Flue vent adapter for multi-poise furnace

A flue vent adapter system for a furnace, comprising:

• a flue vent adapter, comprising:
• an inlet;
• an outlet;
• a substantially 90 degree bend disposed between the inlet and the outlet;
• and
• a plurality of transitions to provide clearance for a burner when the flue vent adapter is disposed within a furnace cabinet, wherein the plurality of transitions comprises:
• a first transition disposed between the bend and the outlet;
• and
• a second transition disposed between the first transition and the outlet,
• wherein, moving from the bend toward the outlet, the first transition includes a round shape that transitions into an elliptical shape, and the second transition includes an elliptical shape that transitions to a shape of the outlet;
• and
• a flue vent transition configured to be coupled between the flue vent adapter and a flue vent, wherein the flue vent transition transitions from the shape of the outlet to a shape of the flue vent;
• wherein the flue vent adapter is configured to be connected between an inducer blower and the flue vent transition.

A furnace, comprising:

• a furnace cabinet comprising a cabinet outlet that is configured to receive a flue vent therethrough;
• a burner configured to be disposed within the furnace cabinet;
• an inducer blower configured to be disposed within the furnace cabinet,
• a flue vent adapter comprising:
• an inlet configured to be coupled to the inducer blower;
• an outlet configured to be coupled to the flue vent transition;
• a substantially 90 degree bend disposed between the inlet and the outlet;
• a plurality of transitions to provide clearance for the burner when the flue vent adapter is disposed within the furnace cabinet, wherein the plurality of transitions comprises:
• a first transition disposed between the bend and the outlet;
