Napoleon Ultra Chef U405 Manuel D'instructions page 5

Natural Gas Hook-Up: This natural gas grill is supplied with a 10ft (3m) supply hose (complete with a quick
disconnect) designed for natural gas and certified for outdoor 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 flex tube as illustrated in the Natural Gas Hose Attachment diagram. Tighten
using two wrenches. (Do not use thread sealer/pipe dope.) These connections must be made by a licensed gas
installer. Leak test all joints prior to using the gas grill.
IMPORTANT!
Ensure that the hose is routed around the front side of the cart leg to maintain proper
clearance to the underside of the unit.
Non-Side Burner Units: Connect the flared end of the hose to the fitting on the end of the manifold tube.
Wrench tighten. (Do not use thread sealer/pipe dope.)
Side Burner Units: Connect the 20 inch hose from the manifold, to the side burner as illustrated in the Natural
Gas Hose Attachment diagram. Connect the supply hose to the flare connection, which faces down from the
side burner. Tighten all connections using two wrenches. (Do not use thread sealer/pipe dope.)
WARNING!
• The installation must be performed by a licensed gas fitter, and all connections must be leak tested before
operating the grill.
• Do not route hose underneath drip pan.
• Do not route hose between space in bottom shelf 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
this manual.
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 recommended
by the 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.
