Description
The Field Controls 46210701 Draft Control MG1 regulates chimney draft by maintaining stable airflow and negative pressure within the venting system during combustion operation. It operates through a barometric control mechanism that automatically adjusts the damper position in response to changing draft conditions, supporting balanced vent performance in HVAC systems such as furnaces, boilers, and oil-fired heating equipment. Designed with a 5″ MG1 configuration, it installs within the vent pipe assembly to assist with controlled exhaust flow. Its operations maintain consistent burner performance, reduces excessive draft conditions, and contributes to efficient heating system operation.
