IMPORTANT INFORMATION ABOUT NATURAL GAS

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.

•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.

STORAGE AND/OR NONUSE

For grills that have been stored or left unused for a while, it is important to follow these guidelines:

•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.

•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 control panel and the slide-out grease tray 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.”)

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).

•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.

mWARNING: 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.

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.
