General Instructions
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 assembling 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.
■Do not use with charcoal fuel.
■Check that the area under the control panel and the
bottom tray are free from debris that might obstruct
the flow of combustion or ventilation air.
For Installation in Canada
These instructions, while generally acceptable, do not
necessarily comply with the Canadian Installation codes,
particularly with piping above and below ground. In
Canada the installation of this appliance must comply with
local codes and/or Standard CAN/CGA-B149.1 (Installation
Code for Natural Gas Burning Appliances and Equipment).

■The gas must be turned OFF at the natural gas supply
when the Weber Gas Barbecue is not in use.
■When the Weber Gas Barbecue is stored indoors, the
gas supply must be disconnected.

well ventilated area. Do not use in a garage, building,
breezeway or any other enclosed area.

unprotected combustible roof or overhang.

installed in or on recreational vehicles and/or boats.
■Do not use combustible materials within 24 inches of
the top, bottom, back or sides of the grill.

leave unattended.

hose away from any heated surface.
■Keep the cooking area clear of flammable vapors and
liquids, such as gasoline, alcohol, etc., and
combustible materials.
Gas supply testing
■Disconnect your Weber Gas Barbecue when the gas
supply is being tested at high pressures. This appliance
and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure

1/2 psig (3.5 kPa).
■Turn off your Weber Gas Barbecue when the gas
supply is being tested at low pressures. This appliance
