A reliable way to address this issue is to use the inverted (or upside-down) lighting method. This method allows heat to build gradually, encouraging the flue to draw air properly and prevent smoke spillage. Below is a step-by-step guide:

​Inverted/Upside-Down Lighting Method

1. Clear the Grate: Ensure there’s no ash or leftover debris on the grate to allow proper airflow.
2. Place Split Logs: Lay two small, split logs across the fire bed, ensuring that some grate holes remain uncovered.
3. Add Kindling: Build a kindling pile with interlaced firelighters on top of the split logs, allowing air to pass through for efficient lighting.
4. Light and Close: Ignite the firelighters and close the stove door. This will gradually increase the fire’s size and heat, warming the flue without excessive smoke.
5. Wait and Adjust: After 5-10 minutes, when the fire is established, adjust the air controls from the lighting position, keeping the secondary air control fully open.
6. Let It Burn: Allow the kindling to light the logs below as it falls. Once they’re burning well, set the air controls to their normal position for ongoing use.
7. Monitor and Re-fuel: Let the logs burn completely before reloading. This helps burn volatile gases that create smoke, preventing smoke leakage when re-fueling.
8. Watch for Charcoal: Wait until you see glowing charcoal on the fire bed before reloading.
9. Prepare to Reload: Set the air controls to fully open before opening the stove door.
10. Open the Door Slowly: Crack the door open slightly to equalize pressure between the stove and room. After 5 seconds, fully open the door and reload the logs.
11. Pro Tip: Keep your new logs nearby so you can minimize the time the door is open.
