Electrical Grounding Instructions
WARNING
This indoor gas cooking appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three pronged receptacle.
Where a standard two-prong wall receptacle is encountered, it is the responsibility and obligation of the customer to have it replaced with a properly grounded threeprong wall receptacle.
Do not cut or remove the grounding prong from the power cord.
Before connecting plug to the cord, disconnect the electrical supply.
CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
Connect Range to Gas Supply
Most localities will require that the stove shutoff valve and gas connections be installed by a certified technician or plumber. These instructions are for a professional.
Gas installation specifications and regulations may vary so please consult your local codes before proceeding.

1. Install a manual gas line shut-off valve in the gas line as follows:
   a. in an easily accessed location outside the range
   b. in the gas piping external to the appliance

2. Install male 1/2” flare union adapter to 1/2” NPT internal thread elbow at inlet of regulator.
   On models equipped with standard twin burners, install the male pipe thread end of the 1/2” flare union adapter to the 1/2” NPT internal thread at inlet of pressure regulator.
   Use a wrench on the regulator fitting to avoid damage.

Connect Range to Gas Supply

1. Install male 1/2” or 3/4” (3/4” for 48 inch gas range only) flare union adapter to the NPT internal thread of the manual shut-off valve, taking care to secure the shut-off valve to keep it from turning.
2. The gas supply pressure for checking the regulator setting is 6 in.w.c. (Natural Gas) and 11 inch.w.c. (LP gas). Connect flexible gas line connector to the regulator on the range. Position range to allow connection at the shut-off valve.
3. When all connections have been made, make sure all range controls are in position and turn on main gas supply valve.
4. Leak testing of the appliance shall be conducted according to the manufacturer’s instructions. Use some soap water (50% water and 50% soap) or a leak detector at all joints and connections to check for leaks in the system. Do not use a flame to check for gas leaks.
5. The appliance must be isolated from the building’s gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psig (3.5kPa).

After installation:

1. Check ignition of cooktop burners.
2. Check ignition of oven burner.
3. Visually check tubular burner (oven burner) re-ignition to be sure both rows of burner ports are relighting each time.
4. Check for gas leaks at all gas connections (using a gas detector, never a flame).
5. Check oven bake and convection bake function.

First Use

Conditioning the oven
Conditioning will burn off any manufacturing residues and ensure that you get the best results right from the start.
Follow these steps to condition your new stove’s oven:

1. Insert all the shelves.
   a. Both the side panels and shelves include a safety stop to keep them from sliding out of the oven when pulled forward
   b. The front stop prevents the shelves from hitting the back of the oven

2. Turn on the ventilation hood above your range on high.

3. Heat the empty oven at the highest temperature for:
   a. 30 minutes using BAKE
   b. 30 minutes using BROIL (some ovens only).

4. There will be a distinctive smell while you are conditioning the oven. This is normal, but make sure the kitchen is well ventilated during the conditioning.

5. Once cooled, wipe out the oven with a damp cloth and mild detergent, and dry thoroughly.

Cooktop Safety Guidelines

There are dual burners that have the same low turn-down setting (SIM) for gentle simmering (620 BTU/hr.). Use the SIM setting for melting chocolate and butter, cooking rice and delicate sauces, simmering soups and stews, and keeping cooked food hot.
✓ Never leave the cooktop unattended when in use. Boil over causes smoking and greasy spills that may ignite.
✓ Never allow flames to extend beyond cookware or curl up on sides. This could discolor and damage the utensil and you may get burned touching the hot handle.

Cooktop Safety Guidelines
✓ Keep handles out of the way. Turn handles so that they don’t extend over the edge of the range or on a burner that is on.
✓ Take care 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. Incorrectly or incompletely assembled burners may produce dangerous flames.
✓ 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. For instructions, see pages 41-43, “Cleaning Instructions”.
✓ Check the burner flames. They should be blue with no yellow tipping, and burn without fluttering all around the burner cap. If not, see pages 58-59, “Troubleshooting Guide” for Cooktop.To light the top burners, push and turn the appropriate control knob counter clockwise to the “HI” position. You will hear a clicking noise – the sound of the electric spark igniting the burner. Once burner ignition has been achieved, then turn the burner control knob to adjust the desired heat setting.

Cooktop Safety Guidelines

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.
Simmer and Boil
A smaller flame will give the best simmer results. Small flames offer precise cooking performance for delicate foods, keeping food warm, melting chocolate or butter, and for cooking that needs to cook over low heat for a long time.
The highest flame settings provides the maximum heat that is available on your range. This setting should be used for heavy cooking loads such as water boiling or pasta cooking. Flame Size
When you select the flame size, watch the flame when you turn the knob.
Any flame larger than the bottom of the cookware is wasted.The flame should be steady and blue in color. Foreign material in the gas line may cause an orange flame during initial operation.
Ignition Failure
If the gas does not ignite within four seconds, turn off the valve and allow at least five minutes for any gas to dissipate. Repeat the lighting procedure.
If the power fails, the cooktop cannot be operated safely. Do not attempt to operate during a power failure.
Cooktop
To prevent the cooktop from discoloring or staining, clean cooktop after each use, and wipe up acidic or sugary spills as soon as the cooktop has cooled.
Burner Grates
The grates must be properly positioned before cooking. Improper installation of the grates may result in scratching of the cooktop and / or poor combustion.

Oven Burner Use / Oven Safety Guidelines
Oven burner use To light the oven burner, push and turn the appropriate control knob counter clockwise to the (150 degrees Fahrenheit – 500 degrees Fahrenheit) position. You will hear a clicking noise – the sound of the electric spark igniting the burner. Once burner ignition has been achieved, then turn the burner control knob to adjust the desired heat setting.
Broil burner use
To light the broiler burner, push and turn the appropriate control knob clockwise to the broil position. You will hear a clicking noise – the sound of the electric spark igniting the burner. Keep pressing about 4 seconds until the burner ignition has been achieved.
IMPORTANT

Oven Safety Guidelines

✓ Do not block the ducts on the rear of the range when cooking in the oven. It is important that the flow of warm air from the oven and fresh air into the oven burner never be interrupted. Avoid touching the vent opening or nearby surfaces during oven or broiler operation because they are hot.
✓ Use all the oven modes with the oven door closed.
✓ Never use aluminum foil to cover the oven shelves or to line the floor of the oven.
The trapped heat can irreversibly damage the enamel and may even cause fire.

✓ Do not place water, ice, or any dish or tray directly on the oven floor, as this will irre- versibly damage the enamel.
✓ Do not cover the slotted grid of the broil/roast pan with aluminum foil. This will catch the grease and could cause fire.
✓ Do not use plastic wrap or wax paper in the oven.
✓ For food safety reasons, do not leave food in the oven for longer than two hours before and after cooking or defrosting. This is to avoid contamination by organisms which may cause food poisoning. Take care during warmer weather.
WARNING
According to the United States Department of Agriculture (USDA): DO NOT hold foods at temperatures between 40ºF to 140ºF more than 2 hours. Always cook foods to the internal temperatures as recommended by the USDA.
WARNING
Never cover any slots, holes or passages in the oven bottom or cover an entire rack with materials such as aluminum foil. Doing so blocks air flow through the oven and may cause carbon monoxide poisoning.
Aluminum foil lining may also trap heat, causing a fire hazard.
IMPORTANT
When using the oven for the first time, it must be operated for 15-30 minutes at a temperature of approximately 500 ° F without cooking anything inside to remove moisture and odors from internal insulation.

Oven Function

Natural Airflow Bake
Oven Functions
Occurs when heat is transferred into the oven from the bake burners in the bottom of the oven cavity. Heat is then circulated by natural airflow. This is the traditional bake setting.
Broil
The broil burner is located at the top of the oven. This burner heats the metal screen until it glows. The glowing screen produces the heat, searing the outside of broiled foods and sealing in juices.
Convection Bake
The oven convection fan circulates and distributes the heat in the oven for faster and even cooking. Convection cooking allows you to bake more items on multiple racks.
To bake using the convection fan:

1. Position the oven bottom cover and the oven shelves before using oven.

2. Remove any unused shelves and baking utensils from the oven.

3. Preheat the oven to the temperature stated in the recipe. Depending on the temperature andthe size of the oven, preheating will take around 15-20 minutes.

4. Arrange pans and food items evenly on the shelves. Make sure pans do not touch each other or the sides of the oven. When baking a single item, always center the item on the oven shelf. If baking on multiple shelves, make sure you stagger items on the shelves so that one is never directly above another.

5. When baking using convection, either reduce the temperature stated in the recipe and leave the baking time unchanged, or reduce the baking time by several minutes and leave the temperature unchanged. For foods with a baking time of over an hour,
   reducing both the temperature and time slightly may give the best results.

6. Dark metal baking pans or those with a dull finish absorb heat faster than shiny pans, and are excellent for pies and breads, or anything that needs browning or a crisper crust.

7. Shiny finished cookware may work best for foods that require lighter, delicate browning (e.g. cakes and cookies), as it reflects some heat and gives a less intense baking surface.

8. Avoid opening the oven door frequently during baking.

Convection Roast
For best results use the broiler pan. The pan is used to catch grease spills and has a cover to prevent grease splatter.
The convection fan circulates heated air around the food being roasted, sealing juices quickly for a moist and tender product while, at the same time, creating a rich golden-brown exterior.
Use the broil/roast pan and slotted grid supplied with the range when roasting in order to elevate the meat on a metal roasting rack. This allows hot air to circulate around the meat, browning it more evenly like a rotisserie. A suitable roasting rack can be purchased through Customer Care at: +1-888-784-3108.
When roasting larger items like a whole turkey, use only the pan and grid for greater stability.
Convection Defrost
With temperature control off, a motorized fan in the rear of the oven circulates air. The fan accelerates natural defrosting of the food without heat. To avoid illness and food waste, do not allow defrost food to remain in the oven for more than two hours without being cooked.
Defrosting
To thaw uncooked frozen food, set the oven temperature to 100°F – 150°F. Once thawed, cook the food immediately and do not refreeze.
To prevent liquid from thawing food dripping on the oven floor, be sure any uncooked food is tightly wrapped in foil and/or placed in a container.
Convection Dehydration
With the temperature control on 175°F, warm air is radiated from the bake burners on the bottom of the oven cavity, and is circulated by a motorized fan in the rear of the oven.
Over a period of time, the water is removed from the food by evaporation. Removal of water increases growth of microorganisms and detains the activity of enzymes.

Broiler Operation

Note: Door must be closed during broiler operation.
Broiling is a method of cooking tender cuts of meat directly under the broiler in the oven. Broiling in the oven is accomplished with the oven door closed. It is normal and necessary for some smoke to be present to give the food a broiled flavor.
If you open the oven door to check the food, have it open for as short a time as possible. This is to prevent the control panel from overheating and prevents melted knobs.
Use both the broil/roast pan and slotted grid supplied. The grid helps to reduce smoking and splatter by letting grease drip into the bottom of the pan, away from intense heat. To prevent food sticking, spray the grid with a light coating of non-stick cooking spray.

Preheating
Preheating is suggested when searing rare steaks (Remove the broiler pan before preheating with the broiler.
Foods will stick to hard metal). To preheat, turn the “Oven” selector knob to the “Broil” position. Wait for the burner to become hot, approximately 2 minutes. Preheating is not necessary when broiling meat well-done.
To Broil
Broil one side until the food is browned; turn and cook on the second side. Season and serve.
Always pull the rack out to the “stop” position before turning or removing food.
Setting Broil
The “Oven” selector knob controls the Broil feature. When broiling, heat radiates downward from the oven broiler for even coverage. The Broil feature temperature is 500°F (260°C).
The broil pan and insert used together allows dripping grease to drain and be kept away from the high heat of the oven broiler. DO NOT use the broil pan without the insert.
DO NOT cover the broil pan insert with foil. The exposed grease could catch fire.
To set the oven to Broil:

1. Place the broiler pan insert on the broiler pan. Then place the food on the broiler pan insert.
2. Arrange the interior oven rack and place the broiler pan on the rack. Be sure to center the broiler pan and position directly under the broil burner. If preheating the broil burner first, position the broiler pan after the broil burner is preheated.
3. Turn selector knob to Broil.

The oven indicator light will remain on until the selector knob is turned to the off position or the temperature control cycles off.

Choose a suitable shelf position. To ensure that meat is cooked through rather than just browned on the outside, broil thick pieces of meat and poultry on shelf positions 2 or 3. Use shelf position 4 for thinner items that need less cooking time like steaks, chops, or hamburger patties.
When finishing off meals by browning the top under the broiler, use metal or glass-ceramic bakeware. Do not use heatproof glass or earthenware, as these cannot withstand the intense heat of the broiler. Center the item in the oven, so that it is directly under the broiler.

Griddle Operation

Before Using the Griddle

1. Clean the griddle thoroughly with warm, soapy water to remove dust or any protective coating.

2. Rinse with clean water and wipe dry with soft, clean, lint-free cloth.

3. Use the included stainless-steel cover for the griddle when not in use.
   The cover must be removed before turning the griddle on.

4. 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 10-12 minutes.
3. When the griddle is preheated to the desired temperature, the indicator light will turn on.
4. Butter or cooking oil may be added.

CAUTION
✓ The surface of the griddle is hot after use. Please allow sufficient time for the griddle to cool prior to cleaning.
✓ When using the appliance for the first time, the oven and broiler burners should be turned on to burn off the manufacturing oils. Turn the oven on to 450°F (230°C) for 20 to 30 minutes; after that, turn the oven control knob to “Broil” for the same length of time. It is recommended to turn on the ventilator above the range at this time.
✓ Must disconnect the electrical supply before servicing or cleaning the appliance. Failure to follow this advice may result in injury or death.
