?
