REFER TO YOUR STEP-BY­STEP GUIDE AT THIS TIME
FOR BARBECUE ASSEMBLY

WA R N I N G : Make sure your barbecue is set up pro p e r ly
and leak ch e cked before attempting to operate.

Your Weber Gas Barbecue is a portable outdoor cooking
appliance. With the Weber Gas Barbecue you can grill,
barbecue, roast and bake with results that are difficult to
duplicate with indoor kitchen appliances. The closed lid and
Flavorizer Bars produce that "outdoor" flavor in the food.

The Weber Gas Barbecue is portable so you can easily
change its location in your yard or on your patio.
Portability means you can take your Weber Gas
Barbecue with you if you move.

The natural gas supply is easy to use and gives you more
cooking control than charcoal fuel.

■ These instructions will give you the minimum

requirements for operating and maintaining your
Weber Gas Barbecue. Please read the instructions
carefully before using your Weber Gas Barbecue.
Improper assembly can be dangerous.

■ Not for use by children.

■ If there are local codes that apply to portable gas

grills, you will have to conform to them. If there are no
local codes, you must conform to the latest edition of
the National Fuel Gas Code: ANSI Z 223.1.

■ This Weber Gas Barbecue is designed for natural

(piped in city) gas only. Do not use Liquid Propane
(LP) bottled gas.The valves, orifices and hose are for
natural gas only.
