Napoleon P500RSIBPSS-3 Prestige 500 RSIB Propane Gas Grill, sq. in + Infrared Side and Rear Burner, Stainless Steel

The Napoleon Prestige 500 RSIB is a full-featured stainless steel propane gas grill designed for outdoor cooks who require substantial capacity and diverse cooking methods. Operating on liquid propane, it addresses the needs of regular entertainers who want dedicated zones for high-heat searing, standard barbecuing, and slow rotisserie roasting in a single outdoor unit.

Day-to-day grilling is anchored by four stainless steel main burners that produce 48,000 BTUs per hour across 500 square inches of primary grilling space. This main grate area accommodates up to 31 burgers at once. Underneath the grates, layered stainless steel sear plates distribute heat evenly to prevent cold patches while infusing food with flavor from vaporized drippings. An additional 260 square inches of warming rack space keeps finished batches warm without occupying valuable searing space.

Lighting the grill relies on the JETFIRE ignition system, which directs an individual flame to each main burner during startup. Should an ignition spark falter, Napoleon includes a back channel between burners that allows them to cross-light safely off adjacent active flames. Beyond traditional grilling, the unit provides specialized cooking zones. The infrared Sizzle Zone side burner covers 140 square inches and accelerates to 1800 degrees in 30 seconds for steakhouse-style crusts. Meanwhile, the 18,000 BTU infrared rear burner pairs directly with the included heavy duty rotisserie kit for slow-turning whole meats.

Prospective buyers should note a few hardware considerations. While the standard rotisserie kit is included in the package, specialized attachments like the rotisserie basket for vegetables or wings are sold separately. As a propane-fueled appliance, users must keep filled fuel tanks on hand. The product data also omits exterior cabinet dimensions and total weight, meaning buyers will need to verify deck clearance independently.

Verdict: The Napoleon Prestige 500 RSIB is an outstanding choice for dedicated backyard chefs who regularly feed crowds and want high-heat infrared searing and rotisserie capabilities built directly into their stainless steel setup.

• Main Burner Output: 48,000 BTU-per-hour across 4 stainless steel burners

• Main Cooking Space: 500 square inches (fits up to 31 burgers)
• Secondary Cooking Space: 260 square inches (warming rack) and 140 square inches (side burner)

A great fit if you:

• Host regular backyard gatherings and need enough primary cooking space to prepare up to 31 burgers at the same time.
• Want rapid high-temperature searing from an infrared side burner that reaches 1800 degrees in just 30 seconds.
• Enjoy rotisserie cooking and want a setup that already includes the heavy duty rotisserie hardware and an 18,000 BTU rear burner.
• Appreciate multi-layer reliability from individual flame-throwing burner starters backed by crossover lighting channels.

Consider something else if you:

• Cook solely for one or two people and prefer a compact portable grill that occupies very little deck space.
• Want an all-in-one package that includes specialty accessories like a rotisserie basket without purchasing add-ons separately.
• Do not plan to cook with propane cylinders and need an appliance configured for alternative fuel supplies.

Confirm on the listing:

• Measure your patio or deck footprint and check the listing for overall exterior dimensions, including shelf width and hood clearance.
• Check whether the propane hose and tank connection hardware are bundled with the grill or need separate sourcing.
• Check what assembly steps and tools are necessary before your first cookout.
• Confirm the contents of the heavy duty rotisserie kit to see whether spit forks and mounting brackets match your cooking plans.

How to compare your options: When shopping for a full-sized gas grill, compare total burner output and usable grate area against your typical crowd size. Look closely at secondary cooking elements, as units with dedicated infrared side burners and rear rotisserie burners offer greater recipe versatility than models with standard side rings. Finally, review ignition reliability, since redundant lighting systems ensure you can ignite your burners without handling matches.

• Preheat the infrared Sizzle Zone side burner for 30 seconds to reach searing temperatures before dropping on steaks or chops.
• Stage your cooking by moving finished proteins to the 260 square inch warming rack so you keep primary grates open for high-heat foods.
• Engage the 18,000 BTU rear infrared burner whenever using the included heavy duty rotisserie kit for slow, uniform roasting.
• Wipe down the stainless steel sear plates regularly according to the manual to prevent grease accumulation and promote clean vapor distribution.
• Rely on the primary JETFIRE ignition for standard startups, but use the burner back channels if you ever need to ignite neighboring burners in sequence.
