Reznor 10370 Orifice
The Reznor 10370 Carryover Orifice is a precision-engineered gas burner component designed specifically for industrial and commercial heating systems. Featuring a drill size #59, this orifice is critical for ensuring reliable pilot-to-burner ignition and maintaining stable combustion cycles in Reznor unit heaters. As a veteran HVAC technician knows, precise orifice sizing is vital to prevent delayed ignition or nuisance lockouts, especially in forced air gas heaters where consistent pressure regulation is required. This carryover tube orifice is constructed from high-quality brass to resist thermal fatigue and corrosion within the burner assembly. Whether you are performing a seasonal tune-up or a specific gas heater repair, replacing a clogged or oversized pilot orifice with the OEM-specified 10370 ensures the unit operates within the manufacturer’s design parameters for BTU output and flame stability. Ensure the burner manifold is clear of debris before installation to maintain optimal flow through the #59 porting.
Key Benefits for Technicians- Precise Drill Size #59: Engineered for accurate gas metering to ensure consistent carryover performance.
- Durable Brass Construction: Built to withstand the high-temperature environment of the burner tray without degrading.
- Standard Reznor Compatibility: Direct replacement for part number 10370 to minimize downtime during service calls.
- Optimized Ignition: Promotes smooth flame transfer across burner ribbons for efficient startup.
What happens if I use the wrong orifice drill size?
Using a size other than the specified #59 can lead to improper flame carryover, resulting in delayed ignition or incomplete combustion, which triggers safety sensors.
How do I identify a failing carryover orifice?
Look for signs of carbon buildup, partial blockages, or physical warping that prevents the pilot flame from reaching the main burner effectively.
Is this orifice compatible with propane (LP) conversions?
Orifice sizing is gas-type specific; always verify the required drill size against the appliance rating plate when converting from natural gas to liquid propane.
