Natural Gas Conversion
Conversion must be made by a qualified gas technician. The
qualified Natural gas technician shall provide the Natural gas
supply to the selected grill location in accordance with the
National Fuel Gas Code ANSI Z223.1/NFPA 54 - latest edition,
and local codes. For conversion to Natural gas, the Natural Gas
Conversion Kit supplied with the grill (on some models) or the
Natural Gas Conversion Kit Part Number 710-0003 must be
used. See "Assistance" section for information on ordering.
IMPORTANT: The gas installation must conform with local
codes, or in the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 - latest edition.
Follow instructions for converting to Natural gas in the "Gas
Conversions" section of this manual or the instructions supplied
with Natural Gas Conversion Kit Part Number 710-0003.
The gas supply line shall be equipped with an approved shutoff
valve. This valve should be located in the same area as the grill
and should be in a location that allows ease of opening and
closing. Do not block access to the shutoff valve. The valve is for
turning on or shutting off gas to the grill.
