Connect the gas supply line to the unit pressure regulator using a 1/2” flex gas line connector between manual shut-off valve and pressure regulator. Always use a new flex line.

Check supply line connections for leaks using a soap solution or non-corrosive leak detection fluid. Do not use a flame of any sort.

1.Turn on gas.

2.Apply a soap solution or non-corrosive leak detection fluid to all joints and fittings in the gas connection between the shut-off valve and the cooktop. Include gas fittings and joints in the cooktop if connections may have been disturbed during installation. Bubbles appearing around fittings and connections indicate a leak.

3.If a leak appears, turn off supply line gas shut-off valve and tighten connections.

4.Retest for leaks by turning on the supply line gas shutoff valve. When leak check is complete (no bubbles appear), test is complete.

5.Wipe off all soap solution or detection fluid residue.

Important Notes for Gas Connection:

The appliance and its individual gas 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 psi (3.5kPa).

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 psi (3.5kPa).

Connect Electrical Supply

Before connecting the 5-foot (1.5m) supply cord to a wall receptacle, make certain that gas shut-off valve and all burner controls are in OFF position.

Burner Cap and Burner Base Placement

9WARNING

To prevent flare-ups, do not use the cooktop without all burner caps and all burner grates properly positioned.

9WARNING

To prevent burns, do not touch burner caps or grates while hot. Turn the cooktop off and allow the burners to cool.

The burner caps must be properly placed for the cooktop to function properly. If the burner cap is not properly placed, one or more of the following problems may occur:

Burner flames are too high.

Flames shoot out of burners.

Stainless steel discolors.

Burners do not ignite.

Burner flames light unevenly.

Burner emits gas odor.

10

Burner Cap and Burner Base Placement

After electrical connection is complete, place each burner base on the corresponding location on the cooktop. One of the three bars on the burner base should line up with the notch and prevent the base from rotating. The small hole or cutout near the edge should also line up with the igniter. Pay special attention to avoid damaging the igniter during installation of the base. See Illustration below.

Once each base is located and resting evenly, place each burner cap on its correct burner base. See Illustration.

Place burner cap gently on top of base so that the prongs of the burner base fit snugly into the groove of the burner cap.

If the maintop is removed by a certified installer (for example to check electrical or piping connection) the panhead screws that were removed must be reinstalled to ensure proper functionality of burners.
