The flames of a gas barbecue/grill should be blue in normal operation. If the flames are yellow, there is a problem with the regulator. Fortunately, this is quite easy to check and repair:
- Turn off the burners.
- Turn off the gas cylinder, then disconnect the regulator from the cylinder.
- You can reconnect the regulator to the gas cylinder.
- Open the cylinder and check that there is no gas leakage from the regulator.
- Then relight the burners and check the colour of the flame.
If the problem persists, there must be a problem with the regulator.
If the regulator has been changed, please open a service request if your product meets the requirements.
