Draft from Fireplace Insert: Causes and Solutions

A cozy fireplace insert is a welcome addition to any home, but it can quickly become a source of frustration if you experience a persistent draft. A draft can be a sign of a problem with your insert, the installation, or even your chimney. This article will help you understand the common causes of draft from fireplace inserts and guide you towards effective solutions.

Common Causes of Draft in a Fireplace Insert

1. Poor Seal: A draft from a fireplace insert often arises from a poor seal between the insert and the fireplace opening. This can occur due to:

   • Improper installation: The insert may not be properly fitted or secured, leaving gaps that allow cold air to enter.
   • Damaged or worn-out gaskets: The gaskets that create a seal around the insert can become damaged or lose their elasticity over time, compromising the airtightness.
   • Uneven fireplace opening: If the fireplace opening is not perfectly level or has gaps, it can cause a mismatch between the insert and the opening, leading to drafts.

2. Chimney Issues: A draft in your fireplace insert could be a symptom of a problem with your chimney. These include:

   • Cracked or damaged chimney: Cracks or holes in the chimney can allow cold air to enter, creating a draft.
   • Blocked chimney: A blockage, such as bird nests or debris, can hinder proper airflow and cause a draft.
   • Insufficient chimney height: A chimney that is too short or does not meet the recommended height requirements can cause a negative pressure, drawing in cold air.

3. Air Intake Problems: The insert's air intake can also be a source of drafts if:

   • Air intake is blocked: If the air intake is blocked, it can create a negative pressure inside the insert, drawing in cold air from other areas.
   • Insufficient air intake: The air intake might not be large enough for the insert's needs, resulting in a draft.

How to Fix Draft from Fireplace Insert

1. Inspect and Seal the Insert:

   • Examine the gaskets: Check for any signs of damage, wear, or loose connections. Replace any damaged gaskets with new ones specifically designed for fireplace inserts.
   • Inspect the seal: Carefully inspect the entire perimeter of the insert for gaps or areas where the seal might be compromised. Use high-temperature sealant or fire-resistant caulk to fill any gaps.
   • Check the installation: Ensure that the insert is firmly secured and properly installed. If necessary, consult a professional for guidance on re-installation.

2. Address Chimney Issues:

   • Chimney inspection: Schedule a thorough chimney inspection by a certified chimney sweep to identify any cracks, blockages, or other issues.
   • Chimney repairs: If the inspection reveals any problems, address them promptly with appropriate repairs or replacements.
   • Chimney height: If your chimney is too short, consider extending it to meet the recommended height for your insert.

3. Adjust the Air Intake:

   • Clear any blockages: Remove any obstructions from the air intake to ensure proper airflow.
   • Consider increasing the intake: If your intake is too small, discuss the possibility of increasing its size with a qualified professional.

4. Other Solutions:

   • Install a draft stopper: This simple device can be placed at the bottom of the fireplace opening to prevent cold air from entering.
   • Use a fireplace screen: A fireplace screen can help to deflect drafts away from the living area.
   • Invest in a high-quality insert: Some inserts are designed with improved sealing technology and more efficient air intake systems that minimize drafts.

Professional Help

If you're unable to resolve the draft issue yourself, it's recommended to consult a fireplace professional. They can provide a comprehensive inspection, identify the root cause of the problem, and recommend the most effective solutions.

Remember, a draft from a fireplace insert can be a sign of a serious problem that needs to be addressed. By taking the necessary steps to identify and fix the issue, you can ensure a comfortable and enjoyable experience with your fireplace.
