Installation & Care Tips
- Clean Out the Base First: Completely clear all old lump charcoal, fine ash, and debris from the bottom ceramic base before positioning the new firebox.
- Check Alignment & Clearance: Lower the new firebox straight down using both hands. Ensure it sits level on the ceramic bottom plate/shoe and aligns properly with the lower stainless steel draft door opening.
- Replace Charcoal Grate: Make sure the proper side is facing up when setting the grate inside the firebox.
- Prevent Thermal Stress: Always place ceramic spacers or deflector feet properly inside the grill during high-heat cooks. Avoid pouring cold liquids into a hot firebox.
