Buying Guide
Key considerations when selecting cast iron wood-burning inserts and grates:

- Fit and installation: Measure hearth width, depth, and clearance to combustibles; ensure chimney compatibility and proper venting.
- Airflow and combustion: Grates with raised log supports improve airflow; ember retainers help contain debris and simplify cleaning.
