Important Information about Natural GAS

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.

•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:

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.

•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.
