Several factors can lead to soot production in gas log fireplaces:

  • Dirty or Clogged Burners: Over time, food debris, dust, and other contaminants can accumulate on burners, preventing optimal gas flow.
  • Insufficient Oxygen: A lack of oxygen can cause a yellow, smoky flame and produce soot.
  • Incorrect Gas Pressure: Too high or too low gas pressure can result in incomplete combustion and soot production.
