How to Install a Fireplace Damper Lock
A fireplace damper controls the amount of moisture and oxygen that enters into your fireplace, and it controls how the gas emissions exit through the chimney flue. It helps to control the amount of combustion during the burning of the fire. A fireplace damper lock will lock the damper in place so that you cannot close it while the fire is burning and thereby allow harmful gases to enter the room. Follow these steps to install your fireplace damper lock.
Step 1 - Open the Fireplace Doors
Get into the fireplace pit by opening up the doors. Remove the screen and clean the bottom of the fireplace. Remove any ash or soot.
Step 2 - Install the Fireplace Damper Lock
Reach up to the damper and install the lock. Follow the manufacturer's guidelines on how to install the lock. You can usually attach it with a couple screws and a Phillips screwdriver.
Step 3 - Close Up the Fireplace
Put the wood and the rack back into the fireplace and close the doors.
