How do I adjust a gas grill regulator?
Regulator VentShut off the gas valve on the grill before you begin working to avoid any disastrous accidents. Turn the hex bolt on the regulator using a wrench until the vent on the regulator is pointing downward, thus preventing rain, dust or debris from entering the regulator, which is the only way you can service the regulator without removing it. Adjustment can vary depending on the model; read the manual thoroughly before you begin. Letting a professional handle this is highly recommended. After adjusting, turn the gas back on.
