MULTIPLE COOKTOP INSTALLATION
If the gas cooktop is to be used with any combination of
additional cooktops or modules with a filler strip, the
dimensions provided in the chart are derived by adding
11/4" (32) additional space for each additional unit, to give
you the total countertop cut-out width. Dimensions
include the filler strip available through your authorized
Wolf dealer. For local dealer information, visit the find a
showroom section of our website, wolfappliance.com.
Failure to locate the cooktop without the proper clear-
ances will result in a fire hazard.
IMPORTANT NOTE: Caution must be used in planning the
proper installation of the Wolf gas cooktop to avoid fires or
damage to adjacent cabinetry or kitchen equipment.
Follow all minimum clearances to combustible surfaces
shown in the installation illustration for your specific
model.
IMPORTANT NOTE: When multiple cooktops are installed
side by side, each unit must have its own separate recom-
mended electrical circuit. When multiple gas cooktops are
installed next to one another, they can receive their gas
supply from a common line. However, each unit must have
its own gas pressure regulator.
There should be at least 51/2" (140) clearance between the
countertop and any combustible surface directly below
the gas cooktop.
Wolf gas cooktops are intended for indoor use. An
adequate supply of fresh air is required to assure proper
combustion and ventilation. The location of the cooktop
should be away from strong draft areas, such as windows,
doors and strong heating vents or fans. Do not obstruct
the flow of air.

EXPLOSION HAZARD: Use a certified gas supply line
and install a gas shut-off valve. Securely tighten all gas
connections. Failure to follow these instructions can
result in explosion, fire or death.
to a regulated gas supply.
A gas supply line of 3/4" rigid pipe must be provided to the
cooktop. For LP gas, piping or tubing size can be 1/2"
minimum. LP gas suppliers usually determine the size and
materials used on the system. If local codes permit, a
certified, 1/2" or 3/4" ID flexible metal appliance connector
is recommended to connect the cooktop to the gas supply
line. The gas pressure regulator on the cooktop has 1/2"
female threads.
IMPORTANT NOTE: This installation must conform with
local codes and ordinances. In the absence of local
codes, installations must conform with the American
National Standard, National Fuel Gas Code.
IMPORTANT NOTE: The supply line must be equipped
with an approved external gas shut-off valve located near
the cooktop in an accessible location. Do not block
access to the shut-off valve. Refer to the illustration below.
TYPES OF GAS
There are two types of gas, natural and liquid propane
(LP). Conversions are required in order for appliances
designed for one gas to be operated with the other gas.
Such conversions must be performed by a Wolf authorized
service center. Make sure your gas cooktop is correctly
adjusted for the type of gas being used.
Wolf natural gas cooktops will function up to an altitude
of 10,250' (3124 m) without any adjustment. LP gas
cooktops will function up to 8,600' (2621 m) without
adjustment. If the installation exceeds these elevations,
contact your authorized Wolf dealer for a high altitude
conversion kit.
The product rating plate has information on the type of
gas that should be used. If this information does not agree
with the type of gas available, check with the local gas
supplier. The rating plate is located on the underside of
the cooktop. Refer to the illustration on page 3.
Before connecting the gas supply, make sure all valves
are in a closed position. Do not connect the gas supply
to an appliance that shows any sign of damage.

WC. A natural gas pressure regulator is installed.
LP Gas: Standard orifices are set for 10" (25 mb) WC.
An LP gas pressure regulator is installed.
Gas Supply Pressure: The maximum gas supply
pressure to the regulator should never exceed 14"
(34.9 mb) WC; .5 psi (3.5 kPa) for natural and LP gas.
The minimum line pressure is 7" (17.5 mb) WC for
natural gas and 11" (27.4 mb) WC for LP gas.
The Wolf gas cooktop requires a 120 V AC, 60 Hz electri-
cal supply to operate the electronic ignition system. The
service should have its own 15 amp circuit breaker. A
ground fault circuit interrupter (GFCI) is not recommended
and may cause interruption of operation.
•
Gas Pressure Regulator: To control and maintain a
uniform gas pressure in the gas manifold, the unit must
be used with a gas pressure regulator. The burner
orifices, etc. are sized for the gas pressure delivered by
the supplied regulator. Do not remove the regulator.
The cooktop is equipped with a power cord with a 3-prong
grounding plug. To minimize shock hazard, the power cord
must be plugged into a mating 3-prong grounded outlet,
grounded to conform with the National Electrical Code,
ANSI/NFPA 70 latest edition, or Canadian Electrical Code
(CSA) and all local codes and ordinances. Refer to the
illustration below.
The maximum gas supply pressure to the regulator
should never exceed 14" (34.9 mb) WC; .5 psi (3.5 kPa).
IMPORTANT NOTE: Do not ground to a gas pipe.

wolfappliance.com/specs
Remove the cooktop, gas pressure regulator, burner
grates and burner caps from the shipping package.
GAS PRESSURE REGULATOR
Install the gas pressure regulator with the arrow on the
regulator pointing up toward the unit and in a position
where you can reach the access cap. Refer to the illustra-
tion below.
Lower the cooktop into the countertop cut-out opening.
Center the cooktop in the opening and check that the
front edge of cooktop is parallel to the front edge of the
countertop. Check that all required clearances are met.
Using a pencil, outline the rear edge of the cooktop frame
on the countertop. Remove the cooktop from the counter-
top opening.
IMPORTANT NOTE: All connections must be wrench-tight-
ened. Do not make connections to the regulator too tight,
as this may crack the regulator and cause a gas leak. Do
not allow the regulator to turn on the pipe when tightening
fittings.
IMPORTANT NOTE: When repositioning the cooktop in the
countertop opening, lift the entire cooktop up from the
opening to prevent scratching the countertop.
Apply the foam strip, included in the hardware package,
to the underside of the cooktop frame. Refer to the illus-
tration below.

GAS SUPPLY CONNECTION
SURFACE BURNERS
Assemble the flexible metal connector from the gas supply
pipe to the gas pressure regulator. You will need to deter-
mine the fittings required, depending on the size of your
gas supply line, flexible metal connector and shut-off
valve. Refer to the illustration below.
The surface burners use electronic igniters in place of
standing pilots. When the cooktop control knob is pushed
in and turned to the HIGH position, the system creates a
spark to light the burner. This sparking continues until the
electronic ignition senses a flame.
Use a pipe joint compound made for use with natural and
LP gas. If a flexible metal connector is used, be sure the
tubing is not kinked.
Before lighting, place the burner head and cap on each
burner base and position the burner grates.
To check operation of the surface burners, push in and
turn each control knob to the HIGH position. The flame
should light within four seconds.
Open the shut-off valve in the gas supply line. Wait a few
minutes for the gas to move through the line. Refer to the
illustration on page 10.
If the burners do not light properly, turn each control knob
to the OFF position. Check that burner heads and caps
are in the proper position. Check that the power cord is
plugged in and that the circuit breaker or house fuse has
not blown. Check that the gas shut-off valve is in the open
position. Check operation again, waiting at least five
minutes; if the burners do not light properly, contact a
Wolf authorized service center.
GAS LEAK TESTING
Use a brush and liquid detergent to test all gas connec-
tions for leaks. Bubbles around connections will indicate a
leak. If a leak appears, shut off the gas supply and adjust
connections. Then check connections again. Clean the
detergent solution from the cooktop.
IMPORTANT NOTE: Initial lighting of the surface burners
may take slightly longer, as air in the system must be
purged before gas can be supplied to the burner.
Never test for a gas leak with a match or other flame.
