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 ampere 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 2-1).
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 ELEC-
TRIC 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 CORD.

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
•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.
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 2-2).
NEVER USE OPEN FLAMES TO CHECK FOR GAS
LEAKS. ONLY USE A LEAK TESTING SOLUTION

Gas Pressure Regulator
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 regu-
lator.
