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 manual, 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.

The appliance may experience ignition problems if not properly grounded and polarized.

Installation 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:

• I

3P – G31 at 37 mbar

• I2E – G20 at 20 mbar

• I

2E+ – 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 accordance 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 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 tightening 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.
