How To Fix Fireplace Insert Draft

How to Fix Fireplace Insert Draft

Fireplace inserts are a popular way to add warmth and ambiance to a home, but they can sometimes develop draft issues. Draft problems can lead to a variety of issues, including inefficient burning, smoke spillage, and a decrease in the overall heating capacity of the fireplace insert. Fortunately, there are a number of things that can be done to fix a draft issue, and most can be done by a homeowner with a little know-how.

Inspect the Damper

The damper is a critical component of a fireplace insert that regulates airflow. If the damper is not properly closed or is damaged, it can allow cold air to enter the fireplace, interfering with the draft.

To inspect the damper, start by opening the fireplace doors. Locate the damper handle, which is typically located near the top of the firebox. Most dampers can be opened and closed using a lever or slide. If the handle is loose or broken, it will need to be repaired or replaced. If the damper is not closing fully or is damaged, it may need to be adjusted or replaced.

Check the Air Intake

Fireplace inserts require a steady flow of fresh air to operate efficiently. This air intake is typically located near the bottom of the insert and is designed to draw in air from outside the home. If the air intake is blocked or restricted, it can lead to a decrease in draft.

To check the air intake, look for any obstructions that may be blocking the airflow. These obstructions can include dust, debris, or even furniture placed too close to the insert. Make sure the air intake is clear and unobstructed. If the air intake is not located in a suitable place, the insert may need to be relocated or the location of the air intake may need to be adjusted.

Inspect the Chimney

The chimney is crucial for proper draft within a fireplace insert. Any blockages, cracks, or damage to the chimney can disrupt the flow of smoke and heat. To inspect the chimney, you can first look up from the firebox opening to see if any obvious blockages exist. If it is accessible, climb up to the top of the chimney to check for any damage or obstructions. If you see any debris or damage, it will need to be cleaned or repaired.

Clean the Fireplace Insert

Accumulation of creosote and soot in the fireplace insert can make it difficult for air to flow properly. This can lead to decreased draft, making the insert difficult to light and inefficient. To clean the fireplace insert, use a stovepipe brush and cleaning tools specifically designed for fireplace inserts. Be sure to remove all soot and creosote from the firebox, chimney, and any other internal parts of the insert. The insert should be cleaned at least once a year, or more often if needed.

Other Considerations

Other factors can also impact the draft of a fireplace insert. These include:

Weather conditions: High winds or a lack of wind can affect the draft.
Barometric pressure: Changes in barometric pressure can also impact draft.
Chimney height: A short chimney can result in a poor draft.

If none of these solutions address the draft problems in your fireplace insert, a professional chimney sweep or fireplace technician can help diagnose and fix the issue.
