Napoleon – Prestige 665 Gas Grills

Napoleon Prestige® 665 Gas Grill

When the Prestige 500 isn’t enough grill—more guests, more food, more cooking methods running at the same time — the Prestige 665 is the answer. Available in a standard model and a Connected model, both offered in propane or natural gas, this is a full-size, full-featured grill built for people who cook seriously and entertain often.

Scale That Actually Matters

The Prestige 665 gives you 1,254 square inches of total cooking area across the main grate and warming rack — enough to cook up to 41 burgers at the same time. Seven burners give you the control to match: 5 main stainless steel tube burners producing 94,000 BTUs total, plus a dedicated infrared SIZZLE ZONE™ side burner and an infrared rear rotisserie burner.

That means you can be direct grilling on one zone, running indirect heat on another, searing on the side burner, and holding finished food on the warming rack — all at once, without crowding anything.

Infrared Searing and Rotisserie

The SIZZLE ZONE™ side burner reaches the kind of high temperatures that produce a real sear — the crust you’d expect from a steakhouse, not a standard backyard grill. Use it for steaks, thick chops, or anything that benefits from fast, intense direct heat while the main grates handle the rest of the spread.

The rear infrared rotisserie burner powers the included heavy-duty rotisserie kit for slow, even roasting. Whole chickens, pork loin, leg of lamb — anything that benefits from rotating heat comes out better on a dedicated infrared rear burner than a standard one.

Standard or Connected — Your Call

Both models share the same cooking platform, the same burners, and the same BTU output. The difference is what the Connected model adds on top.

The Prestige 665 Connected pairs with the Napoleon app over Wi-Fi or Bluetooth to give you real visibility into your cook from your phone. Three included temperature probes let you monitor doneness across multiple cuts simultaneously without lifting the lid. A 5″ LCD display on the grill keeps everything readable at a glance. Cook assist, timer control, high-temperature warnings, and remote monitoring round out the connected features. For propane users, the digital tank scale gives you an accurate read on remaining fuel so you’re never caught short mid-cook.

If you grill regularly and want that level of control, the Connected is worth it. If you’d rather keep things straightforward, the standard 665 delivers the same core performance without it.

Built to Last

Both models are constructed in Canada from rust-resistant stainless steel throughout—exterior, basin, tube burners, sear plates, and cooking grids. The WAVE™ cooking grids are 7.5 mm-thick 304 stainless steel, shaped to maximize food contact, prevent smaller items from falling through, and produce Napoleon’s signature sear marks. Dual-level sear plates beneath the grids vaporize drippings before they can cause flare-ups, keeping your food moist and your cooking surface clean.

Michigan weather is hard on outdoor equipment. The Prestige 665 is built for it — the same materials and construction that make it a great grill in July make it one that’s still performing years down the road.

Designed for Real Cooks

JETFIRE™ battery-free ignition lights every burner reliably without the frustration of dead batteries or failed clicks. SafetyGlow™ LED control knobs glow red when a burner is running — clear and visible whether you’re mid-cook or wrapping up at the end of the night. A stow-away warming rack tucks out of the way when you need room and back into position when you need to hold food at a temperature. Hidden tool hooks keep side shelf space clear, and industrial locking casters give you stability when the grill is set and easy movement when it’s not.

Propane or Natural Gas

Both the standard and Connected models are available in propane and natural gas. If you’re running a tank, propane is straightforward. If you’re building a permanent outdoor kitchen with a direct gas line, the natural gas models are the cleaner solution. Our team at Fireplace Gallery can help you figure out which configuration makes sense for your setup.
