❓ Frequently Asked Questions (FAQ)
Q: What does “A” mean in the nozzle number?
A: “A” indicates a Hollow Cone spray pattern for fine atomization and efficient mixing with air.
Q: Can I replace this with a solid cone nozzle?
A: Only if your burner’s design allows. Always follow the burner manufacturer’s recommended spray pattern and angle.
Q: How often should I replace the nozzle?
A: Typically once per heating season, or sooner if fuel quality is poor or performance declines.
Q: What is the function of the sintered filter?
A: It traps fine particles and prevents clogging, ensuring consistent spray and long nozzle life.
🛒 Shopping Tips
🧭 Match flow rate (GPH) and spray angle to your burner’s specifications.
🔄 Spray Pattern Codes:
-
“A” = Hollow Cone (fine atomization, light oils)
-
“B” = Solid Cone (higher capacity, heavier oils)
-
“W” = Semi-Solid Cone (balanced performance)
✅ Always ensure you’re selecting the correct pattern for your application.
✔ Replace your nozzle annually for optimal performance and safety.
✔ Handle carefully — avoid touching the spray orifice to prevent damage.
✔ Keep spare nozzles on hand for quick maintenance and seasonal tune-ups.
