Abstract

One aspect of the disclosure provides a termination for use with a furnace. The termination, in one embodiment, includes a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface. The termination, in this embodiment, further includes an exhaust termination portion extending from the back surface in the exhaust region, the exhaust termination portion capable of engaging a terminal end of a variety of different size exhaust conduits associated with a furnace. The termination, in this embodiment, further includes an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion.

First claim

What is claimed is:

1 . A termination for use with a furnace, comprising:
a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface; an exhaust termination portion coupled to the back surface in the exhaust region, the exhaust termination portion comprising a sleeve capable of engaging a terminal end of an exhaust conduit associated with a furnace; an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion; an air supply termination portion coupled to the back surface and extending from the back surface in the air supply region; and a plurality of stop elements coupled to the back surface in the air supply region, wherein at least one of the stop elements is coupled to the sleeve.

2 . The termination of claim 1 wherein the sleeve comprises a plurality of portions operable to engage a variety of different size exhaust conduits, and wherein the plurality of step portions substantially coincides with the plurality of portions.

3 . The termination of claim 1 further comprising a plurality of freestanding fins in the air supply region.

4 . The termination of claim 1 further comprising a first plurality of mounting posts coupled to one or more of the plurality of stop elements and a second plurality of mounting posts coupled to the sleeve.

5 . The termination of claim 3 wherein at least one of the plurality of freestanding fins is positioned at an angle with respect to a radius from the center of an air supply conduit.

6 . The termination of claim 3 wherein the plurality of freestanding fins extends in a direction parallel with airflow in the air supply conduit associated with the furnace.

7 . The termination of claim 3 wherein the plurality of freestanding fins partially surround the entire back surface.

8 . The termination of claim 1 further comprising a reducing element disposed in the opening.

9 . A method of constructing a termination for use with a furnace, comprising:
providing a face plate including an exhaust region and an air supply region, the face plate having a front surface and an opposing back surface; coupling an exhaust termination portion to the back surface in the exhaust region, the exhaust termination portion comprising a sleeve capable of engaging a terminal end of a variety of different size exhaust conduits associated with a furnace; providing an opening extending through the face plate in the exhaust region, the opening aligned with the exhaust termination portion; positioning a reducing element within the opening to accelerate a flow of exhaust away from the face plate; coupling an air supply termination portion to the back surface and extending from the back surface in the air supply region; coupling a plurality of stop elements to the back surface in the air supply region, the plurality of stop elements comprising a plurality of step portions operable to engage a variety of different size air supply conduits, wherein at least one of the stop elements is coupled to the sleeve; and coupling a plurality of freestanding fins to the air supply region, the plurality of freestanding fins at least partially surrounding the air supply termination portion, extending from the back surface toward an air supply conduit associated with the furnace, and perpendicular to the back surface, and operable to reduce the amount of debris able to enter the air supply region.

10 . The method of claim 9 wherein the sleeve comprises a plurality of portions operable to engage a variety of different size exhaust conduits, and wherein the plurality of step portions substantially coincides with the plurality of portions.

11 . The method of claim 9 wherein the plurality of freestanding fins are independent of the plurality of stop elements and extend further than a first step portion of the plurality of step portions.

12 . The method of claim 9 further comprising providing a first plurality of mounting posts coupled to one or more of the plurality of stop elements and a second plurality of mounting posts coupled to the sleeve.

13 . The method of claim 9 wherein at least one of the plurality of freestanding fins is positioned at an angle with respect to a radius from the center of the air supply conduit.

14 . The method of claim 9 wherein the plurality of freestanding fins extends in a direction parallel with airflow in the air supply conduit associated with the furnace.

15 . The method of claim 9 wherein the plurality of freestanding fins partially surround the entire back surface.

16 . The method of claim 9 wherein the reducing element is removable.
