How Do You Know When to Repair Your Chimney Damper?
A chimney damper is responsible for controlling the flow of smoke through the chimney as well as ventilation. If a chimney damper breaks, it can prevent homeowners from using their fireplaces effectively.
We will share a few tips about how to determine if you need to repair your chimney damper.
Chimney damper explained
Chimney dampers are also known as throat dampers. It’s a seal or lid inside the chimney flue that operates by a pull or chain system located towards the top of the firebox. The chimney damper covers the flue and prevents the cold air from drifting down into the chimney and making its way into the home. We open the damper so the smoke can make its way through the chimney when using the fireplace.
Chimney damper issues
When not properly maintained, a chimney damper can suffer several problems. The most common include:
An off-track flue damper plate
If a flue damper plate is off track, it affects the direction of the smoke through the chimney.
Air drafts
When cold air starts to travel down the chimney, it enters the home and disrupts the heating system in place.
Faulty operation
If the damper doesn’t allow enough smoke to get out, it means it doesn’t run as it should.
Damper not closing
Dampers that don’t close worsen draft problems and let air escape from the home.
Damper not opening
If the damper doesn’t open, the whole fireplace can become inoperable. This issue requires immediate attention.
Broken dampers
If the damper plate is broken, cracked, or has fallen off, you will need to replace it.
The problems listed above are signs that the chimney damper needs to be inspected or repaired. Even if not used often, it’s essential to have regular chimney inspections to ensure everything is functioning safely and efficiently.
Repairing the chimney damper
Homeowners can repair chimney dampers by following the steps below:
Removing debris
Before removing the damper, make sure to clean the debris and creosote. They may block the hinges and prevent the damper from opening or closing. First stage creosote buildups are easy to remove, while later-stage buildups often require new damper installation.
Removing damper plate
If you look upward from the firebox, there will be a rod affixed to the chimney by a nut. Proceed by loosening the nut and removing the rod until the damper plate comes off. If it doesn’t, twist until you can remove it.
Cleaning parts
Clean all parts, including the resting frame of the damper, the plate, and the rod. Also, make sure to look for signs of corrosion.
Change the plate
After cleaning everything, change the damper plate if there are no other issues. The nut and rod should go on tight until aligned.
