Reznor 9680 Carryover Orifice

Ensure reliable ignition across your unit heater’s burner rack with the Reznor 9680 Carryover Orifice. This genuine #65 replacement carryover orifice is specifically engineered to regulate fuel flow within the lighter tube assembly, providing the precise gas velocity required for consistent flame propagation between burners. Designed for high-performance Reznor HVAC parts maintenance, this brass component is a critical fix for delayed ignition or uneven heating issues in industrial and commercial gas-fired units.

As a veteran tech, you know that a clogged or oversized carryover lighter tube orifice can lead to soot accumulation or burner lockout. The Reznor 9680 ensures OEM-spec combustion efficiency and is compatible with a wide range of legacy and modern models, including the RP, XE, and HRPD series. Integrating this OEM Reznor burner part into your service routine prevents unnecessary wear on the ignition system and maintains the structural integrity of the heat exchanger by ensuring stable flame patterns.

• Precise Fuel Regulation: Factory-drilled #65 sizing ensures the exact BTU input for the carryover assembly.
• Burner Rack Stability: Facilitates smooth flame "carryover" from the pilot to all burner sections.
• OEM Compatibility: Precision-fit for Reznor RP 200, XE 150, SCE 225, and HRPD series unit heaters.
• Durable Brass Construction: Resists corrosion and thermal stress in high-heat combustion environments.

What are the symptoms of a failing Reznor 9680 orifice?
Technicians typically observe delayed ignition across the burner rack or a "lazy" yellow flame in the carryover tube, which indicates a block or incorrect orifice sizing.

Is this part suitable for both Natural Gas and Propane units?
The #65 orifice is generally used for specific gas manifold pressures; always verify your unit's rating plate and gas type against the manufacturer's orifice chart before installation.

Can I drill out the orifice to increase flow?
Never attempt to field-drill a carryover orifice. This compromises the engineered combustion sequence and can lead to dangerous gas buildup or equipment damage. Always use genuine Reznor components.
