37Installation InstructionsPRoVIDE ADEqUATE GAS SUPPLyThis range is designed for an operating manifoldpressure of 4” or 5” water column (w.C.) on natural gas(see rating label on product) or 10” w.C. on LP gas.This range comes from the factory set for use on naturalgas, but it is convertible for use on LP gas. If you decide touse this range on LP gas, conversion must be made by aqualified LP installer before attempting to operate therange.For proper operation, the inlet pressure to the regulatorshould be at least 1” W.C. above the operating manifoldpressure but must not exceed 14” W.C.The pressure regulator located at the inlet of the rangemanifold must remain in the supply line regardless ofwhether natural or LP gas is being used. When checking forproper operation of the regulator, the inlet pressure must beat least 1” greater than the operating manifold pressure.A flexible metal appliance connector used to connect therange to the gas supply line should have an I.D. of ½” andbe 5 feet in length for ease of installation. In Canada,flexible connectors must be single wall metal connectors nolonger than 6 feet in length.1CoNNECT THE RANGE To GASShut off the main gas supply valve before disconnectingthe old range and leave it off until the new hookup hasbeen completed. Don’t forget to relight the pilot on othergas appliances when you turn the gas back on.Because hard piping restricts movement of the range,the use of a CSA International-certified flexible metalappliance connector is recommended unless local codesrequire a hard-piped connection.Never use an old connector when installing a new range.If the hard piping method is used, you must carefully alignthe pipe; the range cannot be moved after the connectionis made.To prevent gas leaks, put pipe-joint compound on, or wrappipe-thread tape with Teflon* around, all male (external)pipe threads.A. Install a manual gas line shut-off valve in the gas linein an easily accessed location outside of the range.Make sure everyone operating the range knows whereand how to shut off the gas supply to the range.B. Install male 1/2″ flare union adapter to the 1/2″ NPTinternal thread at inlet of regulator. Use a backup wrenchon the regulator fitting to avoid damage.B. When installing the range from the front, remove the 90°elbow for easier installation.C. Install male 1/2″ or 3/4″ flare union adapter to the NPTinternal thread of the manual shut-off valve, taking careto back up the shut-off valve to keep it from turning.D. Connect flexible metal appliance connector tothe adapter on the range. Position range to permitconnection at the shut-off valve.E. When all connections have been made, make sureall range controls are in the off position and turn onthe main gas supply valve. Use a liquid leak detectorat all joints and connections to check for leaks inthe system.When using test pressures greater than 1/2 psig topressure test the gas supply system of the residence,disconnect the range and individual shut-off valve fromthe gas supply piping. When using test pressures of 1/2psig or less to test the gas supply system, simply isolatethe range from the gas supply system by closing theindividual shut-off valve.*Teflon: Registered trademark of DuPont2wARNING: Do NoT USE A FLAMETo CHECK FoR GAS LEAKS.LoCATIoNDo not locate the range where it may be subject tostrong drafts. Any openings in the floor or wall behindthe range should be sealed. Make sure the openingsaround the base of the range that supply fresh air forcombustion and ventilation are not obstructed bycarpeting or woodwork.Your range, like many other household items, is heavy andcan settle into soft floor coverings such as cushioned vinylor carpeting. Use care when moving the range on this typeof flooring. It is recommended that the following simple andinexpensive instructions be followed to protect your floor.The range should be installed on a sheet of plywood(or similar material). When the floor covering ends atthe front of the range, the area that the range will reston should be built up with plywood to the same levelor higher than the floor covering.This will allow the range to be moved for cleaningor servicing. Also, make sure your floor covering willwithstand 180°F. (See the Installation Safety Instructionssection.)Make sure the wall coverings around your range canwithstand the heat generated (up to 200°F) by the range.(See the Installation Safety Instructions section.)
