If I run into an issue with a burner or igniter, how do I get support?** For specific details and support, you should always refer to the warranty card included with your product or contact Sunstone's customer service directly via their website. They are usually very responsive in assisting with parts or troubleshooting. See our warranty page for coverage details. **Q: How difficult is it to clean the Sunstone® 28-Inch 3-Burner Built-In Gas Grill after a big cookout? Are there any special cleaning products or techniques I should use to keep it looking good?** Cleaning the Sunstone® 28-Inch 3-Burner Built-In Gas Grill is relatively easy thanks to its stainless steel construction. For the cooking grates, a good quality grill brush after each use while still warm is ideal. For the exterior, a mild dish soap and water solution with a soft cloth will keep the stainless steel gleaming, always wiping with the grain. Avoid abrasive cleaners or steel wool, which can scratch the finish. **Q: Considering the $2423.00 price tag, I want to make sure this grill will last. What are the main materials used, and how well do they hold up to outdoor elements and frequent use?** The Sunstone® 28-Inch 3-Burner Built-In Gas Grill (SUN3B) is constructed primarily from commercial-grade 304 stainless steel, which is renowned for its exceptional durability and resistance to rust and corrosion, even in harsh outdoor environments. This high-quality material extends to the burners and cooking grates, ensuring longevity and consistent performance for many years with proper care. It's built to be a reliable centerpiece for your outdoor kitchen. **Q: What kind of gas hookup does this grill use? Can I convert it from natural gas to propane or vice-versa if my setup changes down the road?** The Sunstone® 28-Inch 3-Burner Built-In Gas Grill (SUN3B) is available in both natural gas (NG) and liquid propane (LP) configurations. When ordering, you'll select the specific fuel type you need. While conversion kits are sometimes available for other grills, it's best to purchase the correct fuel type upfront as converting built-in units can be complex and may void your warranty if not done by a certified professional. **Q: I'm looking to upgrade my old grill. Is the Sunstone® 28-Inch 3-Burner Built-In Gas Grill easy to install into an existing cutout, or will I need to do a lot of custom work?** The Sunstone® 28-Inch 3-Burner Built-In Gas Grill (SUN3B) is designed for straightforward built-in installation. It typically fits a cutout around 27-1/4" W x 10-1/4" H x 21-1/2" D, which is a fairly standard size for 28-inch grills. We recommend checking your current cutout dimensions against the product's exact specifications to ensure a perfect fit, but generally, it's quite accommodating for replacements.
