Safety IMPORTANT SAFETY NOTICE READ ALL INSTRUCTION BEFORE INSTALLING AND OPERATING THIS APPLIANCE • Remove all tape and packaging before using the cooktop. Never allow children to play with packaging material. Do not remove the model/serial plate attached to the cooktop. • Be sure your appliance is properly installed and grounded by a QUALIFIED TECHNICIAN in accordance with the National Fuel Gas Code ANSI Z223.1—latest edition in the United States, or in Canada CAN/CGA B149.1, and CAN/CGA B149.
• Installation and service must be performed by a qualified installer, servicer or the gas supplier. Ask your dealer to recommend a qualified technician and an authorized repair service. Know how to shut off gas supply at the meter and disconnect the electrical power to the cooktop at the circuit breaker or fuse box in case of an emergency. • Do not repair or replace any part of the appliance unless specifically recommended in the manuals.
• DO NOT TOUCH THE COOKTOP SURFACE, THE BURNERS, GRATES OR ANY AREAS NEAR THEM. Surface burners or cooktop may be hot even though flames are not visible. Areas near surface burners or cooktop may become hot enough to cause burns. During and after use, do not touch, or let clothing or other flammable materials touch these areas until they have had sufficient time to cool. Among these areas are the cooktop and surfaces facing the cooktop.
• Never use this appliance as a space heater to heat or warm the room. Doing so may result in carbon monoxide poisoning and overheating of the oven. • Know which knob controls which surface burner. Visually check that the burner has lit. Then adjust the flame so it does not extend beyond the edge of the utensil. • Clean the appliance regularly to keep all parts free of grease that could catch fire. Exhaust fan ventilation hoods and grease filters should be kept clean.
• Always use proper flame size. Adjust flame size so it does not extend beyond the edge of the utensil. The use of undersized utensils will expose a portion of the burner flame to direct contact and may result in ignition of clothing. Proper relationship of utensil to flame will also improve efficiency. • Use the proper pan sizes. This cooktop is equipped with surface units of different sizes. Select utensils having flat bottoms large enough to cover the surface unit.

Getting Started Grounding Instructions • This cooktop features a pilotless electric ignition for energy savings and reliability. It operates on a 120 volt, 60 Hz power supply. A separate circuit, protected by a 15 amp time delay fuse or circuit breaker, is required. For personal safety, the cooktop must be properly grounded. A properly-grounded 3prong receptacle (see Figure 1) should be located 12” below the countertop and within reach of the cooktop’s four-foot power cord.
• Any additions, changes or conversions required in order for this appliance to satisfactorily meet the application needs must be made by a qualified service technician in accordance with the manufacturer’s instructions and all codes and requirements of the authority having jurisdiction. Failure to follow the instructions could result in serious injury or property damage. The qualified agency performing this work assumes responsibility for the conversion.
• Never extend the flame beyond the outer edge of the utensil (see Figure 2). A higher flame simply wastes heat and energy, and increases your risk of being burned by the flame. Figure 2 Proper Burner Adjustments • The color of the flame is the key to proper burner adjustment. A good flame is clear, blue and hardly visible in a well-lighted room. Each cone of flame should be steady and sharply defined. Adjust or clean burner if flame is yellow-orange.
Placement of Burner Heads and Caps For all burners: • Place a burner cap on each burner head (see Figure 4), matching the cap size to the head size. The cap for each burner has an inner locating ring which centers the cap correctly on the burner head. Be sure that all the burner caps and burner heads are correctly placed Figure 4 BEFORE using your appliance. • Make sure each burner cap is properly aligned and level (see Figure 5). • Turn the burner on to determine if it will light.

Care and Cleaning IMPORTANT To avoid possible burns use care when cleaning the cooktop. DO NOT attempt to clean the cooktop whenever the cooktop or burner heads are still hot. To avoid possible burns DO NOT attempt any of the following cleaning instructions before turning OFF ALL of the surface burners and allowing them to cool. • Control Knobs - For general cleaning, use hot, soapy water and a cloth. For more difficult soils and built-up grease, apply a liquid detergent directly onto the soil.
Solutions to Common Problems IMPORTANT Before calling for service, review this list. It may save you both time and expense. This list includes common experiences that are not the result of defective workmanship or material in your cooktop. PROBLEM POSSIBLE REASONS Burner cap SOLUTIONS The burner is not installed correctly. Install the burner pieces again. Check all connections to the ignition module. No spark occurs when lighting burner Igniter Igniter is not positioned correctly.
PROBLEM The flame goes out during operation POSSIBLE REASONS The thermocouple is contaminated by food residue. Clean the thermocouple. The flame is too low and cannot reach the thermocouple. Adjust the flame a little higher. Nozzle The burner is connected with a natural gas nozzle and needs to be connected with a propane nozzle Change the natural gas nozzle to a liquid propane nozzle. (Use the supplied screwdriver when changing the nozzles.
Advance Preparation • For proper operation of a gas appliance, the air necessary for the combustion of the gas must be able to flow into the room naturally. The air must flow into the room directly through openings in the outside walls. These openings must have an unobstructed cross-section not less than 2m3/hfor each kw of power (see total power in kw on the appliance). • This opening must be constructed so that it will not be obstructed from inside or outside, or constructed close to the floor.
Provide an Adequate Gas and Electrical Supply • Installation must comply with local codes. In the absence of local codes, the gas cooktop must comply with the National Fuel Gas Code ANSI Z223.1—latest edition in the United States, or in Canada CAN/CGA B149.1, and CAN/CGA B149.2, and the National Electrical Code ANSI/NFPA No. 70—latest edition in United States, or in Canada CSA Standard C22.1, Canadian Electrical Code, Part 1, and local code requirements.
