Smoke not escaping from stove

How to Prevent Smoke Escaping from Your Log Burner Door

One common frustration that many Stove users encounter is the escape of smoke when adding more wood. This issue is not only unpleasant, but it can also be a sign of inefficient burning. 
Fear not, though, as we've compiled a list of tips and tricks to help you prevent smoke from infiltrating your room and keep the warmth inside the log burner.

Build a Solid Foundation:

The way you arrange your logs can significantly impact the combustion process. Start by placing larger logs at the bottom, creating a stable foundation. Stack smaller logs and kindling on top, leaving enough space for air circulation. A well-constructed fire promotes proper airflow, reducing the likelihood of smoke escaping when you open the door.

Use Properly Seasoned Wood:

Moisture content in wood is a critical factor in efficient burning. Wet or unseasoned wood not only produces more smoke but can also lead to creosote buildup in your chimney. Ensure your wood has been properly seasoned for at least six months, allowing it to reach an optimal moisture content of around 15-20%.

Prime the Flue:

Before opening the log burner door to add more wood, prime the flue by fully opening the air vents for a few minutes. This helps establish a strong upward draft, directing smoke up the chimney rather than into your living space.

Slightly open the door before fully opening it:

The airflow dynamics within the stove may shift when you first slightly open the door. To address this, make sure to gently crack the door and pause for approximately 10-20 seconds before fully opening it. This brief interval allows for the establishment of a new airflow pattern. Following this, you can proceed to gradually open the door.

Time Your Wood Additions:

Choose the right moment to add more wood. Wait until the flames are strong and the existing logs have formed a bed of embers. Opening the door at this point allows for a quick and efficient reignition of the new wood, minimizing smoke production.

Close the Damper Properly:

After adding more wood, make sure to securely close the log burner door and the damper. This prevents excess air from entering the stove and interfering with the combustion process. A closed damper helps maintain control over the fire and reduces the chances of smoke escaping.

Check for Leaks:

Over time, rope gaskets and seals on log burner doors can wear out, leading to air leaks. Inspect these components regularly and replace any damaged parts to ensure a tight seal when the door is closed.

Invest in Quality Firewood:

The type of wood you use matters. Properly seasoned wood produces less smoke Investing in higher quality firewood can make a noticeable difference in both heat output and smoke reduction.


By implementing these tips, you can enjoy a smoke-free experience with your log burner, enhancing both the comfort and efficiency of your home heating. Remember, a well-maintained and properly operated log burner not only provides warmth but also adds a charming and rustic atmosphere to your living space. With a little care and attention, you can keep the smoke where it belongs – up the chimney – and revel in the warmth of a perfect fire.
