Generated explanation

The illustration shows an oil furnace with cold-air return and hot-air supply ducts and a flue connector extending toward a wall. A barometric damper, identified as a draft regulator, is installed in the flue connector near the wall. A dashed circle and callout identify the damper as a location to check for exhaust-gas spillage. An enlarged view through the flue shows the damper stuck open, with an arrow indicating exhaust gases leaking into the house.
