Field Controls 4RC Draft Regulator for Oil Wood Coal Furnaces - 4-Inch

The Field Controls 4RC is a 4-inch draft regulator designed to maintain proper chimney draft for residential heating systems burning oil, wood, or coal. This automatic draft control device helps optimize combustion efficiency by regulating the amount of excess air entering the flue system, preventing over-firing and heat loss up the chimney.

Key Features:

• 4-inch diameter flue connection for standard residential applications
• Compatible with oil-fired furnaces, wood stoves, and coal-burning appliances
• Automatic counterweighted damper adjusts to maintain consistent draft
• Reduces fuel consumption by preventing excessive draft conditions
• Helps prevent downdrafts and improves heating system efficiency
• Durable construction for long-lasting performance

Proper draft regulation is essential for safe and efficient operation of solid fuel and oil-fired heating equipment. The Field Controls 4RC installs in the flue pipe between the appliance and chimney, automatically opening and closing to balance the draft as chimney conditions change due to weather, temperature, and other factors.
