Buying Guide
BTU Output and Burner Configuration
The total BTU rating tells you the maximum heat potential, but how that heat is distributed matters more. For a 32 inch grill, you want burners that provide even heat across the entire cooking surface. Both models here deliver substantial power, but their burner designs differ. The Napoleon Built-In 700 Series uses four stainless steel main burners plus an infrared rear rotisserie burner, giving you versatile cooking zones. The Bull Outdoor Products Outlaw features four welded stainless steel burners, each producing 15,000 BTUs for consistent heat. Look for a grill that balances high BTU output with burner quality to avoid hot spots.
We recommend considering how you typically cook. If you often grill for large groups or enjoy rotisserie cooking, the Napoleon’s additional infrared burner is a major advantage. For straightforward grilling with reliable performance, the Bull Outlaw’s uniform burner system is hard to beat. For more on grill features, browse our Best Products page.
Build Quality and Materials
A built in grill is a permanent fixture, so durability is non negotiable. Stainless steel construction, especially 304 grade, resists rust and withstands outdoor elements. The Napoleon grill uses thick stainless steel cooking grids that are nearly maintenance free, while the Bull Outlaw is crafted from 304 stainless steel with a dual lined hood for excellent heat retention. Both models feature solid cooking grates that deliver great sear marks. Pay attention to the gauge of steel and the quality of welds; these details determine how long your grill will last.
Another factor is the ignition system. The Napoleon uses a failsafe battery free ignition that lights burners instantly with a jet of flame, adding reliability. The Bull Outlaw uses a Piezo ignition system, which is also dependable. We have seen similar durable builds in other top rated grills, such as those featured in our Best Flat Top Grill for Your Money guide.
Cooking Area and Versatility
The cooking area determines how much food you can prepare at once. The Napoleon offers a generous 29.5 inch by 18 inch primary cooking space, plus an integrated rotisserie kit for spit roasting. Its wave shaped grids prevent food from falling through and create exceptional sear marks. The Bull Outlaw provides 575 square inches of primary cooking space plus a 176 square inch warming rack, giving you room for multiple dishes. Consider whether you need a warming rack for keeping sides hot while finishing mains.
Both grills also include interior lighting for nighttime grilling, which is a practical feature for evening cooks. The Napoleon even has backlit control knobs that glow blue then red when burners are on, adding ambiance. If you enjoy outdoor cooking after dark, these illuminated features enhance safety and convenience.
Ease of Installation and Maintenance
Built in grills require precise cutouts and gas line connections, so installation ease is crucial. The Napoleon is designed with integrated trim, longer electrical wiring, and an extra long flex line, allowing a 2 inch tolerance for cutouts. This flexibility reduces design restrictions. The Bull Outlaw is a drop in model, which also simplifies installation. Both come with grease management systems to minimize buildup and reduce fire risk. The Napoleon’s dual level sear plates direct drippings to perforated plates, while the Bull Outlaw’s design ensures easy cleaning.

Frequently Asked Questions
What size cutout do I need for a 32 inch built in gas grill? Most 32 inch grills require a cutout width of approximately 30 inches to 31 inches, with a depth of around 18 to 20 inches. Always check the manufacturer’s specifications for your specific model, as tolerances vary. The Napoleon provides a 2 inch tolerance for easier installation.
Can I use a natural gas grill with a propane tank? No, natural gas grills are designed for a permanent natural gas line and cannot be converted to propane. If you do not have a natural gas hookup, look for a propane model or consider a conversion kit only if the manufacturer supports it.
How do I maintain a stainless steel built in grill? Clean the cooking grids and sear plates after each use with a grill brush. Wipe down the exterior with a mild stainless steel cleaner to prevent rust. Cover the grill when not in use, even if built in, to protect against weather. Both reviewed models have grease management systems that simplify cleanup.
What is the advantage of an infrared rotisserie burner? An infrared rotisserie burner provides intense, even heat for spit roasting meats like whole chickens or roasts. It cooks from the rear, allowing the food to rotate slowly and self baste, resulting in juicy, flavorful results. The Napoleon includes this feature, making it ideal for rotisserie enthusiasts.
