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.
• Your natural gas grill is factory built to operate using
natural gas only. Never attempt to operate your grill on
gases other than the type specified on the grill rating
plates.
• This WEBER gas grill is designed for natural gas only.
Do not use liquid propane (LP) bottled gas. The valves,
orifices and hose are for natural gas only.
• Before using an NG grill, you need to make sure that
the branch supply line from your house to your grill is
properly installed.
• Not for use by children.
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).
• This grill is designed to operate at 7" of water column
pressure (.2526 psi).
• A manual shutoff valve must be installed outdoors,
immediately prior to the quick-disconnect.
• An additional manual shutoff valve should be installed
indoors in the branch fuel line, in an accessible location
near the supply line.
• The quick-disconnect connects to a 3/8" NPT thread
from the gas source. The quick disconnect fitting
is a hand-operated device that automatically shuts
off the flow of gas from the source when the grill is
disconnected.
• The quick-disconnect fitting can be installed
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 fitting.
• The dust covers (plastic plugs supplied with your grill)
help keep the open ends of the quick-disconnect fitting
clean while disconnected.
• When making connections, only use pipe compound
that is resistant to the action of natural gas.
• The outdoor connector must be firmly attached to rigid,
permanent construction.
m WARNING: Do not route the ten-foot hose
under a deck. The hose must be visible.
• For the correct size and length of gas line piping, refer
to the latest edition of the National Fuel Gas Code: ANSI
Z 223.1/NFPA 54, or CAN/CGA-B149.1, Natural Gas and
Propane Installation Code.
• Gas piping may be copper tubing, type K or L;
polyethylene plastic tube, with a minimum wall
thickness of .062"; or standard weight (schedule 40)
steel or wrought-iron pipe.
• Copper tubing must be tin lined if the gas contains
more than 0.3 grams of hydrogen sulfide per 100 cubic
feet of gas.
IMPORTANT INFORMATION ABOUT NATURAL GAS
• Plastic tubing is suitable only for outdoor, underground
use.
• Gas piping in contact with earth, or any other material
which may corrode the piping, must be protected
against corrosion in an approved manner.
• Underground piping must have a minimum of 18" cover.
STORAGE AND/OR NONUSE
The gas must be turned off at the natural gas supply when
the WEBER gas grill is not in use.
• If storing the WEBER gas grill indoors, first
DISCONNECT the gas supply.
For grills that have been stored or left unused for a while, it
is important to follow these guidelines:
• The WEBER gas grill should be checked for gas leaks
and any obstructions in the burner tubes before it is
used. (Refer to "ANNUAL MAINTENANCE.")
• Check that the areas under the cookbox and the
removable catch pan are free from debris that might
obstruct the flow of combustion or ventilation air.
• The spider/insect screens should also be checked for
any obstructions. (Refer to "ANNUAL MAINTENANCE.")
PRESSURE TESTING GAS SUPPLY
• Disconnect your WEBER 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).
• Turn off your WEBER 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.
MEXICO INSTALLATION CODES
If there are local codes that apply to portable gas grills, you
must comply with the latest edition of NOM.
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 the latest edition of Standard CAN/
CGA-B149.1 (Natural Gas and Propane Installation Code).
