Field Controls (OVD) oil vent damper reduces off cycle losses through oil fired heating appliances. When the appliance is in a standby mode, heat escapes up the chimney. The heat comes from the appliance and the conditioned space. To significantly reduce these losses, install a Field Controls Oil Vent Damper. The damper is installed in the vent system between the draft control and chimney. The WMO-1 blocked vent safety shut off installs between the draft control and appliance. When properly installed, the damper opens before the burner fires and closes after the burner shuts off.
