Field Controls OVD-6 Oil Vent Damper with Control - 6-Inch WMO-1

The Field Controls OVD-6 is a 6-inch automatic vent damper designed specifically for oil-fired heating systems. This energy-saving device automatically closes the vent pipe when the burner is off, preventing heated air from escaping up the chimney and reducing standby heat loss.

Key Features:

• 6-inch diameter fits standard oil furnace and boiler vent pipes
• Includes WMO-1 wall mount control for reliable operation
• Automatic operation opens during burner firing, closes when burner cycles off
• Reduces heat loss up the chimney during burner off-cycles
• Helps improve heating system efficiency and lower fuel costs
• Durable construction designed for long-term reliability
• UL listed for safety compliance

The OVD-6 installs in the vent pipe of oil-fired heating equipment and operates automatically through the included WMO-1 control module. By preventing warm air from continuously flowing up the chimney when the burner is not running, this vent damper helps maximize heating efficiency and reduce energy waste. Ideal for residential and light commercial oil heating applications.
