Natural Gas Grills 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 specifi ed on the grill rating plates.
Your grill operates at 7" of water column pressure. If replacement of the hose becomes
necessary, factory specifi ed parts are required. See your local dealer.
For safety and design reasons, the conversion of a Ducane
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 fi tting, insert the hose fi tting all of the way, and release the outer fi tting. 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 verifi ed after the installation is complete. Comparable sized black iron
pipe is also acceptable for natural gas lines.

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 fl ame 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 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).
CAUTION: The 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).
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.
