In oil-burning appliance combustion products, the dew point is the temperature below which components condense on exposed surfaces.

Explanation:
Dew point is the temperature at which vapor begins to condense into liquid. In oil-burning appliance exhaust, the combustion products include water vapor (and other condensable components). When the flue gases are cooled below their dew point, these vapors condense on exposed surfaces as liquid. This is condensation, not oxidation, sublimation, or evaporation.
