Cause

This is normal behavior caused by water vapor as a byproduct of combustion. The fog may last slightly longer in colder weather.

Resolution

  • The Flame Visibility window fog will clear on its own within 30 seconds to 1 minute after ignition.
  • Cold weather can cause the fogging to take slightly longer to clear.
  • Fog will clear once the window temperature increases (much like the defrost on a windshield).
