ABSTRACT:
A humidifier unit is used with a forced air heating system and includes a water reservoir, a water inlet connection to the reservoir, control means for maintaining the water level at a predetermined depth, and a heat exchanger for heating the water to produce steam. This reservoir has a removable top plate for closing the open top defined by the upper edges of side and end walls. Horizontal flanges extend inward from the upper edges of the reservoir side and end walls and act as a gasket base. Lips extend upward from the inner edges of those horizontal flanges and act as an internal horizontal gasket retainer. Finally, flanges depend from all sides of the top plate and are positioned to surround the upper edges of the side walls and to act as an external horizontal gasket retainer.
