36" GAS COOKTOP WITH SEALED
(SPILL-PROOF) BURNERS
IMPORTANT SAFETY NOTICE: This information is intended for
use by persons possessing adequate backgrounds of electrical, electron-
ic and mechanical experience. Any attempt to repair a major appliance
may result in personal injury and property damage. The manufacturer or
seller cannot be responsible
for the interpretation of this information, nor can it assume
any liability in connection with kits use.
DISCONNECT POWER BEFORE SERVICING
IMPORTANT:
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 removed
for 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 valve
may 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 cooktop
shut-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 the
LITE position to light the burner and out of the LITE position to stop the sparking after the
burner has ignited. All 4 electrodes will spark when any burner control knob is in the LITE
position.
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 any
disassembly.
•
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 for
this removal.
•
Lift the burner bases up from the glass maintop and remove the spark ignition wire
from each burner electrode.
•
Lift the cooktop from the burner box bottom. The spark module is mounted in the
burner box bottom.
Testing flame stability:
Test 1 –
Turn the knob from “HI” to “LOW” quickly. If the “LOW” flame goes out, increase
the flame size and test again.
Test 2 –
With the burner on the “LOW” setting, open and close the cabinet door under the
cooktop. 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. Observe
the flame at the “HI” position. Rotate the valve to the “LO” position and be sure that the
flame 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 spring
retainer upside down and re-install in cap.
2.
INSTALL THE L.P./PROPANE ORIFICES:
Remove the electrode
from the burner base. Remove the burner base using a No. 15 "torx" type
bit. Using a 7mm nut driver, remove the natural gas orifice from each burner. Install
the L.P./Propane orifices supplied with the cooktop.*
Note: The 18,000 BTU burner has two orifices, one main orifice and one simmer
orifice. Both must be replaced in converting to LP/propane gas.
IMPORTANT:
Save the orifices removed from the appliance for future use. To convert
back to natural gas, reverse the previous steps.
*
Use the Burner/Orifice specification chart to determine proper location
of orifices.
LOW FLAME (SIMMER) ADJUSTMENTS:
To adjust the simmer setting on all burners, except models that have an 18,000 BTU right
front burner, perform the following:
The top burner valves have low flame adjustment screws in the control valve body. A
flashlight 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. A
number 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. A
number 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 the
desired size.
Note:
Some models may contain a silicone shield which covers the
valve switch and access hole. A flashlight may be required to locate
the access hole. To access the valve adjusting screw, push the
screwdriver through this shield. After adjustment,
reseat the shield
around the switch hub with your fingers
, after withdrawing the
screwdriver.
•
Perform a flame stability test.
•
For the right front burner, if 18,000 BTU, the simmer screw is accessed through the
burner valve shaft. Use a small flat-head screwdriver (4mm or 5/32" tip size, 60mm
long) 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 must
stay in place to ensure proper airflow to the burners.
CAUTION:
1.
When replacing burner bases on glass top models, do not tighten screws beyond 10
in. lbs. torque.
2.
When replacing the burner base on the 18,000 BTU burner, make sure you do not
tighten the base too tightly to the burner inlet. Over tightening will cause stripping of
the screw.
3. Cooktops:
Before removing glass maintop, inspect the installation from below
to be sure cooktop is resting on the burner box top mounting flange and
not
the
glass maintop.
4.
The rubber seal must be re-installed to prevent spillovers from seeping into the
burner box bottom.

CHANGING COOKTOP BURNER ORIFICES
Locate the L.P./Propane orifices. Remove the orifices from the bracket.
The L.P./Propane orifices are shipped in the literature package. They will
have a digit number and the letter “L” on one side.
(Important: Save the
orifices removed from the appliance for future use.)
Each orifice will also show a series of engraved marks, (I, II, III, X, or
none), located on the top. These marks denote the precise location of
each orifice to the cooktop burner.
The 18,000 BTU/HR burner has 2
orifices with markings located on
the side only. See rating plate on
bottom of cooktop.)

(on some models)
NOTE:
The main orifice is located
low in the center of the burner while
the simmer orifice is located higher
behind the center of the burner.
