STEP 3
Gas and Electrical Supply Requirements
The correct voltage, frequency and amperage must be supplied to the appliance from an isolated, grounded circuit which is protected by a
properly sized circuit breaker or time-delay fuse.
The cooktop must be connected to the power supply with copper wire only. The use of aluminum wire may result in unsatisfactory connections.
Flexible armored or non-metallic, sheathed copper cable (with a grounding wire) should be used to supply electrical power to the junction
box or receptacle.
For the SGM304, SGM364, SGM365, SGM466 and SGM464GG the factory-equipped, three-prong grounding plug must be inserted into a
mating grounding-type receptacle in accordance with National Electric Code and applicable state, municipal and local codes.
Be certain to locate the junction box or electrical outlet so the electrical supply may be easily disconnected in the event that service becomes
necessary. Also, provide extra slack in the cable to allow the cooktop to be removed for servicing.
IMPORTANT:
1. If the electrical supply circuit does not have a grounding-type receptacle, it is the responsibility
of the customer to have the existing receptacle changed by an electrician to a properly grounded
receptacle.
2. The power supply must be properly polarized. Reverse polarity will result in continuous sparking
of the electrodes, even after flame ignition. If the power supply is not properly polarized, it is the
responsibility of the customer to have the polarity corrected.
3. If there is any doubt as to whether the wall receptacle is properly grounded or polarized, have it
checked by a qualified electrician prior to installing the cooktop.
4. Do not plug the cooktop into Ground Fault Circuit Interrupter (GFCI) receptacles. The cooktop
spark ignition module can cause a GFCI to trip.
STEP 4
Installing the Cooktop
Place and center the cooktop within the cutout. Secure the cooktop to the countertop utilizing the two (2) hold-down brackets provided. Do
not over-tighten the screws.
IMPORTANT:
Do not use a hardening compound or caulking to permanently seal the cooktop into place, as the
unit must be readily removable for service. If such a hardening compound is used, removal of the
unit will be at the customerʼs expense.
STEP 5
Connecting the Gas
WARNINGS:
1. The maximum gas supply pressure to the regulator must not exceed 1/2 pound per square inch.
2. Verify that the proper gas supply has been provided according to Step 3.
3. Do not apply excessive pressure when tightening connections and fittings.
4. Do not use plumber's putty or Teflon tape on gas compression connections. It can defeat the
proper sealing of these fittings. Use plumber's putty or Teflon tape only on pipe thread fittings.
5. Turn all cooktop control valves to the “OFF” position, then turn on the gas supply. Check all
supply lines and connections for leaks using a soap and water solution. Do not use a flame
to check for leaks. After verifying that there are no gas leaks, turn off the gas supply to the
cooktop by turning the gas shut-off valve to the off position. Leak testing of the appliance shall
be conducted according to the manufacturerʼs instructions.
6. For LP gas installations, the LP gas tank must have its own high-pressure regulator. This is in
addition to the pressure regulator supplied with the cooktop.

Page 6
Page 7
STEP 5
Connecting the Gas
Attach the gas pressure regulator (included with the cooktop) to cooktop pipe nipple inlet. For tight installations, the regulator may be installed
upstream from the pipe nipple, anywhere between the shut-off valve and the cooktop.
Install a gas shut-off valve (not included with the cooktop) in the main gas supply line in an accessible location near the cooktop. Complete
connection of the gas supply to the cooktop by installing 1/2 inch flexible gas line (not included with the cooktop) between the pressure
regulator and the shut-off valve.
IMPORTANT:
To prevent damage to the gas pressure regulator, install the regulator only after the cooktop is
mounted in its permanent position. Ensure that the arrow on the regulator points in the direction
of the gas flow towards the cooktop.

corresponding burner ring. Place each grate onto the cooktop, being certain that the rubber feet are positioned in the locating dimples.
Grill Components
Remove the grill components from inside the main carton. Remove all of the packing materials from the Grill, U-burner, Heat Control Channels,
Grease Control Box and the Drip Pans.
Begin your set up by placing the Drip Pans inside on the bottom of the open grill burner box area, using the dimples to locate the Drip Pan.
Next, slip the open end of the U-burner onto the gas stub located in the front inside of the grill burner box, and insert the bracket on to opposite
end of the U-burner into the slot located on the Grease Control Box.
Proceed to install the Heat Control Channels, which sit on top of four pins at the inside front and back of the grease control box. Finally,
set the grill in place on the top of the cooktop.
WARNING:
Never attempt to operate the cooktop with any of the burner rings, burner caps, grates, or grill
components removed.

Electrical Connection
WARNINGS:
1. Ensure that the power supply is disconnected before proceeding.
2. Verify that the power supply matches the ratings found on the appliance data plate before
proceeding.
3. The complete appliance must be properly grounded at all times when electrical power is
applied.
4. Do not ground the appliance with the neutral (white) house supply wire. A separate ground
wire must be utilized.
5. If aluminum house supply wiring is utilized, splice the appliance copper wires to the aluminum
house wiring using special connectors designed and agency-certified for joining copper and
aluminum.
6. Follow the connector manufacturerʼs recommended procedure carefully. Improper connection
can result in a fire hazard!
SGM304, SGM364, SGM365, SGM466 and SGM464GG: Plug the three-prong plug from the appliance into the properly grounded and
polarized wall receptacle.
WARNINGS:
1. If the cooktop fails to operate properly, ensure that the electrical power supply and gas supply
are turned on and that all installation steps have been carefully followed. Call a qualified service
technician if the cooktop still does not operate properly.
2. The cooktop and shut-off valve must be disconnected from the gas supply piping during any
pressure testing exceeding 1/2 pound per square inch (3.5 kPA).
3. The cooktop must be isolated from the gas supply piping by closing the shut-off valve during any
pressure testing at or below 1/2 pound per square inch (3.5 kPA).
Before beginning the test procedure, ensure that the gas supply is turned off at the
shut-off valve, all cooktop control valves are in the “OFF” position, and all burner
rings, burner caps, and grates are properly positioned on the cooktop.
SGM Models
Rotate one knob at a time counterclockwise to the “HIGH” position. Verify that all
ignitors spark continuously, then return the knob to the “OFF” position. Repeat for all
knobs.
PGM Model
Rotate one knob at a time counterclockwise to the “HIGH” position. Verify that
associated burner igniter sparks, then return the knob to the “OFF” position. Repeat
for all knobs.
Turn on the main gas supply to the cooktop by opening the gas shut-off valve.
Test each burner separately by pressing and turning one control knob at a time
counterclockwise to the “HIGH” position. On the SGM models, all ignitors will spark
simultaneously, but only the burner with gas flowing to it will ignite. On the PGM model, only the selected burner will spark. (It will take
approximately four seconds for ignition to occur, at which time all ignitors will stop sparking. If ignition does not occur within four seconds, turn
off the knob, wait for at least two minutes to allow any gas to dissipate, then repeat this ignition test.) The control knob can then be rotated
counterclockwise from “HIGH” to “LOW” to adjust the flame height progressively. Repeat the ignition test for all burners.
When installed properly, the flame will be steady and quiet. It will also have a sharp, blue inner cone that will vary in length proportional to
the burner size. Flame adjustment will not be necessary.
