How soon can you reduce the air supply in your woodstove after you reload it with wood when the fire is hot and has been going for a while?

After reloading your woodstove with wood, you should wait for a few minutes until the new wood catches fire and the flames stabilize before reducing the air supply. This typically takes about 5 to 10 minutes. Once the fire is established and producing consistent heat, you can then gradually adjust the air supply to optimize combustion and efficiency. It's important to monitor the fire to ensure it continues to burn well without smoldering.
