Most sore throats result from viral infections, usually colds, but possibly influenza. In children or adults who were not immunized, the measles, chickenpox or whooping cough can cause a sore throat.

Turn the valve on the propane tank one full turn counter-clockwise. I used to turn the valve as far as it could go until I learned that enough gas is released with just one rotation. In fact, it is safer to do this. If there is ever a problem, you will be able to turn it off and stop the flow of gas quickly. Turn the burner control that is closest to the ignition switch to High. Press the ignition switch one to two times to light the burner. If the grill does not light, turn off the burner and the propane.
