Nordyne 661044 Orifice

Product Description

The NORDYNE 661044 is a replacement orifice designed for use in gas heating systems. An orifice meters the flow of gas from the manifold into the burner, directly affecting combustion efficiency and heat output. This precision-drilled fitting must match the fuel type and BTU rating of the appliance to ensure proper ignition and flame characteristics. Installation is typically performed by a licensed HVAC technician or gas service professional as part of a fuel conversion or routine maintenance procedure.

This orifice is suited for residential gas furnace applications where the original orifice has worn, been damaged, or requires replacement as part of a natural gas or LP fuel conversion. It is intended as a direct OEM replacement component within compatible NORDYNE heating equipment.

Key Features

• Precision-drilled orifice opening for accurate gas metering
• OEM replacement part sourced directly from NORDYNE
• Designed to maintain proper fuel-to-air ratio for efficient combustion
• Compact fitting suitable for standard burner manifold configurations

Compatibility

Designed as an OEM-style replacement orifice for NORDYNE residential gas furnace systems. Consult the equipment nameplate and service documentation to confirm orifice size and fuel type before installation.

Installation Notes

Orifice replacement must be performed by a qualified gas technician following all applicable local codes and IFGC requirements. Shut off the gas supply completely and verify zero pressure at the manifold before removing the existing orifice. Use the correct wrench size to avoid damaging the orifice threads or manifold. Never substitute an orifice of an incorrect size, as improper gas metering creates a combustion hazard.
