Napoleon P500RSIBNSS-3 Prestige 500 RSIB Natural Gas Grill: Best for infrared cooking variety
- 4 stainless steel main burners
- 500 sq in main cooking area
- Infrared side and rear burners
- Rotisserie kit included
The Prestige 500 combines 4 main burners with infrared side and rear burners. It suits cooks who want searing, rotisserie cooking and regular grilling in one natural gas cart.
Pros
- Infrared side burner
- Infrared rear burner
- Rotisserie kit included
Cons
- Large 66.25 in width
- More features than some buyers need
The Napoleon P500RSIBNSS-3 Prestige 500 RSIB is the best fit for cooks who want several cooking methods from one free-standing cart. It has 4 stainless steel main burners, 500 sq in of main cooking space, a 260 sq in warming rack and a 140 sq in side burner.
Its infrared side burner reaches up to 1,800°F in 30 seconds according to the product details. That gives you a dedicated place for high-heat searing, while the 18,000 BTU infrared rear burner supports rotisserie cooking.
A heavy-duty rotisserie kit is included. The JETFIRE ignition system lights each main burner, and the back channel between burners provides another lighting path.
The cart is 66.25 in wide and 50.25 in high, so measure the hookup area before delivery. You can also compare Weber Genesis natural gas grills.
Its stainless steel construction and natural gas fuel format make it a clear match for a permanent connection, provided the installation is prepared correctly.
Napoleon Rogue PRO 625 5-Burner Natural Gas Grill: Best for large everyday grilling
- 5 main burners
- 625.5 sq in cooking surface
- Infrared side burner
- White LED backlit knobs
The Rogue PRO 625 gives you 5 main burners, a broad cooking surface and an infrared side burner. It fits buyers who regularly cook several foods at once.
Pros
- 5 main burners
- Infrared sear station
- Stainless steel cooking grids
Cons
- 66 in width
- No rotisserie kit listed
The Napoleon Rogue PRO 625 is the better match when your priority is a larger main cooking area and 5 main burners. Its main cooking area measures 34 3/4 by 18 in, and its total cooking surface is 625.5 sq in.
The integrated infrared sear station adds a high-heat zone for steaks and can also handle sauces or side dishes. Stainless steel cooking grids reduce the amount of grate maintenance compared with more delicate surfaces.
White LED backlit knobs make the controls easier to see after dark. The grill also has a stainless steel frame, folding shelf, locking caster wheels and a bottle opener.
This natural gas model is 66 in wide, 25 in deep and 48.5 in high. For a smaller burner layout, compare three burner Weber grills.
Pick it over the Prestige 500 when 5 main burners and a broad main surface matter more than a listed rotisserie kit.
Napoleon Freestyle 425 4-Burner Natural Gas Grill: Best for simpler family grilling
- 4 main burners
- Range side burner
- 571 sq in cooking surface
- JETFIRE ignition
The Freestyle 425 offers 4 main burners, a range side burner and 571 sq in of cooking surface. Confirm the exact natural gas configuration before ordering because the supplied model data also identifies a propane version.
Pros
- 4 main burners
- Range side burner
- Folding shelves
Cons
- Fuel configuration needs careful checking
- No infrared burner listed
The Napoleon Freestyle 425 suits buyers who want 4 main burners and a side burner without the extra features of the premium Napoleon picks. Its cooking surface is 571 sq in, with room for sauces and sides on the side burner.
Stainless steel tube burners provide the main heat, while porcelainized cast iron grids hold heat and create sear marks. The JETFIRE ignition lights each main burner individually, and the ACCUPROBE gauge helps monitor temperature.
That mix suits a household grilling burgers, chicken and vegetables a few times a week. The even burner layout makes it easier to keep one side hotter than the other for indirect finishing.
The supplied model data identifies this version as a propane grill, even though this roundup focuses on natural gas. Check the exact natural gas configuration before ordering, since fuel type matters for a permanent hookup.
Its 52 in width fits more easily than the larger Napoleon carts here. Choose it when footprint and a basic 4-burner layout matter more than infrared side or rear burners.
For care, brush the cast iron grids once they cool enough to handle safely and keep the side burner clear of grease buildup. Wipe stainless steel surfaces with a soft cloth and check the ignition area so debris does not block lighting.
Monument Grills 4+1 Burner Natural Gas Grill: Best for high-heat value
- 50,000 BTU total power
- 630 sq in total grilling area
- Broil zone
- Natural gas hose included
This Monument model provides 630 sq in of total grilling area, 50,000 BTU total power and a natural gas hose. It is a strong alternative when Napoleon branding is not required.
Pros
- Natural gas hose included
- Broil zone
- 630 sq in total area
Cons
- Requires assembly
- Not a Napoleon grill
The Monument Grills M415BZNG is the strongest non-Napoleon alternative for high-heat natural gas cooking. It has 4 main burners, 50,000 BTU total power, a broil zone and 630 sq in of total grilling area.
The main cooking area measures 450 sq in, with another 180 sq in on the warming rack. A natural gas hose is included, and this model supports natural gas only, not liquid propane.
The broil zone uses a U-shaped flame layout and a flame tamer with V-shaped holes. A glass window lets you watch food without lifting the lid, while knob lights and a dual-layer lid add convenience during evening cooks.
That layout suits cooks who like a fast sear at the end of a cook rather than moving food to a separate station. The warming rack helps hold rolls or smaller items while thicker cuts finish below, and the glass window reduces heat loss during quick checks.
The grill measures 55 in wide, 22 in deep and 45.5 in high. It requires some assembly, so allow time to build it before planning your first cookout.
The enamel-coated cast iron grates are meant to limit sticking and spread heat evenly across the surface. Clean the grease funnel and pan regularly, and wipe the non-stick exterior so drips do not bake on between cooks.
Weber Genesis E-415 Gas Grill for Outdoor: Best for broad cooking space
- 4 PureBlu burners
- 820 sq in cooking surface
- Porcelain-enameled cast-iron grates
- Natural gas only
The Genesis E-415 offers 820 sq in of cooking surface with 4 PureBlu burners. Consider it when cooking space matters more than staying with Napoleon.
Pros
- Largest stated cooking area here
- Grease management system
- WEBER CRAFTED compatibility
Cons
- Not a Napoleon grill
- Natural gas only
The Weber Genesis E-415 is a strong alternative when cooking space matters more than the Napoleon name. Its 4 PureBlu burners support an 820 sq in cooking surface, the largest free-standing option in this group.
Porcelain-enameled cast-iron grates retain heat for searing. Weber's FLAVORIZER bars catch and vaporize juices, direct grease away from the burners and work with the pull-out grease tray for cleanup.
The warming rack adds space for keeping food warm, toasting buns or cooking smaller items. The grates also accommodate the WEBER CRAFTED Outdoor Kitchen Collection, including separately sold grillware such as a pizza stone and outdoor griddle.
That extra surface suits larger family meals and casual gatherings where several dishes need to stay at different stages at once. You can sear on the main grates while food rests above and sides stay warm.
This grill is factory built for natural gas only. It measures 64.5 in wide, 27 in deep and 48.1 in high, so compare those dimensions with your hookup area before you commit.
Care is simpler when the pull-out grease tray is emptied before drippings build up. Brush the porcelain-enameled grates gently and inspect the burner ports so food debris does not affect the flame.
SPIRE 36" Built-in 6 Burner Dual Fuel: Best for built-in outdoor kitchens
- 6 main burners
- 1 rear burner
- 904 sq in cooking surface
- 304 stainless steel body
The SPIRE is a built-in dual-fuel grill head with 6 main burners, a rear burner and 904 sq in of total cooking space. It suits a planned outdoor kitchen rather than a free-standing cart.
Pros
- 904 sq in total area
- 6 main burners
- 304 stainless steel body
Cons
- Built-in installation
- Not a Napoleon grill
The SPIRE 36-inch built-in grill is for a planned outdoor kitchen, not a portable cart replacement. It provides 6 main burners, 1 rear burner and 904 sq in of cooking space in a 304 stainless steel body.
Each main burner is rated at 10,000 BTU in the product details. The rear burner adds another cooking option for rotisserie meals or warming dishes, while the stainless steel grates are designed for even heat and easier cleanup.
That burner count suits a household that often cooks several large items at once or wants separate zones for direct heat and gentler cooking. The rear burner gives more flexibility for spit cooking, while the main burners can handle everyday grilling without waiting for one batch to finish.
The dual-fuel format makes fuel planning especially important. Confirm how the exact installation will be configured before building the enclosure, and follow the required clearances and connection instructions.
Its built-in installation type is the main trade-off. Choose it when you are designing an outdoor kitchen around the grill head, not when you need a ready-to-roll natural gas cart.
stainless steel surfaces wipe clean more easily than painted finishes, but they still benefit from regular attention after greasy cooks. Keep the drip areas clear, check the rear burner opening for debris and make sure the enclosure ventilation remains unobstructed.
Napoleon Rogue PRO-S 625 5-Burner Propane Grill: Best propane alternative
- 5 main burners
- Infrared rear burner
- Infrared side burner
- 625.5 sq in cooking surface
The Rogue PRO-S 625 has the same stated cooking-surface size as the natural gas Rogue PRO 625 but uses propane. Choose it only when a permanent natural gas hookup is not your goal.
Pros
- Infrared side burner
- Infrared rear burner
- Stainless steel cooking grids
Cons
- Propane fuel
- Not suitable for a natural gas hookup as supplied
The Napoleon Rogue PRO-S 625 is a useful propane comparison for shoppers who like the Rogue layout but do not have a natural gas connection. It has 5 main burners and a 625.5 sq in cooking surface, matching the stated cooking area of the natural gas Rogue PRO 625.
The PRO-S version adds an infrared rear burner and an infrared side burner. Those zones support rotisserie cooking, high-heat searing, sauces and side dishes, while the stainless steel cooking grids suit regular grilling.
The main difference for this guide is fuel. This is a propane grill, so it is not the right choice for a buyer who has already planned a permanent natural gas hookup.
Choose it only if propane fits your outdoor setup or if you are comparing the two fuel paths before installation. Its 66 in width and 48.5 in height also require the same careful space planning as the natural gas Rogue.
Which Napoleon natural gas grill has the best cooking layout?
The Prestige 500 has the most varied stated cooking layout among the Napoleon natural gas models here. Its 4 main burners handle regular grilling, the infrared side burner handles high-heat searing and the infrared rear burner supports rotisserie cooking.
The Rogue PRO 625 is better if you want 5 main burners and a 625.5 sq in total cooking surface. It also has an infrared side burner, but the listed product data does not include a rotisserie kit.
The Freestyle 425 is simpler. Its 4 main burners, range side burner and 571 sq in cooking surface cover common family meals without adding the infrared features found on the larger Napoleon models.
For a broader brand comparison, read our guide to Napoleon vs Weber gas grills. It helps when you are deciding whether the extra cooking space of a Weber is more useful than staying with Napoleon.
How much space do you need around a natural gas grill?
You need room for the grill's full width, lid movement, side shelves, connection point and safe work access. The Napoleon carts here range from 52 in wide for the Freestyle 425 to 66.25 in wide for the Prestige 500.
That difference matters on a tight patio because side shelves often hold platters and seasonings during a cook. A cart that fits the hookup point may still feel cramped if there is no room to step back safely.
Measure the finished space, not just the opening where the grill will sit. Include cart depth, room to stand in front, lid clearance and access to the natural gas connection.
Think about movement around the sides during a busy cook. Side shelves need clearance for serving dishes, and the connection point should stay reachable for inspection without moving furniture.
The Weber Genesis E-415 measures 64.5 in wide and 27 in deep, while the Rogue PRO 625 measures 66 in wide and 25 in deep. Those small differences can decide whether a grill blocks a walkway.
The Monument Grills model is narrower at 55 in wide and 22 in deep, which may suit a smaller patio better. Even then, leave space in front for safe food handling and opening the lid.
The SPIRE is a built-in grill head, not a cart. Its 40 in width and 21.8 in depth describe the unit, but the enclosure, ventilation, service access and fuel connection need separate planning.
Plan for storage too, with a place for a cover and cleaning tools that does not block the grill. Measure twice before delivery, including height with the lid open.
What should you check before connecting a Napoleon natural gas grill?
First, confirm that the exact model is built for natural gas. The Prestige 500 and Rogue PRO 625 are natural gas models in this guide, while the Rogue PRO-S 625 is propane and the Freestyle 425 data includes a propane configuration.
Do not rely on burner count or a similar name when checking fuel type. Two grills from the same range can look alike while using different fuel systems, and a permanent hookup leaves no room for a guess.
Next, confirm that the branch supply line from the house is properly installed before the grill arrives. Measure the route from the supply line to the planned position and check that fittings and clearances match the manual.
Keep the connection area accessible for inspection. Do not assume a propane model can be converted simply because it shares a brand or burner count with a natural gas model.
Leave room to reach the shutoff and hose connection without moving the grill. That access helps you spot leaks, damage or loose fittings before they become a problem.
Also check hose length and routing. The Prestige 500 lists a 120 inch hose, so confirm the connection point and grill position work together without stress on the line.
Finally, follow the lighting and leak check steps in the manual before the first cook. A careful setup makes the permanent hookup safer for regular use.
How do you clean and maintain a natural gas grill?
Clean the cooking grates after cooking and remove grease from the tray or funnel system before buildup affects the next cook. A brush after the grill cools, followed by a wipe of surrounding surfaces, keeps the cooking area ready.
The Monument model uses enamel-coated cast iron grates and a streamlined grease funnel system. The Weber Genesis E-415 has a pull-out grease tray, while Napoleon models use stainless steel or cast iron surfaces depending on the grill.
Empty the grease container often, wipe drip channels and check that nothing blocks the path from the cookbox to the tray. Inspect stainless steel burners and sear plates for clogged ports as part of routine care.
Cast iron grates need a different touch. Brush them without harsh soaking, dry them after cleaning and avoid leaving water sitting on the surface.
Porcelain-enameled surfaces reward gentle cleaning because the coating protects the metal underneath. Use tools that will not gouge the finish and wipe spills before they bake on.
Inspect burners, openings, the hose and the connection area regularly. Keep the grill covered as appropriate and make sure the cooking area is clear before lighting.
A cover helps limit dust and rain, but it is not a substitute for cleaning. Lift it on dry days and let the grill air out, since trapped moisture can collect underneath.
Check the lid, shelves and casters for loosening after frequent use. If the grill sits unused for a stretch, run a short burn to dry the surfaces, then inspect the ignition system before the next full cook.
Is a Napoleon natural gas grill better than a Weber?
Napoleon is the better fit when you want features such as infrared side or rear burners in a natural gas cart. The Prestige 500 and Rogue PRO 625 both offer infrared cooking zones, while the Freestyle 425 keeps the layout more basic.
Weber is the stronger alternative when you want a larger stated cooking surface. The Genesis E-415 has 820 sq in, compared with 625.5 sq in for the Rogue PRO 625 and 500 sq in of main cooking space for the Prestige 500.
For the larger brand decision, compare Napoleon vs Weber grills after you decide whether you need natural gas, propane or a built-in dual-fuel format.
Final verdict: which is the best Napoleon natural gas grill?
The Napoleon Prestige 500 RSIB is the best Napoleon natural gas grill for buyers who want the broadest cooking range in a free-standing cart. Pick the Rogue PRO 625 for 5 main burners and a larger main cooking area, or the Freestyle 425 for a simpler 4-burner layout.
The Prestige 500 earns that place through variety rather than size alone. Its 4 main burners handle everyday grilling, the infrared side burner gives a dedicated high-heat zone and the infrared rear burner supports rotisserie cooking with the included kit.
That combination suits a cook who sears steaks, roasts on a spit and makes sides on the same grill. It also suits a household that wants one cart to cover several methods without adding separate appliances.
The Rogue PRO 625 is the better pick when main-burner capacity matters most. Its 5 main burners and 625.5 sq in cooking surface make it easier to cook several large items at once, while the infrared side burner covers searing, sauces and sides.
Its stainless steel grids and white LED backlit knobs make evening cooking simpler. The trade-off is the lack of a listed rotisserie kit, so weigh that if you want spit cooking.
The Freestyle 425 is the simpler choice for smaller households or tighter patios. Its 4 main burners, range side burner and 571 sq in surface cover common family meals.
If you are open to other brands, choose the Weber Genesis E-415 for the largest stated cooking surface. Choose the SPIRE only for a built-in outdoor kitchen, and the propane Rogue PRO-S 625 only when a permanent natural gas hookup is not your plan.
The Monument Grills model also deserves a look for high-heat value, with 50,000 BTU total power and a broil zone. Before ordering, match the model to your hookup, patio width and cooking style.

Frequently asked questions
What is the best Napoleon natural gas grill for most people?
The Napoleon Prestige 500 RSIB is the strongest all-around choice here because it has 4 main burners, 500 sq in of main cooking space, an infrared side burner and an infrared rear burner. It also includes a heavy-duty rotisserie kit.
Choose the Rogue PRO 625 if you want 5 main burners and more main cooking space.
Can a propane Napoleon grill use natural gas?
Do not assume a propane Napoleon grill can connect to natural gas. The Rogue PRO-S 625 in this guide is identified as a propane grill, while the natural gas models are specified for natural gas.
Confirm the exact fuel configuration before buying and connect the grill only as directed for that model.
How do I choose a Napoleon grill for a permanent natural gas hookup?
Choose a model identified as natural gas, then check the grill's width, installation type, hose setup and clearance needs. A permanent hookup makes a free-standing cart convenient, but the connection still needs to be planned safely.
Measure the space and confirm the branch supply line before installation.
Is a 4-burner natural gas grill large enough for a family?
A 4-burner grill is often a practical size for family meals because it gives you separate heat zones for direct and indirect cooking. The Freestyle 425 has 4 main burners, while the Prestige 500 adds infrared side and rear burners.
Choose 5 or 6 main burners when you regularly cook several large items at once.
What care does a natural gas grill need?
Brush cooking grates after cooking, remove grease as directed, and keep burners and openings clear. Stainless steel parts still need regular cleaning, especially when the grill stays outdoors.
Inspect the hose and connection area before use, and follow the manual for lighting, cleaning and storage.
