• To eliminate the risk of burns or fire by reaching over
heated surface units, cabinet storage space located
above the surface units should be avoided. If cabinet
storage is to be provided, the risk can be reduced by
installing a hood that projects horizontally a minimum
of 5 inches beyond the bottom of the cabinet.
• Verify that cabinets above the cooktop are a maximum
of 13" (330 mm) deep.

Preparation
Electrical Requirements
This appliances requires a 60 Hz, 15 Amp, 120 VAC
connection. Plan the installation so that the power
connection is accessible from the front of the cabinet.
Gas Requirements
Supply Pressure:
•Natural Gas - 7 inches water column (14.9 Millibars)
minimum.
•Propane Gas -11 inches water column (27.4 Millibars)
minimum.
The propane gas tank must be equipped with its own high
pressure regulator in addition to the pressure regulator
supplied with this unit. The cooktop is shipped from the
factory for use with natural gas. For use with LP conversion
kit – Model SNLPKITF, must be purchased separately. A
qualified technician or installer must do the conversion.
Cabinet Requirements
Dimension requirements in Figures 1 and 2 are for
combustible surfaces. When the surface is protected by a
material listed by UL as a Floor Protector and Wall Shield
covered with not less than No. 28 MSG sheet metal 0.015
inch (0.38mm) stainless steel, 0.024 inch (0.6mm)
aluminum or copper, it is considered noncombustible and
some dimensions may be reduced. For a noncombustible
surface over the cooktop, the minimum clearance is 24"
(61cm) rather than 30" (76cm).
• Instructions are based on standard American cabinets
36" high (91cm) x 24" deep (61cm) with a 25" (63cm)
countertop.
• Provide approximately a 10 square inch opening
(65cm2) in the toe kick area or other cabinet area for
adequate air inlet to the cabinet if installed with a
downdraft.
• The maximum depth of cabinet installed above cooktop
is 13” (33cm).

Prepare the Countertop
Cut out the countertop per the dimensions shown in
“Cabinet Requirements” on page 3.
Some solid surface materials, such as Surell™ and
Corian®, require different cutting methods. Consult with the
solid surface manufacturer for the correct cutting method
needed. Apply heat reflective tape such as Scotch
Aluminum Foil Tape #425 or #427 (not included) around
the cutout so that it folds over on the top and sides. Do not
wrap the tape underneath the cooktop. Be sure the tape
extends beyond the outermost flange of the cooktop. All
corners should be covered with tape.
Seal the Cooktop with Foam Tape
Apply the self adhesive foam tape in one continuous
rectangle directly to the counter around the perimeter ofthe
cutout as shown by the dotted line in Figure 4: “Counter
Cutout – Foam Tape Placement”. Leave 1/4” (6.35mm) gap
between the foam tape and the edge of the cutout.
Install the Cooktop
Insert cooktop into the cutout. Attach clamps of the hold-
down brackets packaged with the cooktop to the rough-in
box. Use the washer and screws provided.
Adjust hold-down brackets to desired position and tighten
screws to rough-in box. Insert adjusting screw into clamp
and secure cooktop to countertop.
NOTE:
For solid surface material installations: Insert a wooden
block between the end of the screw and the bottom of the
countertop. Do not overtighten adjusting screw. Trim
excess aluminum tape around cooktop flange.
Connect Gas Supply
The gas inlet to the unit is located at the right rear of rough-
in box.
Install the pressure regulator (supplied with unit) to
manifold pipe using Teflon tape on threads of manifold
pipe. Turn to hand tighten plus 1/4 turn, not exceeding 1
turn for alignment. To prevent possible damage to the gas
pressure regulator, install it after the rough-in box is in its
permanent position. When the regulator is securely

installed on the manifold pipe, the conversion nut will be
easily accessible.
CAUTION:
Do not attempt any adjustment of the pressure
regulator, except conversion to propane.
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. Do not use a flame of any sort.
1. Turn on gas.
2. Apply a non-corrosive leak detection fluid to all joints
and fittings in the gas connection between the shut-off
valve and the range. Include gas fittings and joints in
the range 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 shut-
off valve. When leak check is complete (no bubbles
appear), test is complete.
5. Wipe off all 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 psig (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 5-foot (1.5 m) supply cord to wall
receptacle, make certain that gas shutoff valve and all
burner controls are in OFF position.
Burner Cap Placement
WARNING:
To prevent flare-ups, do not use the cooktop
without all burner caps and all burner grates
properly positioned.
WARNING:
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.
• Burners do not ignite.
• Burner flames light unevenly.
• Burner emits gas odor.
Placing Burner Caps
Each cap has a letter (B, D, or F) cast in the underside of
the cap that corresponds to a letter (B, D, or F) cast in the
burner base that is attached to the appliance.
• After electrical connection is complete, place each
burner cap on its correct burner base per its
corresponding letter designation.

• 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.
Checking Burner Cap Placement
• Check to make sure there is no gap between the
burner cap and burner base. See figure “Burner Cap
Placement” to see the correct and incorrect
placements of the burner cap.
• You may gently try to move the burner cap from side to
side to check if it is properly placed. If properly placed,
the cap will click from side to side as the prongs hit the
groove ridge.

Final Check
Check operation of electric igniters. Check flame
characteristics. Flame should be blue with no yellow tip.
Service
Before Calling Service
If the ignitors do not spark or the “on” indicator lights do not
glow, check the power source to see if a fuse has blown or
if the circuit breaker has tripped.
Refer to the Warranty in the Use and Care Manual. See
Use and Care manual for troubleshooting information.
Product Data Plate
The data plate shows the model and FD (product's unique
identifier for customer service) number of your cooktop. It
is located on the underside of the rough-in box, underneath
the cooktop. Keep your invoice or escrow papers for warranty validation
if service is needed.
Figure 11: Checking Flame Characteristics
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or
mostly yellow, verify that the regulator is set for the
correct fuel. After adjustment, retest.
Some yellow streaking is normal during the initial start-
up. Allow unit to operate 4-5 minutes and re-evaluate
before making adjustments.
