Is There a Risk of Carbon Monoxide with Wood Cookstoves?

April 5, 2026

Quick Answer

Yes, there is a risk of carbon monoxide with wood cookstoves if they are not properly installed, maintained, and used. Improper ventilation and creosote buildup are common causes of carbon monoxide poisoning. Regular maintenance and proper installation can significantly reduce this risk.

Proper Ventilation and Installation

Proper ventilation is crucial to preventing carbon monoxide buildup with wood cookstoves. Ensure that your stove is installed with a direct vent or B-vent system, which draws combustion gases outside. A well-maintained chimney is also essential, as creosote buildup can lead to carbon monoxide poisoning. Consider installing a CO detector near the stove to alert you of potential danger.

Maintenance and Regular Checks

Regular maintenance of your wood cookstove is vital to preventing carbon monoxide buildup. Check your stove’s chimney and flue annually for signs of creosote buildup. Clean or replace the chimney as needed to prevent blockages. Also, inspect your stove’s damper, ensuring it is functioning correctly. A clogged or faulty damper can increase the risk of carbon monoxide poisoning.

Safety Precautions and Best Practices

To minimize the risk of carbon monoxide poisoning when using a wood cookstove, follow these best practices: never leave a wood cookstove unattended while burning, ensure proper ventilation, and maintain your stove regularly. Avoid burning pressure-treated wood, as it releases toxins that can combine with carbon monoxide. Never store fuel or combustible materials near your stove, and keep the area around your stove clear of clutter to ensure good airflow.
