Gas Appliance Safety
WARNING:
If the information in this manual is not followed exactly, a
fire or explosion may result causing property damage,
)ersonal injury or death.
-- Do not store or use combustible materials,
gasoline or other flammable vapors and liquids
in the vicinity of this or any other appliance.
• The appliance 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 attest pressures equal to or less than ½
psi (3.5 kPa)
• The minimum supply pressure must be 1" water
column above the manifold pressure printed on the
data plate.
• The maximum supply pressure must not exceed 14.0
inches water column (34.9Millibars).
• For Massachusetts installations:
• Installation must be performed by a qualified or
licensed contractor, plumber or gas fitter qualified
or licensed by the state, province or region where
this appliance is being installed.
• Shut-off valve must be a "T" handle gas cock.
• Flexible gas connector must be new and not longer
than 36 inches.
Installer- show the owner where the gas shut-off valve
is located.
Propane Gas Installation
-- WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch.
• Do not use any phone in your building.
• Immediately call your gas supplier from a
neighbor's phone. Follow the gas supplier's
instructions.
• If you cannot reach your gas supplier, call
the fire department.
-- Installation and service must be performed by a
qualified installer, authorized service agency or
the gas supplier.
• Install a gas shutoff valve near the appliance. It must
be easily accessible in an emergency.
• Leak testing must be conducted by the installer
according to the instructions in this manual.
• The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing at pressures in excess of ½ psi
(3.5 kPa).
The propane gas tank must be equipped with its own
high pressure regulator. In addition, the regulator
supplied with this unit must also be used.
The appliance is shipped from the factory for use with
natural gas. It must be converted for use with propane.
A qualified technician or installer must do the
conversion using the Liquid Propane Conversion Kit
(NEZ1054).
Equipment and Usage Safety Requirements
The cooktop must be used in conjunction with a
suitable ventilation system.
Remove all tape and packaging before using the
appliance. Destroy the packaging after unpacking the
appliance. Never allow children to play with packaging
material.
Never modify or alter the construction of the appliance.
For example, do not remove panels, wire covers or
screws.
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

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 NEZ1054, must be purchased separately. A

box. Use the washer and screws provided.
Prepare the Countertop
Cut out the countertop per the dimensions shown in
"Cabinet Requirements" on page 3.
Some solid surface materials, such as Surell TM 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.

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).
Figure 7: Pressure Regulator
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.

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:

Check supply line connections for leaks using a soap
solution. Do not use a flame of any sort.

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.

If a leak appears, turn off supply line gas shut-off valve
and tighten connections.

• 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 (A, D, or F) cast in the underside of
the cap that corresponds to a letter (A, 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
correspondingletterdesignation.See figure "Burners
Caps" on page 7.
• 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.
Burner Base
Checking Burner Cap Placement
Check to make sure there is not gap between the
burner cap and burner base. See figure "Bumer Cap
Placement" on page 7 to see the correct and incorrect
placements of the burner cap.

Final Check
Check operation of electric igniters. Check flame
characteristics. Flame should be blue with no yellow tip.
Service
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.
Figure 11: Checking Flame Characteristics
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.
