The installation of a fire damper
The fire damper has the main purpose to control the amount of moisture and oxygen that enters a fireplace. It also controls the exiting of gas emission through the chimney. The safety lock that prevents the damper from closing while there is a fire burning ensures that the toxic gases are always eliminated from the room.
The fire damper is designed so that if a fire starts it cannot spread through the walls, floors and partitions. Once the fusible links opens the fire damper closes and the steel frame stops the fire from getting farther into the building.
There are two damper types available: the manual damper and automatic damper. The first one needs manual adjustment every time a fire is started to control the air flow and the automatic one adjusts itself only based on the temperature.
Safety regulations force you to have a fire damper in all buildings.
First you need to analyze what kind of damper you need. Analyze each mode and price from each manufacturer until you make a final decision. Choose from vertical dampers used in walls or horizontal dampers used in ceilings. Make sure you get the damper at the size that fits your installation place.
After you have decided where you want to install the damper secure the damper to the sleeve with metal screws. You need to identify if you have a construction with wood studs. If so you will need to fill around the openings with filler pieces to make sure the room is sealed. Install the damper based on the manufacturer’s specific instructions.
Check the damper to see how it works once you are finished working on it. Leave a fire burning for an hour and see how it manifests.
