• Maintain ALL labels on this product. If any of them comes loose or becomes illegible, replace it before further use.

Grease Fires

DANGER!
Performed properly, frying is a fast and easy way to produce a wide range of delicious food time after time after time. However, there is always the potential of the superheated oil, shortening, or fat to cause a grease fire and the instinctive responses of many people—to use water or to move the fire—can greatly worsen the fire’s damage and the risk of injury.

• ALWAYS have a safe work area and ALWAYS be prepared. ALWAYS train EVERY operator on how to most safely handle a grease fire so they are prepared if one occurs. Consult with your local fire department or police department to see if professional  training is available in your area.
• NEVER use water on an oil fire.
• NEVER use wet towels or other objects on an oil fire.
• NEVER move the fire or splash the burning oil.
• DO warn everyone nearby of the danger. They should evacuate the area in any orderly way.
• DO remove ANY source of heat. Unplug ANY heating element or turn off its circuit breaker.
• DO stop providing additional air. Turn off ANY exhaust hood or fan or turn off its circuit breaker.
• DO cut off the fire’s access to oxygen IF you can do so safely. Cover the tank with its lid or any similar large metal covering, but DO NOT throw anything in a way that might cause burning oil to splash. (ONLY use a fire blanket for this purpose if it is specifically rated to safely handle grease fires. Many are not.)
• DO use your fire extinguisher IF the fire is NOT yet contained under a cover. If it is contained, allow time for it to die out but keep the extinguisher ready. If you need to use your fire extinguisher, use it from a safe distance and be careful that its pressure does NOT cause the burning oil to splash.

Baking soda or salt can be also used to stop small fires or nearly contained fires but NEVER apply either one in a way that might splash the burning oil. NEVER use flour or other fine powders. Despite their similar appearance, most of them ARE highly  flammable at the oil’s temperature and will only worsen the fire.

Installation

General Instructions

1. Unpack the packaging crate of your griddle carefully and properly. Be cautious NOT to drill or saw deep into the crate, which may cause damage to the external surface of this griddle. Exercise caution if loosening any fasteners with a hammer. After the crate is opened or disassembled, inspect the griddle and all its accessories for wear and damage, asking for replacements or repair if needed.
   NEVER use the griddle if any of its components are broken or damaged.
   DO NOT let children or pets play with any packaging without close and constant supervision.

2. Adjust the length of each support leg. While holding its upper part, turn the lower part clockwise or counterclockwise until your preferred length is reached.

3. Use one or more persons to raise and hold one of the griddle’s bottom corners. Screw one support leg onto the hole at this corner using its threaded top bolt. Install the other legs in the same fashion, ensuring that the griddle stands level. (To test this, a spirit level is recommended.)

4. Move the griddle to your platform with care, being sure it remains in its level position.

5. Unscrew the cap of the griddle’s gas inlet, which is located at the lower left corner on its back.

6. Pull the blue caps out of the gas regulator’s inlet and outlet.

7. Position the gas regulator against the griddle’s gas inlet using the threading of its outlet (“OUT”).
   Turn the regulator clockwise until it becomes firmly attached.

8. Connect your gas supply line to the regulator’s ¾″ inlet (“IN”) using a compatible fitting. For your safety, install a dedicated pressure gauge (not included) to the gas line.

9. Remove the protective sheet from the cooking plate at the top of the griddle.

10. Slide the collection tray onto its support rails underneath the griddle using its lips.

NG-LPG Settings Conversion
DANGER!
This griddle was preset for natural gas (NG) application at the factory. For use with liquid propane gas (LPG), measures MUST be correctly taken to convert its NG settings to LPG settings before the griddle is connected to its gas regulator and supply. Failure to do so may lead to incorrect fuel-air mixture, which WILL cause incomplete combustion and inefficient energy use, posing a range of safety hazards including gas leaks, fires, and explosions.

Adjusting the Gas Regulator

1. Unscrew the hex cap from the top port of the gas regulator, exposing the NG-LPG conversion adapter with the marked “LP” at the top and “NAT” at the bottom.
2. Unscrew the adapter from the cap, flip its “LP” and “NAT” positions, and screw it back onto the cap.
3. Replace the adapter into the regulator and seal its top port by completely retightening the cap.

Changing the Orifices

1. Pull the burner control knobs away from the griddle. If it is hard to do so, turn the knobs completely counterclockwise and loosen their locking bolts using a Phillips screwdriver (not included) beforehand.
2. Unscrew the four screws from the corners of the griddle’s front panel and then remove this panel, exposing the hex rings of the NG orifices preinstalled at the shafts of the burner control knobs.
3. Loosen the pilot lights’ nuts and unscrew these marked bolts. Then the manifold should come loose.
4. Remove the inner brackets at the left and right sides. Then, pull the manifold until the knob shafts are disconnected from the burner assembly, exposing the NG orifices’ main bodies.
5. Unscrew the No. 37 NG orifices and replace it with the provided No. 51 LPG orifices.
6. Replace the inner brackets and fasten them into place using their locking bolts. For your convenience, use one or more persons to raise and hold the griddle to provide easy access to the lower part of these brackets.
7. Replace the manifold using its locking bolts, pushing until the LPG orifices are firmly seated in their slots on the burner assembly. Retighten the previously loosened locking nuts until the pilot lights become secure.
8. Replace the front panel and secure it in place using its locking screws.
9. Push the removed knobs back onto their shafts, retightening their locking bolts as needed.

Operation

DANGER!
Again, ensure that ALL of the following conditions ARE fulfilled BEFORE using the gas griddle.

• The work area is well-ventilated.
• All gas connections are secure.
• No gas leaks are detected.
• The griddle stands level.
• The protective sheet is fully removed from the cooking plate.
• The drain hole in front of the cooking plate remains hollow.
• The collection tray is already placed under the drain hole.
• All burner control knobs are in their “OFF” positions.
• The pilot lights are uncovered and clean.
• No flammable or explosive materials are placed around.
• A fire extinguisher rated for grease fires is kept nearby.

1. Open the main valve of your gas supply line, allowing gas to flow into the griddle.
   Check the gas pressure gauge if you have already installed one. If it reads higher than the gas regulator’s preset pressures (4″ WC for NG and 10″ WC for LPG), close the main valve I MMED I ATELY. For safe decompression, open the regulator’s pressure relief valve (“VENT”) by unscrewing its yellow cap. Have a certified professional address the issue before continuing work.

2. Ignite a pilot light using a burning match or an electric igniter (not included), ensuring that the initial flame’s height reaches ½ inches (13 mm) or so. If necessary, use a flathead screwdriver (not included) to adjust the pilot valve until an optimal flame is achieved. Repeat this for the other pilot light(s).

3. When the pilot lights are lit, activate the burners by turning their control knobs counterclockwise.
   Then, the flames should grow higher. If they fail, rotate the knobs to “OFF” and turn the pilot valves counterclockwise to boost the initial flames.

4. Adjust each flame using its burner control knob. The further you turn it counterclockwise, the higher the flame should be. To moderate a flame, turn the knob back (clockwise) as needed.

5. Preheat the griddle’s cooking plate as needed. Then, place your oil and food items on the heated plate and use appropriate utensils to cook.
   Exercise caution with ANY heated surfaces. Wear specialized gloves, aprons, and any other necessary PPE during use.
   Pay attention to the collection tray under the drain hole. Dispose of the collected wastes in time to prevent accidental spills, which may lead to property damage and personal injury.

6. When finished with cooking, turn the burner control knobs to “OFF”. Then, the pilot lights should remain lit, serving a constant ignition source for the burners.

7. Close your main gas valve to stop the gas supply to the griddle. The pilot lights should come off.
   After cooking, be cautious of ALL heated surfaces and make sure your ventilation or exhaustion system continues operating to prevent potential health issues.

Maintenance

DANGER!
Ensure that ALL the following precautions are met BEFORE performing cleaning, servicing, and other maintenance for the gas griddle.

• Your gas supply is completely turned off.
• The griddle is already deactivated.
• No gas fumes or leaks exist.
• No inflammables or explosives are placed nearby.
• Proper ventilation remains ensured in the area.
• All surfaces of the griddle have cooled down.
• All proper PPE necessary for your work is put on.

Cleaning the External Surfaces
Clean the cooking plate, splash boards, and all the other external surfaces after each use. Remove any grease, grime, and food residues using a wire brush or grill scraper and wipe off any remaining debris using a soft, damp, and warm cloth or paper towel. If needed, apply food-grade detergent BUT be sure to thoroughly rinse it away with clean water. NEVER use caustic chemicals.

Emptying the Collection Tray
Hold the front lip of the collection tray, slide it away from the griddle, and pour the collected wastes into appropriate containers or permanent facilities, which should comply with local and national codes and regulations. Clean the tray in the fashion above and then dry it completely.

Maintaining the Cooking Plate
After the cooking plate is cleaned and fully dries, it is essential to take proper rust-preventing measures to maintain its good performance and food safety. For this, we strongly recommend the so-called “seasoning” method.

1. Preheat the cooking plate to 300–350°F (150–180°C).
2. Pour a few tablespoons of cooking oil onto the plate, adding more if needed.
3. Use a brush or lint-free cloth to evenly distribute the oil across the entire cooking surface, creating a thin and non-stick protective coating that can guard against moisture and oxygen. Wipe off any excess oil as needed.
4. Repeat Steps 2–3 until the cooking plate has a smooth and mirror-like surface.

Inspecting the Equipment
Check the gas connections and lines for any signs of looseness, wear, damage, and leaks between uses. If necessary, have a certified technician address the issues as soon as possible.
Periodically inspect the gas regulator, pilot lights, burner control knobs, and any other components of the griddle for any signs of damage and malfunction. Repair or replace any problematic parts with new identical ones. If necessary, seek professional assistance from certified technicians.
