## 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.

## Questions & answers

**Q: What warranty or support comes with this grill?**

Coverage details are on our warranty page. For any tech help or warranty claim, contact us with your order number and we'll get you taken care of quickly.

**Q: How do I clean this grill, especially the infrared burner, so it keeps cooking well?**

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: For the price, how durable is this grill? Will it handle rough weather?**

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: Can I switch this grill between natural gas and propane later?**

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?**

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.
