The difference in flame color on your Blackstone griddle could be due to several factors. Here’s a breakdown of potential causes and solutions:

1. Airflow Issues

• The air-to-gas mixture may be off. Each burner has an air shutter near the control knob or burner tube that regulates the airflow. If the right side has insufficient air, it can result in a yellow or orange flame.
• Solution: Check and adjust the air shutter. Open it slightly to allow more air into the mixture until you see a steady blue flame.

2. Clogged or Dirty Burner Tubes

• Grease, debris, or insects can clog the burner holes, affecting the flame.
• Solution: Turn off the gas and let the griddle cool completely. Remove the burner tubes and clean them with a wire brush or compressed air to clear any blockages.

3. Uneven Gas Pressure

• If the gas flow is uneven or restricted, it can cause one side to burn differently.
• Solution: Ensure the propane tank is connected securely, the regulator is functioning correctly, and there are no kinks or leaks in the gas line.

4. Grease or Residue Build-Up

• Grease dripping onto the burners can cause orange flames due to combustion of the grease.
• Solution: Inspect and clean the burners and ensure the grease tray is properly catching drips.

5. Environmental Factors

• High humidity, altitude, or wind can sometimes affect the flame color.
• Solution: Shield the burners from wind and try cooking in a more controlled environment to see if it improves.

If you’ve tried these steps and the issue persists, there could be a deeper issue with the burner assembly or regulator. In that case, you may want to contact Blackstone customer support or a professional technician for further assistance.
