CONNECTION Natural Gas Grills
Type of Gas
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. Your grill operates at 7” of water column pressure. If replacement of the hose becomes necessary, factory specified parts are required. See your local dealer.
For safety and design reasons, the conversion of a Ducane® grill from operation using Natural gas to operation using LP gas requires the change out of the entire gas supply system of the grill. If this becomes necessary, see your dealer for additional information.
What is Natural Gas?
Natural gas, often called methane, is a safe modern fuel. Natural gas is supplied by your local utility and should be readily available if your house is already heated with gas.
Portable Installation
Limited portability can be afforded to the grill head when mounted on the portable cart. All grill heads mounted on this portable cart and cabinet model grills so equipped can be moved about 10 feet away from the main gas supply. Ducane recommends moving the grill at least two (2) feet from the gas supply and any combustible surfaces. After the gas supply has been run and checked for leaks in accordance to the assembly instructions, you are ready to grill. To connect the hose to the gas supply, pull back the outer fitting, insert the hose fitting all of the way, and release the outer fitting. This process will produce a gas joint.
Follow special storage instructions located in the Helpful Hints section of this manual for proper care of your grill and its gas hose.
NATURAL GAS INSTALLER’S GUIDE
This guide is a recommendation for natural gas installations. It advises the installer as to the size tubing that is necessary on a natural gas installation depending on how far the grill is located from the house. All tubing should be anticorrosive
Distance | Pipe Size |
1 - 25 feet | 3/8" |
|
|
26 - 50 feet | 1/2" |
|
|
51- 100 feet | 2/3 of the run 3/4" down to 1/2" |
|
|
101 feet or more | 3/4" |

Gas Leaks Checks
Before operating your grill, check carefully to be certain that all connections are tight and there are no gas leaks. Never use a match or flame for leak detection. Use soapy water or testing solution. Brush the solution on to connection points and look closely for bubbles indicating escaping gas. If leaks are detected, shut off the main gas supply valve and securely retighten connections, then repeat the leak test.
