Amana-Goodman B2589345 Orifice

The Amana-Goodman B2589345 Burner Orifice is a precision-engineered #45 drill size orifice designed specifically for natural gas burner manifolds. Engineered to meet exact OEM specifications, this component ensures the correct BTU input and gas flow rate for residential and light commercial Amana and Goodman gas furnaces. Maintaining the proper gas pressure and combustion efficiency depends on the integrity of the orifice; a clogged or improperly sized natural gas burner orifice can lead to incomplete combustion, soot buildup, or manifold pressure imbalances. For technicians performing furnace gas valve adjustments or natural gas manifold repairs, the B2589345 provides a direct fit to restore factory-standard performance. This brass fitting is built to withstand high-temperature furnace environments, ensuring consistent thermal output and reliable ignition cycles across compatible HVAC heating systems. Always verify the manifold gas pressure using a manometer after installation to ensure optimal burner alignment and safety.

• OEM Compatibility: Designed for seamless integration with Amana and Goodman furnace manifolds requiring #45 sizing.
• Precision Gas Metering: Delivers accurate natural gas flow to the burner assembly for standardized heat exchange.
• High-Grade Construction: Manufactured from heavy-duty brass to resist corrosion and thermal warping during furnace operation.
• Direct Replacement: Simplifies HVAC service calls by providing a direct match for Amana-Goodman B2589345 specifications.

What is the drill size for the B2589345 orifice?
This is a standard #45 drill size orifice calibrated for natural gas applications in specific furnace models.

Can I use this orifice for a propane conversion?
No, this part is specifically for natural gas burner systems. Propane (LP) conversions require a different orifice size and specific LP conversion kits to account for higher gas density.

How do I know if this orifice is clogged?
Visible soot, delayed ignition, or irregular flame patterns often indicate a blockage within the burner orifice that may require cleaning or replacement to restore proper combustion safety.
