Electrical Requirements

9CAUTION

Do not use an extension cord with the gas cooktop.

This appliances requires a 60 Hz, 15 Amp, 120 VAC connection. Plan the installation so that the power connection is accessible from the front of the cabinet.

Gas Requirements

Supply Pressure:

•Natural Gas - 7 inches water column (14.9 Millibars) minimum.

•Propane Gas -11 inches water column (27.4 Millibars) minimum.

The propane gas tank must be equipped with its own high pressure regulator in addition to the pressure regulator supplied with this unit. The cooktop is shipped from the factory for use with natural gas. For use with LP conversion a qualified technician or installer must do the conversion.

Cabinet Requirements

Dimension requirements in Figures 1 and 2 are for combustible surfaces. When the surface is protected by a material listed by UL as a Floor Protector and Wall Shield covered with not less than No. 28 MSG sheet metal 0.015 inch (0.38mm) stainless steel, 0.024 inch (0.6mm) aluminum or copper, it is considered noncombustible and some dimensions may be reduced. For a noncombustible surface over the cooktop, the minimum clearance is 24" (61cm) rather than 30" (76cm).

•Instructions are based on standard American cabinets 36" high (91cm) x 24" deep (61cm) with a 25" (63cm) countertop.

•Provide approximately a 10 square inch opening (65cm2) in the toe kick area or other cabinet area for adequate air inlet to the cabinet if installed with a downdraft.

Note: The appliance should not be installed with a ventilation system that blows air downward toward the burners. This type of ventilation system may cause ignition and combustion problems with the gas cooking appliance resulting in personal injury or unintended operation.

Installation Procedure

9WARNING

To avoid electrical shock hazard, before installing the cooktop, switch power off at the service panel to prevent the power from being switched on accidentally.

Figure 4: Counter Cutout – Foam Tape Placement

Prepare the Countertop

Cut out the countertop per the dimensions shown in

“Cabinet Requirements” on page 3.

Some solid surface materials, such as Surell™ and Corian®, require different cutting methods. Consult with the solid surface manufacturer for the correct cutting method needed. Apply heat reflective tape such as Scotch Aluminum Foil Tape #425 or #427 (not included) around the cutout so that it folds over on the top and sides. Do not wrap the tape underneath the cooktop. Be sure the tape extends beyond the outermost flange of the cooktop. All corners should be covered with tape.

Figure 6: Rough-in Box Area

Install the pressure regulator (supplied with unit) to manifold pipe using Teflon tape on threads of manifold pipe. Turn to hand tighten plus 1/4 turn, not exceeding 1 turn for alignment. To prevent possible damage to the gas pressure regulator, install it after the rough-in box is in its permanent position. When the regulator is securely installed on the manifold pipe, the conversion nut will be easily accessible.

Figure 7: Pressure Regulator

9WARNING

Do not attempt any adjustment of the pressure regulator, except conversion to propane..

Connect the gas supply line to the unit pressure regulator using a 1/2" flex gas line connector between manual shutoff valve and pressure regulator. Always use a new flex line.

Figure 8: Gas and Electrical Location

Check supply line connections for leaks using a soap solution. Do not use a flame of any sort.

1.Turn on gas.

2.Apply a non-corrosive leak detection fluid to all joints and fittings in the gas connection between the shut-off valve and the range. Include gas fittings and joints in the range if connections may have been disturbed during installation. Bubbles appearing around fittings and connections indicate a leak.

3.If a leak appears, turn off supply line gas shut-off valve and tighten connections.

4.Retest for leaks by turning on the supply line gas shutoff valve. When leak check is complete (no bubbles appear), test is complete.

5.Wipe off all detection fluid residue.

Important Notes for Gas Connection:

•The appliance and its individual gas shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5kPa).

•The appliance 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 (3.5kPa).

Connect Electrical Supply

Before connecting 5-foot (1.5 m) supply cord to wall receptacle, make certain that gas shutoff valve and all burner controls are in OFF position.

English 6

Burner Cap Placement

9WARNING

To prevent flare-ups, do not use the cooktop without all burner caps and all burner grates properly positioned.

9WARNING

To prevent burns, do not touch burner caps or grates while hot. Turn the cooktop off and allow the burners to cool.

Do not attempt any adjustment of the pressure regulator, except conversion to propane.

The burner caps must be properly placed for the cooktop to function properly. If the burner cap is not properly placed, one or more of the following problems may occur:

•Burner flames are too high.

•Flames shoot out of burners.

•Burners do not ignite.

•Burner flames light unevenly.

•Burner emits gas odor.

Placing Burner Caps

Each cap has a letter (A, D, or F) cast in the underside of the cap that corresponds to a letter (A, D, or F) cast in the burner base that is attached to the appliance.

•After electrical connection is complete, place each burner cap on its correct burner base per its corresponding letter designation. See figure “Burners Caps” on page 7.

•Place burner cap gently on top of base so that the prongs of the burner base fit snugly into the groove of the burner cap.

Checking Burner Cap Placement	• You may gently try to move the burner cap from side to
• Check to make sure there is not gap between the	side to check if it is properly placed. If properly placed,
	the cap will click from side to side as the prongs hit the
burner cap and burner base. See figure “Burner Cap	groove ridge.

Install Burner Grates

Properly position and install each burner grate as shown in the following illustrations. The center grate will seat with rubber feet fitting to indentatations in the cooktop surface. Check to be sure the feet match the indentations.

30” 4 Burner

English 8

36” 5 Burner

9WARNING

To prevent flare-ups, properly support pots, and avoid spills, all grates must be properly positioned on the cooktop whenever the cooktop is in use. Each of the four feet must be placed into the corresponding dimples in the cooktop. Do not use a grate if the rubber feet are missing or damaged.

For replacement rubber feet: Part # 416438, contact your dealer or call the service number listed inside the cover.

Final Check

Check operation of electric igniters. Check flame characteristics. Flame should be blue with no yellow tip.

Yellow Flames:

Further adjustment is required.

Yellow Tips on Outer Cones:

Normal for LP Gas.

Soft Blue Flames:

Normal for Natural Gas.

If the flame is completely or

mostly yellow, verify that the regulator is set for the correct fuel. After adjustment, retest.

Some yellow streaking is normal during the initial startup. Allow unit to operate 4-5 minutes and re-evaluate before making adjustments.
