❓ Frequently Asked Questions (FAQ)
Q: What does “B” mean in this nozzle model?
A: The “B” indicates a Solid Cone spray pattern, ideal for delivering full, even combustion in higher-flow burners.
Q: What is the purpose of the mesh strainer?
A: The mesh strainer traps larger fuel particles, preventing blockages and extending nozzle service life — particularly important in high-volume systems.
Q: Can I use this in smaller residential burners?
A: No. This nozzle is designed for high-capacity commercial or industrial burners due to its 12.00 GPH flow rate.
Q: How often should I replace it?
A: Replace annually or sooner if fuel quality is poor or you observe performance issues.
🛒 Shopping Tips
🧭 Match flow rate (GPH) and spray angle to your burner’s design requirements.
🔄 Spray Pattern Codes:
-
“A” = Hollow Cone – fine atomization for light oils.
-
“B” = Solid Cone – full-bodied spray for heavier oils or high firing rates.
-
“W” = Semi-Solid Cone – balanced for mixed conditions.
✅ Always confirm your nozzle type and angle before replacement to ensure proper combustion.
✔ Replace nozzles during annual maintenance for consistent burner performance.
✔ Handle carefully — never touch or clean the spray tip with sharp tools.
✔ Keep spares available, especially for high-demand commercial systems.
