💡 Common Symptoms of a Failing or Clogged Nozzle
-
🔥 Unstable or distorted flame pattern
-
⚫ Black smoke or soot on electrodes or heat exchanger
-
⏱️ Delayed ignition or noisy starts
-
⚠️ Frequent burner lockouts or irregular flame signal
-
💧 Fuel dripping or incomplete atomization
🛠️ Shopping Tips
-
“A” = Hollow Cone → finer atomization, ideal for low firing rates or shallow chambers
-
“B” = Solid Cone → denser spray for larger chambers
-
Match flow rate (GPH) and spray angle (°) to burner requirements
-
Keep extra nozzles on hand for maintenance intervals
-
Avoid touching orifice — handle carefully to prevent contamination
