Six main burners, one side burner, one special edition
The “6+1” in the name counts the burners: six under the lid, one in the right-hand side table. Nexgrill itself lists the grill as “Deluxe Gasgrill mit 6 Brennern und Seitenkochfeld” (Deluxe gas grill with 6 burners and side burner) and calls it a special edition in matt black. The manufacturer’s page and the Amazon catalogue carry the same model number, 720-0898F. There is no second colour or version in Nexgrill’s German range.
The manufacturer named in the operating manual is Global Leisure Group Deutschland GmbH of Paderborn. The grill is built in China, which is also stated in the manual, on the last page.
On 21.10.2026 no Amazon warehouse offered it on Amazon, only marketplace sellers. The lowest new price was approx. €599 (the seller was Nexgrill Deutschland on the marketplace; our price box had previously listed around €420). All price figures for this grill in this review refer to this marketplace price, not to a price from Amazon itself.
Of the four grills in our table further down, it is therefore the most expensive. You can find the other gas grills in our catalogue in the Gas grills category.
What is fitted, according to the manual and parts list
The six main burners are made of stainless steel. Nexgrill has mounted them at the sides so that dripping fat and dirt clog them as little as possible. Above each burner sits a stainless steel flame tamer that radiates the heat upwards, so the grill needs no lava stones. The manual uses three names for this part: Flammenabweiser in the text, Flammenverteiler in the parts list, Flammenbändiger in the warranty. In our understanding it is the same component above the burner each time, six in total.
On top go three cast iron cooking grates and above them a warming rack. Whether the grates are coated is answered differently by the sources. Amazon writes of porcelain-coated cast iron grates, while Nexgrill on its own page only mentions cast iron.
The figures for the cooking area also contradict each other. The data table on the manufacturer’s page gives 85.7 × 43.8 cm, the descriptive text below it rounds to 85 × 43 cm, and Amazon lists 82 × 43 cm. We go with the manufacturer’s table. That works out at a good 3,750 cm² of grate, not counting the warming rack.
The side burner is also made of stainless steel and has its own hob, its own control knob and a lid. In the product photo it sits on the right, with a plain shelf on the left. Ignition is electronic: a pulse ignition module with its own button sends the spark through a separate ignition cable to each main burner, and a 1.5 V AA battery is included. A temperature gauge is set in the middle of the lid.
At the bottom the cart has a cabinet with two doors, handles and door magnets. Behind the left door sits the regulator and hose unit, and the parts list also includes a holder for the gas cylinder there. In addition there are six utensil hooks, plus a drip tray and grease cup.
For the casters, Amazon and the manual do not agree. Amazon writes of four wheels, two of them lockable. The parts list counts one swivel caster with a lock, one swivel caster without, and two fixed casters. We rely on the parts list, but check it on delivery anyway. We only know the outer dimensions from Amazon: 147.6 × 62.0 × 118.3 cm (length, width, height).
What Nexgrill states neither on the product page nor in the manual: the weight, its own outer dimensions, the area of the warming rack, a maximum temperature, the material of the lid, body and frame (only Amazon mentions the stainless steel frame), the consumption of individual burners and an assembly time.
In detail: where the three kW figures come from
Our title lists 18.6 kW because that is the figure from the Amazon catalogue. The manual arrives at 20.08 kW, the manufacturer’s page at 21.1 kW. That sounds sloppy, but two of the three values can be explained.
The 20.08 kW in the manual is the sum of all burners. According to the manual each main burner has a rated output of 2.93 kW, six of them make 17.58 kW, and the side burner adds 2.5 kW. The small abbreviation next to the figure matters: Hs. It stands for the gross calorific value, meaning the energy in the gas including the heat held in the water vapour of the exhaust gases. A grill does not use this condensation heat; it goes into the air with the steam. The net calorific value Hi leaves it out and is around 8 percent lower for propane.
The manual gives the gas consumption of the whole appliance as 1,435 g of propane per hour, and 1,461 g for butane. We recalculated this. With the gross calorific value of propane, around 50.4 MJ per kg, you arrive at 20.1 kW, which is the manual’s figure. With the net calorific value, around 46.4 MJ per kg, it is 18.5 kW. That is very close to Amazon’s 18.6 kW. Whether the Amazon figure arose this way is not stated anywhere, but it would be plausible.
For the 21.1 kW on the manufacturer’s page we found no derivation.
What does this mean for comparison with other grills? A kW figure is only useful if both manufacturers use the same basis and count the same burners. A side burner does not heat a grate. For the area under the lid, the 17.58 kW of the main burners counts on the Deluxe 6+1, which spread over a good 3,750 cm² is around 4.7 watts per square centimetre. Even this figure says only a limited amount about cooking results, because how much heat reaches the grate depends on the lid, the flame tamers and the mass of the cast iron grates.
Can you grill indirectly on the Deluxe 6+1?
Yes. The manual explicitly describes indirect cooking: the food sits on one side, the burners run on the other. With six individually adjustable main burners you can make the hot zone wider or narrower, burner by burner.
The usual split on a wide grill like this: three burners on, three off, with the roast over the cold ones. Equally common is to heat the outer left and right and place the food in the middle, so the heat comes from two sides. That is general grilling technique, not a Nexgrill specification. How the principle works and which zone suits which food is explained in our guide on direct and indirect heat.
Two caveats belong here. A lid gauge always measures the air at the top under the hood, not the temperature at grate level next to the meat, and for a roast the core temperature is what counts anyway. The parts list includes no probe thermometer. Second, everything that more expensive six-burner grills have fitted for special tasks is missing: the parts list includes neither an infrared rear burner nor a sear zone nor a rotisserie. Rotisserie and infrared burner do appear in the manual’s troubleshooting section, but after comparison with the parts list that is a text block from other models.
Gas connection, leak check, lighting
The grill is designed for liquefied gas, and according to the manual you must not use natural gas. In Germany the appliance category I3B/P at 50 mbar applies. Nexgrill requires you to use only the supplied pressure regulator and the supplied hose. Replacement regulators and hoses must comply with EN 16129:2013 and the national regulation (these standards apply in the EU), and the hose may be at most 1.50 m long and should comply with EN 16436-1:2014+A3:2020. When connecting it, it must touch neither the drip tray nor the grill head and must not be twisted.
Before every use you check the regulator and hose unit for cracks, abrasion and wear. The manual requires the leak check in full at the installation site, even though the factory has already done it, and again after every cylinder change and before every use. The procedure: all valves off, gas on at the cylinder, then a soap solution of one part liquid detergent and one part water, applied with a spray bottle, brush or cloth to all connections up to the manifold. Bubbles show a leak. Then switch off the gas supply immediately and tighten the leaking fitting; if the leak remains, customer service is next. Do not smoke while doing this, and never look for leaks with an open flame.
To light it, all knobs are set to off, then you open the gas at the cylinder. You push in the burner knob and turn it to the lightning symbol while holding the ignition button down, keeping your face and body as far from the burner as possible. If it does not light immediately, turn back to the circle, the symbol for off, and wait five minutes for the gas to disperse. The flame should be blue and about 2.5 cm high; a slight yellow tip is normal with propane according to Nexgrill.
Where the grill may stand, and where not
The Amazon text says the grill is “ideal for balcony and outdoor areas”. The manual words its location requirements much more narrowly:
- At least 1 m clearance between the front of the hood, the sides and the back of the grill and combustible structures.
- Also 1 m clearance below the cooking surface, and no setting up under covered, combustible structures.
- 3 m clearance from objects that can catch fire and from ignition sources such as the pilot lights of water heaters.
- A location with as little exposure as possible to wind and traffic routes, away from draughty areas.
- The air paths to the burner and the ventilation stay clear.
On top of that comes the principle from the safety instructions: outdoors only, not in buildings, garages or other enclosed areas.
Our assessment: on a concrete balcony without wood cladding, awning or wooden ceiling this can work if it is large. According to Amazon the grill itself is almost 1.5 m long, and the 3 m to anything that can catch fire includes seat cushions, plastic planters and a parasol. On a typical rented balcony it gets tight. In general, what your tenancy agreement and house rules say also applies.
You must not move the grill while it is running. After disconnecting the cylinder, the body should cool for at least 30 minutes before you move it.
Cleaning, care and what the warranty covers
In capital letters, Nexgrill requires you to clean the grill before every use to avoid grease build-up and therefore grease fires. According to the manual you clean the grates straight after grilling while they are still hot: dip a brass-bristle grill brush in water, scrub, and wear grill gloves. Once cooled it is harder. The old version of this review recommended the opposite.
For the stainless steel parts the gentlest method applies, along the grain, and no steel wool because it scratches the surface; for scratches the manual names sandpaper of grit 100. You clean the burners with the gas supply closed, knobs off and the grill cooled, using a wire brush and metal scraper, and clear blocked openings with a straightened paper clip. Wooden toothpicks are expressly forbidden. You empty the drip tray often and wipe it out with a mild cleaner and warm water. According to the manual, some sand on the bottom of the tray is possible.
One point that is easily overlooked on gas grills: spiders. Nexgrill requires the burner tubes to be cleaned before assembly, at least once a month in late summer and early autumn and after long periods of standing. The burners themselves should be inspected at least once a year, and immediately if there is a smell of gas and the flames are yellow, the temperature stays too low, the grill heats unevenly or a popping sound is heard. According to Nexgrill, replacing a burner should be done by a trained technician.
If grease catches fire, you turn off the gas at the source, switch off the burners and keep the lid closed until the fire has gone out.
The warranty is on page 29 of the manual, tiered by component. The tube burners have a 5 year limited warranty against perforation, meaning rust-through. Cooking grates and flame tamers have 1 year, and drops, chipping and scratches are excluded. Stainless steel parts have 1 year against perforation, and all other parts (valves, frame, body, cart, control panel, igniter, regulator, hoses) likewise 1 year. It does not cover scratches, dents, corrosion, heat discolouration and surface rust. It applies only to the original buyer, is not transferable, requires proof of purchase and private use, and you pay the shipping costs. One sentence that was left in the German version stands out: the limited warranty is said to apply only in the United Kingdom. We think this is a leftover from translation, but would have Nexgrill confirm it before buying. The seller’s statutory warranty rights are not affected by this.
What else is worth considering?
| Model | The difference | Price | Our rating | Choose this one if |
|---|---|---|---|---|
| Nexgrill Deluxe 6+1 (this one) | 6 main burners plus side burner, 3 cast iron grates | approx. €599 (marketplace sellers) | 8.0 | you grill for many people and want a wide surface with many zones |
| Weber Spirit II E-310 | 3 burners, less area, longer warranty depending on component | approx. €459.99 | 9.2 | you rarely grill for more than one family and care more about the warranty than the number of zones |
| Enders Hyde 6 SIKR Turbo | also 6 main burners and a side burner, plus turbo zones and an infrared back burner | approx. €539 | 8.6 | you want to sear hard or cook on a spit and are willing to spend more for it |
| Nexgrill Gourmet Pro 4 | 4 instead of 6 main burners, but a cast iron griddle plate in the main grill | approx. €449 | 8.3 | you want to stay with Nexgrill and need a plancha surface next to the grate |
The prices of the other models are guide values from our price boxes as of September 2026 and often change on Amazon; the price of the Deluxe 6+1 is the marketplace price from 21.10.2026. The rating is our editorial assessment of the available data; we did not measure anything on any of these grills.
The Weber Spirit II E-310 (approx. €459.99) has the highest rating of the four in our comparison and, according to Weber, a longer warranty depending on the component. The Enders Hyde (approx. €539) brings zones that the Nexgrill does not have.
When the Deluxe 6+1 fits and when another one does
The surface area is the strongest argument. In our assessment, three cast iron grates on a good 85 cm of width are enough for get-togethers where sausages, vegetables and steaks should all be on at once, without you grilling in shifts. If you mostly grill for two to four people, you heat a lot of surface you do not need with six burners. In that case a three-burner grill like the Weber is the more sensible choice.
The location decides first. A garden or terrace with some distance from a wooden house wall is the place the manual’s clearance rules were written for. A small balcony is not, whatever the Amazon text promises. Also expect to park the grill on a single lockable caster, if the parts list is right. On sloping paved areas we would secure it with wedges.
The side burner is for anyone who cooks sauces, potatoes or a pan of onions at the grill alongside the grate. If you never do that, you are paying for a seventh burner and a second gas line that just need maintaining.
For the budget, on top of the grill price come a gas cylinder, if you do not have one, and a cover. We found no suitable cover with an article number for this model, so you will have to buy by dimensions.
For people who value a long manufacturer warranty, the Deluxe 6+1 is the wrong choice. One year on body, valves and igniter is little for a device of this size, and anyone who has to replace cast iron grates after the second summer pays for them themselves. Anyone who prefers hard-seared steaks with a crust is also better served by an infrared or turbo zone, like the one the Enders Hyde has. If, on the other hand, you are looking for a lot of surface and can live with the warranty package, the Deluxe 6+1 gives you six main burners and a side burner; whether the marketplace price of approx. €599 is worth it compared with the Hyde at approx. €539 is best seen by comparing the two table rows directly.
