ElectriChef Diamond 48" Built-In Electric Grill

The required cut-out is 48⅜" wide x 24¼" deep x 10½" tall. The 10½" height is measured from the top of the countertop surface — include the thickness of any tile or granite finish in that measurement. No bottom or sides are required inside the island enclosure. The island itself must be built from non-flammable materials such as masonry, concrete block, or steel stud with cement board.

A NEMA 6-50R receptacle rated for 208/220V, on a dedicated 40-amp single-phase branch circuit. The outlet should be positioned behind the island enclosure so the power cord reaches without an extension. Extension cords must not be used under any circumstances. Consult a licensed electrician before beginning construction.

No. The spec sheet states "No Bottom or Sides Required" inside the island cut-out. The grill's mounting flanges on the sides and back rest on the island countertop surface and support the grill from above. The enclosure does need to be constructed of non-flammable materials.

Yes, the grill is rated for outdoor use. For best results and the longest service life, using a grill cover when the grill is not in use is strongly recommended — particularly in climates with heavy rainfall or humidity. Compatible built-in covers are available separately.

A minimum of 3" of clearance is required at the rear of the grill for the hood to open fully. Plan this into the island depth and any wall or structure behind the counter. With the lid fully open the grill measures 27" above the countertop, so factor that into overhead clearance if the grill is installed beneath a pergola, soffit, or other structure.

Yes. The grill reaches 600°F, which is hot enough to produce proper sear marks and a caramelized crust on steaks, chops, and burgers. You get the sear without any gas or charcoal flavor — the taste is purely the food.

Each of the two control panels operates its own half of the cooking surface independently — temperature setting and a 10–60 minute countdown timer. Run one side at searing temperature and the other at a lower holding temperature simultaneously, without the two zones affecting each other. Both timers trigger automatic shut-off when they reach zero.

When you power on, the grill defaults to 350°F with a 60-minute timer. You can adjust the temperature up or down with the arrow buttons. When the timer counts down to zero, power to the heating elements cuts automatically. If you need more cooking time before it times out, press the ON button to reset the timer to 60 minutes at your current temperature setting.

No. The stainless steel heat-flavor plate beneath the cooking grids distributes heat evenly across the full 48" surface. There are no burner-pattern hot spots or cold zones — consistent heat from edge to edge.

The owner's manual recommends preheating for 10–12 minutes at your desired temperature before placing food on the grill.

All four cooking grids and all four removable grease trays are dishwasher safe. You can also clean grids manually by soaking in hot soapy water to loosen buildup, then rinsing. For the stainless exterior, use warm soapy water and a soft cloth, always wiping in the direction of the brushed grain. Never use abrasive scouring pads, wire brushes, or harsh chemical cleansers on any stainless surface or on the digital control panels.

Yes — provided your space has access to a 208/220V outlet, the island structure is built from non-flammable materials, and your building permits electric grills. ElectriChef grills produce no open flame, which is why they comply with fire codes that ban gas and charcoal in high-rise and multi-unit residential buildings. Always confirm your specific building's rules before purchasing.

No. The owner's manual explicitly prohibits extension cords. The grill must connect directly to a properly grounded 208/220V outlet. If the outlet isn't accessible behind the island, the solution is to have an electrician add a dedicated outlet — not to run an extension cord.

ElectriChef's limited warranty covers the stainless steel grill assemblies for the lifetime of the original purchaser. Cooking grids are warranted for 5 years, the stainless steel heat-flavor plate for 3 years, and all other electrical and mechanical components for a minimum of 1 year from the date of purchase. The warranty covers defects in materials and workmanship; it does not cover damage from misuse or negligence. Labor is not included. Transportation costs for returning defective parts are the buyer's responsibility.

The cooking performance — 1,056 sq. in., 150°F–600°F, dual digital controls — is identical between the two models. The difference is the form factor. The Closed-Base model is a freestanding grill on locking casters with an enclosed storage cabinet, designed to roll into position on a patio or terrace. The Built-In model is a drop-in grill body designed to be permanently installed in a customer-supplied outdoor kitchen island. If you're building a permanent outdoor kitchen, the Built-In is the right choice. If you need mobility or don't have an island, the Closed-Base is the one.

A grill cover is not included. ElectriChef offers compatible built-in grill covers sized for the 48" built-in model, available separately. Using a cover is strongly recommended to protect the stainless finish and controls when the grill is not in use.

The flavor comes from the food and its drippings hitting the heat-flavor plate — not from combustion. You won't get a smoke or gas note, which many cooks find results in a cleaner, truer expression of the ingredient's natural flavor. If you want added smoke, a smoker box with wood chips can be placed on the cooking surface.
