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.
■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.
■The area around the LP tank must be free and clear
from debris.
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 the dust cover in place 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.
