<p>CONDENSATE DISCHARGE DEVICE FOR COMBUSTION APPARATUS A condensate discharge device for combustion apparatus which automatically drains condensate from the combustion chamber or flue while preventing escape of gaseous products of combustion. The device includes a housing having an inlet in its upper end connected to the combustion conduit containing the waste gases of combustion. An outlet tube is disposed in an opening in the lower end of the housing in alignment with the inlet and the upper end of the outlet tube projects a substantial distance above the lower surface of the housing and provides a seat. A hollow plastic ball rests on the seat to prevent escape of gases from the housing. Condensate generated by cooling of the combustion gases flows into the housing and when the condensate accumulates to a level above the seat, the ball will float to permit the discharge of the condensate while preventing discharge of the gaseous products of combustion.</p> |
