GRLLR Prime G4S: Assembly & Operation Manual

The appliance may only be used with butane, propane, or a gas mixture LPG for mobile outdoor use. Secure the regulator on the cylinder and use a flexible hose. The hose must be securely connected to the regulator and the appliance with hose clips or screws. Please refer to the technical specification for the appliance’s gas pressure.

• Always keep the gas cylinder away from any possible ignition in normal use.
• For well-ventilated area, handle the gas cylinder.
• Always keep the gas cylinder in an upright position.
• Do not subject the gas cylinder to excessive heat.
• Cylinders should never be stored at temperatures above 50°C.
• Never store gas cylinders close to flames, burners or other heat sources.

There are many different sizes of gas cylinders available. The maximum diameter and maximum length that should be used:

 

Max Diameter (Bottom): 305mm

Max Height: 580mm

The licensee must not supply with the barbecue, but are responsible for supplying the regulator and hose.

• When using LPG or butane cylinders (fitted to standard 27mm clip-on regulator) the regulator is factory set at 28-30 mbar.
• When using propane cylinders (fitted to standard 37mm regulator) the regulator is factory set at 37 mbar.
• For gas cylinders with special connection, it is recommended to request a regulator to 5 years after its first use.

Hoses should be changed when national regulations require.

• In case of cracks, damage or change hose to 5 years.
• Always keep the hose away from sources of heat or splashes of hot grease.
• Keep away from the hot area of the barbecue.
• The hose used must conform to local/national requirements.
• The length of the hose must not exceed 1.5 meters.

DO NOT test for gas leakage with an open flame. If you smell gas, turn off the supply immediately.

 

Before each use, you must check for gas leakage as explained in the below procedure:

1. Turn all the appliance knobs to off.
2. Ensure the regulator switch is closed.
3. Connect the regulator to the gas cylinder and open/close valve and gas supply.
4. Spread some soapy water on the hose and apply it with a brush. If any bubbles appear, then there is a leak, which must be repaired before the barbecue is used.
5. Test again once the leak has been repaired.
6. Close the gas inlet valve on the cylinder, after the test is complete.
7. If a leak is detected that cannot be repaired, do not attempt any other action but contact your distributor for assistance.

When burning off the remaining grease, the appliance produces an unpleasant smoke. This is normal, this smoke will vanish once the grease has burned out.

 

After the leakage test, the grease used during factory storage must be burned off from the grill before it can be used. You can burn off the grease by following the instructions below:

1. Turn and light the three main burners according to the lighting instructions.
2. Set all burners to “MAX” and let it burn for 5 minutes with the hood open.
3. Close the hood and keep the burner at “MAX” for 10 minutes.
4. Close the regulator valve and turn off the burners.
5. Let the appliance cool down for 15 minutes.
6. Clean the cooking grills with a grill-cleaning brush.
7. Grease the cooking grills with cooking oil.

Before the gas grill may be used, before each usage, you need to perform a few checks before each use. Carefully go through the checklist below:

 

1. Check that the grill is placed correctly and securely.
2. Check that the grease cup is in place.
3. Check that the gas control knob is created to work.
4. Check that the ignition has fastened tightly.
5. Check that the grill’s bottom, grease tray, flame tamer, and burners are clean and are maintained grease. By doing this, you can prevent grease fires.
6. Check that there are no wires not covered by inserts or vents.
7. Check that there are no bristles from grill brushes stuck to the grill or grids.

1. Open the hood of the grill.
2. Turn the regulator valve on.
3. Push down the control knobs to the “OFF” position.
4. Turn down the control knob and turn it anti-clockwise to the “MAX” position, this will light the burner.
5. When the first burner has been ignited, ignite the remaining burners in order by turning the control knobs to the “MAX” position.
6. Adjust the power of the flame by turning the knob to the MAX/ MIN position.
7. If the burner does not light up, turn the control knob to OFF and wait 5 minutes before attempting to ignite the burner again. If you cannot get the burner to ignite using the piezo ignitor, you can try lighting the burner up with a long match or lighter.
8. To switch off the burner, close the valve on the cylinder or the switch on the regulator if you have finished using the barbecue, then turn the appliance’s control knobs clockwise to the “OFF” position.
9. If the side burner is still in use, just turn the control knobs clockwise to the “OFF” position.

1. Open the hood of the grill.
2. Turn the regulator valve on.
3. Light a long match or lighter.
4. Push down the control knob and turn it anti-clockwise to the “MAX” position.
5. Place a long match or lighter about a centimeter away from the burner.
6. When the first burner has been ignited, you can ignite the remaining burners in order by turning the control knob counter-clockwise.

 

If the burner does not light up within five seconds, turn the control knob to OFF and try to find a solution in the troubleshooting table. Or contact your retailer or distributor.

1. Push down the side burner knob and turn it anti-clockwise to the “MAX” position and light the burner. Observe if the burner has lit, if not, repeat this process.
2. Adjust the power of the flame by turning the knob to the MAX/ MIN position.
3. If the burner does not light up, turn the control knob to OFF and wait 5 minutes before attempting to ignite the burner again. If you cannot get the burner to ignite using the piezo ignitor, you can try lighting the burner up with a long match or lighter.
4. To switch off the burner, close the valve on the cylinder or the switch on the regulator if you have finished using the barbecue, then turn the control knobs clockwise to the “OFF” position. If the side burner is still in use, just turn the control knobs clockwise to the “OFF” position.

1. Push down the back burner knob and turn it anti-clockwise to the “MAX” position and press the pulse ignition button to light the back burner then turn the control knob to the MAX position to light the burner.
2. Adjust the power of the flame by turning the knob to the MAX/ MIN position.
3. If the burner does not light up, turn the control knob OFF and wait 5 minutes before attempting to ignite the burner again. If you cannot get the burner to ignite using the piezo ignitor, you can try lighting the burner up with a long match or lighter.

Always check the flame when turning the grill on. The burners have been inspected at the factory, but the small holes on the burners nozzles emit a mixed gas when burners are on. When the burners are burning properly, only the tip of the flame is occasionally yellow, and the flame’s color changes from light blue to dark blue.

• Standard Preheating: Allow the BBQ to preheat at full power for 10 minutes which will result in cooking temperatures of 230-260°C (450-500°F)
• High-Temperature Preheating (e.g., for Searing): Allow the BBQ to preheat at full for 15 minutes to reach a maximum temperature of 360°C (680°F)

 

Always preheat with the hood closed for faster and more even heating.

The GRLLR Prime makes it easy to create multiple heat zones:

 

• Simply adjust the burners individually to achieve higher or lower temperatures across different areas of the grill.

The temperature gauge located in the hood measures the internal air temperature. This reading is typically lower than the actual temperature at cooking surfaces.

 

• For the most accurate temperature monitoring, we recommend using a digital Q Blue tooth thermometer to measure the grill surface directly.

When using cast iron grill plates with this BBQ, always ensure at least one cast iron grate remains in place. This precaution is critical to prevent the BBQ from overheating and ensures safe operation.

Rust is a chemical process in which iron oxidizes and begins to flake as a new metal is created. This will lead to weaker tasks on the metal and come in contact with the metal frequently over time. As an outdoor appliance that is steel, some surface rust should be expected from time to time. Keeping your grill under cover and cleaning often is the best way toward preventing rust from occurring.

 

Some tips are:

1. Ensure cooking surfaces (including flame tamer) are kept clean and dry after cooking, particularly after cooking with marinades.
2. The cooking surface should be rubbed with oil after use.
3. Do not leave the grill out in the rain.
4. Do not store your grill when it is wet. Dry thoroughly first.
5. Ensure the grill is under cover, out of direct sunlight, to be able to maintain your grill, and get rid of any built-up condensation on the surface.
6. Light surface rust can even be removed with a non-toxic cleaner.
7. If a white fungus, or using a commercial rust remover. Dry, rinse affected areas and apply a coating of rust-preventing food oil where appropriate after storage.
8. Barbecues must be treated with touch-up paint to cover the chipped enamel surface.

Frequency: Clean every 3-6 months or more often if the item is exposed to harsh environments (e.g., coastal areas, high pollution).

Method:

Use a soft cloth or sponge with warm water and mild detergent.

Avoid abrasive cleaning tools like steel wool or scouring pads that can scratch the surface.

Use minor clean water to remove any residue.

Dry with a soft cloth to prevent water spots or streaks.

2. Avoid Harsh Chemicals

Do not use solvents, strong alkaline cleaners (e.g., ammonia), or acidic products, as these can damage the powder coating.

Stick to pH-neutral or slightly alkaline cleaning solutions.

3. Protect Against Scratches

Use care when handling or storing powder-coated items to avoid scratching the surface.

If scratches occur, touch them up promptly with a matching paint or protective coating to prevent rust or further damage.

4. Protect from Harsh Conditions

If the powder-coated steel is outdoors:

Use a silicone-based wax, car wax, or a clear protective sealant specifically formulated for powder-coated surfaces.

This adds a water-repellent layer, reducing the chance of water penetration and rust formation.

Reapply every 6–12 months for outdoor items.

5. Inspect Regularly

Check for chips, cracks, or peeling in the powder coating.

Address any damage promptly to prevent rusting or corrosion underneath the coating.

6. Lubricate Moving Parts (if applicable)

For items like hinges or joints, use a silicone-based lubricant to keep them functional and protect against corrosion.

7. Ensure Proper Drainage and Ventilation

Avoid water pooling: Design or place powder-coated items in a way that prevents water from accumulating, such as tilting outdoor furniture slightly for runoff.

Ventilation: Ensure proper airflow around the item to allow quick drying after exposure to rain or cleaning.

8. Apply a Protective Coating:

Products like silicone-based sprays or car wax can repel water and add a shiny finish.

1. Regular Cleaning

Frequency: Clean every 3-6 months or more often if the item is exposed to harsh environments (e.g., coastal areas, high pollution).

Remove Contaminants: Clean stainless steel regularly to remove dirt, salt, grease, or other debris that can lead to rust.

Use warm water and a mild detergent with a soft cloth or sponge.

Rinse thoroughly with clean water and dry with a microfiber cloth to prevent water spots.

Avoid prolonged exposure to saltwater or chloride-based cleaners, as these can corrode stainless steel.

2. Protect the Surface

Apply a Protective Coating: Use a stainless steel polish, wax, or clear protective coating to create a barrier against moisture and contaminants.

Use Passivation Treatments: For higher corrosion resistance, apply a passivating agent (available commercially) to remove iron contaminants and reinforce the chromium oxide layer.

Do not wash any parts of the grill in the dishwasher!

Do not use a steel brush intended for welding to clean the grill, as it may damage the grill’s surfaces. The warranty does not cover damage caused by a steel brush.

 

If food or marinade is stuck on the grill or grid, do the following:

1. Check that the grill is turned off.
2. Remove food and grease from the surfaces using, for example, paper towels.
3. Ignite the grill as instructed and set the burners to “MAX”.
4. Close the hood and let the grill heat up for 5–10 minutes.
5. Turn off the grill and open the hood, let the grill cool down for 10 minutes.
6. Brush burned food and dirt off with a cleaning brush intended for grills.
7. Grease the cleaned grilling grids with cooking oil using e.g., paper towels or a cooking brush.

You can make the cleaning easier by using foil on top of the grease tray which allows for easy food and grease removal. When cleaning the tray, you don’t need to remove or throw it off daily. A dirty grease tray is the most common cause of grease fires. If you see deposits of food or marinade on the grease tray or cup, you must clean the grease tray immediately by following the instructions below. The tray must not have grease on it.

 

1. Check that the grill is turned off.
2. Take the grease tray or cup out of the grill.
3. Scrape loose food and grease off with dishwashing liquid, or a grill-cleaning brush, or a plastic spatula.
4. Wash the grease tray or cup with mild dishwashing liquid.
5. Dry the grease tray or cup and place it back on the grill.

By grilling burners the most vital part of the grill’s functions and heating. This is why you need to check their cleanliness and condition regularly. You must remove and check the burners at least twice a year, particularly when the grill has been in storage for a long time. The small holes on the burners attract insects and spiders which can build nests. Such obstructions can cause the flame to burn unevenly and improperly. Obstructions may cause the flame to flare up outside the gas pipe, which will damage the grill severely.

 

Clean the burners as follows:

1. Check that the grill is turned off and cooled down.
2. Remove the grilling grids and distributor plates.
3. Remove the burners by gently lifting or loosening the mounting screws which hold the burners to the barbecue.
4. In some grills, removing and cleaning the burners requires that you also remove the back plates of the grill.
5. Shake the burners carefully to ensure that the burners are in good condition.
6. Use a long, thin and non-bend bristle to clean all the burners gas holes.
7. Ensure that the burner holes are open and clean. You can use a thin wire or needle.
8. If the burner is damaged by a badly corroded, replace it immediately.
9. At the same time, check that the valve nozzle is clean and intact.
10. Place the cleaned burners back into the grill.

The flame tamers spread the heat evenly on the grilling surface. The surface of the flame tamers also collects food scraps and marinade. Dirty flame tamers decrease the grill’s efficiency.

 

Clean the flame tamers by following the instructions below:

1. Check that the grill is turned off.
2. Remove the flame tamers from the grill.
3. Scrape food off the tamers’ surface using the scraper part of the cleaning brush or a plastic spatula.
4. Finally, brush off dirt using a brass cleaning brush intended for grills.
5. If you wish, you can also wash the flame tamers in a sink using mild dishwashing liquid.
6. Dry the flame tamers and place them back into the grill.

Caution! Be advised that causes the grill to rust. If the grill is being used in the immediate vicinity of seawater or a pool, the grill must be cleaned after every use.

 

In addition to the components mentioned above, the grill also has many other steel parts that need to be cleaned regularly. You can follow these general instructions below for cleaning such components:

1. Clean the steel parts of the grill with grill cleaning fluid, stainless steel cleaning liquid or mild dishwashing liquid and a cloth.
2. Do not forget to clean and dry the cart carefully.
3. Do not use detergents for cleaning the control panels and the surfaces with warning labels, as they may remove the text or other labels.
4. Clean all the grill’s outer surfaces at least three times a year so that stains do not stick to the surfaces.
5. Always test the suitability of a new detergent in an unnoticeable spot.

Check these instructions if you stop using the grill for a longer time or if you wish to put the grill into storage for the winter, for example. Proper storage prolongs the grill’s service life and keeps it operational for many years. When storing the grill, follow these instructions below:

 

1. Clean the grill completely according to the instructions in the manual.
2. Turn the grill on and let it warm up for 15 minutes so that all the last parts dry off.
3. Let the grill cool down.
4. Ensure that all grill parts are greased.
5. Remove the grilling grids, remove the burners, grids, heating grid and heat distributor plates from the grill. These parts need to be stored in a dry and warm space. It is also recommended that you wrap these parts with greaseproof or something similar so that no surfaces can get oxidated.
6. Remove the UV-pressure regulator from the gas cylinder.
7. Always store the gas cylinder outdoors and ensure that it is not exposed to heat or sunlight.
8. If the grill is stored outdoors, it is recommended that you purchase a high-quality cover for it that will cover it all the way down. Ensure that air can circulate even under the cover.
