Reznor 64676 Orifice
The Reznor 64676 Orifice is a critical 1.30 mm brass component engineered for high-performance propane (LP) burner applications. As an authentic Reznor OEM replacement part, this orifice is designed specifically for commercial and industrial gas-fired unit heaters. In the field, achieving precise fuel atomization is essential for stable combustion and maximizing heat exchanger longevity. This precision-machined LP burner orifice ensures the correct manifold pressure and gas flow rate, preventing common issues like soot accumulation, delayed ignition, or incomplete combustion in propane conversion kits.
For veteran technicians performing a Reznor heater tune-up, using factory-spec components is non-negotiable for maintaining system safety and meeting strict factory performance standards. This 1.30 mm orifice provides the exact restriction required for LP gas densities, eliminating the guesswork associated with generic alternatives. Whether you are conducting a seasonal inspection or a complete fuel conversion, the 64676 orifice provides the durable, industrial-grade construction necessary to withstand the high-temperature environments of professional HVAC installations.
Key Benefits- OEM Precision: Guaranteed 1.30 mm sizing for accurate fuel-to-air ratios.
- Durable Brass Construction: High-quality material resists corrosion and thermal stress.
- System Efficiency: Promotes complete fuel atomization to lower operational costs.
- Easy Installation: Standard threading for rapid replacement in the field.
- Can I use this orifice for natural gas systems? No, this is specifically calibrated for LP (liquid propane) systems.
- Is it safe to drill out this orifice? Never drill or modify a burner orifice; use only factory-supplied specifications for safety.
- What tools are required for replacement? A standard 9/16" open-end wrench is typically used to remove and seat the orifice on the manifold.
