Blue Sky 28 Inch Phoenix Round Wood Burning Smokeless Fire Pit Insert

The Blue Sky 28 Inch Phoenix Round Wood Burning Smokeless Fire Pit Insert has an overall diameter of 33 1/2 inches and an insert diameter of 26 inches. It is designed for use within a 29 to 32-inch built-in fire pit structure. Your drawing indicates an inside diameter of approximately 28 to 29 inches and suggests a steel fire ring insert of 30 or 32 inches. While the 26-inch insert diameter of our product would physically fit within your 28 to 29-inch opening, the recommended minimum opening for this fire pit insert is 29 inches, and your drawing explicitly suggests a larger 30-inch or 32-inch insert. Therefore, it may not be the ideal fit based on the drawing's recommendations for insert size.
