Abstract
A furnace system includes an air intake that includes a pipe portion and a seal component configured to couple with the pipe portion. The furnace system also includes an internal drain disposed internal to the air intake. The internal drain includes a trough configured to collect liquid flowing along an inner surface of the pipe portion. The internal drain also includes an opening in the trough configured to guide the liquid collected in the trough to a passage through the air intake to a location outside the air intake.
Claims22
A furnace system, comprising:
- an air intake having a pipe portion;
- a seal component of the air intake configured to couple with the pipe portion;
- an internal drain configured to be disposed internal to the air intake, supported at least in part by the seal component, and comprising a trough configured to collect liquid condensate flowing along an inner surface of the pipe portion, an inner surface of the seal component, or both;
- and
- an opening in the trough configured to guide the liquid condensate collected in the trough toward a location outside the air intake.
An internal drain for an air intake of a combustion air blower of a furnace system, comprising:
- a trough;
- a funnel;
- and
- a tube, wherein the trough is configured to be located internal to the air intake, wherein the trough is configured to collect liquid condensate flowing along an inner surface of the air intake and to pass the liquid condensate through the funnel to the tube, wherein the tube is configured to route the liquid condensate through the air intake to an area outside of the air intake, and wherein the funnel is directly coupled to the tube.
A system, comprising:
- an air intake;
- a pipe portion of the air intake;
- a drain of the air intake, wherein the drain comprises a trough extending circumferentially about a longitudinal axis to form a circle and configured to collect liquid condensate flowing along the pipe portion;
- and
- an opening in the trough configured to guide the liquid condensate from the trough to a tube extending outside the pipe portion of the air intake, wherein the opening in the trough is offset from the longitudinal axis.
