11. Burning Off Factory Grease Before First Use
Measures to perform before using the product for the first time.
When burning off the storage grease, the appliance produce unpleasant smoke.
This is normal, the smoke will vanish once the storage grease has been burned out.
After the leak test, the grease used during factory storage must be burned off from the grill before it can be used. 
You can burn off the storage grease by following the instructions below:
1. Open the hood and ignite all burners according to the lighting instructions. 2. Set the burner to “MAX” and let them burn for 5 minutes with hood open. 3. Close the hood and keep the burner at “MAX” for 10 minutes 4. Close the regulator valve and turn off the burner. 5. Let the appliance cool down for 15 minutes. 6. Clean the cooking grids with grill-cleaning brush. 7. Grease the cooking grids with cooking oil.
12. Before Use
To operate the grill safely and appropriately, you need to perform a few checks before each use. 
Carefully go through the checklist below:
1. Check that the grill is place correctly and there are no flammable materials in the immediate vicinity of the grill. 2. Check that the gas hose is not cracked or torn. 3. Check that the regulator is fastened tightly. 4. Check that the grill’s bottom, grease tray, flame tamer and burners are clean of grease and marinade. By doing this, you can prevent grease fires. 5. Checked that the burner holes are not covered by insert or webs. 6. Checked that there are no bristles from grill brushes stuck to the grill or grids.
13. Lighting Instructions Using the Integrated Piezo Igniter
1. Open the hood. 2. Turn on the regulator valve. 3. Ensure all control knobs are in the OFF position.  4. Push down a control knob and turn it anti-clockwise to the ignition position, this will light the burners.  5. Once the first burner is lit, repeat for the others. 6. Adjust flame intensity between MAX and MIN. 7. If ignition fails, turn knob to OFF, wait 5 minutes, and try again. If you cannot get the burner to ignote using the pienzo igniter, you can try lighting the burner up with a long match or lighter.  8. To turn off: close the gas cylinder valve (or regulator switch), then turn all control knobs to OFF.
14. Igniting with a Long Match or Lighter
1. Open the hood of the grill. 2. Turn the regulator valve on. 3. Light a long match (min. 90mm length) 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 centimeter away from the burner. When the first burner has been ignited, you can ignite the remaining burners in order by turning the control knob counter-clockwise between 6. When the first burner has been ignited, you can ignite the remaining burners in order by turning the control knob anti-clockwise between “MAX” and “MIN”.
If the burner does not light up within five seconds, turn the control knob to OFF and try to find a solution from the troubleshooting table. Or contact your retailer/distributor.
15. Checking the Flames
Always check the flame when turning the grill on. The burners have been optimized at the factory, but the small holes on them attract insects to nest and make webs on the burners. 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 from the top down.
16. Preventing Rust
Rust is a chemical process in which iron oxidizes and begins to flake away the metal. This is cause by water that soaks into the metal or comes in contact with the metal frequently over time. As an outdoor appliance made of steel, some appearance of surface rust should be expected from time to time. 
Keeping your grill under cover, clean and dry, goes a long way to preventing rust occurring, some tips are:
1. Ensure cooking surface (including flame tamer) are kept clean and dry after cooking, particularly after cooking with marinades. Cooking surface should be rubbed with oil after use. 2. Do not leave the grill out in the rain. 3. Do not store the grill when wet. Dry thoroughly first. 4. During both summer and winter, periodically remove the cover to enable the grill to air out, and get rid of any built up condensation. 5. Light surface rust may be easily removed with rag, soaked in white vinegar, or using a commercial rust remover. Dry the affected area and apply a coating of rust preventing fluid, available at most auto stores. 6. Chipped enamel can be treated with touch up paint to cover the bare metal surface.
17. Cleaning Cooking Grids
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 such 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 loose food and grease from the surfaces using paper towels, for example. 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 10 minutes. 6. Brush burned food and dirt off with a cleansing brush intended for grills 7. Grease the cleaned grilling grids with cooking oil using e.g., paper towels or a cooking brush.
18. Cleaning Grease Tray
You can make the cleaning easier by using a foil on top of the grease tray to collect any extra food and grease. 
When cleaning the tray, you only need to remove the dirty foil. An unclean grease tray is the most common cause of grease fires. 
The grease tray must not have pools of grease on it.
If you see pieces of food or marinade on the grease tray or cup, you must clean the tray/cup immediately by following the instructions below:
1. Check that the grill is turned off. 2. Take the grease tray/cup out of the grill. 3. Scrape loose food and grease off using the scraper on the grill-cleaning brush or a plastic spatula. 4. Wash the grease tray/cup with mild dishwashing liquid. 5. Dry the grease tray/cup and place it back into the grill.
19. Cleaning Flame Tamers
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 the 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.
20. Cleaning Burner
The grill’s burners are the most vital part for the grill’s functionality 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 to nest in the burners. Such obstructions cause the flame to burn unevenly and impurely. Obstructions may cause the flame to flare up outside the gas pipe, which will damage the grill severely. 
Clean the burners by following the instructions below:
1. Check that the grill is turned off. 2. Remove the grill grids and heat distributor plates. 3. Remove the burner from the fire box by loosening the mounting screw. The screw is normally located at the back end of the burners. 4. In some grill models, removing the burners requires that you also remove the back plates of the grill. 5. Some models can also be cleaned even when the burners are in place. The most important part is being able to access all of the small gas holes. 6. Use the brass cleaning brush intended for grills to clean the burner surfaces. 7. Ensure that the burner holes are open and clean. You can use a thin wire for this. 8. If the burner is damaged or 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.
21. Cleaning Other Grill Components
Chloride and salt may cause 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 the 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 dry the cleaned parts 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 of 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 on an unnoticeable spot.
22. Storage
Check these instructions if you stop using the grill for a longer time or 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 the 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 steel parts dry off. 3. Let the grill cool down. 4. Ensure that all grill grids are greased. 5. If storing the grill outdoors, 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 into newspapers or similar so that the surfaces do not get scratched. 6. Remove the low-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 covers it all the way down. Ensure that air can circulate even under the cover.
