Field Controls 7MG1 Double Acting Draft Regulator for Gas - 7-Inch

The Field Controls 7MG1 is a 7-inch double acting draft regulator designed for use with gas-fired heating appliances. This barometric damper automatically regulates chimney draft to maintain optimal combustion efficiency and prevent excessive draft conditions that can waste energy.

Key Features:

• 7-inch diameter double acting design for precise draft control
• Specifically engineered for gas-fired appliances including furnaces and boilers
• Automatic operation maintains consistent draft levels
• Helps improve combustion efficiency and reduce fuel waste
• Prevents over-firing caused by excessive chimney draft
• Durable construction for long-lasting performance

The double acting mechanism responds to both positive and negative pressure changes, providing superior draft regulation compared to single-acting models. This draft regulator installs in the vent pipe between the appliance and the chimney, helping to ensure safe and efficient operation of your gas heating system.
