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.

Liquid Propane (LP) 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.

The pressure regulator supplied with the Weber Gas
Barbecue must be used. This regulator is set for
10.5 inches of water column (pressure).

This Weber Gas Barbecue is designed for use with
liquid propane (LP) gas only. Do not use with
natural (piped in city) gas. The valves, orifices, hose
and regulator are for LP gas only.

Do not use with charcoal fuel.

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-B149.2
(Installation Code for Propane Burning Appliances and
Equipment).

Storage

The gas must be turned OFF at the LP tank when
the Weber Gas Barbecue is not in use.

When the Weber Gas Barbecue is stored indoors,
the gas supply must be disconnected and the LP
tank stored outdoors in a well-ventilated space.

LP tanks must be stored outdoors in a well-
ventilated area out of the reach of children.
Disconnected LP tanks must have threaded valve
plugs tightly installed and must not be stored in a
building, garage or any other enclosed area.

When the LP tank is not disconnected from the
Weber Gas Barbecue, the appliance and LP tank
must be kept outdoors in a well-ventilated space.

Operating area

WARNING: Only use this barbecue outdoors in a
well ventilated area. Do not use in a garage,
building, breezeway or any other enclosed area.

Never use your Weber Gas Barbecue under an
unprotected combustible roof or overhang.

Your Weber Gas Barbecue is not intended to be 

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.

The entire cooking box gets hot when in use. Do not
leave unattended.

Keep any electrical supply cord and the fuel supply
hose away from any heated surface.

Keep the cooking area clear of flammable vapors
and liquids, such as gasoline, alcohol, etc., and
combustible materials.

Never store an extra (spare) LP tank under or near
the Weber Gas Barbecue.
