Nordyne 661055R Orifice
The Nordyne 661055R Orifice is a precision-engineered #55 drill main burner orifice designed to maintain consistent manifold pressure and gas flow in high-efficiency heating systems. As a veteran HVACR technician knows, precise gas metering is critical for achieving a clean blue flame and preventing incomplete combustion or sooting. This OEM main burner orifice serves as the direct replacement for the legacy part 661055, ensuring that gas velocity and air entrainment meet the strict factory specifications for Nordyne, Miller, and Intertherm furnaces.
Constructed from durable brass, the Nordyne 661055R is frequently utilized in natural gas applications or specialized high-altitude conversion kits where a #55 drill size is specified for derating. It is compatible with a broad range of Nordyne heating equipment, including M2 and M7 series models. Installing this genuine Nordyne replacement part ensures the burner assembly operates at its design-rated BTU output, preserving system longevity and operational safety for residential and manufactured housing installations.
Key Benefits- Precision Gas Metering: The #55 drill size ensures accurate fuel delivery for stable combustion and optimal thermal transfer.
- Direct OEM Fitment: Eliminates the risks of using non-standard spuds, ensuring the Nordyne 661055R seats perfectly into the burner manifold.
- Wide Compatibility: Tailored for use in furnaces under brands like Miller, Intertherm, and Frigidaire, making it a versatile tool-bag essential.
- Reliable Heat Output: Maintains factory-specified BTU ratings to prevent under-firing or hazardous over-firing conditions.
Is this orifice used for natural gas or propane?
The #55 drill size is typically utilized for natural gas at standard elevations or for propane in specific high-altitude conversion scenarios. Always consult the equipment rating plate and local altitude charts for exact manifold pressure requirements.
Can I use this for high-altitude derating?
Yes, in many Nordyne and Miller units, the #55 orifice is the specified component for installations between 2,000 and 7,000 feet to account for thinner air and maintain safe combustion ratios.
What symptom indicates a blocked or incorrect orifice?
Weak, yellow-tipped flames or consistent ignition failures often point to a clogged or improperly sized orifice. Replacing a fouled part with a 661055R restores the high-velocity gas stream needed for proper primary air mixing.
