General Instructions

Your Weber Gas Barbecue is a stationary 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 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 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 and orifices 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.

Storage

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

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 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 testing of that system at test
pressures in excess of 1/2 psig (3.5 kPa).

Turn off your Weber Gas Barbecue when the gas
supply is being tested at low pressures. This appliance
must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at the
pressure equal to or less than 1/2 psig (3.5 kPa).
