A direct-fired kiln for drying lumber having a reversible powered air-mover mechanism for producing air circulation within the interior of the kiln in either of opposite directions. Selectively controlled air withdrawal conduits returning air to a fuel burner outside the kiln are adjusted so that air is always withdrawn from the side of a load within the kiln where circulated air is exiting from the load.
