WHAT IS NATURAL GAS?
Natural gas (NG) is often
called methane. Natural
gas is supplied by your local
utility and should be readily
available if your house is
already heated with gas.
NATURAL GAS — THE BASICS
There are various guidelines and safety factors that
you need to keep in mind when using natural gas (NG).
Carefully follow these instructions before using your
Weber
®
gas grill.
• Yournaturalgasgrillisfactorybuilttooperateusing
natural gas only. Never attempt to operate your grill on
gases other than the type specied on the grill rating
plates.
• ThisWeber
®
gas grill is designed for natural gas
only. Do not use liquid propane (LP) bottled gas. The
valves, orices and hose are for natural gas only.
• BeforeusinganNGgrill,youneedtomakesurethat
the branch supply line from your house to your grill is
properly installed.
• Notforusebychildren.
PIPING SPECIFICATIONS
Contact your local municipality for building codes
regulating outdoor gas grill installations. In the absence of
local codes, installation must conform to the latest edition
of the National Fuel Gas Code: ANSI Z223.1/NFPA 54, or
CAN/CGA-B149.1, Natural Gas and Propane Installation
Code. WE RECOMMEND THAT THIS INSTALLATION BE
DONE BY A PROFESSIONAL.
Following are some general requirements taken from the
code(s).

• Anadditionalmanualshutoffvalveshouldbeinstalled

location near the supply line.
• Thequick-disconnectconnectstoa3/8"NPTthread
from the gas source. The quick disconnect tting
is a hand-operated device that automatically shuts
off the ow of gas from the source when the grill is
disconnected.
• Thequick-disconnectttingcanbeinstalled
horizontally or pointing downward, but never pointing
upward. Installing it with the open end pointing upward
can result in water and debris collecting in the quick-
disconnect tting.
• Thedustcovers(plasticplugssuppliedwithyourgrill)

STORAGE AND/OR NONUSE
For grills that have been stored or left unused for a while,
it is important to follow these guidelines:
• Thegasmustbeturnedoffatthenaturalgassupply
when the Weber
®
gas grill is not in use.
• IfstoringtheWeber
®
gas grill indoors, rst
DISCONNECT the gas supply.
• TheWeber
®
gas grill should be checked for gas leaks
and any obstructions in the burner tubes before it is
used. (Refer to “ANNUAL MAINTENANCE.”)
• Checkthattheareasunderthecontrolpanelandthe
slide-out grease tray are free from debris that might
obstruct the ow of combustion or ventilation air.
• Thespider/insectscreensshouldalsobe
checked for any obstructions. (Refer to “ANNUAL
MAINTENANCE.”)
PRESSURE TESTING GAS SUPPLY
• DisconnectyourWeber
®
gas grill 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).
• TurnoffyourWeber
®
gas grill 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 test
pressures equal to or less than 1/2 psig (≤3.5 kPa).
CONNECTION TESTING
All connections and joints must be thoroughly tested
for leaks in accordance with local codes and all listed
procedures in the latest edition of the National Fuel Gas
Code: ANSI Z223.1/NFPA 54, or CAN/CGA-B149.1.
US INSTALLATION CODES
Installation must conform with local codes or, in the
absence of local codes, with either the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, Natural Gas and Propane
Installation Code, CSA B149.1; or Propane Storage and
Handling Code, B149.2; or the Standard for Recreational
Vehicles, ANSI A 119.2/NFPA 1192, and CSA Z240 RV
Series, Recreational Vehicle Code, as applicable.
CANADIAN INSTALLATION
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 Standards CAN/CGA-B149.1
(Installation Code for Natural Gas Burning Appliances and
Equipment).
