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).

General Specifications for Piping
American National Standards Institute (ANSI)
Recommendations for gas supply installations:
Connections:
■ This barbecue is designed to operate at 7 inches of
water column pressure (.2526 psi).
■ A manual shut-off valve must be installed outdoors,
immediately ahead of any connections or change in
pipe material.
■ An additional manual shut-off valve indoors should be
installed in the branch fuel line in an accessible
location near the supply line.
■ The point of tie into the branch line should be carefully
selected to avoid a drip leg or be downstream of a
valve controlling another appliance.
■ Pipe compound should be used which is resistant to
action of natural gas when connections are made.
■ The outdoor connector must be firmly attached to
rigid, permanent construction.
Gas line piping
■ If the length of line required does not exceed 50 feet,
use a 5/8" O.D. tube. One size larger should be used
for lengths greater than 50 feet.
■ Indoor and above ground piping can be steel
or copper.
Steel
New standard weight (Schedule 40) steel pipe with
malleable iron fittings.
Copper
New copper tubing type K or L.
Copper tubing must meet requirements of ASTM B88
latest edition.
Use flared fittings. Metallic ball sleeve compression fittings
must not be used.
Copper tube joints may be soldered or brazed with
material having a melting point in excess of 1,000°F.
Outside underground piping
Outside underground piping may be copper tubing, type K
or L (ASTM B88) or polyethylene plastic tube PE3306
(Minimum wall thickness .062") meeting ASTM 2513,
latest specifications.
Steel pipe is not recommended for underground use
unless it is protected with an approved coating, insulated
from hose piping and cathodically protected.
It is recommended that copper tubing be corrosion
protected with a satisfactory material such as TC Mastic.
All buried fittings should be corrosion protected with a
satisfactory material such as TC Mastic.
Underground piping must have a minimum of 10" cover.
Plastic tubing
Plastic tubing is suitable only for outside underground use.
■ The transition from metallic pipe to plastic pipe should
be made outside and at least 10" underground.
■ When compression or crimp type mechanical joints
are used with plastic pipe, it is advisable to use an
internal rigid stiffener in conjunction with the fitting.
■ The stiffener should be assembled flush with the end
of the tube and extend at least to the outside edge of
the compression fitting.
Testing connections
You will need a soap and water solution and a rag or
brush to apply it.
All connections and joints must be thoroughly tested for
leaks after gas has been turned into the line.
Notice Before Installation
Contact your local municipality for any building codes regulating outdoor barbecue installations. In absence of
local codes, you must conform to the latest edition of ANSI Z223.1.
WE RECOMMEND THAT THIS INSTALLATION BE DONE BY A PROFESSIONAL.
DANGER
Do not use an open flame to check for gas
leaks. Be sure there are no sparks or open
flames in the area while you check for gas
leaks. This will result in a fire or explosion
which can cause serious bodily injury or
death, and damage to property.
Wet the fitting with a soap and water solution. Any bubbles
that form or grow indicate a leak. If bubbles occur shut off
gas, tighten the fitting, and retest.
WARNING: If a leak persists after tightening the
fitting, turn gas off at the supply. DO NOT OPERATE
YOUR BARBECUE. Contact Weber-Stephen Customer
Service.

Recommended concrete pad requirements
We recommend a pad a minimum of 40 inches left to right,
20 inches front to back and 4 inches deep (1.85 cubic feet).
Figure 4.
Note - Cubic feet is determined by multiplying length times
width times depth and dividing by 1728.
20”

40”
Figure 4
If you use a concrete bag mix, use the mix for maximum
strength. An average 80 pound bag of concrete mix will
make approximately 2/3 of a cubic foot of concrete.
Note - Follow the concrete bag mix, manufacturers
recommendations concerning pad preparation, gravel,
sand, etc. Figure 5.
