Specifications side by side

How to choose the right built-in griddle

1. Check your fuel source first

   Your existing utility connections dictate which unit you can install. The Blaze Premium LTE model requires a dedicated natural gas line, making it ideal for permanent outdoor kitchens with existing infrastructure. If you rely on propane tanks, the Napoleon 700 Series offers a compatible propane connection. The Livory burner provides flexibility by supporting both propane and natural gas inputs. Verify your fuel availability before selecting a model to avoid costly retrofitting or installation delays. Match the unit to your current setup for a seamless integration process.

2. Measure your available space carefully

   Built-in units require precise measurements to fit your outdoor island or grill. The Blaze griddle has a width of 30 inches and weighs 121 pounds, demanding a sturdy, level surface. The Napoleon insert is narrower at 28.2 inches but adds significant length to your cooking zone. The Livory burner is more compact at 25.8 inches wide, fitting smaller side burner slots. Always measure the cutout dimensions and ensure your structure can support the weight. Proper spacing ensures safe operation and a clean, professional appearance in your outdoor kitchen design.

3. Verify grill compatibility requirements

   Some griddles are designed to work only with specific grill models. The Napoleon Stainless Steel Griddle Insert is engineered to expand compatible Prestige or Rogue grills. It does not function as a standalone unit but rather as an accessory. The Napoleon 700 Series is built for users with BIG32 grill setups. If you do not own these specific compatible appliances, these inserts will not work for your setup. Check your existing grill model number against the manufacturer’s compatibility list before purchasing to ensure the unit will physically and functionally integrate with your current equipment.

4. Consider the cooking surface material

   Durability and maintenance depend heavily on the construction material. All listed units feature stainless steel surfaces, which resist rust and withstand high outdoor temperatures. The Napoleon 700 Series specifies a 5mm thick cooking surface, which retains heat better and resists warping over time. Thicker steel generally provides more consistent cooking results for searing meats or frying eggs. Stainless steel is also easier to clean and maintain compared to cast iron, which requires seasoning. Choose a unit with robust material specifications to ensure longevity and consistent performance in various weather conditions.

5. Define your primary cooking goal

   Your intended use case determines the best form factor. If you want to add flat-top capabilities to an existing grill, the Napoleon insert is the practical choice. For supplemental side cooking or extra burners, the Livory double side burner provides high heat in a compact footprint. The Blaze and Napoleon full-size griddles are better suited for primary cooking surfaces for large meals. Consider whether you need a dedicated griddle zone or a flexible burner for side dishes. Align the product’s primary function with your cooking habits to avoid buying a unit that sits unused.
