## Description

The Sunstone 28" 3-Burner Built-In Gas Grill (SUN3B) is a heavy-duty grill for an outdoor kitchen island, sized for everyday barbecues and entertaining. It runs on natural gas or propane.

Three 304 stainless steel burners at up to 20,000 BTU each give up to 60,000 BTU total, so you can sear over high heat on one side and cook ribs slower on another. The cooking surface is 484 sq. in. on heavy-duty 3/8" stainless steel grates. 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.

## Questions & answers

**Q: What's the warranty on this grill? If a burner or igniter acts up, how do I get help?**

Coverage details are on our warranty page. If you have an issue with a burner, the igniter or anything else, contact us with your order number and we'll help with parts or troubleshooting.

**Q: How hard is this grill to clean after a big cookout? Any products or tips to keep it looking good?**

It's pretty easy since it's stainless. Brush the grates with a good grill brush after each use while they're still warm. For the outside, mild dish soap and water with a soft cloth keeps the stainless shiny. Always wipe with the grain, and don't use abrasive cleaners or steel wool, they'll scratch it.

**Q: For the price I want this grill to last. What's it made of and how does it hold up?**

It's mostly commercial-grade 304 stainless steel, which is very durable and resists rust and corrosion even in tough outdoor conditions. That includes the burners and cooking grates, so with some care it'll keep performing for years. It makes a reliable centerpiece for an outdoor kitchen.

**Q: What gas hookup does this grill use? Can I switch between natural gas and propane later?**

It comes in both natural gas and propane versions, and you pick the one you need when you order. Conversion kits exist for some other grills, but it's best to buy the right fuel type from the start, since converting a built-in grill can be complicated and may void your warranty if a certified pro doesn't do it.

**Q: I'm upgrading my old grill. Will this 28 inch drop into my existing cutout, or will I need custom work?**

It's made for a simple built-in install. It usually fits a cutout around 27-1/4" W x 10-1/4" H x 21-1/2" D, which is pretty standard for 28 inch grills. Check your current cutout against the exact specs to make sure it fits, but it usually works well as a replacement.
