Description

The Sunstone 28" 3-Burner Built-In Gas Grill with Infrared Burner (SUN3BIR) is a heavy-duty grill for an outdoor kitchen island, with a rear infrared burner for rotisserie cooking. It runs on natural gas or propane.

Three main burners at up to 20,000 BTU each give up to 60,000 BTU, and the infrared rear burner adds up to 15,000 BTU, for up to 75,000 BTU total. That lets you sear on one zone and slow-cook ribs on another. The cooking surface is 484 sq. in. on heavy-duty 3/8" stainless steel grates. A complete rotisserie kit (rod, forks and motor) is included.

Electronic ignition starts it quickly, and the double-wall hood has a built-in temperature gauge. The grill is 304 stainless steel with edges that have no seams, which helps it resist corrosion. It is 28" wide.

Solid grill, some learning curve

This 28 inch grill is a beast. Feels really durable and it fit perfectly in my custom island. The main burners heat up fast, but the infrared burner took a little getting used to for searing steaks right.

Diego L.★★★★☆September 3, 2020
Great addition to our patio

We've wanted a built in grill forever and this one delivered. Three burners is plenty of cooking space for our family and it looks really sleek. My contractor said the install was straightforward.

Warren M.★★★★☆May 15, 2015
Cooks great, pricey

Cooks really well, no complaints there. You can tell the heat is even, and the infrared burner does great with chicken. My only real gripe is the price, it's definitely more than other options out there.

Todd C.★★★★★January 4, 2009
Love this grill

Love this grill. Really well built and looks great in our outdoor kitchen. The infrared burner gets a perfect crust on burgers and steaks. Recommend it if you grill a lot.

Alejandro W.★★★★★June 10, 2024
Worth the money

This 28 inch grill beat my expectations. I could tell it was quality as soon as it was in. Heat control is precise and I've cooked everything from fish to thick steaks perfectly. You won't regret it.

Questions & answers

5 questions answered

Q
For the price, how durable is this grill? Will it handle rough weather?Asked by Sunstone Support Team
A
Yes. It's 304-grade stainless steel, which is very durable and resists corrosion. It's great outdoors and handles strong sun, rain and humidity, so it'll look good and cook reliably for years. Cleaning it regularly helps it last even longer.

Q
How do I clean this grill, especially the infrared burner, so it keeps cooking well?Asked by Sunstone Support Team
A
For routine cleaning, use a stainless steel cleaner on the outside and a grill brush on the grates after each use. For the infrared burner, run it on high for a few minutes after cooking to burn off residue, then brush it gently. Don't use harsh abrasives on the stainless, and make sure the grill is cool before you do a deep clean.

Q
Can I switch this grill between natural gas and propane later?Asked by Sunstone Support Team
A
It usually comes set up for either natural gas or propane when you buy it. Converting it isn't recommended unless a qualified tech does it with an official Sunstone conversion kit, since a bad conversion can void your warranty and isn't safe. It's best to pick your fuel type up front.

Q
I'm planning a new outdoor kitchen. How hard is this grill to install and what do I need ready?Asked by Sunstone Support Team
A
It's made for a simple built-in install. Measure your island cutout carefully, it usually needs a 28.5" W x 20.5" D x 10.25" H opening. We recommend a certified gas pro connect the gas line so it's safe and works right, whether you're on natural gas or propane.
