Barometric Double Acting Draft Regulator Control for Oil, Gas/LP or Coal Appliances

The Field Controls 02724001 MG-1 Barometric Draft Control is a double-acting draft regulator engineered for stable and efficient combustion performance in natural gas, LP gas, oil, and coal-fired heating appliances. Designed to maintain constant draft pressure within venting systems, the MG-1 compensates for variations in temperature, barometric pressure, and wind conditions. This control ensures consistent combustion air delivery, proper flue performance, and compliance with industry combustion and venting standards.
