Description
The Weil McLain 383-700-157 Blower Assembly ECO-70/WM97+70/110 is designed to supply combustion air and create the draft required for efficient burner operation in gas-fired boilers. It is placed within the boiler’s combustion system, and it draws air into the burner and supports proper air-to-fuel mixing before venting combustion gases through the exhaust unit in HVAC systems. Its operation works in conjunction with the gas valve, pressure switch and control board to maintain proper ignition and combustion. It restores consistent combustion airflow and heating performance in the systems.
