The damper plate is an essential part of any fireplace chimney, because it keeps cold air from coming into your house and it stops your warm air from escaping out of the chimney. If your old damper plate is warped or rusty, you will need to remove it so you can install a new one. Wait for the chimney to cool so you don't burn yourself. If the chimney is hot, the damper plate also will be hot, because it is made of metal.

Skill level:

Things you need

  • Plastic or tarp
  • Leather gloves
  • Metal container
  • Flashlight or trouble light
  • Adjustable wrench

  1. 1

    Lay down a large piece of plastic or a tarp to cover the floor in front of the fireplace to keep the area clean. Put on a pair of leather gloves to remove the charred wood and throw it into a metal container. Lift the grate out and set it aside.

  2. 2

    Crawl inside the fireplace and shine a trouble light or flashlight up inside the chimney. You will find the damper plate about 1 to 2 feet above your head inside the chimney.

  3. 3

    Locate the four bolts holding the damper plate in place. Turn the bolts counterclockwise with an adjustable wrench to remove them. Put the bolts in a safe place because you will need them to install the new damper plate.

  4. 4

    Turn the damper plate sideways in the chimney. This will allow you to remove it from the rod that holds it in place. Now you can install the new damper plate.

Tips and warnings

  • Check the new damper plate against the old one. The plates have to match in size or the new one will not work in the chimney. If you need to buy one, take the old damper plate to a hardware store. This way, you will have the right one for your chimney.
