Which of the following are signs of a malfunctioning propane burner?

• A. Bright blue flames
• B. Yellow flames, soot buildup, or poor combustion
• C. No flames
• D. Constant loud noise

Answer: (B)

A malfunctioning propane burner typically displays signs that indicate improper combustion. Yellow flames, for instance, suggest that the burner is not achieving complete combustion, which can happen due to an incorrect air-to-fuel mixture. This yellow coloration is indicative of unburned fuel and may lead to soot buildup inside the burner or on nearby surfaces. Soot is a byproduct of incomplete combustion and presents a safety hazard as it can impede ventilation and create a fire risk. Poor combustion can also lead to increased emissions of carbon monoxide, making it a critical concern from a safety perspective. While bright blue flames typically indicate efficient and complete combustion, they are not a sign of malfunction. No flames would clearly indicate a failure of the burner to ignite or operate, and a constant loud noise could suggest a mechanical issue but is not a standard indicator solely related to the combustion process of the burner itself.
