Fireplace forced air heating apparatus comprises a heat exchanger having a pair of tubes, which may serve as andirons, communicating with a plenum within the heat exchanger and extending outwardly to the front of the fireplace. The tubes connect with duct work including a reversible fan, a hot air register, and a baffle all designed for interchangeable connection to the tubes as required to adapt the installation to various fireplace settings. The tubes and duct work are telescoping to accommodate fireplaces of varying dimension.
