Firebox for Kamado Pro 22" TUNABONE — charcoal firebox insert for 22-inch kamado grills

The Firebox for Kamado Pro 22" by TUNABONE is a charcoal insert engineered to fit 22-inch kamado-style grills. Designed as the dedicated charcoal chamber and heat source, this firebox provides a controlled combustion area that simplifies fuel loading and ash handling. It supports common kamado cooking methods including grilling, smoking and searing while improving airflow control and routine maintenance for everyday outdoor cooking.

Advantages

The firebox creates a stable burn zone that enhances temperature consistency and reduces the need for frequent refueling. Its insert design keeps charcoal contained for easier ash removal and lowers the risk of embers spilling into the main ceramic body. By improving airflow management, it enables more precise temperature adjustments and better fuel efficiency during long cooks. The construction is intended to be durable under high heat and to integrate with existing 22-inch kamado grill configurations.

Suitable for

• Direct grilling and high-temperature searing of steaks, burgers and vegetables
• Low-and-slow smoking of ribs, brisket and poultry
• Everyday outdoor cooking and weekend barbecue sessions
• Users who need simpler charcoal loading and ash cleanup

How to use

Place the firebox insert into the kamado’s base following the grill manufacturer’s instructions for 22-inch models. Add a bed of charcoal inside the insert, arrange larger lumps for initial ignition and smaller pieces for steady burning, then light according to standard charcoal-start procedures. Adjust the kamado vents and any integrated dampers to regulate airflow and reach the desired cooking temperature. Monitor temperature with the grill’s thermometer or a probe and add fuel through the firebox as needed for extended cooks. To remove ash, let the unit cool completely, then lift out the insert and empty ash into a non-combustible container.

Usage recommendations

Use quality lump charcoal for more consistent heat and reduced ash production. Allow the firebox to cool fully before handling and perform regular inspections for heat-related wear. Follow the kamado grill manufacturer’s safety guidelines when installing and operating the insert to maintain proper clearance and prevent damage to the ceramic shell.
