Types of Chimney Damper

There are generally two types of chimney dampers available in the market. They are classified based on where they are placed. They are chimney throat dampers and top-sealing dampers.

The chimney throat dampers are placed over the fireplace. It is placed so close to the fireplace. That’s why the efficiency decreases over time because of the fireplace’s heat.

On the other hand, the top sealing chimney damper is placed on the upper part of the chimney but not inside the chimney. This damper generally includes a gasket system. 

It can seal the damper tightly so that any energy or heat can’t be lost. Also, the seal can keep anything out of the fireplace. You should choose your chimney damper according to the chimney or fireplace.


How to Install a Chimney Damper

The installation process of the chimney damper can vary according to the damper type you use. The steps to install the chimney damper are explained below.

  • First, you need some equipment to set the chimney damper. The types of equipment are a wire cable, wrench, mounting bracket, silicon cement tube, anchor nails, hammer, wire cutter, and drill machine.
  • You have to spread silicon on the top part of the flue. You can find the silicon from the silicon tube.  
  • You have to carefully set the wire cable into the chimney, so it doesn’t get tangled.
  • Then you can place the chimney damper on the silicon-filled flue.
  • You have to place the mounting bracket perfectly from the 20 inches of the surface wall. You have to drill two holes through the frame.
  • Then you can place the two anchor nails through the mounting bracket holes with the help of a hammer.
  • You have to connect the chain cable with the mounting bracket. 
  • You have to lose the clamp with the Allen wrench.
  • Then you pull any loose part of the wire with the clamp until the chimney damper is completely closed.
  • With the wrench, you have to seal the clamp fully.
  • You have to cut extra wire with a wire cutter.


Chimney Damper vs. Flue

The flue is a part of a fireplace placed near a chimney. It is a type of metal tube where the smoke or any heat energy goes through the fireplace. It is used for the ventilation process of the fireplace. It helps with the combustion in the fireplace by creating a hotter fire.

On the other hand, the chimney damper is part of the flue. It can be opened and closed to allow the smoke and energy to go through. Generally, it is open when the fire is on and closed when it is not ongoing.

Both chimney damper and flue are related to each other. The flue keeps the ventilation process, and the process can be opened or closed with a damper.


Chimney Damper Cost

The price of a chimney damper can vary according to the type, material, working process of the chimney damper. A good quality chimney damper costs around $200 to $300. But some chimney dampers don’t include a chimney cap. In this case, those cost around $60 to $150.
