Weber natural gas grills are designed to be portable so that you can easily unhook the grill and change its location or take the grill with you during a move. You will need a natural gas supply to use the grill which you should already have if your home uses gas for heating purposes. Contact your gas company to install a new gas connection if one does not exist where you would like to operate the grill.
Position the grill at least two feet away from the natural gas connection.
Remove the cap from the natural gas connection if one exists. These caps can usually be twisted off or pulled off easily.
Pull back the outer fitting on the end of the flexible natural gas hose attached to the grill. This hose was attached to the grill during manufacturing.
Keep the outer fitting pulled back and insert the end of the hose into the natural gas connection as far as possible.
Release the outer fitting. The outer fitting will move forward and cover the connection forming a gas joint.
Check for gas leaks by spraying soapy water onto the hose and the connection area. If bubbles form then gas is escaping and the hose has been connected improperly.
Do not attempt to use liquid propane in a Weber natural gas grill. This could be dangerous and will void the manufacturer's warranty.
