🔥 Soot buildup in the burner chamber or flue.
🔥 Increased fuel use or reduced system efficiency.
🔥 Plugging or uneven fuel spray pattern.
🔥 Inconsistent burner ignition or short cycling.
❓ Frequently Asked Questions (FAQ)
Q: What does “W” mean in the nozzle number?
A: “W” identifies a Semi-Solid Cone spray pattern, offering a balanced atomization suitable for varied burner designs and firing rates.
Q: What is the best use case for a semi-solid cone nozzle?
A: It performs well in systems that benefit from both the fine atomization of hollow cones and the even coverage of solid cones.
Q: How often should the nozzle be replaced?
A: Typically once per heating season, or more frequently if fuel contamination or poor combustion occurs.
Q: What’s the benefit of the sintered filter?
A: It captures fine particles before they reach the nozzle tip, preventing blockages and ensuring consistent performance.
🛒 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 (steady, full spray for heavier oils)
-
“W” = Semi-Solid Cone (balanced for varied conditions)
✅ Always confirm your system’s required spray pattern and angle before replacement.
✔ Replace your nozzle annually or during routine maintenance.
✔ Handle the nozzle carefully—avoid touching the spray tip.
✔ Keep spare nozzles on hand for quick maintenance and seasonal service.
