INSTALLATION HIGHLIGHTS GAS SUPPLY REQUIREMENTS 2. WARNING 3. Explosion Hazard Use a new AGA approved gas supply line. Install a shutoff valve. Securely tighten all gas connections. If connected to LP gas, have a qualified person make sure gas pressure does not exceed 14" water column. Examples of a qualified person includes licensed heating personnel, authorized gas company personnel, and authorized service personnel. Failure to do so can result in death, explosion, or fire. 4.
6. The supply line shall be equipped with an approved shutoff valve. This valve should be located in the same room as the cooktop and should be in a location that allows ease of opening and closing. Do not block access to the shutoff valve. The valve is for turning on or shutting off gas to the appliance. 8. NATURAL GAS Set pressure: 4 inches (10.2 cm). Supply pressure: 7-14 inches (17.8 cm to 35.5 cm) maximum. Shutoff Valve (open) To Cooktop L.P. GAS Minimum pressure: 10 inches (25.4 cm).
ELECTRICAL REQUIREMENTS Recommended Ground Method WARNING For your personal safety, this cooktop must be grounded. This cooktop is equipped with a 3prong ground plug. To minimize possible shock hazard, the cord must be plugged into a mating 3-prong ground-type outlet, grounded in accordance with the National Electrical Code ANSI/NFPA 70 latest edition*, or Canadian Electrical Code (CSA) A**, and local codes and ordinances.
INSTALLATION 1. 5. Glass Cooktops Only: Remove the foam strip from the literature package and apply the strip around the bottom edge of the glass maintop so it is flush with the edges. Burner Box Install the 2-1/2" (6.4 cm) clamping screws into the brackets and tighten them so that they are firmly against the underside of the countertop. DO NOT overtighten the screws. Burner Box Glass Maintop Countertop Foam Strip 2-1/2" (6.4 cm) Clamping Screw Glass Maintop 2.
IMPORTANT: In the next step, you will need to: 7. • Determine the fittings that are required to hook up the gas supply to the pressure regulator. • Make sure that all of the connections are wrench-tightened and are not overtightened (you could crack the regulator and cause a gas leak). Do not allow the regulator to turn on the pipe when you tighten the fittings. • Use pipe-joint compound that is made for use with Natural and L.P. gas.
CONVERTING THE COOKTOP FOR USE WITH L.P. GAS NOTE: Refer to Conversion Kit #3192261 for SCS, GLT, KGCT, KGCS Model Series L.P. Gas Conversion Instructions. Parts provided with this Conversion Kit: • Orifice/Spud Package - #3192198 • Conversion Instructions - #3192260 • Conversion Label - #3192259 Gas conversions from Natural gas to L.P. gas must be done by a qualified installer. Caution; Before proceeding with conversion, shut off the gas supply to the appliance prior to disconnecting the electrical power.
L.P. GAS 3. Minimum pressure: 10 inches (25.4 cm). Supply pressure: 14 inches (35.5 cm). Testing below 1/2 psi (3.5 kPa) 14 inches (35.6 cm) W.C. (gauge) or lower The cooktop 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 l/2 psig (3.5 kPa). 4. Remove burner cap. Remove two screws in the burner base and remove burner base.
5. 6. Electronic Ignition System— Initial Lighting Use a nut driver (7 mm) to remove the existing orifice and replace it with an LP orifice. Note: A small amount of tape inside the nut driver will help hold the orifice in the nut driver. Replace burner base and tighten the two screws. Cooktop burners use electronic ignitors in place of standing pilots. When the cooktop control knob is pushed in and turned to the "LITE" position, the system creates a spark to light the burner.
decreased by turning the screw. Adjust the flame until you can quickly turn the knob from “LITE” to the lowest position without extinguishing the flame. The flame should be as small as possible without going out. 10. Push in and turn each control knob from the “LITE” to the “LO” setting. The low flame should be at a minimum steady blue flame. If flame needs to be adjusted, turn the control to the “LO” setting, and remove the control knob. Insert a small flat-blade screwdriver into the valve stem.

PRODUCT OPERATION ELECTRONIC IGNITION SYSTEM Refer to Figure 3-1 for the following sequence. SEALED BURNER When a main burner control knob q is turned to the “lite” position, the gas valve r opens, and gas flows through the pressure regulator s into the manifold t through the open valve. As gas passes through the valve and its orifice, it is directed into the venturi u, where it mixes with primary air to create the proper mixture necessary for combustion.

COMPONENT ACCESS COMPONENT LOCATIONS This section instructs you on how to service each component inside the built-in cooktops. The components and their locations are shown below. NOTE: The KitchenAid Model KGCS166G/ KGCT366G cooktop is shown below, however, the other built-in cooktop components are identical, and are serviced in the same manner.
REMOVING THE MAINTOP 1. WARNING Turn off the gas supply and electrical power to the cooktop. Remove the grates and burner caps. 2. Electrical Shock Hazard Refer to Figure 4-1 for the following steps. Disconnect from electrical and gas supplies before servicing unit. 3. 4. Failure to do so could result in death, electrical shock, or explosion. CAUTION: When you work on the cooktop, be careful when handling the sheet metal parts.
REMOVING A VENTURI & SPARK IGNITOR Refer to Figure 4-2 for the following steps. WARNING 3. Remove the mounting screw from the front of the bracket that contains the venturi or spark ignitor you wish to service. Remove the tubing and ignitor wires from each venturi and spark ignitor on the bracket. Lift the front of the mounting bracket, remove the mounting screw from the venturi, and remove the venturi. NOTE: You may have to completely remove the bracket to remove the venturi.
REMOVING A SPARK MODULE & POWER CORD 4. WARNING Electrical Shock Hazard Disconnect from electrical and gas supplies before servicing unit. Failure to do so could result in death, electrical shock, or explosion. CAUTION: When you work on the cooktop, be careful when handling the sheet metal parts. Sharp edges may be present, and you can cut yourself if you are not careful. 1. 2. To remove the power cord: a) Disconnect the lead from the spark module terminal, and from the ignitor switch wire connector.
REMOVING AN IGNITOR SWITCH & A GAS VALVE NOTE: If one ignitor switch is defective, all of the switches must be replaced as an assembly. WARNING 4. Electrical Shock Hazard Disconnect from electrical and gas supplies before servicing unit. Failure to do so could result in death, electrical shock, or explosion. CAUTION: When you work on the cooktop, be careful when handling the sheet metal parts. Sharp edges may be present, and you can cut yourself if you are not careful. 1. 2. 5.
REMOVING THE GAS MANIFOLD 4. WARNING 5. Electrical Shock Hazard Disconnect from electrical and gas supplies before servicing unit. 6. 7. Failure to do so could result in death, electrical shock, or explosion. CAUTION: When you work on the cooktop, be careful when handling the sheet metal parts. Sharp edges may be present, and you can cut yourself if you are not careful. 1. 2. 3. 8. 9. Turn off the gas supply and electrical power to the cooktop.
COMPONENT TESTING THE IGNITOR SWITCHES Refer to Figure 5-1 on the next page. 3. Disconnect the black ignitor switch wire from the line cord connector and the white wire from the spark module terminal. 4. Connect the leads of an ohmmeter to the ends of the spark module wires. 5. Set the ohmmeter to the R x 1 scale. 6. Press and turn one of the gas valve knobs to the LITE position. At that point, the switch should close, and the meter should indicate continuity. 7.

TECH TIPS SURFACE BURNERS & GRATES The locator pin on the grates must be positioned in the burner cap hole to hold the grate in place (see Figure 8-1). The left and right grates contain grooves. The grooves must always face inward toward the control knobs to hold the grates in place. The middle grate must be placed in position first followed by the left and right grates (see Figure 8-2). IMPORTANT: The cooktop has been factoryset for use with Natural gas. An L.P.
CLEANING THE SURFACE BURNERS Refer to Figure 8-3. The burner caps should be routinely removed and cleaned. Keeping the burner caps clean prevents improper ignition and an uneven flame. For the proper flow of gas and ignition of the burner, DO NOT ALLOW SPILLS, FOOD, CLEANING AGENTS, OR ANY OTHER MATERIAL TO ENTER THE GAS TUBE (VENTURI) OPENING. Gas must flow freely through the gas tube opening for the burner to light properly.
