Abstract

A multi-poise furnace that is capable of operating in either a vertical or horizontal orientation and having a primary heat exchanger coupled to a condensing heat exchanger, apparatus for collecting and draining condensate leaving the condensing heat exchanger. The collecting apparatus includes a rectangular-shaped collector box connected to an outlet means of the condensing heat exchanger whereby condensate leaving the condensing heat exchanger flows to the lower part of the collector box, and a first drain situated at one corner of the collector box and a second drain situated at another corner of the collector box that is diagonally positioned in relation to the one corner such that one drain is always located in the lower part of the collector box regardless of the furnace orientation, a sheath having at least one drainage slot located around a pressure tap to prevent condensate from blocking the pressure tap, and a plurality of drain diverters for directing condensate originating in the condensing heat exchangers to the center of the collector box.
