Abstract
A fireplace apparatus for a building includes a firebox, and a plenum arranged with an exterior surface of the firebox. A blower is arranged with the plenum to force air through the plenum and a plenum exhaust vent is configured to release the forced air from the plenum. A method of pre-heating air for a building fireplace includes selecting air admitted from inside the building through an interior inlet port into a manifold and through a plenum until the firebox reaches a selected temperature, and selecting air admitted from outside the building through an exterior inlet port into the manifold and through the plenum when the firebox reaches or exceeds the selected temperature.
