Noisy or Yellow flames - Commercial Range

Possible Solutions

Flames are Noisy/Yellow:

Compare the flame to the illustrations below. If the flames look like A:

  • A burner port (hole) may be clogged.  
  • Check to be sure the burner caps are positioned correctly.
  • If LP (propane) gas is being used, the cooktop may have been converted improperly; call for service. 

Normal flames look like B or C.

Is an ultrasonic humidifier used in the house? 

An ultrasonic humidifier in the home can create water vapor mist that carries minerals into the air. When passed through a flame, the minerals can create different flame colors. The humidifier does not need to be located near the range for it to affect the flame color.  Using distilled water will reduce the effect on the flame appearance. 

  • Calcium can produce an orange or red color.
  • Potassium can produce a lilac or pink color. Potassium is found in natural water and is also used in some water softeners.
