FAQ

What is the difference between the Natural Gas and Propane versions?

The Natural Gas version connects to your home's existing natural gas supply line for unlimited fuel without tank refills. The Propane version uses standard 20 lb. propane tanks. Both versions deliver the same performance and features - the only difference is the fuel source. Make sure to select the version that matches your setup before purchasing, as these are not interchangeable without a conversion kit.

Does the Prestige 665 RSIB come with a rotisserie kit?

Yes! The Prestige 665 RSIB includes a heavy-duty rotisserie kit. The grill also features an infrared rear rotisserie burner that is larger than previous models, providing even, powerful heat for whole chickens, roasts, and other rotisserie cooking.

What does SIZZLE ZONE mean, and why does it matter?

SIZZLE ZONE is Napoleon's infrared side burner technology. Unlike a standard gas burner, an infrared burner generates intense, direct radiant heat that can reach extremely high temperatures very quickly. This makes it ideal for searing steaks, chops, and other proteins to lock in juices and create a flavorful crust - similar to what you'd get at a high-end steakhouse.

How does the JETFIRE ignition work?

JETFIRE ignition is Napoleon's battery-free ignition system. When you turn the control knob and press the igniter, it shoots a jet of flame directly at the burner tube, lighting it instantly and reliably. Because it doesn't rely on batteries or an electronic spark, it works in all weather conditions and never needs battery replacements.

How large is this grill, and will it fit on my patio?

The Prestige 665 RSIB measures 74 in. wide, 26 in. deep, and 51 in. tall (with the lid closed). We recommend measuring your available patio or deck space before purchasing and leaving at least 12-18 inches of clearance on each side for safe operation. This is a full-size premium grill designed for serious outdoor cooking setups.

Is assembly required, and how difficult is it?

Yes, some assembly is required. Napoleon provides a detailed Assembly Guide (available for download above) to walk you through the process step by step. Most customers can complete assembly in 1-2 hours with basic hand tools. If you'd prefer professional assembly, we recommend contacting a local grill assembly service.
