Are You Using Your Damper Correctly?
Have you ever experienced a smoky fire with that lingering smell? For most, it’s an undesirable smell. And it could be related to how homeowners use their dampers. It’s a small, but critical component. Proper damper use can improve safety, efficiency, and comfort. It’s a part of the chimney that may get overlooked, so it’s important to know how it works.
What Is A Chimney Damper?
A chimney damper is a movable metal plate or valve that controls airflow in your chimney. Its primary purpose is to control smoke and airflow. It opens to allow smoke and combustion gases to safely exit and closes when not in use to prevent heat loss and drafts. It’s typically located just above the firebox, inside the throat of the fireplace.
To operate the damper, first find a lever, knob, or chain inside the firebox to control it. In the open position, the plate is vertical, allowing airflow. In the closed position, the plate is horizontal, and airflow is blocked. There are also top-sealing dampers at the tops of some chimneys, operated by a cable or chain.
Why Proper Damper Use Matters
Proper damper use goes beyond comfort. To ensure safe burn conditions, smoke and carbon monoxide must vent properly. It also impacts efficiency as a closed damper impacts heating and cooling costs. These are both in addition to preventing drafts, odors, and cold air infiltration. Improper damper use can lead to smoke backup, creosote buildup, and energy loss.
How to Use Your Damper the Right Way
Before starting the fire, it is imperative to double-check that the damper is fully open. This will allow the air to flow as it should and fire to light.
During the fire, never play with the damper. Once a fire is lit, the damper must remain fully open at all times.
After the fire, wait until the ashes and embers are completely cool. Even after the flames are gone, the embers can continue to produce smoke and carbon monoxide. You don’t want to trap gases and force them back into your home. Once it is fully cooled down, make sure to close the damper to prevent heat loss.
Signs Your Damper May Need Repair or Replacement
There are a few telltale signs of damage related to your damper. Look out for the following:
- Difficulty opening or closing the damper
- Rust, warping, or visible damage on or around the damper
- Persistent drafts or lingering odors in your home
- Smoke entering the room
- Visible gaps near your damper when closed
