INSTALLATION OPTIONS

MULTIPLE COOKTOP INSTALLATION:

If the gas cooktop is to be used with any combination of additional cooktop units or modules with a filler strip, the cut-out width is calculated by adding the corresponding units’ cut-out dimensions plus 11/4″ (32) for each additional unit. Refer to the illustration below.

IMPORTANT NOTE: When multiple units are installed side by side, each unit must have its own separate recommended electrical circuit. When multiple gas units are installed next to one another, they can receive their gas supply from a common line. However, each unit MUST have its own regulator installed between the mainline and the gas cooktop. When two or more modules are installed together, an integrated module filler strip (IFILLER/S) is recommended. If a downdraft ventilation system is also installed, an integrated module support for downdraft ventilation (ISUPPORT) is also required (Model DD30 only). Contact your Wolf dealer for information on these accessory components. WOLF-CT15G-S-Gas-Cooktops-fig-6

GAS SUPPLY REQUIREMENTS

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 and National Electrical Code regulations.

EXPLOSION HAZARD—
Use a new CSA approved gas supply line and install a gas shut-off valve. Securely tighten all gas connections. For LP gas, have a qualified technician make sure the gas pressure does not exceed 14″ (34.9 mb) WC (water column). Failure to do so can result in explosion, fire or death.

IMPORTANT NOTE: The gas cooktop must be connected to a regulated gas supply.
IMPORTANT NOTE : This installation must conform with local codes and ordinances. In the absence of local codes, installations must conform with American National Standard, National Fuel Gas Code ANSI Z223.1 – latest edition or CANI – B149.1 or 2.
IMPORTANT NOTE: The natural gas cooktop is rated for elevations up to 8,000′ (2438 m) without adjustment. Install a high altitude kit for elevations from 8,000′ (2438 m) to 10,000′ (3084 m). The LP gas cooktop is rated for 10,000′ (3084 m).

The cooktop is equipped for use with natural or LP gas. It is design certified by the Canadian Standards Association (CSA) for natural or LP gases. The rating plate, located on the underside of the burner box, 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. Provide a gas supply line of 3/4″ rigid pipe to the cooktop location. A smaller size pipe on long runs may result in insufficient gas supply. Pipe joint compounds, suitable for use with LP gas should be used. 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 new CSA designcertified, 4–5′ (1.2–1.5 m) long, 1/2″ or 3/4″ ID, flexible metal appliance connector is recommended for connecting this cooktop to the gas supply line. Do not kink or damage the flexible connector when moving the cooktop. The pressure regulator has 1/2″ female pipe threads. You will need to determine the fittings required, depending on the size of your gas supply line, flexible metal connector and shutoff valve. If rigid pipe is used as a gas supply line, a combination of pipe fittings must be used to obtain an in-line connection to the cooktop. All strains must be removed from the supply and gas lines so the cooktop will be level and in line.

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. The inlet pressure to the regulator should be as follows for operation and checking the regulator setting:

Natural Gas: Set pressure 5″ (12.5 mb) WC, supply pressure 7–14″ (17.5–34.9 mb) max.
LP Gas : Set pressure 10″ (25 mb) WC, supply pressure 11–14″ (27.4–34.9 mb) WC.

LINE PRESSURE TESING:

Testing above 1/2 psi (3.5 kPa) 14″ (34.9 mb) WC (gauge): The cooktop and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures greater than 1/2 psi (3.5 kPa).
Testing below 1/2 psi (3.5 kPa) 14″ (34.9 mb) WC (gauge) or lower : The cooktop 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 (3.5 kPa).

ELECTRICAL REQUIREMENTS

IMPORTANT NOTE : If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate.
IMPORTANT NOTE: Check with a qualified electrician if you are not sure whether the cooktop is properly grounded.
IMPORTANT NOTE: Do not ground to a gas pipe.

A 120 VAC, 60 Hz, 15-amp, fused electrical supply is required. A time-delay fuse or circuit breaker is recommended. It is recommended that a separate circuit serving only this appliance be provided. Electronic ignition systems operate within wide voltage limits, but proper ground and polarity are necessary. In addition to checking that the outlet provides 120 VAC power and is correctly grounded, the outlet must be checked by a qualified electrician to see if it is wired with correct polarity. A wiring diagram is provided in the literature package.

This appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 latest edition or Canadian Electrical Code (CSA).

RECOMMENDED GROUND METHOD

IMPORTANT NOTE : For your personal safety, this cooktop must be grounded. This cooktop is equipped with a 3-prong ground plug. To minimize possible shock hazard, the cord must be plugged into a mating 3-prong ground- type outlet, grounded in conformance with the National Electrical Code, ANSI/NFPA 70 latest edition*, or Canadian Electrical Code (CSA) and all local codes and ordinances. If a mating outlet is not available, it is the obligation of the customer to have a properly grounded, 3-prong outlet installed by a qualified electrician.
IMPORTANT NOTE** : If product is connected to a GFCI protected outlet, nuisance tripping of power supply may occur, resulting in loss of product operation.

WIRING DIAGRAM:

A wiring diagram covering the control circuit for each Wolf gas cooktop model can be found on page 15.

COOKTOP INSTALLATION

Remove the cooktop, pressure regulator, burner grates and burner caps from the shipping package. 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. Use a pencil to outline the rear edge of the cooktop on the countertop. Remove the cooktop from the countertop opening.

IMPORTANT NOTE: When repositioning the cooktop in the countertop cut-out opening, lift the entire cooktop up from the opening to prevent scratching the countertop. Remove the foam strip from the hardware package. Apply the foam strip around the bottom of the burner box flush with the edge as shown in the illustration below. Reinsert the cooktop into the countertop opening. Check that the cooktop is parallel to the front edge of the countertop. Lift the entire cooktop to make adjustments and align the rear edge with the pencil line. Attach the brackets to the burner box. Insert the 31/2″ (89) clamping screws into the brackets. Use a screwdriver to tighten the clamping screws against the underside of the countertop. Refer to the illustration below. Do not overtighten screws.

PRESSURE REGULATOR:
Install the 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 illustration below.

IMPORTANT NOTE: All connections must be wrench-tightened. Do not make connections to the gas 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. WOLF-CT15G-S-Gas-Cooktops-fig-8

GAS SUPPLY LINE CONNECTION:

Assemble the flexible metal connector from the gas supply pipe to the pressure regulator. You will need to determine the fittings required, depending on the size of your gas supply line, flexible metal connector and shutoff valve. Refer to the illustration below. 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. 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.

GAS LEAK TESTING

Use a brush and liquid detergent to test all gas connections for leaks. Bubbles around connections will indicate a leak. If a leak appears, shut off gas valve controls and adjust connections. Then check connections again. Clean all the detergent solution from the cooktop.

INITIAL LIGHTING :

The surface burners use electronic igniters inplace 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. Be sure to place the burner heads and caps on each burner base and position the burner grates over the burner bases and heads before lighting. 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.

If the burners do not light properly, turn control knob to the OFF position. Check that the burner heads and caps are in the proper position. Check that the power supply cord is plugged in and that the circuit breaker or house fuse has not blown. Check that the shutoff valve is in the ON position. Check operation again, if the burners do not light properly at this point, contact a Wolf authorized service center.

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.
