It is important to have an even amount of oxygen and gas mixture for obtaining a perfect blue flame and ideal temperature from your outdoor grill. If the flame is yellowish, then that’s a sure sign of an imbalance in the gas to air ratio.
Most gas grills come equipped with a valve to adjust its airflow, usually located at the very end of the cooking unit near the valve itself. You must have an even balance of gas and oxygen for attaining the ideal heat temperature and blue flame. If there is a blockage of airflow in gas ratio, the flame will be yellow in color. Should your gas grill refuses to ignite, try checking out the gas mixture, and adjust as needed.
Depending on the type of grill, you might first have to remove its burner for easier access to the control panel. Some grill models might have hard-to-reach panels that are easier to access from elsewhere. Near burners, you will see a control valve, this is for adjusting the airflow of the outdoor gas grill; some have a metal knob to open and close. In case your shutter is metal, chances are that it has a screw for making any necessary adjustments.
First, replace the gas grill burner and test flame to see if it’s blue or not. Then if everything is good to go, take the burner back off and proceed to tighten up the screw for secure setting change. Replace burners and make adjustments so they have the same exact setting. It is possible to make changes while your outdoor gas grill’s turned on. Thus, giving you a better view of the flame during airflow adjustments and leaving less room for error.
