Natural Gas Hook-Up: These connections must be made by a licensed gas fitter. This natural gas grill is sup-
plied with a gas supply hose (complete with a quick disconnect) designed for natural gas and certified for out-
door use. The gas grill is designed to operate at an inlet pressure of 7 inches water column. Piping and valves
upstream of the quick disconnect are not supplied. The installation must comply with CAN B149.1 Natural
Gas and Propane installation code in Canada, or to the National Fuel Gas Code, ANSI Z223.1 in the United
States. The gas supply pipe must be sufficiently sized to supply the BTU/h specified on the rating plate, based
on the length of the piping run. The quick disconnect must not be installed in an upward direction and a
readily accessible manual shut-off valve must be installed upstream of, and as close to, the quick disconnect
as is feasible. The flared end of the hose must be connected to the fitting on the end of the manifold tube
or flex tube (if applicable) as illustrated in the Natural Gas Hose Attachment diagram. Tighten using two
wrenches. (Do not use thread sealer/pipe dope.) Leak test all joints prior to using the gas grill.
WARNING!
• The installation must be performed by a licensed gas fitter, and all connections must be leak tested be-
fore operating the grill.
• Do not route hose underneath the drip pan.
• Do not route hose between bottom shelf space and back panel.
• Do not route hose over top of rear panel.
• Ensure all hose connections are tightened using two wrenches. Do not use Teflon tape or pipe dope on
any hose connection.
• Ensure the hose does not contact any high temperature surfaces or it may melt and leak causing a fire.
• Leak test all the connections using a soap and water solution as per the leak testing instructions found in
the manual.
• The outdoor cooking gas 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 0.5 psi (3.5
kPa).
• The outdoor cooking gas appliance must be isolated from the gas supply piping system by closing its indi-
vidual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures
equal to or less than 1/2 psi (3.5 kPa).
Leak Testing Instructions
WARNING!
A leak test must be performed annually and each time a cylinder is hooked up or if a part
of the gas system is replaced.
WARNING!
Never use an open flame to check for gas leaks. Be certain no sparks or open flames are
in the area while you check for leaks. Sparks or open flames will result in a fire or explosion, damage to
property, serious bodily injury, or death.
Leak testing: This must be done before initial use, annually, and whenever any gas components are replaced
or serviced. Do not smoke while performing this test, and remove all sources of ignition. See Leak Testing
Diagram for areas to check. Turn all burner controls to the off position. Turn gas supply valve on.
Brush a half-and-half solution of liquid soap and water onto all joints and connections of the regulator, hose,
manifolds and valves.
Bubbles will indicate a gas leak. Either tighten the loose joint or have the part replaced with one recommend-
ed by the Napoleon Customer Care department and have the grill inspected by a certified gas installer.
If the leak cannot be stopped, immediately shut off the gas supply, disconnect it, and have the grill inspected
by a certified gas installer or dealer. Do not use the grill until the leak has been corrected.
