ABSTRACT:
A gas fireplace unit has a combustion chamber in which a gas burner is provided as a heat source, and the gas fireplace unit has a heat exchanger on an upper wall of the combustion chamber. A first set of ports pass through the upper wall into the combustion chamber at a position wherein they are offset from the axis of an exhaust pipe that opens to the heat exchanger. A second set comprising a port or ports is provided aligned with the exhaust pipe, and a damper is mounted to be controllable to cover or uncover the second set from the exterior of the gas fireplace unit. The damper will permit hot gases from the burner to either be directly exhausted out the second set to the exhaust pipe, or when the damper is closed cause hot gasses to be exhausted only through the first set of ports, which provides a greater heat exchange path.
