TK-BF01 Takagi Exhaust Backflow Prevention Kit
The TK-BF01 Vent Damper prevents the backflow of air through the exhaust vent. This is a CSA tested Takagi component. This helps prevent harmful exhaust gases from entering the home, as well as helping to prevent the unit from freezing in areas where cold air can be blown or drawn into the exhaust system. Install this vent damper in accordance with Takagi's installation instructions, and any applicable codes.
