If your grill is not getting hot enough to cook, the gas flow limiting device may have been activated. You will need to reset your regulator by doing the following: 1. Turn ALL burner control knobs to the OFF position and turn off the propane tank valve. 2. Disconnect the hose and regulator from the propane tank. Wait 2 minutes. 3. Reattach the hose and regulator and perform a leak test.
