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 tin-lined copper or an AGA-approved alternate. Operating pressure of the grill is 7" water column pressure. This should be verified after the installation is complete. Comparable sized black iron pipe is also acceptable for natural gas lines.

GAS LEAK 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.

CAUTION: The appliance and its individual shut off 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).

CAUTION: The appliance must be isolated from the gas supply piping system by closing its individual manual shut off 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).

WARNING: Never use an open flame when testing for gas leaks! Use of an open flame may result in serious bodily injury or death, or in a fire or an explosion causing damage to property.
