Gas Burner Flame Quality with Home Humidifier

Core Issue:

  • Will a humidifier, or humidifier system installed with the home furnace effect surface burner flames?
  • What will cause orange, uncrisp flames?
  • High yellow flame on all burners
  • Abnormal flames
  • Orange flame
  • Flame is orange
  • Yellow flames

Steps to Verify Issue:

A home humidifier can change the secondary air mixture resulting in an abnormal flame quality as shown below.
  • This may cause the flame quality to be un-crisp, and orange.
  • Turn the humidifier off for 24 hours and recheck flame quality.


Adjusting the setting on the home humidifier may impact flame quality. Factory Certified Service can adjust the flame to a certain extent, but there is no guarantee the flame quality issues will be eliminated.

If these steps do not resolve the issue, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
