5-7"dia 6.5"H-W 8"L SS Barmtc Drft Cntrl: Natural Gas and Oil, For 5 in_6 in_7 in Duct Dia, 8 in L
Barometric draft control dampers automatically open and close in response to pressure changes in the connected exhaust duct. They help optimize the combustion by regulating the draw in the exhaust. This increases the heat transfer in the heat exchanger and helps ensure complete combustion. Their configuration is determined by the duct size, fuel used, and system airflow needs.
