Reznor 102997 Siphon Nozzle

The Reznor 102997 Siphon Nozzle is a critical OEM replacement part engineered for precise fuel atomization in Reznor waste oil heaters. Built by Delavan (Part Number 30609-5 or 30609-7), this all-brass component utilizes compressed air to lift and atomize fuel, creating a stable, high-efficiency combustion flame. As a veteran-grade burner nozzle, it is optimized for high-viscosity fuels, ensuring a consistent spray pattern that minimizes soot buildup and prevents electrode fouling. This siphon-actuated nozzle is a direct match for RA, RAD, and RV series equipment, specifically rated for models like the RA 140, RA 235, and RV 225. Regular replacement every 2,000 hours is recommended to maintain peak waste oil heater performance and prevent misfires caused by internal debris or orifice wear. Using this genuine waste oil burner part ensures your system meets original factory specifications for flow rate and spray angle, maintaining energy-efficient combustion across all elevation settings.

• Precision Atomization: Specifically designed for siphon-fed waste oil burners, providing a solid cone spray pattern for clean ignition.
• Broad Compatibility: Fits Reznor RA/RAD 140, 235, 250, and RV 225/325 models, as well as several alternative waste oil furnace brands.
• Industrial Durability: Machined from high-grade brass to withstand the abrasive nature of recycled oils and prevent premature clogging.
• Combustion Stability: Engineered to hold tight tolerances, reducing flame flickering and ensuring even heat distribution in the unit heater.

When should the siphon nozzle be replaced?
In most commercial applications, the nozzle should be swapped every 2,000 service hours or annually to prevent poor atomization and excessive soot accumulation.

Is this nozzle suitable for high-altitude installations?
Yes, the 102997 is rated for RA 140 models up to 3,000 feet and RAD 235/250 models at all elevations, providing stable performance regardless of atmospheric pressure.

Can I use this for fuels other than waste oil?
While designed primarily for waste oil, it is a versatile siphon nozzle often used in applications requiring low-pressure air atomization of varying fuel viscosities.
