Abstract
A condensate pan for a condensing furnace includes a main chamber to receive exhaust gases, a condensate trap separate from the main chamber and internal the condensate pan and a main drain.
Claims19
A condensate pan for a furnace comprising:
- a chamber to receive exhaust gases;
- a plurality of condensate traps separate from the chamber and internal to the condensate pan, the plurality of condensate traps being configured and positioned to extend from the chamber to enable a condensate trap of the plurality of condensate traps to collect condensate for each pre-determined orientation of the furnace, and a pair of condensate traps of the plurality of condensate traps being positioned on opposite sides of the chamber;
- a plurality of main drains, each condensate trap of the plurality of condensate traps having a corresponding main drain of the plurality of main drains;
- and
- wherein the plurality of condensate traps are configured and positioned to have a cruciform shape.

A condensate pan for a furnace comprising:
- a bottom wall;
- a top cover;
- a side wall intermediate the bottom wall and top cover;
- a plurality of baffles extending between the bottom wall and top cover;
- a main chamber being bounded by at a least a portion of the bottom wall, top cover, side wall and the plurality of baffles;
- the main chamber is configured to receive at least one heat exchanger outlet from the furnace;
- a plurality of trap portions, each trap portion of the plurality of trap portions being separated from the main chamber by a corresponding baffle of the plurality of baffles, the plurality of trap portions and the main chamber being configured and positioned to have a substantially cruciform shape, and wherein a trap portion of the plurality of trap portions is enabled to collect condensate during operation of the furnace;
- and
- each trap portion of the plurality of trap portions includes a main drain positioned to allow collected liquid condensate to exit the trap portion.
6 more elements
A furnace having a plurality of mounting positions, the furnace comprising:
- a burner;
- a heat exchanger to receive combustion air from the burner, the heat exchanger having an outlet;
- a blower configured to distribute supply air across the heat exchanger;
- a vent;
- an inducer positioned to evacuate exhaust from the outlet to the vent;
- and
- a condensate pan positioned intermediate the outlet and the inducer, the condensate pan comprises:
- a heat exchanger aperture to receive fluids from the outlet;
- an inducer aperture to provide fluids from the condensate pan to the inducer for transmission to the vent;
- more than two internal condensate traps, the more than two internal condensate traps being configured and positioned to enable a different internal condensate trap of the more than two internal condensate traps to collect condensate for each mounting position of the furnace;
- a plurality of main drains, each internal condensate trap of the more than two internal condensate traps having a corresponding main drain of the plurality of main drains;
- and
- wherein the more than two internal condensate traps are configured and positioned to have a substantially cruciform shape.
