A wood stove that extinguishes when the door is closed can be frustrating and concerning. In this article, we’ll explore the technical details behind this issue and provide practical solutions for both technical and non-technical users.
Understanding the Problem
When a wood stove fire consistently goes out upon closing the door, it usually indicates a problem with the combustion process. The primary cause is a lack of oxygen, necessary for the fire to burn. Here are the common reasons:
1. Insufficient Draft
Technical Explanation: Draft refers to the flow of air through the stove, carrying away combustion gases. If there’s not enough draft, the stove may not get enough oxygen.
Solution: Ensure your chimney is clear of obstructions, and the damper is open. Check for a proper height and construction of the chimney. You might need professional inspection and cleaning.
2. Air Control
Technical Explanation: Most wood stoves have air controls that regulate the flow of oxygen into the firebox. Closing them too much can reduce the oxygen supply.
Solution: Adjust the air controls to allow for better airflow while the door is closed. Refer to your stove’s manual for guidance.
3. Wet or Green Wood
Technical Explanation: Wet or green wood has a high moisture content, making it harder to ignite and sustain a fire.
Solution: Only use properly seasoned firewood with a moisture content of around 20% or less. Seasoned wood burns more efficiently and generates less creosote.
4. Gasket or Seal Issues
Technical Explanation: The door gasket or seal around the stove may be damaged or improperly installed, allowing excess air to enter and disrupt combustion.
Solution: Inspect the door gasket for any damage or gaps. Replace it if necessary. Ensure it forms a tight seal when the door is closed.
5. Blocked Air Intake
Technical Explanation: Some stoves have an air intake for combustion air. If this intake is obstructed, it can reduce the airflow.
Solution: Check and clear the air intake to ensure it’s free from debris or obstructions.
Safety Precautions
Do not leave the stove unattended: If you are experiencing issues with your wood stove going out when the door is closed, it’s essential to monitor it closely to prevent unsafe conditions.
Use Carbon Monoxide Detector: Install a carbon monoxide detector in the same room as your wood stove to ensure you’re alerted to any potential issues.
Conclusion
A wood stove that extinguishes when the door is closed is typically a solvable issue. It often stems from a lack of oxygen, draft problems, air control mismanagement, or the use of improper wood. Regular maintenance, proper wood selection, and a well-functioning chimney are keys to resolving this problem and enjoying a warm, efficient wood stove. If you’re unsure about any technical aspects, consider consulting a professional for assistance.
