A side terminal for a direct vent operably connected to the outside wall of a structure within which a fireplace is located. The side terminal is configured such that the exhaust duct carrying combustion gases is located a predetermined distance away from a curved surface. The combustion gases impact the curved surface and are smoothly dissipated along the curved surface to atmosphere thereby reducing backpressure in the exhaust duct and enhancing combustion efficiency. |
