Abstract
A humidifier for installation in gas fired fireplaces of the type having an air intake opening and an air outlet opening and an airflow passage there between, in which air is warmed by a fireplace firebox, and exhausted into a room to be heated. The humidifier includes a water supply for supplying water to a water control valve. The water valve communicates with a humidifier pan for filling said pan with water and selectively controlling the water depth in said pan. The pan stores water and is mounted in close proximately to said warmed air such that water in said pan evaporates thereby humidifying the warmed air being exhausted.
