Best for: Delavan adaptor users seeking a direct-fit upgrade. This nozzle is designed as a direct replacement for Delavan Nozzle Adaptor models 30609-5 and 17147, with an enhanced atomization profile for better combustion. It installs quickly without modifying the existing adaptor system.
Why selected: The upgrade focuses on improved fuel atomization, which can yield more efficient burning and cleaner exhaust when handling waste oil fuels.
Limitation: It is a direct-replacement product, so verify that your system uses the exact adaptor models referenced.
Oil Burner Nozzle 306095 for Reznor and More
Best for: multiple waste oil heater brands including Reznor, Clean Burn, EnergyLogic, Shenandoah. This nozzle matches part number 30609-5 and can be compatible with models that use this standard. It supports spray angle and droplet size adjustments via airflow and lift variations.
Why selected: Versatility across several established heater brands makes it a practical replacement option for facilities with mixed equipment.
Limitation: Spray characteristics can vary with system configuration; test adjustments to achieve the desired atomization for your fuel type.
Gxcdizx 2 Pack 30609-5 / 102997 Nozzle
Best for: Reznor, Clean Burn, EnergyLogic, Shenandoah, and similar waste oil heater brands. This nozzle replaces PN 30609-5 or 102997 and supports furnaces up to about 280,000 BTU/hr (roughly 2 GPH).
Why selected: The two-pack offers ready replacements for high-cycle usage and supports broad compatibility with common waste oil systems.
Limitation: Confirm the exact model compatibility for your unit prior to purchase to ensure a proper fit and spray performance.
Gxcdizx 0.5 mm Nozzle 30609-5

Buying Guide: Key Considerations For Waste Oil Nozzles
- Fuel compatibility: Confirm whether the nozzle supports heavy oil, waste oil, alcohol-based fuels, or blends used in your burners.
- Adaptor and model compatibility: Many nozzles are designed for specific adaptor models (Delavan, 17147, 30609-5, 102997, etc.). Verify your equipment’s model and fittings before purchase.
- Spray characteristics: Consider nozzle size (0.5 mm to 1.5 mm) and spray cone angle. Smaller diameters yield finer atomization; larger diameters provide higher flow.
- Material durability: Brass and high-quality metals improve life in tough environments; look for corrosion resistance and wear resistance.
- Installation and maintenance: Some nozzles come with seals or require simple seals replacements. Ensure you have the proper gaskets or o-rings for a tight seal.
Frequently Asked Questions
- Q: What nozzle size should I choose for waste oil burners? A: Size depends on fuel type and burner design. Common options range from 0.5 mm to 1.5 mm; smaller sizes for finer atomization and larger sizes for higher flow.
- Q: Are these nozzles interchangeable between brands? A: Not always. Check adaptor compatibility (Delavan, Reznor, Clean Burn, EnergyLogic, Shenandoah, etc.) before purchasing.
- Q: Do nozzle replacements require burner downtime? A: Yes, plan maintenance during or after operation hours to minimize disruption and ensure proper installation.
- Q: Can upgrading nozzles improve combustion efficiency? A: Improved atomization can lead to more complete combustion and potentially lower emissions, depending on system tuning.
- Q: Should I replace seals when changing nozzles? A: Replacing accompanying seals or gaskets is recommended to ensure a proper seal and spray consistency.
- Q: How do I verify compatibility with my specific boiler or heater model? A: Cross-check the part numbers (e.g., 30609-5, 102997) and model compatibility with your equipment’s manufacturer documentation.
