36" GAS COOKTOP WITH SEALED(SPILL-PROOF) BURNERSIMPORTANT SAFETY NOTICE: This information is intended foruse by persons possessing adequate backgrounds of electrical, electron-ic and mechanical experience. Any attempt to repair a major appliancemay result in personal injury and property damage. The manufacturer orseller cannot be responsiblefor the interpretation of this information, nor can it assumeany liability in connection with kits use.DISCONNECT POWER BEFORE SERVICINGIMPORTANT: Reconnect all grounding devices. All parts of this appliance ca-pable of conducting electrical current are grounded. If grounding wires, screws,straps, slips, nuts or washers used to complete a path to ground are removedfor service, they must be returned to their original position and properly fas-tened.GAS SUPPLY SHUT-OFF VALVE:Certain models of the cooktop are equipped with a gas shut-off valve. This valvemay be turned to the off position by rotating the shut-off valve knob, mounted in the con-trol panel of the maintop. This shut-off valve is NOT meant to replace the main cooktopshut-off valve mounted downstream of the gas regulator.IGNITION SYSTEM:The Ignition System consists of 4 spark switches (1 on each valve), 4 spark electrodes(1 on each burner) and a spark module. The burner control knob must be turned to theLITE position to light the burner and out of the LITE position to stop the sparking after theburner has ignited. All 4 electrodes will spark when any burner control knob is in the LITEposition.SPARK MODULE ACCESS:Access to the spark module varies depending upon the model number of the product.Please check the name and number plate to identify the model number prior to anydisassembly.• Make sure that power is disconnected before servicing.• Remove all control knobs.• Remove all burner caps.For all cooktops with glass maintop:• Remove the screws securing the burner bases. Use a number 15 torx bit forthis removal.• Lift the burner bases up from the glass maintop and remove the spark ignition wirefrom each burner electrode.• Lift the cooktop from the burner box bottom. The spark module is mounted in theburner box bottom.Testing flame stability:Test 1 – Turn the knob from “HI” to “LOW” quickly. If the “LOW” flame goes out, increasethe flame size and test again.Test 2 – With the burner on the “LOW” setting, open and close the cabinet door under thecooktop. If the flame is extinguished by the air currents created by the door movement,increase the flame height and test again.Flame recheck:After the adjustment is made, turn all burners off. Ignite each burner individually. Observethe flame at the “HI” position. Rotate the valve to the “LO” position and be sure that theflame size decreases as the valve is rotated counterclockwise.CONVERSION TO L.P./PROPANE GAS:The cooktop is shipped with a convertible regulator and a set of L.P/Propane gas orifices.1. CONVERT THE REGULATOR: Remove the spring retainer cap from the regulator body.Remove the plastic spring retainer from the center of the cap. Turn plastic springretainer upside down and re-install in cap.2. INSTALL THE L.P./PROPANE ORIFICES: Remove the electrodefrom the burner base. Remove the burner base using a No. 15 "torx" typebit. Using a 7mm nut driver, remove the natural gas orifice from each burner. Installthe L.P./Propane orifices supplied with the cooktop.*Note: The 18,000 BTU burner has two orifices, one main orifice and one simmerorifice. Both must be replaced in converting to LP/propane gas.IMPORTANT: Save the orifices removed from the appliance for future use. To convertback to natural gas, reverse the previous steps.* Use the Burner/Orifice specification chart to determine proper locationof orifices.LOW FLAME (SIMMER) ADJUSTMENTS:To adjust the simmer setting on all burners, except models that have an 18,000 BTU rightfront burner, perform the following:The top burner valves have low flame adjustment screws in the control valve body. Aflashlight may be required to locate the screw. A thin, flat blade (approximately 3/32"across) screwdriver is needed to access the screw.For cooktops with 18,000 BTU right front burner:• Remove right rear, left front and left rear burner bases by lifting from maintop.• Pull burner electrode up from maintop and remove spark ignition wire.• Remove three screws (from each burner) that hold the maintop to the burner spider. Anumber 15 torx bit is required.• Remove burner head from right front burner by pulling straight up from burner base.(Note: this is a snug fit, so pull straight up).• Remove two screws that secure the burner base to the burner inlet.• Remove the burner base from the maintop. The maintop may now be removed, expos-ing the spark module.For cooktops with 12,000 or 9,500 BTU right front burner:• Remove the burner bases by lifting from maintop.• Pull burner electrode up from maintop and remove spark ignition wire.• Remove three screws (from each burner) that hold the maintop to the burner spider. Anumber 15 torx bit is required.• Remove the maintop, exposing the spark module.To adjust the simmer setting on the burner:• Light 2 other burners and set the knob to a Medium to Hi setting.• Light the burner to be adjusted and turn the knob to “LOW”.• Remove knob.• Insert screwdriver through access hole in the valve switch.Engage adjustment screw in valve.• Turn the adjustment screw until the flame reaches thedesired size.Note: Some models may contain a silicone shield which covers thevalve switch and access hole. A flashlight may be required to locatethe access hole. To access the valve adjusting screw, push thescrewdriver through this shield. After adjustment, reseat the shieldaround the switch hub with your fingers, after withdrawing thescrewdriver.• Perform a flame stability test.• For the right front burner, if 18,000 BTU, the simmer screw is accessed through theburner valve shaft. Use a small flat-head screwdriver (4mm or 5/32" tip size, 60mmlong) to make the necessary adjustments.FOAM GASKET ON BURNER BOX(Non-Glass Models only)There is a foam gasket (seal) between the cooktop and the burner box. This gasket muststay in place to ensure proper airflow to the burners.CAUTION:1. When replacing burner bases on glass top models, do not tighten screws beyond 10in. lbs. torque.2. When replacing the burner base on the 18,000 BTU burner, make sure you do nottighten the base too tightly to the burner inlet. Over tightening will cause stripping ofthe screw.3. Cooktops: Before removing glass maintop, inspect the installation from belowto be sure cooktop is resting on the burner box top mounting flange and not theglass maintop.4. The rubber seal must be re-installed to prevent spillovers from seeping into theburner box bottom.ORIFICE SPUDLOCATED THRUTHIS OPENINGORIFICE SPUDLOCATED THRUTHIS OPENINGORIFICE SPUDLOCATED THRUTHIS OPENINGCapHeadBaseRemoveThisAssemblyCapHeadBaseCapHeadBaseCHANGING COOKTOP BURNER ORIFICESLocate the L.P./Propane orifices.
