ATTACHING THE COOKTOP

To prevent liquids from leaking accidentally into the underlying storage space, the appliance is equipped with a special gasket. To apply this gasket:

1. Lay out the protective sealing strips along the edges of the opening in the countertop and carefully overlap the strip end.
2. Insert the cooktop into the countertop opening.
3. With a screwdriver, assemble brackets to the cooktop bottom with the screws (See below diagram).
4. Slide the hooks into position and secure them with the screws.
5. Trim the part of the sealing strips which extend beyond the hotplate base.

CONNECTING GAS TO COOKTOP

Before installing the cooktop consider the location of the gas supply and routing the gas line.

• This cooktop is designed to operate at a pressure of 4″ of the water column on natural gas or 10″ of the water column on propane gas (LPG).

• This cooktop can be converted for use with Liquid Propane gas (LPG). When using this cooktop with LPG gas, the conversion must be made by a qualified installer before attempting to operate the cooktop with that gas. LP kit can be purchased from an authorized Cosmo dealer or contact Cosmo Customer Service for further assistance.

• For correct operation, the pressure of natural gas supplied to the regulator should be between 4″ and 5″ of the water column. For LP gas, the pressure supplied must be between 10″ and 12″ of the water column.

• For NG: The gas supply is connected to the regulator loose. The inlet connection has a 1/2″ B.S.P. male thread. IT IS ESSENTIAL THAT THE ELBOW ON THE APPLIANCE BE HELD FIRMLY WITH A SPANNER WHEN CONNECTING THE SUPPLY. DO NOT OVER TIGHTEN. The regulated pressure for NG is 4″ W.C. (See diagram).

• For LPG: The gas supply is connected to the regulator loose. The inlet connection has a 1/ 2″ B.S.P. male thread. IT IS ESSENTIAL THAT THE ELBOW ON THE APPLIANCE BE HELD FIRMLY WITH A SPANNER WHEN CONNECTING THE SUPPLY. DO NOT OVER TIGHTEN. The regulated pressure For LPG is 10″ w.c. (See diagram).

• When checking for the correct operation of the regulator, the inlet pressure must be at least 1″ more than the operating manifold pressure as given above.

• The pressure regulator located at the inlet of the cooktop manifold must remain in the supply line regardless of Natural (NG) or Liquid Propane (LP) gas is being used.

• A flexible metal appliance connector used to connect the cooktop to the gas supply should be 3 feet/91.4 cm max. in length for easy installation. In Canada, flexible connectors should be single-wall metal connectors less than 6 feet / 182.9 cm in length.

• Shut off the main gas supply valve before removing the old cooking appliance (if applicable) and leave it off until the new hook-up has been completed. Don’t forget to relight the pilots on other gas appliances when you turn the gas back on.

• Because hard piping restricts the movement of the cooktop, the use of a CSA-certified flexible metal appliance connector is recommended unless local codes require a hardpiped connection. Never reuse an old connector when installing a new cooktop. If the hard piping method is used, you must carefully align the pipe.

To prevent gas leaks, use pipe joint compound resistant to NG gases on all- male external pipe threads.

1. In an easily accessible location, install a service manual gas shut-off valve. Be sure everyone operating the cooktop knows where and how to shut off the gas supply to the cooktop.

2. Use a flexible gas line to connect to the 1/2″ fitting, located on the bottom righthand corner underneath the cooktop. For gas inlet position, refer to diagrams below.

3. When all connections have been made, be sure all cooktop controls are in the OFF position and turn on the main gas supply valve. Check for gas leaks by using a 75% water, 25% dishwashing soap solution. If a gas leak is present, shut off the gas immediately, tighten all connections, and retest for leaks.

NOTE: Any opening in the wall behind the appliance and in the floor under the appliance shall be sealed.

Rubber Pad Installation on Back Panel

OPERATING INSTRUCTIONS

GUIDELINES FOR USING COOKTOP BURNERS

WARNING!: Keep cooktop area clear and free from combustible materials, gasoline, and other flammable vapors and liquid.
WARNING!: DO NOT use the cooktop as a room/space heater; this may result in carbon monoxide poisoning.

• This appliance is intended for cooking food; it must NOT be used for any other purpose.
• Never leave the range top unattended when in use. Boil over causes smoking and greasy spills that may ignite.
• Never allow flames to extend beyond cookware or curl up its sides. This could discolor  and damage the utensil and you may get burned by a hot handle.
• Keep handles out of the way. Turn handle so that they don’t extend over the edge of the range or another burner that is on.
• Use caution when deep-frying. Oil or fat can overheat very quickly, particularly on a high setting.
• Make sure that all burner parts are properly in place and ensure burner caps are installed correctly. Incorrectly or incompletely assembled burners may produce dangerous flames. see “Care & Maintenance”, Page 25.
• Keep the burners clean. Especially after a spill or boil over, make sure you clean the affected burners before using them again. Food residue may clog the igniter and the notches of the flame spreader, stopping the burner from functioning correctly. See “Care & Maintenance” on Page 25.
• Check that the burner flames are regular. They should be blue with no yellow tipping and burn without fluttering all around the burner cap. For burner troubleshooting, see Page 2/.
• DO NOT store dangerous or flammable material in the cabinet areas above the cooktop.
• DO NOT use aerosol sprays in the vicinity of the cooktop while it’s operating.
• DO NOT use unstable or deformed cookware to avoid safety hazards, such as spillovers.
• Always ensure that the knobs are in the “OFF” position when the cooktop is not in use.
• The cooktop must be regularly cleaned and maintained for safe use; see Page 25.
• Before maintenance and cleaning, disconnect the appliance from power and allow it to cool completely.
• Ensure that air can circulate around the gas cooktop; poor ventilation can result in a lack of oxygen and extinguish the flame.
• The cooktop produces heat and humidity in the room where it is installed.
• There are dual burners that have the same low turn-down setting (SIM) for gentle simmering (620 BTU/hour). Use the SIM setting for melting chocolate and butter, cooking rice and delicate sauces, simmering soups and stews, and keeping cooked food hot.
• Ensure the room where the cooktop is installed is well-ventilated. Keep adequate natural ventilation or install a range hood with a discharge tube.
• Supply the cooktop with the type of gas stamped on the relevant label situated in the immediate vicinity of the gas connection tube.

SURFACE BURNER IGNITION

Light the burners before placing pans on the grid and check that the flame is regular.

1. Push and turn the appropriate control knob counter-clockwise to the “IGNITE” position; you will hear a clicking noise the sound of the electric spark igniting the burner.
2. Once burner ignition has been achieved, then turn the burner control knob to adjust the desired heat setting (See diagram). Reduce the flame size by turning the knob counter-clockwise to your desired flame height.

If the burner does not light, turn the knob to its original position and try again. Always lower the flame or turn it off before removing the pan.

NOTE: When first used, the gas burner will not ignite immediately. Hold the knob pressed down for an extended time for the gases to fully fill the operating system.
NOTE: When one burner is turned to the “HI” position, the burner igniters will spark.
Do not attempt to disassemble or clean around any burner while another burner is on. Do not touch any burner cap, burner base, or igniter while the igniters are sparking.

GRIDDLE IGNITION (FOR 48 IN. MODELS ONLY)

Before using the Griddle

1. Clean the griddle thoroughly with warm, soapy water to remove dust or protective coating. Rinse with clean water and wipe off to dry with a soft, clean, lint-free cloth.

3. Make sure the grease tray is under the front edge of the griddle; position the tray under the griddle overhang to catch grease or food residue.

Using the Griddle

1. Push and turn the control knob counter-clockwise to the preferred cooking temperature.
2. Preheat the griddle for approximately 10-12 minutes.
3. When the griddle is preheated to the desired temperature, the indicator light will turn on.
4. Place the food on the griddle to cook.

TIP: Butter or cooking oil can be added for more flavor.

CAUTION!: The griddle surface will be hot after use; allow it to cool before cleaning.

TIPS FOR USING POTS & PANS CORRECTLY

Always ensure that the bottom and handles of pots and pans do not overextend from the cooktop. When cooking with flammable fat such as oil, do not leave the range unattended. Use pots of the appropriate size on each burner using the following chart:

BURNER & RECOMMENED POT/PAN SIZE

• Auxiliary: 3 1/2 – 5 1/2 in. (9O – 140mm)
• Semi Rapid: 5 1/2 – 10 1/4 in. (140 – 260mm)
• Rapid: 7 1/8 – 10 1/4 in. (180 – 260mm)
• Dual Burner: 8 2/3 – 10 1/4 in. (220 – 260mm)

When boiling liquids, turn the knob to the MINIMUM position once boiling is reached to avoid overflow. Always use pots with a matching lid. Dry the bottom of cookware before cooking. Use pots with a flat, thick bottom (except for wok cooking).

WOK COOKING

Always use the wok adapter supplied with the range. Wok pan external diameter shall not be smaller than 10″ (25cm) and larger than 16″ (40cm).

WARNING!: DO NOT use an open flame when checking for leaks.
