Ensure that the propane tank has fuel in it by reading the weight scale next to the tank.
Inspect the entire length of the fuel hose, from the propane tank to the burner assembly, for sharp bends.
Light the burners, then preheat the barbeque by turning all of the burner knobs to the “Hi” position for 10 to 15 minutes.
Inspect the stainless steel spider screens for any blockages which could be preventing the gas from reaching the burner. The spider screens are located at the tip of each burner tube. To access the screens, the control panel must be removed. Turn the valve on top of the propane tank to the “Off” position. Pull each control knob off of the panel, then remove the single screw from the back of the control panel with a Phillips-head screwdriver. Raise the back of the control panel slightly, then push in on the front of the control panel and lift the panel off of the barbeque to reveal the burner tubes. Look into the tip of each tube with a flashlight to inspect the screens. Clean the screens with a soft bristle brush, such as an old toothbrush.
Reset the excess flow safety device. Turn all of the burner knobs to the “Off” position, then turn the valve on top of the propane tank to the “Off” position. Disconnect the regulator valve from the top of the propane cylinder. Turn each of the burner knobs to the “Hi” position and allow at least one minute to expire. Turn the burner knobs to the “Off” position and reconnect the regulator valve to the propane tank. Turn the valve on top of the propane tank to the “On” position slowly.
