Broil King Imperial S 470 Built-In Gas Grill

Yes — the Imperial S 470 is available in both fuel types. Liquid Propane is model 956074-LP; Natural Gas is model 956077-NG. Select your preferred fuel type at the top of this page before adding to cart. If you're not sure which option works with your outdoor kitchen setup, contact us and we'll help you sort it out.

The overall dimensions are 31.06" W × 26.95" D × 24.60" H. These are the full grill head dimensions. For island cutout requirements, refer to the owner's manual or contact us before finalizing your build — cutout specs differ from overall dimensions and are critical to get right before you pour concrete or frame the island.

Per Broil King's specifications, the grill head cutout dimensions are 29.78" wide × 23.13" deep × 10.9" high. The full assembled grill is 31.14" W × 26.37" D × 24.89" H — the cutout is smaller than the overall body, so use the cutout numbers when framing or cutting your island. Refer to the owner's manual for the full installation diagram including countertop overhang and minimum cabinet depth requirements.

The premium rotisserie kit is included with the Imperial S 470. It's not an add-on or separate accessory purchase. Combined with the 15,000 BTU rear rotisserie burner, it's ready to use out of the box.

The four main Dual-Tube burners produce a combined 44,000 BTUs. The rear rotisserie burner adds another 15,000 BTUs, for a total of 59,000 BTUs across the grill.

The primary cooking area is 500 square inches (3,226 sq cm). With the stainless steel warming rack included, total cooking space is 695 sq-in (4,484 sq cm) — a solid amount of real estate for a 32-inch built-in grill.

It uses 4 professional cast stainless steel cooking grids. Cast stainless holds heat better than stamped or cast-iron alternatives and doesn't rust — a meaningful upgrade for a permanent outdoor kitchen installation that will see years of use.

The Flav-R-Wave is Broil King's 304 stainless steel system that sits between the burners and the cooking grids. It's designed to vaporize dripping fats and juices before they can pool and cause flare-ups, circulating that flavor back into the food instead. The result is more consistent, more flavorful results and less babysitting required during a cook.

Yes — the Imperial S 470 includes an insulating sleeve specifically designed for combustible construction material. This is an important detail if your island is framed in wood or another combustible material rather than steel or masonry. Confirm installation requirements with the owner's manual before completing your build.

Yes — the Imperial S 470 includes lights in both the cookbox and the control knobs. The control knobs have blue LED illumination, which makes it easy to read and adjust heat settings after dark.

All three are part of Broil King's Imperial S series with the same premium stainless steel construction and feature set. The main difference is size and cooking capacity: the S 470 is 32 inches with 4 burners and 500 sq-in primary surface; the S 570 steps up to 38 inches; and the S 670 is the largest at 44 inches. If you're building a larger island and want to entertain bigger groups, the S 570 or S 670 may be worth the step up — once the island is in, it's hard to go bigger later.

The S 470 uses Broil King's Sure-Lite electronic ignition system with 180° precision control Linear-Flow valves. Electronic ignition means no external lighter needed — just turn the knob and the burner lights.

Yes — free shipping is included to the contiguous U.S. For full details on transit times and freight delivery, see our shipping policy.

The Imperial S 470 is covered by Broil King's 15-Year Top-to-Bottom warranty, honored directly by Broil King — not through Deck & Den. Standout coverage includes a Lifetime warranty on the stainless steel cookbox, 25 years on lid and cast aluminum components, 15 years on burners, rear burner, grids, and stainless steel components, and 5 years on electronics and lights.
