Important Information about
Natural Gas & Gas Connections
What is Natural Gas?
Natural gas (NG) is a combustible, gaseous mixture
of simple hydrocarbon compounds, usually found in
deep underground reservoirs formed by porous rock.
It is a fossil fuel composed almost entirely of methane.
Natural gas is delivered by your local utility through an
underground pipeline system.
General Specifications
Contact your local municipality for building codes
regulating outdoor gas grill installations. In absence of
Local Codes, you must conform 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.
WE RECOMMEND THAT THIS INSTALLATION BE DONE BY A
PROFESSIONAL.
• This grill is designed to operate at 4.0" of water column
pressure (0.144365 psi).
• 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.
• A manual shut-off valve must be installed outdoors, and be
accessible.
• An additional manual shut-off valve indoors should be
installed in the branch fuel line in an accessible location
near the supply line.
• Pipe compound that is resistant to the action of natural gas
should be used when connections are made.
• The outdoor connector must be firmly attached to rigid,
permanent construction.
Gas Line Piping
• If the length of the line required does not exceed 50 feet,
use a
5
⁄
" O.D. tube. One size larger should be used for
8
lengths greater than 50 feet.
• 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.
• 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.
Typical NG Grill Pipe Installation
INSIDE HOUSE
Gas supply
Shutoff
OUTSIDE HOUSE
1/2" Quick-disconnect
1/2" pipe nipple
Locking shutoff
Local codes may require
different installations.
Flare fittings should never
be used.

Hose Requirements
• The grill is equipped with a model specific hose that was
attached during the manufacturing process. This specific
hose must be used for proper performance.
• If the hose becomes worn or damaged, contact the
Customer Service Representative in your area using the
contact information on our website.
Pressure Testing the Gas Supply
• Disconnect the 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 the 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).
Hose Connection
Connect the Hose to the Gas Supply
A quick-disconnect fitting connects your grill to the gas
supply. Gas will not flow unless the quick-disconnect is
properly engaged.
1) Check that all burner control knobs are in the off
position. Check by pushing in and turning knobs
clockwise (A).
2) Starting from inside the cabinet, route the flexible gas
hose out of the opening in the rear panel (B).
3) Slide the collar of the quick-disconnect back (C).
4) Push male fitting of the hose into the quick-disconnect
and maintain pressure. Slide the collar closed (D). If it
does not engage or lock, repeat procedure. Proceed to
"CHECKING FOR GAS LEAKS".

DANGER: Do not line the slide-out grease tray or
cookbox with aluminum foil.
DANGER: Check the slide-out grease tray and
m
catch pan for grease build-up before each use.
Remove excess grease to avoid a grease fire.
WARNING: Use caution when removing catch pan
m
and disposing of hot grease.
m
WARNING: Use heat-resistant barbecue mitts or
gloves when operating grill.
WARNING: Grill brushes should be checked for
m
loose bristles and excessive wear on a regular
basis. Replace brush if any loose bristles are
found on cooking grates or brush. WEBER
recommends purchasing a new stainless steel
bristle grill brush at the beginning of every spring.
m
WARNING: Keep ventilation openings around tank
clear and free of debris.
m
WARNING: Keep any electrical supply cord and the
fuel supply cord away from heated surfaces.
