INSTALLATION INFORMATION
This section of the manual covers some of the installation issues that a service technician may need to know when
servicing a Wolf Gas Cooktop. If additional installation information is needed after reviewing this section of the man-
ual, please refer to the Installation Guide or contact the Wolf Appliance Customer Service Department.
Electrical Requirements:
•110-120 volts AC, 60 Hertz, 15 amp fused electrical supply.
• “ICB ONLY” 220-240 VAC, 50/60 Hz, 15 amp fused electrical supply.
•A timed-delay fuse or circuit breaker is recommended.
•Separate circuit serving only this appliance.
•Installation site must be equipped with a properly grounded 3-prong receptacle.
This appliance when installed must be properly grounded. This appliance is equipped with a 3-prong (grounding)
plug. The power cord must be plugged into a mating 3-prong ground-type receptacle. (See Figure 3-1).
If a mating receptacle is not available, it is the obligation of the customer to have a properly grounded, 3-prong
receptacle installed by a qualified electrician.
If the electric receptacle or the power cord are not properly grounded and polarized, a shock hazard could exist and
the appliance may experience ignition problems.
• A SHOCK HAZARD COULD EXIST IF THE ELECTRIC RECEPTACLE OR THE POWER CORD ARE NOT
PROPERLY GROUNDED AND POLARIZED.
• TO AVOID SHOCK HAZARD, NEVER REMOVE THE GROUNDING PRONG FROM THE PLUG OF THE
POWER SUPPLY CORD.

SSEERRIIEESSInstallation Information
Gas Requirements:
NOTE: All Wolf gas appliances are manufactured to
work with natural gas or LP gas (Liquid Propane gas).
Natural Gas Manifold Pressure
Standard natural gas orifices on the appliance are set
for 5” WC (Water Column Pressure).
Liquid Propane Manifold Pressure
The standard propane gas orifices on the appliance are
set for 10” WC (Water Column Pressure).
Gas Supply Line Size
• 1/2 inch
Gas Supply Pressure for Domestic Units
•Maximum line pressure for natural gas and LP is
14” WC; 1/2 psi (3.5 kPa).
•Minimum line pressure for natural gas is 7” WC.
•Minimum line pressure for LP gas is 11” WC.
ICB units are CE certified for the following gas type
and pressure:
•I3P – G31 at 37 mbar
•I2E – G20 at 20 mbar
•I2E+ – G20/25 at 20/25 mbar
•I2H – G20 at 20 mbar
Gas Pressure Regulator (Domestic Models Only)
To control and maintain a uniform gas pressure in the
gas manifold, Wolf gas appliances must be connected
to the gas supply line through a pressure regulator.
The burner orifices are sized for the pressure delivered
by the regulator. Never attempt to operate a Wolf gas
appliance without the use of the proper pressure
regulator.
* NOTE: ICB units do not utilize a gas regulator.
Gas Shut-off Valve
The supply line must be equipped with an approved
shut-off valve. This valve should be located in accor-
dance to all national, local codes and ordinances.
(See Figure 3-2).
Leak Testing
NEVER USE OPEN FLAMES TO CHECK FOR GAS
LEAKS. ONLY USE A LEAK TESTING SOLUTION
OF SOAPY WATER OR AN ELECTRONIC LEAK
DETECTOR. DO NOT USE LIQUID NEAR VALVE
STEMS.
The maximum gas supply pressure to the regulator
should never exceed 14” WC (Water Column
Pressure); 1/2 psi (3.5kPa)

Installation of Multiple Units
Integrated units can be installed together or with 30” or
36” cooktops. Where multiple units are installed side-
by-side, the cut out dimensions are added together.
Then add an additional space of 1-1/4” to each unit, to
get the total cutout width. (See Figure 3-7).

INSTALLATION PROCEDURE
•Insert cooktop into countertop opening and center
cooktop. Check that front edge of cooktop is parallel
to front edge of countertop. Check that all required
clearances are met.
•Use a pencil to outline rear of cooktop on counter-
top. Then remove cooktop from countertop.
•Apply foam strip around bottom of burner box flush
with edge. (See Figure 3-8).
•Reinsert cooktop into countertop opening. Check
that cooktop is parallel to front edge of countertop.
Lift entire cooktop to make adjustments, aligning
with pencil line.
•Attach brackets to burner box. Insert clamping
screws into brackets. Use a screw driver to tighten
clamping screws against underside of countertop.
(See Figure 3-8).
Note: Do not overtighten screws.
•Install pressure regulator with arrow on regulator
pointing up towards unit and in a position where
you can reach the access cap. (See Figure 3-9).
* NOTE: ICB units do not utilize a gas regulator.
•Assemble flexible metal connector from gas supply
pipe to pressure regulator. (See Figure 3-10).
•Use a pipe-joint compound made for natural and LP
gas. If a flexible connector is used, be certain the
tubing is not kinked.
Note: All connections must be wrench tightened. Do
not make connections to regulator too tight. Making
connections too tight could crack pressure regulator.
Do not allow regulator to turn on pipe when tighten-
ing fittings.
•Open shut-off valve in supply line. Wait a few min-
utes for gas to move through line.
•Leak testing of appliance shall be conducted accord-
ingly using a soapy water solution or an electronic
leak detector.
* NOTE: ICB units requrie an electrical gas shut off valve that
must be energized before gas will flow to burners.
The maximum gas supply pressure to the regulator
should never exceed 14” WC (Water Column
Pressure); 1/2 psi (3.5kPa)
NEVER USE OPEN FLAMES TO CHECK FOR GAS
LEAKS. ONLY USE A LEAK TESTING SOLUTION OF
SOAPY WATER OR AN ELECTRONIC LEAK DETECTOR.
DO NOT USE LIQUID NEAR VALVE STEMS.

These instructions contain procedural information to install the Integrated Filler Strip Kit into countertop installations.
1. Locate center of Filler Strip Bracket (2) at required distance from cooktop cutout edge.
2. Position Filler Strip Bracket (2) so that top surface is flush with counter top. You may need a
straight edge to assist in locating bracket at correct height.
3. Mark center of elongated slots of Filler Strip Bracket (2) on front and rear of cooktop cutout.
4. Using a 3/32" drill bit, drill a ¾" deep pilot hole for the #6/32 (3) mounting screws.
5. Secure Filler Strip Bracket (2) to counter top.
6. Install all cooktops into corresponding openings.
7. Position Filler Strip (1) into Filler Strip Bracket (2) and install three #10-24 nuts (4), but do not tighten.
8. Align and adjust cooktops and filler strips in countertop opening and then tighten cooktop hold down
clamps and filler strip nuts.
