Instructions to Replace a Chimney Damper

All chimneys are equipped with dampers to prevent the heat from escaping from the home when the chimney is not in use. The damper must be opened before a fire can be lit in the fireplace. The damper may need to be replaced over time, but it is fairly easy to do.

Instructions to Replace a Chimney Damper

1. Remove all of the burned ashes and wood from the fireplace. The ashes can be easily removed by using a garden trowel.


2. Put on some heavy-duty work gloves and remove the grate from the fireplace and set it outside where it cannot come in contact with any of your furnishings.


3. Use a shop vac to remove any ashes and debris remaining in the fireplace. You want to make sure that the work area is as clean as possible.


4. Shine a flashlight inside the fireplace to locate the damper, which is normally approximately a foot above the opening of the fireplace.


5. Remove the bolts that are holding the damper onto the damper rod. This should be done by using an adjustable wrench and turning the bolts counterclockwise.


6. Turn the damper sideways and pull it off the rod and out of the chimney.


7. Take the old damper with you to the hardware store to purchase the new one. This should be done to make sure you are purchasing the right size. 


8. Put the new damper on the rod and secure the bolts. You can use the same bolts that you removed from the old damper.
