LP GAS AND CYLINDER INFORMATION
Your new gas griddle operates on LP (Liquified Petroleum) Gas. It is odorless, colorless, and non-toxic when produced.
You can smell LP gas as it has been given an odor similar to rotten eggs, for your safety.
The LP cylinder used with your griddle must have two features:
- An OPD (Overfill Protection Device) that prevents accidental gas leaks caused by overfilling of the cylinder. Each cylinder contains a float that closes the input value when the cylinder is 80% full. This allows room or the propane gas to expand in hot temperatures. A triangular hand wheel distinguishes this type of cylinder.
- An QCC1 Type1 Quick Connect Valve that provides fast cylinder hook-ups and requires only to be tightened by hand.

TRANSPORTATION AND STORAGE
- The LP cylinder must include a collar to protect the gas supply valve.
- Do not store a spare LP cylinder under or near the griddle.
- Never fill the LP cylinder beyond 80% capacity.
- If the warnings 2 and 3 above are not heeded exactly, a fire causing death or serious injury may occur.
- Always transport in an upright position.
- Do not smoke when transporting your LP cylinder.
- Place a dust cap on the cylinder gas valve outlet whenever the cylinder is not in use. Use only the type of dust cap that is provided with the cylinder valve when purchased. Other types of cap or plugs may result in leakage of propane.
CYLINDER SPECIFICATIONS
- Cylinder purchased or exchanged for your gas griddle must be manufactured and marked in accordance with the specifications for LP Gas cylinder of the U.S. Department of Transportation (DOT) or the National Standard of Canada, CAN/CSA-8339, Cylinders, Spheres and Tubes for Transportation of Dangerous Goods and Commission, be equipped with a listed over-filling prevention device (OPD), and be equipped with a cylinder connection device compatible with connection for outdoor cooking appliances.

A frosty cylinder valve indicates possible gas overfill. Close the LP valve and call your LP dealer immediately.
|
CONNECTING REGULATOR TO LP CYLINDER
![]() |
| Only use the gas pressure regulator provided with this outdoor cooking appliance. This regulator is set for an outlet pressure of 11 inches water column. |
Your regulator is equipped with a QCC Type 1 quick connect system. It does not allow gas to flow until a positive seal has been made. It has a thermal element that will shut off the gas flow if the temperature reaches 115 °C (240 °F). It also has a flow-limiting device that restricts the flow of gas to 0.28 cubic metrics per hour (10 cubic feet per hour).

Each griddle burner is tested and calibrated at the factory prior to shipment; however, variations in the local gas supply may make it necessary to adjust the burners. Please visually check the flames of the burners. Always visually inspect your griddle before lighting. Replace any hose that is frayed or cracked. Look for anything that could block ventilation and remove such a blockage or move the griddle. After lighting, check the flame pattern to ensure you have even heat distribution for each burner. If burners don’t light up, or if the flame pattern is uneven, see the Troubleshooting section.

LIGHTING THE MAIN BURNERS USING ELECTRONIC IGNITION

- Turn ALL control knobs to OFF position.
- Turn gas supply on at LP cylinder valve or at regulator.
- Push in control knob and turn it anti-clockwise to HI position. Push and hold ignitor button to light the burner.
- If the burner does not ignite, turn control knob to OFF position, wait for 5 minutes before attempting to relight the burner.
- If the burner ignites, repeat for other burners, and turn the control knobs to the temperature setting required for your food.
* Should the burner still fail to ignite, check the gas supply.
MANUALLY LIGHTING THE BURNERS WITH MATCH STICK
- Turn ALL control knobs to OFF position.
- Turn gas supply on at LP cylinder valve or at regulator.
- Put a match in the match holder. Match holder is attached to side panel.
- Place the lit match through the match lighting hole on side panel. Make sure the lit match is close to the burner ports.
- Push in control knob and turn it anti-clockwise to HI position. The burner should light immediately.
- If the burner does not ignite, turn control knob to OFF position, wait for 5 minutes before attempting to relight the burner.
- If the burner ignites, repeat for other burners, and turn control knobs to the temperature setting required for your food.
* Should the burners still fail to ignite, check the gas supply.
TURNING OFF YOUR GRIDDLE
- Turn off the gas supply at the LP cylinder by turning the valve clockwise to a full stop.
- Turn all burner control knobs to OFF position.
Do not use spirit or petrol for lighting or re-lighting! |
BURNER FLAMES

Always check the burner flame patterns after lighting. A good flame should be primarily blue with a yellow tip and have a minimal amount of flicker. Some yellow tips are OK if they are smaller than 2.5 cm (1 “).
New burners sometimes have oil residue, which will cause yellow flame when burning off. Variations in gas supply, altitude, weather, and other factors can all impact burner performance. Older griddles can also show more yellow flame due to food deposit, oil, and fat buildup.
SEASONING GUIDE
Seasoning your cooking griddle will help create relative non-stick surface for cooking while also protecting it against oxidization. When you receive your griddle it will already have a thin layer of oil applied on the griddle.
That has been done to protect the griddle from rust during shipping and storing, that is normal.
First Seasoning:
- Wash off the shipping oil by using soapy water and a towel or paper towels. Rinse off the soap and air dry.
- Next, apply some virgin olive oil or other vegetable oil on the griddle surface. Using a paper towel to rub a thin coat of oil on the entire surface of the griddle.
- Turn on your griddle at medium-high heat. The oil will eventually begin to smoke which is good. Leave it heating until the smoke stops. Turn off your griddle.
- Let the surface cool down and repeat above process for 2-3 times until you get a nice black surface on the griddle. Once you’ve completed this process, you’ll have a perfect grilling surface to get cooking on! Use long-handled barbecue utensils and oven mitts to avoid burns and splatters. Proceed to “PREHEATING”.
*After you are done using your griddle you should apply a very thin coat of cooking oil to maintain your seasoning bond and protect it from rust.
PREHEATING
It is necessary to preheat the griddle before cooking, depending on the type of food and the cooking temperature.
Preheat the gas griddle on MEDIUM/HIGH for 5 to 10 minutes. Reduce heat as appropriate for what you are grilling. Next, brush or spray the cooking griddle to prevent food from sticking.
Cleaning and Maintenance
Your new griddle has been designed and manufactured to high quality standards. It will provide you with many years of fun grilling time, however, it requires a minimal amount of maintenance.
Clean griddle often, preferably after each cookout. If a bristle brush is used to clean any of the griddle cooking surfaces, ensure no loose bristles remain on cooking surfaces prior to grilling.
|
Grease is flammable. Let hot grease cool down before attempting to handle it. Avoid letting grease deposits collect in the bottom of the firebox.
COOKING GRIDDLE
Most foods can be cleaned up by scraping and wiping down the cooking griddle with a paper towel or wet soft cloth.
To remove tough food residue, you can use a mild cream cleaner and pad. You can also use soapy water or a paper towel and 1/4 cup of table salt as another method to clean your griddle. Rinse well and dry it.
STAINLESS STEEL
Clean with multipurpose, low-abrasion, non-phosphorous metal or stainless steel polish and a soft cloth. Always polish in the direction of the finish. Do not allow grease and dirt to accumulate. In addition, several products and naturally occurring substances can damage all stainless-steel finishes. These include, but are not limited to, swimming pool chemicals (chlorine and bromine), lawn and garden fertilizers, ice-melting products, sea or other salt water, urine, bird droppings, and tree sap. Upon contact with these substances, immediately wash and dry the stainless-steel surface and be careful to avoid burns.
OTHER EXTERIOR SURFACES
Wash with a mild dishwashing detergent and warm water. You can use a cloth, soft brush (non-metallic), or plastic cleaning pad. Rinse thoroughly and wipe dry.
GREASE CUP
Check after each use. Remove and empty the grease cup when half full. It can be washed with warm water and mild dishwashing detergent.
BURNERS
We recommend you clean your burners at least twice a year, or before use if the griddle has not been used in over one month.
| Small insects and spiders may enter the burner tubes. Sometimes they will build nests or spin webs that can block or reduce the amount of gas flowing through the burner. You will usually see a smaller flame, or a flame that is mostly yellow rather than blue, coming from the burner when this happens. Other signs include the griddle generating uneven or low heat, or difficulty in igniting the burners. In cases of severe blockage, this can cause the flame to burn backwards, and outside of the burner tubes, which can damage your griddle and/or cause personal injury. IMMEDIATELY SHUT OFF THE FLOW OF PROPANE GAS AT THE CYLINDER BY TURNING THE HAND WHEEL CLOCKWISE SHOULD THIS HAPPEN. Wait for the griddle to cool down and then clean all burners. |
CLEANING THE BURNERS
- Ensure the gas is turned off at the LP cylinder.
- Remove the cooking griddle.
- Lift each burner up and out.
- Clean the inside of the burner using a stiff wire. A straightened coat hanger will work.
An alternative is to use compressed air. Always wear protective gear for your eyes when using this method.
Never enlarge the burner ports during cleaning. - Brush the outer surface of the burner.
- Ensure all ports (holes) are free of debris.
- Inspect the burners. Replace any that have cracks or enlarged ports.
- Replace the cooking griddle.
- Perform the Leak Test described earlier in this Owner’s Manual.
|
GRIDDLE STORAGE
- Clean your griddle before storage. Store at a cool dry place.
- Storage of a gas griddle indoors is permissible only if the LP cylinder is disconnected and removed from the gas griddle.
- A cover is highly recommended to protect your griddle. Choose from a variety of griddle covers offered by the manufacturers.
- Perform a Leak Test before using the griddle after it has been kept in storage for some time.
