Burner Flames Abnormal Colors - Natural Gas

Is an ultrasonic humidifier used in the house? 

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

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

Is the burner base and burner cap positioned properly? 

The cap must be seated on the burner base to light and perform properly. Be sure the correct burner cap is on the correct burner base.  The burner base and the underside of the burner cap may have a mark indicating which burner cap and burner base match.  The burner cap should fit flush with the base and have minimal side-to-side movement.  

Always keep the burner cap in place when using a surface burner. A clean burner cap, especially the bottom, will help avoid poor ignition and uneven flames. Always clean the burner cap after a spillover and routinely remove and clean the caps.

Are the burner ports clogged?

Clean clogged burner ports with a straight pin, needle, or small gauge wire as shown.

• Do not use a wooden toothpick; it can break off and prevent proper gas flow. 
• Do not clean in the dishwasher.
• Do not enlarge or distort the port.
